9 Things You Should Know Before Replacing Windows in Your Home

Replacing or installing windows can be stressful for many homeowners. Whether it’s deciding on which type of windows are best for you, choosing the right type of glazing, or even considering if you need new windows at all, there are a lot of factors to consider. To make the process easier for you, we asked the experts some of the most common questions homeowners have when it comes to replacing windows in their home.

So, how do you know if you need to replace windows in your home? Perhaps you recently noticed that one or more of your windows have become difficult to open, a common problem, especially with wood windows. Maybe there’s too much sound pouring in from the street in front of your home, or condensation has begun building up between your double glass panes. Or, maybe you just realized that you’re spending more money each year in heating and cooling costs. These are the most common problems homeowners face and are usually good indicators that it’s time to replace your windows.

1. How do I Know if Moisture is the Problem with My Windows?

When moisture accumulates on the inside of the window, it may be a sign that your windows are starting to fail. If you are seeing condensation or mold inside the window and/or moisture pooling on the window sill, then you have reason to be concerned.

Moisture issues typically show up in the form of fogging between the window panes or condensation on the side of the window facing your home’s interior. Double pane windows are held in place with a special seal which, over time, can harden and then crack. Particularly with vinyl windows, the window frame expands in the heat and contracts during the colder months. This pattern of expansion and contraction causes this seal to crack, resulting in fogging and, ultimately, what we call a failed window.

If you’re experiencing these issues, there are some things you can try before replacing your windows. Make sure you have a moisture barrier in the crawl space under your home. Your whole house must work against cold air rising from the ground below. Ventilate properly when cooking, showering, and doing laundry. Use a dehumidifier if you have one and, if you have blinds, raise them to allow air to circulate against the window. If you have tried these solutions and you’re still seeing moisture inside your windows, it might be time to replace your windows.

2. How Long Do Windows Last?

Although there are very high-quality windows available in residential new construction and remodeling, it’s difficult to determine how long the windows will last based on appearance and warranty alone. Many economy windows provide lifetime warranties, giving the impression that they will last forever. However, these cheaper windows tend to be lower quality simply because they were mass-produced in standard sizes.

The failures that occur most frequently with economy windows in the first few years are ones with insulated glass that lose their seal and result in operational issues caused by substandard balance systems. If this happens you’ll notice that the window becomes difficult to lift open or you may start to see fogging occur between window panes.

Also, improper installation can result in a short lifespan of a window as well. This is especially true in remodels where windows are better-ordered in custom rather than standard sizes. Poor installations can result in holes in the envelope of your home which allow for wind, water, and insects to penetrate and cause damage to your window frames.

If you’re considering replacing the windows in your home or inspecting the condition of windows in a house you’re interested in, you’ll want to be on the lookout for fogged glass, damaged frames, and drafty rooms.

3. Should I Replace All of My Windows At Once?

The answer to this question depends largely on the budget of the homeowner. While windows are often replaced in two or three stages (typically starting with the front of the house and then moving to the back, and finally to the upstairs), it is also important to know that once you order ten or more windows, the cost per window tends to remain the same.

4. How Do You Choose Windows For Your Home?

The decision on which windows to install in your home is a daunting one but can be broken down into four considerations: material, type of window, glass package, and budget.

Window Materials
Most window frames are made of one of three materials: wood, fiberglass, or vinyl. Wood windows are a good choice if you’re looking to match the window to an existing wood trim on your home’s interior. The most durable of the three materials, fiberglass windows (also known as composite windows) will typically have the longest lifespan. Finally, vinyl is the most popular by far, making up about 75 percent of all windows sold, and are available in a number of different colors.

Type of Windows
There are a handful of options available for the type of window you can install in your home as well. Double-hung windows are the most popular of the group. These are designed to tilt into your home and can be cleaned without the need for ladders or stools. Sliding windows are a wider but shorter type of window and are also a good choice depending on your needs. Lastly, crank-out windows should also be considered as not only can they be used in a variety of different openings but are also the most energy-efficient option as well.

Glass Package
Regardless of the material or type of window you choose, the glass package is the most important part of your decision. Low emissivity coatings (Low-E) are recommended as they play a large role in making a home more energy-efficient by allowing heat into your home in the colder months and reflecting heat away from your home during the warmer months. This means that you save on heating and cooling costs.

Your Budget
When it comes to window shopping on a budget, feel free to choose the cheaper material and style options but do not take shortcuts with the glass package as a good Low-E coating will save you money in the long run.

5. How Much Do New Windows Cost?

Calculating the cost for new windows can be tricky as there are a handful of factors that contribute to the final price. The cost to replace windows will vary depending on size, amount of windows needed, style and quality. It’s important that you know what you’re looking for before you start calling contractors.

Typically, window frames are made of either wood or vinyl. Cheaper than wood, vinyl frames also have a longer life span and tend to be easier to clean. Wooden frames tend to be more expensive and more challenging to maintain as they can peel and rot as a result of water damage.

For a standard-size, double-hung, double-pane (energy efficient), vinyl window, expect to pay between $450 and $600, including installation. Wood windows are more expensive, costing between $800 and $1,000 per installation.

If both the window and frame have to be removed down to the studs, be prepared to add at least $50 to $100 per installation. This is referred to as “new construction” windows or “full-frame” replacement windows and requires more work.

6. How Do You Measure for News Windows?

The way in which homeowners should measure for new windows depends on their specific needs.

The main thing to keep in mind is that the window will be a ¼” less than the rough opening, between the framing timbers. If you have ¾” jamb extensions on both sides, then measure between them then add 1 ¼” to that measurement.

On a retrofit installation, the existing mainframe typically remains. Measure between the smallest point of the existing mainframe, then deduct ¼” from that measurement for the width and the height.

7. How Do I Determine Which Type of Glazing I Need on My Windows?

There are essentially two main types of residential glass: a 2-coat Low-E and a 3-coat Low-E. Each type is typically available with or without argon or krypton gas filling.

In climates where cooling during the majority of the year is the biggest concern, a 3-coat Low-E is the best option as this reduces the most heat gain from the sun and offers the best U-value, lower SGC/SHGC, and U-value/U-factor numbers.

In contrast, climates requiring more heating during the year, the 2-coat Low-E will allow some heat gain during the winter months but still provide a good U-value for insulating against the cold.

Additional items to consider for the type of Low-E used on glass is the hue the Low-E has. 3-coat Low-E glasses often have a more pronounced hue registering as a bluish or greenish cast on the glass, whereas 2-coat Low-E glasses tend to be clear with little to no noticeable hue. The more coats of Low-E a glass pane has the less light is going to transfer through.

8. When’s the Best Time to Buy Replacement Windows?

Because the weather is warmer, late Spring, Summer, and early Fall are the most popular times for homeowners to replace their windows. Although replacing a window can be quick, having a window removed for roughly a half to full hour can have an impact on your home’s temperature, making the warmer months ideal for anyone who can’t stand the cold.

However, if you can tolerate the cold of replacing windows during the winter months, then you could save some money by opting to wait for the inclement season. The other benefit of replacing windows in the first part of the year is that you get to enjoy their benefits throughout the summer, which is important given newer windows’ ability to reduce heat gain during the hot summer.

9. How Do I Prepare for a Window Replacement?

Prior to an installer’s arrival, homeowners should remove any curtains or blinds from their openings so that the window installer has access to the interior to set and caulk the windows.

As installers need access to the interior of the windows for replacing, homeowners should also move any furniture to at least 3 feet away from the openings, as well as anything of value located around the windows. If there are alarm systems on the windows, the alarm company also needs to be notified of the upcoming work. The sensors will need to be removed and the alarm company may need to come to the house so that they can be reinstalled.

On installation day, probably the most important thing a homeowner can do is relax, run errands or return to work and let the installers do their job. This will limit any potential stress involved for both the homeowners and installers alike.

Window Replacements by Type

On average you’ll spend anywhere from $50 to $1,000 or more depending on the style you choose. In addition to the price of materials, you’ll spend an average of $200 per window for labor.

Before buying, make sure the window’s size, function and look are what you want. We’ll discuss each in more detail below. Here are the most common styles for a home:

Window Costs by Style*

Type	Material Price Only
Double-Hung	$150 — $650
Single-Hung	$100 — $400
Fixed & Picture	$65 — $700

Double-Hung Replacement Windows Prices

Double-hung types run $150 to $650 each. It looks exactly like a single-hung but allows the upper and lower sashes to move. Explore the differences and costs between a single and double-hung window.

• Increased circulation occurs when lower and upper sashes are open. There is no change in the total open area, but higher and lower openings let in fresh air while allowing stale air to escape.
• Cleaning on upper floors is easy. Both sashes lean inward for easy access and safety.

Single-Hung Windows

A single-hung type runs from $100 to $400 each. This classic, old-fashioned, vertically-opening style is the most popular. Only the bottom pane, called the sash, slides.

• Sometimes incorrectly referred to as “fixed,” with is a non-operational unit.
• Use on the ground floor only. Cleaning on higher floors can be dangerous since it requires leaning out to reach the exterior of the upper sash.

Picture Window Replacement Cost

Picture styles run anywhere from $300 to $1,200 or more depending on the size.

• Usually fixed in place. Some include opening side panels for ventilation.
• Often requires custom sizing

Casement or Awning Window Replacement

This hinged variety, that opens like a door, runs $150 to $1,000 depending on the size and material type. A casement style hinged to the top is called an awning, while a hopper has bottom hinges.

• Opens inward or outward.
• Opens via a crank that doubles as a lock. Many models offer separate locks for added security.
• Resists the wind blowing it open or closed due to the crank mechanism.
• Gets maximum ventilation because it can swing completely away from the frame.
• Since the entire panel can swing open, larger ones may have a large fixed pane in the middle with left and right openings at either end.

Sliding or Folding

Sliding types run $150 to $800 each. Folding types are custom installations and range anywhere from $500 to $900 per linear foot, including labor.

• Includes two sashes (one sliding horizontally over a stationary sash).
• Sliders (sometimes called gliders) are often used for larger applications.
• Increases view with smaller sills and cases.
• Use on the ground floor only; cleaning on higher floors is dangerous since it requires leaning out.

Storm

Storm windows cost $50 to $300 each including labor. Most homeowners spent $5,000 on average to put storms on all windows.

• Helps protect the trim of your windows.
• Increases energy efficiency.
• May increase resale value.

Bay and Bow Window Costs

A bay window replacement costs $1,800 on average. They add square footage to the floorplan, increasing the home’s value and space. Bay types are three panes joined at an angle which extrude from a living space or bedroom.

Bow window replacement estimates run from $1,000 to $4,500, not including installation. They are like bay styles but have a minimum of five panes rather than three. They often don’t extend outward as far as bow styles do and therefore provide less square footage but more window area with more light.

Custom Replacements

Custom work is always more than standard replacements starting at $1,000 each. Custom sizes and installations are common among older homes where standard opening sizes weren’t used.

Pocket Replacement Window

Pocket window replacement pricing varies by project as they are almost all custom work. Pocket types use the existing frame, removing only the old glass. A new unit is custom made to slide snugly into that opening. It takes the least amount of time to install but reduces visibility. You’ll literally have one frame sitting inside of another.

Energy-Efficient Window Replacements

You’ll spend an average of $120 to $1,200 each. High-quality brands go even higher in price. Generally, the more you pay the more efficient they are. They start at simple, double-pane varieties with an Energy Star rating and go up to triple-pane, high-efficiency types with a low-e coating.

• Low-e coatings add 10%-15% to the price.
• Vinyl, wood and fiberglass are the most energy-efficient.
• Great option for the environmentally-conscious homeowner.
• Energy-efficient styles save you between 7%-15% on home energy bills. But it isn’t always worth the extra investment.
  • For example, if your annual heating and cooling bill runs $2,000, you’ll save $140 to $300 per year. If you spend $5,000 more on the project than standard windows would have cost, it’ll take you somewhere between 16 and 50 years to make up the extra expense.

Average Cost to Replace Windows

Replacing a window costs an average of $300 to $700 each. This assumes that the replacement is going into an existing and structurally sound frame on a ground floor. Replacing everything in a typical three-bedroom, single-story home with ten openings can range from $3,000 to $7,000. This price can easily double for a two-story home.

Window Replacement Cost Per Window

You’ll pay an average of $40 per hour for labor orabout $100 per unit. In some cases, you’ll pay as much as $300 each, depending on size, location, accessibility and the overall time the job takes.

Average Window Replacement Costs by Amount*

Amount	Material & Labor
5	$1,500 — $3,500
10	$3,000 — $7,000
15	$4,500 — $10,500
20	$6,000 — $14,000

*For high-end and custom work, add 25% to 50%.

Cost of Replacing Windows by Size

There are hundreds of sizes available direct from manufacturers, through your professional and through most big box home improvement stores. Sizes affect both material costs and installation times. Expect a large bay style to require two pros and additional installation time than would be required by a small bathroom window replacement.

With so many sizes, it’s impossible to give exact pricing. For the best estimate for your specific project, contact a window installer near you today.

Labor Cost to Replace Window

Most installers average $40 per hour with a typical range of $30 to $65 per hour. Expect to pay more in urban areas with higher costs of living, such as San Francisco and New York. A good rule of thumb is to add between $100 to $300 per unit for installation with complex installs reaching closer to $600 or more.

Keep labor rates down with higher volume jobs. You’ll pay less per window the more you replace at the same time. In addition to the materials and hourly rates, contractors must also account for travel time, fuel, setup, cleanup and disposal fees. Overhead remains close to the same whether you’re changing two or ten.

Complexity of the install, age of the home, accessibility and location affect this price. For example, one in a single-story suburban home, built in the last 20 years, might be a quick two-hour job per unit while a third-floor replacement in a row home in Manhattan may take six hours or more.

Cost to Replace Windows in an Old House

Old homes (70 years or older) can double or triple project pricing. They each come with unique challenges, such as:

• Custom pieces made to fit nonstandard sizes.
• Repairing or replacing rotted or broken trim.
• Match historical architecture.
• Removing counterweights.
• Upgrading to current code standards.
• Filling empty areas with insulation.

Changing Out Parts

Repairing a window costs less than installing a new one, or about $325 on average. Repairs also helps maintain the character of older homes and unique architectures.

Window Change Cost by Location

While most install locations don’t make a significant difference in pricing, there are a few areas to note.

• Basement window replacements: $250-$1,000+depending on the number of alterations needed.
• Basement egress windows: $2,500-$5,000+.
• Bathroom or Bedroom: $300-$700 each.
• Sunroom: price varies depending on the size.
• Foyer or dining room: $300-$700 for installation. Large picture, bay and bow varieties can double or triple that price.
• Replacing on upper floors increases the time it takes to access them from the outside. Add an hour of work per unit, or about $40.

Cost Factors

Other than the labor and unit price, other factors affecting price include:

• The need to alter an existing frame.
• Double- or triple-glazed.
• Insulating gases in double- or triple-glazed.
• Exterior dressing (decorative awnings, etc.).
• Remoteness of the job site.
• Time demands on the contractor.
• Unforeseen structural deficiencies.
• Profit: A contractor must make money to stay in business just like anyone else. A profit margin of 25% is realistic. It will vary by location with margins up to 60% or more.

Full Frame Window Cost vs. Retrofit Replacement

New construction	Replacement
Labor: $150 — $800 each	Labor: $100 — $300 each
Nail fin frame	Slides into existing hole
Requires trim work	No finishing work needed

Installing new windows costs $5,850 on average. But understanding the two types of windows beforehand can save you thousands in labor.

• The only physical difference between the two is a nail fin, a flange around the edge for attaching directly to the studs, which is found in new construction units.
• Retrofit or replacement windows are 10%-15% cheaper than new construction and require less labor to install.

Retrofit or Replacement

• For existing homes, always use retrofit or replacement types.
• 10%-15% more expensive for materials but take far less time to install.

Full Frame or New Construction

• In existing construction, this can increase increases price by 50%-100% because the pro must tear out the old frame. In existing structures, this can increase the project price of an average one-story, three-bedroom home project by $5,000-$40,000.
• For new construction projects. Only used in existing buildings when stripping the wall to the studs for a remodel or due to damage.

Additional Factors

In addition to the added labor, installing a new construction unit into an already existing home can require additional side work, including:

• Framing costs: $1,000-$2,500
• Insulation costs: $450-$3,000
• Cost to repair trim: $300-$1,000
• Siding repair pricing: $300-$1,100
• Costs to install drywall: $1.50 per square foot

Best Replacement Window Brands

There are dozens of brands available depending on the region. In most cases, your contractor will help you determine the best brand for your home. Whether it’s a factory direct installation or a third-party, all of these windows come with warranties, many of them transferable. Any third-party contractor may warranty labor.

• Wallside Windows: $300-$500. Vinyl replacement company that both produces and installs its product. They come with a 35-year warranty.
• Feldco: $300-$700. Available in Wisconsin, Iowa, Indiana and Illinois. They both make and install their products. 20-year warranty.

DIY Estimates

It’s unlikely that you will save any money doing this yourself. Contractors can purchase materials at wholesale, while you will most likely have to pay retail price. Further, professionals know what to measure and how to correctly measure it.

The tools and knowledge to correctly do this work belong to the professionals—and they do the job so often that they can usually perform the labor in a surprisingly short amount of time. In fact, by the time the average homeowner has determined the size they need and compiled a basic list of tools and materials required, a professional can be halfway through the work.

Why Hire a Professional?

There are several advantages to hiring a professional window installer. A professional will know how to deal with the following issues and any others that may arise over the course of a job:

• Mold: A major health issue, particularly in humid regions, this fungus can destroy wood.
• Rotted wood: Wood that is rotted or damaged by pests can severely affect a window’s integrity.
• Structural integrity: All exterior walls are load-bearing. Only a licensed contractor should make changes to load-bearing structures.
• Measurements: It’s not a matter of simply measuring the opening length by width. Measurements must account for trim, pulleys and stop strips. If these aren’t measured correctly, it won’t fit.
• Age and codes: Older homes may not have standard-size openings, so replacing them requires removing the frame and installing a new supporting structure. If your home is significantly older—a Victorian-era home, for example—modifications must meet current code requirements.
• Type of glass: Depending on the location, tempered or safety glass may be required by law.
• Location: Ordinances and codes could dictate the placement of your windows. Ask your pro what is required in your jurisdiction.

Getting a Professional Window Replacement Quote

It’s recommended you get at least three quotes before you decide to hire a window replacement professional. The quote won’t typically include the frame. But expect the following:

• The use of sheets and drop cloths to protect your home’s interior around the work area.
• Including disposal fees.
• Remove and replace any rotted or damaged wood. Since the contractor won’t know exactly how much, if any, will need to be replaced until the work begins, this amount can vary. This is an important matter to discuss with the contractor because extensive repairs for bad wood can easily add $3,000 to your total.
• New Installation. This should specify brand, style, size, any screens, color of the casing (if needed) and other details.
• Insulation and weatherproofing. Filling in gaps around the opening.
• Clean-up and disposal. Both interior and exterior work areas and removal of all job-related debris.
• A guarantee. Be sure to keep a written copy of the full guarantee for your own protection.

How much is window glass replacement?

Window glass replacement costs $270 on average. Expect to spend $3 per square foot for the glass and about $50 to $75 per hour for the contractor.

Are replacement windows worth the cost?

Replacements are often worth the price. You’ll get approximately 70% return when you sell your home. Depending on how long you live there, the energy savings can make up more.

How often should you replace windows?

You only need to replace them when they show rot, lose all insulation value or break. Many homeowners of older properties upgrade from single pane to double pane to reduce utility bills. There are other benefits of replacing windows to consider.

How can I get the lowest cost on window replacements?

The best way to get the lowest price is to do all your windows at the same time and get at least three quotes.

How much does a mobile home replacement window cost?

Mobile home units run from $100 to $300, quite a bit cheaper than most traditional homes.

How much is a condo window replacement?

Replacing condo windows averages $300 to $700 per unit. However, HOA’s vary on rules governing who is responsible for replacement, what types are allowed and if they must match across all condos. Check with your HOA before doing any work.

What is the cost of replacing windows and frames?

It’ll add an additional 30% to 100% to replace the frames depending on what finishing work you need. See our list, Additional Factors, above for more cost information.

How much is it to swap out windows and doors together?

It’ll cost you slightly less per window and door to swap them out together. Your actual savings is going to vary depending on the size of your home, number of entryways, location, accessibility and the contractor you hire. Get multiple quotes for the best rates.
