Choosing the best Windows and window-related services for your home

Last Updated August 2021

We’ve all heard about the benefits of buying new windows for the home. New windows look great, enhance energy efficiency, and provide comfort in both the winter and summer months.

Perhaps you’re reading this because you want to outfit your home with a great new set of windows. If so, you may have questions. How much do new windows cost? What type of windows should you buy? Whom should you contact to have your new windows installed?

At BestReviews, our mission is to provide you with the answers to these questions and more. We want to help you make your purchases with wisdom and confidence. We scrutinized the window market and studied window-installation options in order to learn all about them.

In this shopping guide, we will explore your options with you, from which type of window style you might prefer to which type of installation process is right for you.


Newer windows can dramatically boost your home’s resale value.

What’s your preferred window style?

Most new windows fit into one of three style categories: casement windows, double-hung windows, and picture windows.

Certain window styles fit better in particular areas of the home. For example, you might enjoy having an easy-to-maneuver casement window in your bedroom, but you probably wouldn’t want to have a picture window in your bathroom.


Before ordering replacement windows, you’ll need exact measurements of your current windows. Your contractor can take these measurements for you.

How will you frame your windows?

When shopping for new windows, you can choose from four different types of window frames: vinyl, wood, cladding, and aluminum. Understanding the benefits of each frame type will help you decide which is best for your home.

Are you looking for new windows that are easy to clean? Vinyl material in the casing of a new window will save you quite a bit of time on maintenance.

What type of glass will you choose?

Windows have come a long way since their single-pane days. When you buy new windows, you have the option of purchasing double-pane or triple-pane glass. The effectiveness of a window’s glass panes is measured by its solar heat gain coefficient (SHGC), its U-factor, and its R-value.


Multi-pane windows have argon gas between the panes. This gas limits the degree to which UV rays can reach inside your home. To learn more about how effective a particular window product would be at shielding you from UV rays, check out its SHGC value.


The argon gas between the panes also helps prevent heat from escaping your home. The degree to which a window product does this is known as the U-factor. The lower the U-factor, the more energy-efficient the window is. A U-factor of 0.25 is an excellent figure.


You can check out a window product’s R-value to determine the overall efficiency of the glass. A higher R-value signifies a more efficient window. A window with an R-value of 5 is generally thought to be a highly energy-efficient window.


Windows are very heavy, and successful installation often requires the help of more than one person. Keep this in mind if you’re considering window installation as a DIY project.

Will you replace or repair your windows?

Perhaps you’re debating whether to replace or repair your current windows. It’s easier to make this decision if you know approximately how old your current windows are.

Windows that are a couple of decades old are the best candidates for replacement. However, if you moved into a home recently, you might not know the age of your current windows. Your windows provide clues about their age, though. Ask yourself these questions to determine the approximate age of your windows.


If you see water condensate between multiple panes of glass, one of the seals on the window is compromised. You may wish to replace this window.

Tips for window repair

If you don’t want to undertake the work and expense of replacing your home’s windows, you can perform repairs. Consider these tips.

If you can’t determine whether your windows need replacement or just a few repairs, hire a trusted contractor to look at them. He or she can help you make the determination.

Some windows simply aren’t worth repairing. For example, if you see rot on the wood casing of a window, you’d spend a lot of money just to repair it. A new window may be a better use of your money in the long run.

Finding a trustworthy window-replacement service

You have a few different options for new window installation. Consider the following ideas to help you find the best solution for replacing your windows.

Window companies

Some companies that sell windows also specialize in window replacement. The process is fairly simple when working with a window company, as you only have to deal with one entity. Just make sure the company has a good rating with the Better Business Bureau and/or with local customers.

When comparing window companies, make sure you’re looking at similarly constructed products. And always ask whether the quoted price includes all labor. Using a company like this for window installation usually results in the highest cost.


Another option for window installation involves hiring a contractor to do the work. In this scenario, you purchase new windows at a local hardware store, which would handle the delivery. The contractor would then perform the window installation.

You’ll have a lot more choices in brands of windows, as some window companies only offer one brand of window. Just make sure to partner with a competent contractor that you trust.

On your own

If you have some experience with home-improvement projects, you can purchase and install the windows yourself, saving the most money.

However, new windows can be heavy, making it difficult for one person to do the work. And the windows must be perfectly squared up before they are installed.

Completing this type of work successfully will be very difficult for novices. Only choose this option if you have experience installing windows.

Checking references

If you opt to go with a window company or contractor for the installation of your new windows, be sure to request written bids from at least three competitors. The bids should spell out all hardware and labor costs, as well as a time frame for completing the work.

Make sure the window company or contractor has plenty of references, and physically visit the homes where the work was done to inspect it yourself.


Ask your window installer whether he or she will install a new window immediately after removing an old window. This method minimizes your home’s exposure to the elements.


Q. How quickly will I see a return on my investment in new windows in terms of energy efficiency?

A. Actually, you shouldn’t decide to replace your older windows solely on the hope that you’ll save money on energy. In general, new windows provide roughly a 10-percent savings on your energy bill. This means that it would take an average household several decades to recoup their new-window costs in energy savings.

In addition to helping you shave a small percentage off your monthly energy bills, new windows will enhance the aesthetic appeal of your house. They’ll also likely be easier to clean. These benefits, in combination with slight energy savings, should help you justify the cost of new windows.

Q. How long does it take to install new windows?

A. The installation process varies from contractor to contractor and from home to home. An experienced installation team could complete the job in a day or two. A single contractor working on an older home with tricky windows could take a couple of weeks. Regardless, the company or contractor you hire should be able to give you a realistic estimate on the amount of time required.

Q. How much time will I need to spend preparing my home for window installation?

A.  Window installers will need access to both the inside and outside of your home. Fortunately, the tasks you must complete before the window installers arrive shouldn’t take very long. Here’s what you need to do.

Q. How much does window replacement cost?

A. With labor included, replacement windows can cost anywhere from $250 to $1,000 apiece, although you may pay more or less in your area.

To save money, you may wish to try replacing windows in the winter. Most contractors and window companies have fewer jobs at this time, so you might trim a bit off your bill this way.
