What Should You Consider When Deciding Between the Best Window Installers?
Some of the key factors to consider when finding the companies that provide the best replacement windows are certifications and insurance, customer reviews, warranties, and window selection. Read more about each of them.
Certifications and Insurance
All window installation companies should have proper certifications, licenses, and insurance for your state. Don’t work with an installer that doesn’t have the proper documentation. Working with an unlicensed installer could result in improper installations and legal issues. If you work with an independent window installer, check that the company is certified to install your selected window brands. Many window manufacturers maintain a network of certified installers to install their products. This ensures the windows are installed to the company’s specifications and instructions.
Reviews
Read online reviews from the Better Business Bureau (BBB), Google Reviews, Best Company, and other reliable customer review sites. Look for reviews that comment on the product quality, sales team, installation process, and customer service experience. Check for customer satisfaction complaints regarding warranty claims and window repair services. We also recommend speaking to neighbors, friends, and family who have completed window projects to get a feel for their experiences with their selected installer.
Warranties
Window warranties provide additional peace of mind as they cover the glass, window frame, and other components if something goes wrong. You may receive a separate manufacturer’s and labor warranty if your window manufacturer and installation company differ. Review each warranty in detail and ask questions. Get clarification about your warranty length, transferability, and specific coverage for the window frames, glass, hardware, and labor.
Windows Selection
Your windows may be manufactured in-house or by a third party, depending on your selected installer. If the products are manufactured in-house, check the company’s catalog to ensure it carries the styles and products needed for your window project. You’ll also have more freedom to customize components, though you’ll be limited to that company’s products only. Some companies may work exclusively with a brand, while others stock various options.
Some companies also offer discounts or specials if you’re upgrading many windows. However, you’ll be limited to the in-stock options and be unable to customize. Check the windows’ functionality, appearance, and feel to help you select the right ones for your home.
Which Window Types Should You Install?
Below are the types of windows professional window installation companies offer and their average installation costs.*
- Awning windows ($600–$2,500): These windows use hinges at the frame’s top and swing outward from the bottom. They often employ a crank or a type of glide hardware.
- Basement hoppers ($500–$2,650): These are small windows that run across the top of basements and increase natural light and airflow. They’re often hinged at the bottom to open at the top.
- Bay and bow windows ($500–$2,200): These windows curve outward from your home. Adding a box seat or ledge underneath them can transform the area into a bookshelf or additional seating. Bay windows are angular, and bow windows are more curved.
- Casement windows ($400–$2,400): This window uses a side hinge and swings open to the left or right via a crank. You usually use casement windows in hard-to-reach areas, such as over a kitchen sink or in a bathroom.
- Double-hung windows ($400–$2,000): Double-hung windows are one of the most common window styles. These windows use two locks and open at the top and bottom.
- Garden windows ($600–$2,325): Garden windows protrude from your home to create a space to grow plants and herbs. We recommend them as kitchen windows.
- Glass block windows ($400–$2,200): These privacy windows are translucent yet thick blocks of glass. They allow light into the room but obscure the view, which makes them popular for bathrooms and basements.
- Picture windows ($300–$2,000): These windows act as floor-to-ceiling accents. They provide lots of natural light but you can’t open them.
- Shaped windows ($500–$2,400): Sometimes called geometric windows, shaped windows act as an accent that lets light in where standard windows might not work. Popular shapes include half-round, round, eclipse, triangles, and trapezoids.
- Single-hung windows ($400–$2,000): These popular windows function similarly to double-hung windows but have one center lock. They also tend to be smaller than double-hung windows.

Should You Replace All of Your Windows at Once?
We recommend replacing all of your windows at once if you need multiple windows replaced or if you are upgrading to more energy-efficient windows. This can help save money and maintain a uniform appearance throughout your home.
Can You Install Windows Yourself?
You may be able to save money by installing windows yourself if you have the experience and equipment to do the job properly. See our video below on how.
In most cases, though, we don’t recommend DIY window installation. One reason is that the investment into the right tools may cost you more than you’d pay for professional installation if you don’t already have them. The main reason, however, is that window installation can be dangerous, especially if the window is heavy or above the ground floor. Professional installation removes your risk, ensures the job gets done correctly, and guarantees you won’t void your warranty coverage, as some window manufacturers won’t accept claims if you did the installation yourself.
How Do I Find a Window Installer Near Me?
Most of the companies in our review are national window brands that provide installation services. They either have an in-house team of installers or a network of contractors trained to install their products. Many of the brands have varied availability in different regions, so it’s crucial to find the right local window installer in your area. Use the tool below to find installers that serve your ZIP code.

Is New Window Installation Worth It?
According to the Department of Energy, heat gain and loss through windows are responsible for 25%–30% of heating and cooling energy use. That means heat coming through your windows in summer and out in winter contributes to nearly a third of how much money you’re paying on your electric bills and how hard your HVAC system is working. Upgrading to energy-efficient windows lowers costs by 15% in older homes and more than 24% in newer homes. We see installing new windows as a worthwhile investment because of how much money you stand to save over time in energy costs.
We most recommend Renewal by Andersen for the job. Its in-house installation team means you won’t have to deal with any third parties. You’ll order your windows and have them installed by the same company. Renewal by Andersen is also known for its energy performance and does an in-home demonstration of how its glass blocks heat transference in every consultation.
Before deciding which company to go with, we suggest carefully reviewing warranty terms, customer reviews, and efficiency ratings. We strongly encourage getting a free quote from at least a few companies to compare pricing for the window style and material you’re interested in.
FAQ About Window Installation Companies
What is the most popular window style?
Double-hung windows are the most popular window style because they’re affordable and have a simple, easy-to-use design. Double-hung windows have sashes at the top and bottom that open, allowing maximum airflow. These windows can also tilt in, providing easy access for cleaning.
What is the average cost of window replacement?
We estimated that the average window replacement costs $200 to $1,800 per window including labor. This doesn’t account for additional factors such as window size, frame material, and customizations.
How do I get an estimate for window installation?
Most window installers offer free quotes if you call their toll-free number or fill out a form on the company’s website. After that, you’ll meet with a company representative in person or virtually to review the details of your project and create a quote. Some window installers also offer in-person and virtual showrooms so you can browse the window selections up close.
