What Factors Are Important To Consider When Choosing a Window Installation Company?

Here are the key factors to consider when searching for a windows installation company.

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.
Read online reviews from the Better Business Bureau, 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 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.
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.
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.

Types of Windows

Below are the types of windows professional window installation companies offer and their average installation costs.*

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.

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.

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.

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 are one of the most common window styles. These windows use two locks and open at the top and bottom.

Garden windows protrude from your home to create a space to grow plants and herbs. We recommend them as kitchen windows.

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.

These windows act as floor-to-ceiling accents. They provide lots of natural light but you can’t open them.

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.

These popular windows function similarly to double-hung windows but have one center lock. They also tend to be smaller than double-hung windows.

Our Conclusion

The right installation company will make your windows replacement project seamless. National window brands with installation services offer a one-stop-shop approach, providing a network of installers trained to install their products. Independent windows installers can offer a more extensive catalog of brands, giving you more customization options. Look for special promotions and discounts that can make your window replacement affordable

We recommend getting quotes from at least three window installers to find the best catalog and pricing. Compare the available window styles, materials, energy efficiency offerings, and warranty details.


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.
