Factors To Consider When Choosing A Window Installation Company

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

Certifications and Insurance

All windows installation companies should have proper certifications and licenses 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. 

Also, ensure your windows installer has insurance to cover its workers and protect you from liability. Windows installation companies should have liability coverage and workers’ compensation.

If you work with an independent windows installer, check that the company is certified to install your selected window brands. Many windows manufacturers maintain a network of certified installers to install their products. This ensures the windows are installed to the company’s specifications and instructions. Some installers may be qualified to install windows but not have brand-specific certifications. We recommend using an installer from within your window brand’s certified network instead of a general windows contractor when possible.  

Reviews

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 that have completed windows projects to get a feel for their experiences with their selected installer. 

Warranties

Window replacement is a sizable investment, so you’ll want to make sure your new windows are insured for repairs, manufacturer issues, and necessary replacements. Windows warranties include varying coverage for the glass, window frame, and other components. You may receive a separate manufacturer’s warranty and a labor warranty if your windows manufacturer and installation company are different.

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 product catalog to ensure it carries the styles and products needed for your windows project. You’ll also have more freedom to customize components, though you’ll be limited to that company’s products only. 

If your chosen installer doesn’t manufacture its own windows, it will offer a selection of local and national window brands. Some companies may work exclusively with a brand, while others stock various options. Some companies also offer discounts or specials if you’re upgrading a large number of windows. However, you’ll be limited to the in-stock options and won’t be able to customize.

We recommend taking advantage of any in-person or virtual showrooms, in-home consultations,  and demo window displays that your installation company offers. Check the windows’ functionality, appearance, and feel to help you select the right ones for your home.

 


 

Finding a Local Window Installer

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.

 


 

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 reduce your overall window replacement cost. 

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.
