Frequently Asked Questions

What does the window and door installation process involve?

The entire process typically includes an initial consultation, product selection, custom window measurement and manufacturing if needed, scheduling the installation date, the actual window and door installation, post-installation inspection, paperwork, and clean up. A good company will guide you through every step.

How long does it take to replace windows?

For a whole home window replacement, the installation itself usually takes 2-3 days depending on the number of the windows replaced. Total time from order to installation may range from 2 weeks for standard sizes to 6+ weeks if custom manufacturing is required. The project manager can give you an estimated timeline.

Why should I replace my old windows?

Old, outdated windows are likely not energy efficient. New window technology helps lower energy bills by preventing air leaks and heat transfer. Replacing old windows also improves appearance, comfort and can add value to your home.

How much does it cost to replace a window?

The average price to replace a single window is $500-$1200 including labor, but costs can vary widely based on size, materials, accessibility, customization and other factors. Get quotes from multiple window companies to find the best value.

What is the best way to find good window repair services?

Quality window companies like the ones we recommend typically have repair technicians available. You want to find an experienced professional to properly diagnose and fix window issues. Companies that offer window warranties often provide repair services too.

Who is responsible for window replacement after installation?

The window company should assume responsibility for addressing any installation defects or issues under their workmanship warranty, usually 1-5 years. The manufacturer’s warranty would cover any manufacturing defects like seal failure or glass breakage.

How do I know if a window company is reputable?

The best window companies have excellent ratings and reviews. Check third-party sites like the Better Business Bureau for complaints. A long history serving the area, certified installers and strong warranties also indicate a reputable provider.
