3 Important Questions to Ask a Window Installation Contractor

Hiring a reputable window installation contractor ensures your home’s protection against the elements. This allows you to make the most of your investment and enjoy the many benefits your newly installed windows can bring. To make sure you are working with the right people for this major home improvement project, ask your prospective contractor these key questions during the vetting process:


1. “Are You Licensed or Insured?”

Be sure the window contractor is licensed in the local area they are servicing. Also, verify that they are fully insured to protect you from liability in case anyone is injured on your property during the construction. They should be willing to provide their license number and copies of their workers’ compensation and general liability insurance documents.

2. “Are You Factory-Certified?”

Factory-installed installers are experts when it comes to specific products. Renewal by Andersen® of San Antonio specializes in replacing old windows with high-quality Renewal by Andersen replacement units, from double-hung to bay windows. Working with us gives you the peace of mind of having one-company accountability and a single point of contact for the lifespan of your windows.

3. “What Warranties Do You Offer?”

Ask about the window contractor’s warranty coverage and make sure they show it to you in writing. Most manufacturers offer 10- to 20-year warranties. Read over the warranty carefully and ask your contractor to clarify anything that’s unclear to you.

"If I could heap more praise on Renewal by Andersen, I would have to buy a dump truck. They recently replaced 13 doors in my home in an exemplary fashion. Very professional, efficient and, in my estimation, worth every penny."
