Replacement windows are one of the most important investments that you can make as a homeowner. New windows can increase your home’s energy efficiency, potentially reduce your utility bills, and could increase your home’s value significantly.

Replacement windows, however, are no small investment. Before you sign a contract for new windows, it’s important to ask the right questions. The following five questions can help you vet potential window dealers and installers and choose the right professional for your home improvement project.

#1. Is Your Window & Installation Warrantied?

All reputable replacement window dealers and installers should warranty their product and their work when installing new windows. The strength of the dealer’s and installer’s warranty are good indications of their confidence in their product and craftsmanship. Expect your window dealer and installer to have a warranty. The better the warranty, the more impressed you can expect to be with the installer’s work.

#2. Can I Call Your Window Installation References?

A replacement window dealer and installer with no references raises significant red flags. Every installer you hire, especially for an investment as important as window installation, should have multiple references from previously satisfied customers. When calling references, ask them questions such as:

  • When did you hire this installer?
  • Would you hire this installer again?
  • Would you refer this installer to others?
  • What challenges did your installer encounter on the job, and how did they handle those challenges?
  • What did this installer do very well?
  • Did your project come in at or under budget? If not, why not?

Asking these important questions can give you a clear picture of how the replacement window installer you’d like to hire performs on the job, and ultimately, may give you an idea of how your job will proceed.

#3. When Can You Install My Windows?

Good quality replacement window installers are often in high demand and booked out a few weeks. The right window installer is worth waiting for, so be prepared. If you’re on a tight timeline, get started early to ensure that your windows will be in place when you need them.

#4. What Are the Window Frame Materials?

Most replacement window dealers focus their sales pitch on the window glass. While insulated glass is certainly a very important factor in the window’s energy performance, don’t neglect to ask about the window frame material. After all, while replacement windows are mostly glass, it has to be held securely in a frame in your home. And, it’s the frame that provides the operation of the window. You don’t want to invest in new replacement windows only to find that they leak air and moisture or are difficult to open and close.
