Top Questions to Ask Before Hiring a Window and Door Contractor
Replacing your windows or doors is a big investment—and choosing the right installer is just as important as choosing the right product. A good installer can make your home more comfortable, energy-efficient, and secure. The wrong one can cost you time, money, and peace of mind.
Before signing on the dotted line, here are the top questions you should ask any window and door installer to ensure you’re making the right choice:
- Are You Licensed and Insured?
Make sure your contractor has the proper licensing required in your state and carries both liability insurance and workers’ compensation. This protects you in case of property damage or injuries during installation. - How Long Have You Been in Business?
Experience matters. A company that’s been around for many years likely has a track record of satisfied customers—and the expertise to handle your project efficiently. - Do You Offer a Warranty on Products and Labor?
Reputable contractors will back their work with a labor warranty in addition to the manufacturer’s warranty on the windows or doors. Ask how long the warranty lasts and what it covers. Is there an extended warranty available? - Can You Provide References or Reviews?
Look for online reviews and ask for recent references. A reliable contractor should have no problem sharing customer testimonials or pointing you to projects they’ve completed nearby. - Who Will Be Doing the Installation?
Is the work done by installers that have been properly trained and certified by the manufacturer or third party organizations such as Installation Masters? - What Brands and Materials Do You Work With?
A knowledgeable contractor should be able to explain the pros and cons of different window and door materials (vinyl, wood, fiberglass, etc.) and help you choose the best option for your home and budget. - What Is the Project Timeline?
Ask when the work can begin, how long it will take, and what might cause delays. It’s important to have realistic expectations and know how the company handles scheduling. - What Is Included in the Estimate?
Request a detailed written estimate that breaks down the sizes, colors and specifications of the windows and doors being quoted. Does the quote include labor, removal of old materials, cleanup, and any possible additional charges? Avoid vague quotes. - Do You Handle Permits and Inspections?
Some cities require building permits or inspections for window and door replacements. A professional contractor should know what’s required in your area and handle the paperwork, or provide guidance. - How Will You Protect My Home During Installation?
From drop cloths and dust control to proper disposal of old windows, your contractor should have a clear plan for protecting your property during the job.
The right contractor will welcome your questions—and give clear, honest answers. Taking the time to do your homework now can save you headaches later and ensure your window or door replacement project goes smoothly.
