How to Choose a Window Contractor

When you’re shopping for new windows, it’s important to look for a company that provides quality products backed by excellent workmanship. To avoid problems with your window installation, here are some suggestions to help you find a reputable, trustworthy contractor.

Ask Friends and Family for Recommendations

Your family, friends, co-workers, or neighbors who have gone through the process of installing new sliding windows may have great suggestions. We recommend starting with three prospective contractors and then whittling down your list from there.


After getting initial suggestions, it’s time to do some online research. Check the background of the contractors you’ve shortlisted. It’s not hard to confirm the license and credentials of any reputable contractor. Certifications are another qualification you should look into. Finally, be sure to check online reviews.

Visit the Contractors

Choose several “finalists” from your list of contractors and visit their shop. You can tell immediately that a contractor is not trustworthy if they won’t give you a proper physical address or if you find one on their website but can’t locate it physically. Good contractors may also have a showroom where you can look at their products in sample applications.

Talk to Them

Get a feel of what it’s like to work with a contractor by talking to them, either personally or on the phone. A reputable contractor should be respectful and polite, and they should also be willing to answer your questions directly and without any vagueness.
