When you’re looking for a window installer, it’s important to choose one who will do the job right and treat your home with care.

Here are some tips for finding a trustworthy contractor for your windows replacement in Naperville:

1) Seek out written estimates from at least three different installers. If there are price variations, ask for an explanation and don’t simply select the lowest bidder. Have the installers itemize their estimates so that you can see exactly what is included in each bid.

2) Verify professional licenses, insurance policies and bonding by calling your state’s licensing board or checking with local building officials or contractors’ associations.

3) Do a background check through Angie’s List, the Better Business Bureau or other agencies in your area on any contractor you’re seriously considering for the project.

4) Determine if the project bid being offered by an installer is an estimate or a fixed price. If it’s an estimate, determine a specific amount by which the price could increase on the job and set a cap; then go ahead and sign up! If not, be sure to write down all details of your agreement in writing before signing anything.
