Finding Several Contractors
Start out by getting several bids on your project. They're free and you'll be amazed how much information you can gleam from the different companies. We suggest getting anywhere from 3 to 5 bids (by the 5th one you'll be a pro). Here are several approaches to finding good quality contractors. Google has great local listings so type in "Phoenix replacement windows" and check out the local listings at the top (but below the paid or sponsored listings). These are all local companies - we suggest you contact the companies that have the most number and highest rated reviews. You can also use a service like Angie's List that shows local companies and provides in depth reviews. There is a yearly cost to access the companies so it may only be worth it if you have several projects that need professional contractors.
