You’ll want to "pre-screen" window contractors by phone before you hire them. Though they’ll be asking you questions about your project—location, number and type of windows, timeline—think of this phone call as your fact-finding mission. You want to eliminate candidates who don’t meet your expectations. So answer their questions, but make sure they answer yours as well.
There are many questions you can ask, and many will be dictated by your own specific circumstances. But make sure to ask these five:
• How long have you been in the construction business? • What is your specific experience with window installations?
• Is there a specific window you use or recommend? Why? • Do you have your own installation crew or do you subcontract the work?
• What are your payment terms?
• Are you on site during the installation process?
It’s also a good idea to ask how the company handles problems once the project is complete. They should also be able to provide a list of referrals, preferably in your area. And find out about warranties beyond what the manufacturer offers.
If possible, work with installers who have exclusive relationships with established, name-brand window manufacturers. You won’t want to work with a company that buys from second-hand shops or, even worse, out of someone's trunk. You can save money with cut-rate products, but only in the short run. When they break down, you'll be left with more cost and inconvenience. Suppliers should be reputable and have a fixed address.
