Pre-screen aggressively by telephone.
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.
For Quality Windows & Doors, the company slogan, "A Window Company You Can Trust" is more than just a slogan. It is a way of doing business each and every day. Company president Eric Warm adds, "And we will always keeps your property clean."
Those, say Warm, are his company's guiding principles: Trustworthiness and cleanliness. If necessary, you can leave a Quality workers alone in your house without worry. Not only will they perform the work to your complete satisfaction, they will also take extraordinary care to protect your floors, carpet, driveway, and flower beds. You'll find your home –your "domain," as Warm calls it– in exactly the condition you left it. And there is never any smoking anywhere. Not in your home, not on your property, not in the street.
Quality Windows & Doors performs all jobs with utmost attention to detail, even so-called fast replacements: putting new windows and doors over old frames. Though these retrofits are theoretically less difficult, Quality installers perform them as meticulously as higher-end jobs.
It's on those larger projects, however, where Quality Windows & Doors' superior workmanship is most on display.
