You need to be careful about selecting the right windows, but you also need to be careful selecting an installer. We’ve received a disturbing number of complaints from consumers regarding window installation work. Even more alarming is that a large percentage of the complaints were about incredibly sloppy work.

The ratings of local window installers shown on our Ratings Tables can help you avoid many of these problems. We surveyed area consumers (primarily Checkbook and Consumer Reports subscribers) for their ratings of window installation outfits they had used. Our Ratings Tables show the results of our survey for the companies that received 10 or more ratings. The tables report the percent of each company’s surveyed customers who rated it “superior” (as opposed to “inferior” or “adequate”) for our survey questions “doing work properly,” “starting and completing work promptly,” “letting you know cost early,” “advice on service options and costs,” and “overall performance.” Our Ratings Tables also report the percent of surveyed customers who rated each company “adequate” or “superior” (as opposed to “inferior”) for “overall performance.” (Click here for more information on our survey and other research methods.)

In addition to ratings from customers, our Ratings Tables show counts of complaints we gathered from the Better Business Bureau (BBB) for a recent three-year period and complaint rates relative to the volume of work companies do.
