My wife was approached by Power (roofing) sales at BJ's Wholesale Club. We live in an old house with very old windows and roof. We always seek 3 estimates for any job, but it never happened in our case, even though we attempted twice: Power had two folks show up one evening who went into our attic and discovered the leak we already knew was there but hadn't told them. They left us with an estimate 2+ hours later with of course a "discounted quote" if we signed up with them, pledging we wouldn't seek estimates from competitors. (We did that, knowing we could cancel the agreement in 3 business days). Well, we did cancel when I really wanted two other quotes from Power's competitors. But before the others (with smaller staffs) could show up to give an estimate, Power was back out to receive our signed cancellation--and talked us into their "lowest estimate possible" for the roofing job (with one free window-replacement thrown in). Long story short, with winter fast approaching we did go with Power and were satisfied with the work...but, down deep, we know that we could've had lower estimates. [On the other hand, we can pay it off over several years with the financing they have in cooperation with a national bank. Because the one new window was installed 5+ weeks later, our first payment is requested a good two months after the roofing job (with no down-payment). Guess we'll never know if the other companies would've offered similar financing...] We will talk up Power Home Remodeling with our neighbors who have similar-age houses, saying further good things about Power if they follow up with good customer-service now that the window replacement is done. If good customer-service is absent, then I wouldn't recommend an overall satisfaction rating...
