"I used H&F exteriors to install windows in a 130 year-old historic property. The old windows were crusty and inefficient. The new windows are great, and have cut the heating and cooling bills in half. H&F and their team were terrific to work with, honest and responsive."

"The installers were great. The salesperson made promises that he did not keep and he missed a window. When the person came to measure he also didn’t catch that I was having all my windows done except one. The windows look great. The response when I notified the co that one window was missed was very fast but added to my cost."

".Bob, the owner of Mr. Handyman of Metro East, was right on time to estimate the job. When I contracted with them they set a date to try to accomplish the work but could not accomplish on the first visit (had to go higher on the side of the house). During the initial work they discovered additional leaking that would take some equipment he did not bring, So they finished what they could and rescheduled for the next week to complete the job. The office always kept me informed as to times they would arrive,
The second visit went very well. The leaks did not go all the way to the top windows. They replaced some damaged plywood backing and corner 2x4, applied Tveck, taped around the windows, replaced the siding, and then moved a downspout (connecting it to a recently installed drain line under a new sidewalk).
The next day it rained quite heavily and I got no leaks into the walkout basement. They even made a followup call on Monday to see if I had had any problems.
