We used to rehab the mechanics of some of our windows. We love the look of the old windows, but they were very tough to open and close and they were drafty. After the ropes were replaced with chains and they were made more air tight, the windows work great. I like the look of the copper chains. David came to size up the job initially and he did the work along with another worker, and they were professional and pleasant to have in the house. I thought their price was reasonable and we’re very pleased with the work.
