When I bought my 100+ year old house in West Roxbury, the double-hung windows were the most awful replacement windows imaginable. Not only were they ugly as sin, they were barely functional. Some of them wouldn't close completely, some of them wouldn't open at all, and some of the sashes were crooked. Jeff came out to measure the windows and make recommendations. I replaced all of the double-hung windows with Anderson (wood inside, no-maintenance outside) and other windows with Marvin awning models, as Jeff recommended. He spent a great deal of time with me discussion the options, and then patiently helping me decide on details, such as number of divided lights. The exterior window frames and sills had been clad in aluminum or vinyl, and Jeff explained that there could be water damage underneath. They replace these if necessary with MDF (I believe) on a board-by-board basis, for a reasonable price. After I placed the order, Dennis took over for scheduling and invoicing, and arranging for the building permit. There was a delay of several months because they were booked well in advance. As it turned out, the Anderson windows came in a bit earlier than expected and there was a break in their schedule, so those were done first. The guys who did the work were professional and pleasant, with good communication skills. They cleaned up completely at the end of each day. I had been focusing on function, eagerly anticipating having windows that actually worked, and I was stunned by how beautiful the windows are, and how much better the house looks from the inside and outside. Another unexpected benefit is that the screens are much less visible than what I was used to. The guys did a great job on the frames and sills that they replaced. After the double-hung windows were in, I decided to replace the 3 double-hung windows in the garage, so placed another order. By the time the Marvin windows came in, COVID infection rates had increased to the point that I was concerned about having anyone in the house. Dennis could not have been nicer about waiting to install them until I was ready. The job was completely quickly after I gave them the go-ahead. It's been about 6 months since the job was finished (I should have done this review long ago) and the windows function beautifully. I give Fisher Windows my highest recommendation.
