“The repair work they did in Alexandria this summer was good. They did a nice job. They replaced some rotting wood and put in a new gutter. They adjusted it and made both sides of the house match.

She said everything went well when they came out. I would use them again. I would give them an A.”
“An Exterior put a new roof and new gutters on. They did it very quickly—like one day. They were in and out and were very clean.

“We're happy with everything. Everything was good. We had a lot of work done, but I don't have any complaints. They repaired the side of my roof, like some gutter issues—they had been torn off after some storms that we had out here in DC. They were good. They were on time. The quote was very close to what was initially suggested. They came out, did the work, and got out of the way. They cleaned up after themselves when they were done. The quality of the work so far is fine. It wasn't a ton of work, but it's pretty cut and dry. They followed direction well. It came pretty close to the power lines, so we had to deal with the power company. That was a little bit of an extra issue that we had to deal with. But it was good. I'd definitely give them an A.”
