I had them install a drip edge and extend a downspout over the overhang on my front porch. The gentlemen that came for my quote were very friendly and seemed knowledgeable. While their quote was high compared to some that I had gotten, I choose them because they seemed the most professional.
They did the work in a reasonable amount of time, but I had noticed a couple issues afterwards.
1) The downspout extension they installed was a slightly different colour than the rest of the downspout. Not a HUGE deal...but they also didn't secure it to the eavestrough and the first big wind almost blew it off.
2) They were also hired to caulk the corners of the eavestrough as we had some leaking. Well, the one corner kept leaking and dripping loudly onto the eavestrough below.
Getting them to come back and fix the errors was quite painful. It took a couple weeks of daily phone calls to get them to even get back to me. Finally they came back and secured the loose downspout and re-caulked the leaking corner. Next rainfall I heard the dripping again. After that they never got back to me after 3+ phone calls and I finally gave up and fixed it myself. Would not recommend them.
