The two men came in and went right to work cleaning my windows they did this very rapidly and the windows and screens were clean. They left no mess and were very polite.

Came early, we're quick, quiet, and friendly. Condo was small job for them, so was at minimum charge. They did two skylights that I had never thought to request. Will use again.

Steve and his assistant did a GREAT job cleaning my windows. The office staff is very pleasant to work with over the phone. The only reason I gave them a 4.5 instead of a 5 is that they did not come during the promised two-hour window. I had to call in 20 minutes past the window to find out what was going on rather than getting a call from them saying they would be late. The work was a definite 5.0.

Did not wash all of house. Completely ignored the sun room and not much done on West side of house. What they did was fine, they just didn't do the whole house.

They did a good job cleaning the windows but did not clean between the windows and screen sills, for $410 for 20 windows I expected them to do that for that much money.

They did a good job but they charged me 199.00 to do a 45 minute job. Way to expensive to clean out the gutters on my house.

Just wanted to say thank you for doing a great job!! You really did help this veteran out with price as well. Cannot not say thank you enough for everything. Hundred percent satisfied. You bring your own ladders, and snake the down spouts, as well as not leaving a mess. Sincerely, Happy Veteran!
