TNZ Windows and Eaves' service was great. They provided a very reasonable quote for cleaning my exterior windows, were helpful and informed when I called, and went out of their way to accommodate a request. The concern I had was about birds hitting clean windows since they can't see glass. TNZ said that they don't sell the bird-protective window stickers, but if I bought some, they would put them up for me. Since I needed only 6 stickers, they did it at no additional cost. They were right on time, scraped and washed my windows in a quick, efficient, and effective manner using gentle materials. And they cleaned all my screens too - included in the price. I should state here that my windows were really dirty and hadn't been cleaned in about 3 years. I will hire them again - the only reason it's not 10* is there were a few small marks on a couple of windows.
Since they do eavestrough cleaning and repair and downspout disconnection, I will also try their other services.
