18 years ago I had all new eaves, fascia, soffits, window trim and other aluminum trim put on the house. The colour was a light beige but over the past 15 - 16 years, black stains (dirt and mold?) began to develop everywhere. Some areas where there was more shade were worse than other areas. I checked online reviews and hired Maple Window and Eaves Cleaning after a few emails back and forth with Yitzie, the owner who provided an estimate after I sent some photos of the house exterior. I could have done the window exterior myself but decided to have Yitzie's crew do that as well for the added fair cost. His crew of three, Narase, Daniel and Chris arrived on time and in addition to doing a great job (cleaning the interior of all eaves and downspouts, cleaning the exterior of ALL beige aluminum, cleaning of window exterior), they were all so kind, easy going and professional. The following is MY FAULT. Most of the exterior beige aluminum came out about 70-80% cleaner than before with the remainder coming out like new. Now, had I called to have the exterior cleaned every 2 - 3 years since newly installed, all stains would have likely come out. I noticed the stains beginning about 2 - 3 years after being newly installed and I ignored the stains which just continued to get worse for the past 15 - 16 years. I only wish I hired Maple Window and Eaves Cleaning much sooner. Highly recommended! I included before and after photos.
