5/5

They did fantastic work at my home. The setup was difficult, I'm sure: my home is three stories, and on two of the sides the driveway/walkways are sloped, making it a hard sell for ladders. Also, the contractors who built my home left stickers on the windows as well as paint overspray. It wasn't pretty. Regardless of all that, Bogdan and the rest of the team did a fantastic job cleaning every single window. All the stickers were removed (with no trace of leftover adhesive) and the overspray is gone. Everything is pristine. I will certainly be calling them again.

Roof Cleaning

Amazing aesthetic results are not the only reason to have your roof cleaned. The dark stains typically seen on the north face of roofs are a cyanobacteria that retains moisture, allowing moss, lichen, mold and fungus to grow and flourish. This bacteria feeds on the limestone filler in asphalt shingles. Moss and lichen break down the granular surface which is designed to protect asphalt shingles, shortening the service life of your roof

Roof Cleaning South King County WA

If you have moss on your roof, as many of us do in the NW, use BLK Diamond Exterior roof cleaning service.  Bogdan did an excellent job ridding my roof of moss and also protecting my trees and shrubs from any residual chemicals. It’s very clear that Bogdan at BLK Diamond takes pride in doing a job well done. Thank you!

Gutter Cleaning South King County WA​

We hired BLK Dimaond Exteriror Solutions a few weeks ago for gutter cleaning, Bogdan showed up in a few hours to give us an estimate and explained what he was going to do. We told him we had a leaking issue with one of the corners of the gutters and he caulked it for us to prevent future leaks, would definitely hire again.
