The Soft Washing Experts

Soft Washing Techniques to safely clean your home or business

  • Our soft wash technique prevents water from getting behind siding or damaging its delicate surfaces.
  • The soft wash method is safe (and efficient) for cleaning vinyl siding, stucco and bricks.
  • The pressure is as soft as your shower.
  • Combined with our specially formulated detergent, the job will get done right!

Our Roof Cleaning process is gentle and safe, while strong enough to remove moss, algae (black stains), and environmental dirt without damaging your roof.

  • We never use high pressure water on the roof, but our softwash process makes it look new again!
  • The black streaks are gone the same day and the moss and lichens are killed in the process.

Bogdan and his team are top notch. Professional, friendly, and efficient. The estimate is what the job cost. No surprises! Accommodating with my schedule and on time. Highly recommend BLK Diamond!

Bogdan arrived on time, was polite, very professional, thorough and efficient. He was determined to help with every single spot on our windows and our house has never looked better.
