Why BD
You get Gabe and Connor. Not a crew you have never met.
We started Black Diamond because we kept hearing the same complaint. Companies send whoever is available that day. With us, the co-owners show up to every job. That is not a sales line, it is just how we operate.
What customers say
Straight from Google.
"I'd highly recommend Black Diamond Pressure Washing. Gabe and Connor were professional, efficient, and incredibly easy to work with. The clarity of their initial proposal and the final outcome were perfectly aligned. Zero gap between what was promised and what was delivered. What impressed me most was the level of care and attention they showed; it clearly felt personal to them. When they left, you wouldn't have known they were even there, other than how clean the houses looked. I really appreciated the thoroughness and will definitely be using them again."

Google Review
"I found Black Diamond through a few friends that had work done in the past and they had loved it. Getting in contact with Connor and Gabe was extremely easy. Once they were able to come down and check the property you could see the pride and care they take into their work with every detail, down to the professionalism and time taken into their quote. Giving us honest pricing and reasoning with said pricing. The house has never looked as good as it does now and we couldn't be happier. I will definitely be referring all of our friends and utilizing the service myself in the future!"
