Great experience with excellent communication. Rooftop deck powerwashed and stained. The staining exceeded expectations and is working great. A shade sail was also installed and it is high quality and installed very well. Recommended.

Ryan and his team did a fantastic job with cleaning and staining our deck. It was getting pretty old looking and gray from the sun, but it looks brand new now. This was a big job because it's a two-story deck, but they gave a fair price and took care of it in just a few days. Very professional and courteous service from start to finish. Would highly recommend them.

We hired Black Diamond to power wash and refinish our deck after a recommendation from a super nice Home Depot employee, and it was a great rec! Ryan and crew were super responsive, professional, and thorough and our deck looks great. Even better, it'll look great for years to come! Thanks guys!

Black Diamond Power Washing was great! They stained my rooftop deck and that of my next door neighbor. They kept everything clean and protected, including my newly installed fabric awning. I highly recommend this company! Be sure to book in advance as they are highly sought after!

We needed our patio cleaned before summer and contacted Black Diamond for a quote. They were responsible, punctual, and did an amazing job! We even asked them to remove some excess water after they finished and they did which we really appreciated. We would recommend them and plan to use them for future pressure washing needs.

Ryan and his crew did an amazing job on our deck. The process was seamless and Ryan was extremely responsive from beginning to end. Can't recommend them enough to anyone who is looking to have their deck refinished.

My husband and i purchased our home a year ago and the deck desperately needed washing and staining, and we are so thrilled with the results from Ryan and his team! From the first email Ryan was prompt, professional, and made us very comfortable and aware of the process. The deck looks so great and we know it is a good investment to maintain the wood for years to come. I would recommend Black Diamond to anyone in the Baltimore area looking to get their deck looking fantastic!

Ryan and his team did an amazing job with our multi-level, complex deck! They power washed, sanded, and stained everything beautifully while protecting everything that shouldn't be stained. Ryan was very responsive, professional, and easy to work with. Highly recommend!

We recently used Black Diamond Power Washing to power wash and stain our rooftop deck in Locust Point. Ryan was very responsive to our inquiry, and even was able to fit us in earlier in his schedule than expected. His team was very friendly and efficient in the two day process, and we couldn't be happier with the results. I would recommend this company to anyone looking for great services and to support a local business!

Ryan, John, and the whole crew were amazing. They power washed 2 decks and our brick patio in a day. Then they came back a second day to apply stain to the decks. The end result looks amazing - well worth the money and I'm grateful I didn't attempt this myself after seeing how much time they spent on every detail (railings, supports, nooks and crannies, etc). These photos show what it looked like before they started, then after power-washing, then after staining for each area. We can't wait to spend the summer outdoors.

Had a great experience! Response was fast, the estimate was fair, and the communication was good with easy scheduling. They worked with us to get what needed done and worked quickly, plus we ended up with a great final product that we're super happy with! Would def recommend and will use again when needed. (We had a large roof deck and smaller 2nd floor back deck both power washed and stained).

Overall great experience and service! They did a virtual quote, if you want to limit people in your house. They were on time and worked long hours to get the job done in a few days. They were very respectful of our home and wore masks when they were bringing things up and out of the house. I’m sure our pergola was time intensive with all of the beams but, the quality of work across the whole deck was great!
