ASPHALT Maintenance In Portland

Black Diamond Sealcoating has the knowledge and experience to handle any size job. We are big enough to get the job done but small enough to provide personal, one-on-one service and that is important.

We pride ourselves in our ability to accommodate any schedule for home and business owners alike. We have flexible hours to ensure we get the job done when it’s convenient for you – we strive to minimize any impact on you or your customers as often as possible.

We use professional equipment to achieve the best possible finished product. In addition we also perform regular pavement maintenance, which can double the life of your asphalt, saving you thousands in replacement costs.

If you’re in need of driveway sealing, parking lot maintenance or line striping, Black Diamond Sealcoating has you covered. We provide residential and commercial clients with affordable, professional asphalt services.

We service the Portland Metro area, Tri-county area, Hood River County and will soon service areas in the state of Washington as well. Our services include: driveway sealcoating, parking lot sealing, hot crack sealing and pavement markings.

CUSTOMER FEEDBACK

“Jeff and the crew at Black Diamond Sealcoating did an amazing job on my extensive driveway. They were on time with their service, very quality oriented, and went above and beyond my expectations. We had an unexpected thunder storm during installation that washed out part of the sealer. They came back and repaired this area ASAP without me even asking about it.”
