Black Diamond Seal Coating

I would highly recommend Black Diamond Sealcoating. Owner Jeff Feltner was prompt, professional and very good a communicating. He submitted a bid and appropriate paperwork quickly. There were some delays in completing the job due to the need to work with another contractor. Jeff kept me informed and did a little “nudging” to get the additional work completed. His prep work on the surface was extensive and the finished job very professional.

Jeff and his team did a great job of prepping, including scrubbing off the moss, and then put a beautiful sealcoat on. No overspray, clean edges, solid consistent coverage, and no hassles. The result is top-notch and really adds class to the property.

Street seal coating experience with Black Diamond was great! They were easy to work with from start to finish and the whole process went smoothly. Would absolutely hire again.

It went great. They showed up on the morning they said and did an outstanding job, paying close attention detail. Jeff’s price was fair and I’ll be using him again in a few years.

Jeff and crew did our job on the cusp of the rainy season. We really appreciated their professionalism, doing what they said they would do when they said they would do it. Very good communication skills with us and the renters at the job location. Many people have said the job results are excellent. thanks

They did a fantastic job and were easy to work with.

"Awesome work!" I have been a Property Manager for 30+ years here in the PDX area, and I have had the opportunity to utilize a number of other companies in the past for my seal coating maintenance needs. We needed to have two of our properties asphalt areas sealed, and choose to go with Jeff's bid, as it was very precise and accurate! "I Highly Recommend, Black Diamond Sealcoating!! Jeff and his crew were very punctual, professional, and highly knowledgeable. They had no problem working with us closely on both projects, and did a great job in prepping, and cleaning prior to the actual application. After they were finished, they left both properties looking perfect, and "Professionally Done!" "I won't hesitate calling them for any of or future pavement, or striping needs!"

Excellent. Jeff informed us of the work to be done and the expected timeline. All was completed within the time line and with EXCELLENT results. We are very pleased with the work!
