We are extremely happy to recommend Coastal Trim and Design to anyone looking to remodel or enhance their basement or any part of their home. Based on our needs and budget, we chose to go with Coastal Trim and David Krotz, Owner as he was very attentive and detailed to our specifications. Coastal Trim and their staff exceeded our expectations in their professionalism and workmanship. We had half our basement finished and the other half remodeled with a wet bar and the addition of a full bathroom. Thank you David and Coastal Trim. We will definitely use your services again for future needs!

Coastal Trim and Design LLC completed carpentry work on my kitchen island in preparation for it to be painted. They refaced the island and it looks like a beautiful piece of furniture, so much nicer than I ever expected. Dave was very responsive and he and his crew were on-time and ready to work when they arrived and always left the area spotless when they left. The project went as planned without a hitch and I can honestly say they were awesome!
Travis Day
I had trouble finding the right guy for the job, a couple people came by to price what I wanted but I could tell they didn’t really get what I was after and I didn’t have much confidence so I kept looking. Not the case with David, super easy to work with and a true craftsman. The trim and ceiling work turned out better than we could have expected, it’s just awesome. Very highly recommended.
Susan Lisuzzo
David and his team helped my dad get his house ready for sale when he was ready to move into independent living. My parents had owned the house for 50 years and there were quite a few upgrades that were needed. David helped us focus on the things that mattered most for resale. I highly recommend Coastal Trim and Design!

The Coastal Trim and Design staff, under the direct supervision of David Krotz, completed a second level addition to my house in Gaithersburg that was excellent, completed carefully, with minimum disruption and a timely manner. David’s hallmark is his respect for his customers and more importantly the dignity with which he treats his labor force which is in turn motivated and dedicated to performing the work efficiently and competently.

Dave and his crew did a great job on my deck ! They had to rip out all the deck boards and re place with trex and it looks great ! Look at the pics before and after. I would highly recommend Coastal Trim and Design. Stephen Stowell.

We recently had interior work done on our older home in Carroll County, MD. We chose Coastal Trim Design for the job. Our experience from start to finish was excellent. Dave Krotz, owner of Coastal Trim Design delivered on every aspect of his promise and the project. Special attention was given to punctuality, expert craftsmanship, eye for detail, respectful and courteous service. We would strongly recommend this five-star company to anyone who has been searching for the good old days when hard work and integrity between contractor and customer meant something. Respectfully, Ron and Brenda Carlton Sykesville, MD
Valerie Vinson
Dave did an amazing job renovating our basement. He took our vision and ran, creating a great space for entertainment beyond our expectations! Aside from the phenomenal craftsmanship, Dave is extremely prompt in communication, fair with pricing, timely with his work, and flexible with changes that we made along the way- these are hard qualities to find in a contractor! Highly recommend!!
