What Our Clients Are Saying About Us

We had a great experience with coastal Chimney Sweeps! Dean solved a persistent issue with our pellet stove that others couldn't figure out. They were knowledgeable, efficient, and explained everything clearly. Now, everything works perfectly and we finally have our heat back. Highly recommend them and we will absolutely be using this company going forward!

Working with Dean has been a pleasure. He was quick to come out for a quote, provide a quote that day while onsite and talked me through what he was going to do. He shows up when he says he will, he is very thorough with attention to detail, and the job site when he leaves never looks like he was there except an amazing looking chimney! I would highly recommend Coast Chimney Sweeps to anyone.

Fast, efficient, and incredibly meticulous! I had several quotes on our chimney for repairs and to add a cap - Dean provided fast, reliable service and was very trustworthy with his quote and recommendations. I highly recommend Coastal Chimney Sweeps - he will be the first I call every time!

You usually don't get all three when it comes to price speed and quality. I was thrilled with how attentive and great the work done on my chimney was. Most companies were scheduling out months just to take a look. They were able to come out same day I reached out give me a quote and quickly move forward. Highly recommend!
