Get matched with top fireplace pros in Derry, NH

"I am very pleased with the finished project and quality of work Sean provided. The chimney was leaking during rainstorms. Sean has replaced the chimney cap and sealed the exterior bricks. The chimney no longer leaks. We are so pleased with this outcome, we have Sean scheduled to do an extensive build-out of an existing fireplace for a pellet stove insert. I would recommend Sean for any masonry project. He provides quality work, is great with quick responses, and always on time."

"Steve did Great work and had the fireplace working great!"

"I had birds chirping in my fireplace. Mcbriens safely removed the birds and nest and installed an animal guard to prevent future critters! Thank you guys so much."

"Josh arrived fully prepared to clean my gas fireplace and chimney. He explained everything clearly, was meticulous about cleanliness, and solved an unexpected issue with ease. He relit the pilot light and explained everything to me as he went along. Based on Josh’s work, I can highly recommend Ashguard to care for your fireplace."

"Duran removed my old gas fireplace, ran a new 6-inch insulated liner down the chimney, (which was not easy, the flue needed to be opened up a bit in certain spots). He rebuilt and repointed my upper chimney, waterproofed it, and installed an amazing new wood burning fireplace, that we are loving! He came out to the house, estimated the job for free. His price was thousands less than the competitors (others charged $250 just to come out and estimate) Duran was professional, honest, clean, hardworking and affordable. If you're getting chimney work done, you are crazy if you don't call this guy. I highly recommend. R"

"Travis was very thorough and courteous. He explained the sequence in restarting the gas fireplace."

"The grind and repoint work completely changed the condition of our chimney. The deteriorated mortar was properly removed and rebuilt, leaving clean, solid joints and a uniform finish from top to bottom. The process was thorough and never rushed, and it was clear the focus was on long-term durability rather than a quick cosmetic fix. Everything was explained clearly, the site was left clean, and the chimney now feels secure and weather-ready going forward. Very happy with the outcome.Highly recommend!!"

"Sean and Alan were good. They pointed and flashed the chimney the same day and left."

"Jim called back within a day of me requesting an estimate and came by a couple of days later and followed up with a written estimate by email. He knew immediately what had caused my front steps to fail. He started the work in a week or so. I was please that he offered me some choices and what would cost more or less. He was able to use most of the existing brick and stone. He updated me each day on how the project was going. Jim was great to work with and did a fabulous job. I would recommend Celtic Masonry without reservation."

"Was here when He said he would be, which is not the norm now a days ! Patch job where a stove pipe came thru the foundation came out good."
