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."

"Al was fantastic! He clearly explained that my fireplace was shutting off as a safety feature due to low oxygen levels. He also reassembled the logs in the firebox and showed me the proper way to start and stop the fireplace. Highly recommend his service!"

"Omar and Victor did an excellent job. They inspected and cleaned the chimney and installed the new stove. Work was efficient and effective. They cleaned up after themselves and were extremely pleasant to spend the time with. I thank them for their good work. Whitney Schofield"

"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."

"The chimney liner was replaced and extended in accordance with safety regulations, ensuring compliance and durability—very good job, and I highly recommend this service!"

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

"We hired Josh to completely transform our fireplace area and couldn’t be happier with the results. From the initial inspection to the final install, everything was explained clearly and handled professionally. The stonework and stove setup came out absolutely beautiful and completely changed the feel of the room. Josh was clean, punctual, and took real pride in his work. The before and after difference is night and day. I’d highly recommend him to anyone looking for quality chimney or stove work done right."

"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."
