At one recent customer's home, DNA Masonry & Chimney Services installed a new insulated chimney liner and took on a number of masonry projects tied to old uninsulated thimbles throughout the house. A recent customer said DNA cleaned their chimney and helped make sure the wood-burning stove was properly placed. When unexpected chimney issues came up on one recent job, that customer said they quickly adapted and changed their approach. A recent customer said they kept to their schedule, completed the job within the estimate, left the jobsite clean and handed over warranty information at the end. A recent customer said Dave evaluates the job and clearly explains what needs to be done and why. A 2025 customer said Dave and his crew worked through a cold December to install a difficult chimney lining, came back in spring to finish repointing, and that they could use their wood stove again. A 2025 customer said David diagnosed a chimney problem and replaced the chimney liner. A 2024 customer, whose chimney sweep had found deterioration in the flue, said Dave and his crew replaced cracked bricks and dealt with the flue deterioration in 2 1/2 days on a fixed-price bid. The masonry reaches past the chimney. A 2024 customer said David Mangan repaired cracks and holes in their cellar wall, refaced it with concrete and repaired cracked joints in the stone foundation. A 2024 customer said david and his crew tore down their old chimney and rebuilt a new one, with some excavation into the foundation. A 2022 customer said David and Ethan did a full demolition and rebuild of their chimney and fireplace. A 2026 customer said Dave did a tile hearth for them. A 2022 customer said Dave found unexpected chimney issues during a pellet boiler installation and had them fixed in a day. A recent customer said the service was good and timely but the price was higher than competitors.
DNA did a fine job in cleaning our chimney, as well as assisting in making sure that the wood burning stove was properly placed. Dave sets the standard for courteous, efficient, and timely service. Elvin Kaplan
DNA Masonry did a great job at our home- installing a new insulated liner in our chimney. In addition they did a number of masonry projects due to old uninsulated thimbles throughout the house. The DNA team were kind, conscientious, thorough and very professional. We will recommend them to any one we know who needs masonry work!
Service was good and timely, but the price was higher than competitors. Stayed with DNA because they had worked on the chimney before but didn't feel great about the price difference.
Excellent service and craftsmanship. ighly reccommend
