A Level 1 sweep isn’t just a quick brush-up—it’s a surgical deep-clean of your Cohasset chimney’s flue, smoke chamber, and damper. We remove every trace of creosote, the tar-like byproduct of incomplete combustion that coats your flue like varnish. Left unchecked, it can spark chimney fires or block deadly carbon monoxide. Our HEPA vacuums capture 99.9% of debris, so your home stays pristine. We also check for cracks in Cohasset’s older masonry, where water intrusion can silently rot your chimney from the inside out. Expect a spotless flue and a damper that seals like new—no more cold drafts when your fireplace isn’t in use.
Request this service →Most sweeps call this a ‘video inspection,’ but we treat it like a CT scan for your chimney. Using 4K cameras, we navigate bends and offsets to inspect every inch of your flue, from the Cohasset rooftop to the smoke shelf. We look for hidden dangers: spalling bricks from coastal humidity, cracked flue tiles from winter freezes, or obstructions like bird nests (a common issue in Scituate’s older chimneys). This isn’t a cursory peek—it’s a forensic analysis that reveals problems before they become emergencies. Results are recorded and shared with you in real time, so you see exactly what we see.
Request this service →Your chimney crown is the first line of defense against Cohasset’s coastal storms and freeze-thaw cycles. Cracked or eroded crowns let water seep into the masonry, causing bricks to spall and mortar to crumble. We rebuild crowns with a custom-mixed, waterproof mortar that resists salt air and icing. Unlike patchwork fixes, our method includes a full repointing of the chase (the brick enclosure around your flue) to ensure no moisture sneaks in. Homeowners in Cohasset’s historic district trust us to preserve their chimneys’ integrity without the invasive cost of full rebuilds.
Request this service →If your Cohasset home has an older masonry fireplace, the flue may be too wide, too rough, or too cracked to draft properly. A stainless-steel liner solves all three problems. It smooths the flue’s interior, improving airflow and reducing creosote buildup—a critical fix for homes in Scituate’s windy coastal areas. Liners also prevent heat transfer to combustible materials, meeting modern safety codes. We install them in a single visit, with no demolition required. Your fireplace will burn cleaner, hotter, and safer, all while extending the life of your chimney.
Request this service →Salt air and Cohasset’s damp winters are a chimney’s worst enemies. Our siloxane-based sealer penetrates deep into masonry, repelling water while allowing vapor to escape—so your chimney can ‘breathe’ without absorbing moisture. We apply it to every brick and mortar joint, including the chase, to create a waterproof barrier that lasts for years. Unlike cheap sealers that peel or trap moisture, ours is warrantied for 10 years. Homeowners in Cohasset’s beachfront homes swear by it after seeing their chimneys stay dry through Nor’easters.
Request this service →A blocked or damaged chimney isn’t just an inconvenience; in Cohasset’s older homes, it can become a silent killer. Our emergency team responds to calls 24/7, diagnosing issues like collapsed flue tiles, animal intrusions (raccoons love Cohasset’s chimneys), or creosote fires that warp the flue. We clear obstructions, repair damaged liners, and restore safe draft—often the same day. All emergency calls include a full Level 2 inspection to ensure no secondary hazards remain. Your safety isn’t negotiable, and neither is our response time.
