A simple cap or damper upgrade can save thousands in future repairs. Fairfield Chimney Services Group installs high-quality chimney caps, top-sealing dampers, and waterproofing systems to keep Connecticut weather from destroying your masonry. Our stainless steel and copper components block rain, downdrafts, and nesting animals, while energy-efficient dampers seal heat inside your home when the fireplace is not in use. Combined with our breathable waterproof coatings, your chimney stays dry, efficient, and worry-free year-round.
A chimney without a cap is like a house without a roof vent—it’s exposed. Rainwater that enters the flue mixes with soot to create acidic residue that eats away clay tiles, metal liners, and dampers. Birds and squirrels frequently nest inside uncapped chimneys, blocking exhaust and creating serious fire risks. A properly fitted cap stops debris and animals, prevents sparks from escaping, and protects against moisture intrusion—the leading cause of chimney deterioration in Fairfield’s coastal climate.
All our caps feature fine stainless-steel mesh that blocks embers and critters without restricting airflow. Installation includes sealed fasteners and weather-resistant adhesives designed for long-term performance.
Traditional throat dampers often warp, rust, or fail to seal completely—allowing warm air to escape and cold drafts to enter. Top-sealing dampers solve this by closing at the flue top with a stainless steel spring-loaded gasket. When closed, they create an airtight seal that can save homeowners up to 15–20% on energy bills. One pull of the handle inside your fireplace opens it for use. They also block rain, animals, and downdrafts in one design, making them ideal for older Fairfield homes losing heat through the chimney.
Moisture is the enemy of masonry. Without protection, rainwater seeps through porous brick, freezes, and expands—causing cracks and leaks that lead to interior stains and structural damage. We apply breathable, professional-grade waterproofing sealants formulated for chimney surfaces. Unlike paint or silicone, our products let vapor escape while blocking liquid water. The result: a dry, strong chimney that resists freeze–thaw damage and efflorescence for years.
Chimney caps and top-sealing dampers are small upgrades that make a big difference. By sealing heat inside during cold months and blocking humid air during summer, they stabilize indoor comfort and reduce HVAC strain. Waterproofed brickwork prevents costly freeze–thaw repairs, helping you save both on utilities and long-term maintenance.
Our technicians use commercial-grade sprayers to saturate masonry evenly, applying two coats of silane–siloxane sealant. This transparent barrier lasts up to ten years depending on exposure. After treatment, water beads off the surface, but the brick continues to “breathe.” Annual inspections ensure continued protection against leaks and cracks.
