Chimney Sweep & Cleaning

Creosote is a highly flammable, tar-like byproduct of wood combustion that builds up on your chimney flue walls over time. Using particulate extraction machines and mechanical whip gear, our technicians perform dust-free sweeping of wood stoves, open brick fireplaces, inserts, and furnace vents.

✓ Thorough brush-and-vacuum soot extraction and creosote cleaning
✓ Removal of Stage 1, 2, and unstable Stage 3 creosote glaze
✓ Safety inspection of the damper, smoke shelf, and hearth firebox

Chimney Repair

Exposed to harsh weather, chimney masonry decays over time. Water entering through a cracked crown or crumbling mortar joints causes destructive freeze-thaw cracking of the bricks.

✓ Precision tuckpointing and mortar joint restoration with matched brick composites
✓ Leaky crown rebuilds and weather-seal water-barrier applications
✓ UL-listed stainless steel liner installations for wood or gas systems

✓ Repair diagnostics for all major cooling equipment makes and models
✓ Energy Star certified high-SEER central AC replacements and duct assemblies
✓ Refrigerant leak pinpointing, pressure checks, and safe recharging

✓ Counter-rotating mechanical brushing to loosen stuck allergen deposits
✓ Organic sanitizing fog treatment to neutralize mold spores and odors

What your neighbors say

Verified reviews from homeowners across DC and Maryland.

"Excellent service! We called Moses HVAC & Chimney for a long-delayed chimney inspection and sweep. The crew arrived right on time, explained the levels of inspections, and used a specialized camera to show us the interior flue liner condition. Super clean, absolutely no mess in our living room!"

Richard L. Rockville, MD

"Our chimney crown was severely cracked, causing rainwater to leak down behind the hearth firewall. Moses HVAC rebuilt the masonry crown and applied a high-grade elastomeric water seal. We just had a huge rainstorm last night and the fireplace is bone dry."

Elena M. Bethesda, MD

"Outstanding experience from start to finish. The technician replaced our old, noisy air conditioner with a modern, quiet high-SEER condensing unit. Our DC row house stays cold even in the stickiest heat wave, and our electric bills are down."

David K. Washington, DC
