Fireplace cleaning isn't the same as chimney sweeping. Sweeping cleans the flue. Fireplace cleaning handles the firebox, smoke chamber, damper, hearth, and — for gas — the burners, logs, and ignition system.

We clean and service all four major fireplace types on Long Island:

Wood-burning (masonry + metal)

  • Firebox brushed and vacuumed
  • Smoke chamber cleaned (parge coat inspected)
  • Damper tested and cleaned
  • Andirons and grate cleaned
  • Hearth and surround vacuumed
  • Level I inspection included

Gas (vented + vent-free)

  • Burner assembly cleaned
  • Ceramic logs cleaned and arranged properly
  • Thermopile/thermocouple tested with multimeter
  • Pilot assembly cleaned and tested
  • Glass doors cleaned (gas inserts)
  • Gas line leak test with combustible gas detector
  • Carbon monoxide detector test
  • NFI-certified technician

Pellet stove

  • Burn pot and heat exchanger cleaned
  • Ash pan emptied and cleaned
  • Pellet auger inspected
  • Vent pipe sweep
  • Gasket inspection

Fireplace inserts (wood or gas)

  • Full unit removed for access when needed
  • Firebox and heat exchanger cleaned
  • Chimney liner (insert liner) swept
  • Reinstall and re-seal

When to call us

  • Annually for any fireplace used 10+ times a year
  • Before first use of the season
  • After a chimney fire (required Level II first)
  • If pilot won't stay lit (gas)
  • If flames are orange instead of blue (gas combustion issue)
  • If glass is smoking up quickly (gas — combustion problem)
  • If firebox has soot buildup (wood — possibly improper burning)

Frank came out to sweep our chimney in Hicksville and found a crack in the flue tile I never would have seen. He showed me the camera footage, gave me options, and never pressured me. We scheduled a reline and it was done in two days. Best contractor experience I've had.

Had a bad experience with another chimney company two years ago — they wanted to sell me a whole new liner for $6,500. Frank came out, did a Level II inspection, and told me the existing liner was fine. Just needed a sweep. Saved me thousands.

Paul the mason repointed our 1956 chimney and matched the mortar color perfectly. You can't tell where the new work ends. On time, clean, fair price. We're calling them every year from now on.

Frequently asked

About fireplace cleaning

Yes. Less often than wood — every 2-3 years minimum — but the burner assembly, glass, and safety components need service to stay safe and efficient.
