Belmont's No-Nonsense Chimney Experts — Safe, Clean, Done Right

The honest answer: if you burned wood last season, it needs sweeping regardless of how little you used it. Even one cord of wood produces enough creosote for a Level 1 buildup. Gas appliance flues should be inspected annually even if sweeping is less frequent. Do not skip — the cost of a sweep is trivial compared to a chimney fire.

Not automatically, but it raises the odds significantly. Pre-war chimneys were built without flue liners or with clay tile liners that are now commonly cracked or deteriorated. A video camera inspection will give you a definitive answer. Many older Belmont homes need liner upgrades when changing to gas appliances or if the original tile has spalled.

A Level 1 checks accessible areas of a properly maintained chimney — suitable for annual service when nothing has changed. A Level 2 includes a full video scan of the flue interior and is required when buying or selling a home, after any chimney fire, or following severe weather. If you are unsure, request a Level 2 — the extra detail is almost always worth it.

That is a common and potentially dangerous myth. Gas fireplaces and inserts do produce moisture, carbon residue, and occasionally bird or rodent nesting in the flue. The venting system can corrode or block without any visible warning. Annual inspection of gas appliance venting is recommended by both NFPA 211 and appliance manufacturers — and required for some homeowner's insurance policies.

Yes, in most cases. Once the sweep is complete, the firebox is cleaned out and the damper is confirmed operational, your fireplace is ready to use. The only exception is if we find a condition — like a cracked liner — that makes use unsafe. We will tell you clearly before we leave whether your fireplace is cleared for use or needs a repair first.

Faster than most homeowners expect. A single winter with an unprotected cracked crown or missing cap can allow enough water infiltration to cause significant spalling and mortar joint failure. The freeze-thaw cycle in Greater Boston typically runs from November through March, giving water dozens of expansion cycles. Preventive cap and crown maintenance in fall is the most cost-effective protection available.

Ask for their Massachusetts HIC (Home Improvement Contractor) registration number and verify it at the state's online portal. Request a certificate of insurance naming you as an additional insured — a legitimate company will provide this without hesitation. CSIA certification is a strong indicator of technical competence. Steves Brothers Chimney carries all required credentials and will provide documentation on request.

Stage 1 creosote is a light, dusty soot that brushes away easily. Stage 2 is a flaky, tar-like crust that requires rotary tools. Stage 3 is a hardened, glazed coating that is extremely difficult to remove and dramatically elevates fire risk. Stage matters because the cleaning method, time required, and cost increase significantly with each stage — and Stage 3 sometimes requires chemical treatment or liner replacement.
