Every job is handled by licensed, insured technicians with upfront written pricing, and backed by a workmanship guarantee — free estimates for all of Boston and nearby areas.
Boston’s fluctuating humidity and winter soot buildup make regular sweeping non-negotiable. We clear every flue—masonry, prefab, or metal—to Massachusetts code, using HEPA vacuums to contain dust in your Back Bay brownstone or South End loft. No guesswork: we measure creosote levels on-site and provide a before/after report. Expect zero mess, zero surprises, and a chimney that draws like new. Skip the ‘premium’ add-ons—this is the core service that keeps your fireplace safe and efficient year-round.
Request this service →This isn’t a sales pitch; it’s a compliance check. We inspect your chimney from roof to firebox, flagging cracks, deteriorating mortar, or obstructions that could trap carbon monoxide in your Fenway high-rise or Jamaica Plain two-family. Required by Massachusetts code for wood-burning fireplaces, this 30-minute Level 1 sweep meets insurance requirements and costs less than a skipped inspection. No cameras, no upsells—just a clear report on what’s safe and what needs attention.
Request this service →When your chimney’s history is unclear—like after a Cambridge condo purchase or a suspected chimney fire in your Brookline home—we deploy a 360° camera to spot cracks, spalling bricks, or liner gaps that a visual inspection misses. Massachusetts requires this for property transfers or after a chimney fire; we provide timestamped footage and a written report for your insurer or buyer. Think of it as a CT scan for your chimney: precise, thorough, and free of vague ‘possible issues’.
Request this service →A missing cap is the #1 cause of chimney damage in Boston’s coastal climate. We install custom caps that block rain, squirrels, and wind-driven debris—extending your chimney’s life by years. No more $5,000+ rebuilds from water damage. We match your flue size, secure it to code, and guarantee it won’t fly off in a nor’easter. Skip the cheap big-box caps; these are built to last in Massachusetts weather.
Request this service →Boston’s historic homes and modern builds alike suffer from freeze-thaw damage. We repoint mortar joints, rebuild chimney crowns, and seal cracks with high-temperature mortar that won’t crack in winter. No patchwork—just structural repairs that meet Massachusetts building codes. We photograph the damage pre-repair and provide a detailed scope of work, so you know exactly what you’re paying for. No surprises, no delays.
Request this service →A fireplace that smokes, smells, or won’t stay lit wastes fuel and risks carbon monoxide leaks. We service dampers, replace cracked fireboxes, and tune gas logs for proper combustion in your Beacon Hill townhouse or South Boston triple-decker. Whether it’s a 1920s masonry unit or a modern insert, we restore draft, seal leaks, and ensure your chimney meets current safety standards. No band-aid fixes—just lasting performance you can count on.
