Chimney Repair
Cracked crowns, spalling brick, failed flashing, damaged flue tiles - we trace every chimney problem to its root cause and repair it properly, so you fix it once instead of chasing symptoms every spring.
Learn more →
Chimney Leak Repair
Water finds every weakness in a chimney. We trace leaks to their true source — crown, flashing, masonry, or cap — and repair the cause, not just the stain.
Learn more →
Chimney Flashing Repair
The joint where your chimney meets the roof fails before almost anything else on the house. We rebuild step and counter-flashing the right way — cut into the mortar, not smeared over it.
Learn more →
Chimney Crown Repair
Cracked or crumbling chimney crown? We seal, resurface, and rebuild cast-concrete crowns engineered to survive New England freeze-thaw and protect every brick below.
Learn more →
Chimney Waterproofing & Sealing
Brick and mortar drink water like a sponge — then New England winter freezes it. Our breathable siloxane treatments stop the absorption before spalling starts.
Learn more →
Chimney Liner Installation & Relining
UL-listed stainless steel liner installation and full chimney relining, correctly sized to your appliance and insulated for New England winters.
Learn more →
Chimney Cap Installation & Replacement
An uncapped flue is an open hole in your roof. We install stainless and copper chimney caps sized for proper draft that keep out rain, squirrels, raccoons, and nor'easter downdrafts.
Learn more →
Chimney Masonry Repair & Repointing
Repointing, tuckpointing, and brick replacement done the old-school way: mortar analyzed and matched to your chimney, joints ground to sound depth, and work that disappears into the original masonry.
Learn more →
Chimney Rebuilds & Restoration
When repointing can no longer save a chimney, we take it down to sound masonry and build it back correctly - partial roofline-up rebuilds, full reconstructions, and historic restorations with matched brick.
Learn more →
Creosote Removal
Specialized removal of heavy stage-2 and glazed stage-3 creosote using rotary equipment and chemical treatment — the buildup an ordinary brush sweeping cannot touch.
Learn more →
Animal & Nest Removal
Humane removal of birds, squirrels, raccoons, bats, and nesting debris from your chimney, followed by a full flue cleanout and exclusion work so wildlife never moves back in.
Learn more →
Draft & Smoke Problem Repair
We diagnose why your fireplace smokes, backdrafts, or refuses to draw — flue sizing, smoke chamber geometry, house pressure, wind effects — and fix the actual cause, not the symptom.
Learn more →
Damper Repair & Replacement
A stuck, rusted, or warped damper leaks heat all winter and smoke all season. We free, rebuild, and replace throat dampers and install energy-sealing top-mount dampers.
Learn more →
Fireplace & Firebox Repair
Firebox rebuilds, refractory panel replacement, smoke chamber parging, damper repair, and hearth restoration that make an aging fireplace safe to light again.
Learn more →

A Chimney Company Built for New England Homes
A chimney in Massachusetts lives a harder life than almost anywhere else in the country. It bakes through humid summers, soaks up wind-driven rain in the fall, and then endures dozens of freeze-thaw cycles every winter — each one prying at mortar joints, crown cracks, and brick faces. Add in the region's housing stock, much of it built between the 1850s and 1950s with unlined or clay-lined flues never designed for modern heating appliances, and annual professional attention stops being optional. It's how you keep a chimney from becoming either a water problem, a fire hazard, or a five-figure rebuild.
Upside Down Chimney Sweeps exists for exactly this. We sweep and inspect to NFPA 211, the national standard fire marshals and insurance companies reference. We scan flues with cameras so you never pay for guesswork. We repair crowns, flashing, and masonry with materials matched to New England conditions, install UL-listed stainless steel liners sized correctly for the appliance they vent, and cap every flue against rain, downdrafts, and animals. When a storm or chimney fire forces the issue, we handle emergency calls with priority scheduling.
