A chimney is a machine for holding fire in the place you decided to put it. Ours is the upkeep of that decision.

Video scan of every foot of flue — required at property sale, fuel change or after any chimney fire
Stainless reline$2,400–3,600

What we do
The three trades inside the trade
The sweep
First-degree creosote — flaky, soot-heavy — brushes out in an hour behind a sealed hearth and a HEPA vacuum. Second degree has hardened into plates and gets the rotary head; third degree, the glazed tar that chimney fires are made of, gets chemical treatment and a follow-up camera pass. The report grades what we found, degree by degree, foot by foot.
The reline
A cracked clay tile flue cannot be swept safe — it can only be relined. We pull the old tiles where the joints allow, drop a rigid 316Ti stainless liner one section at a time, wrap it in insulation so the flue gases stay hot and draft clean, and draw-test the finished assembly before the stove is lit again.
The masonry
Millhaven brick is a hundred years old and knows it: joints gone to sand, crowns cracked through, the odd spalled face shedding freeze-thaw every spring. We grind out to sound mortar, re-point in a mix matched to the original lime content, and rebuild crowns that shed water instead of drinking it.

Recent chimneys
Six jobs from the last year, photographed from the roof and the firebox. Sweeps, relines and re-pointing — no two chimneys in the district are the same age or the same trouble.
The districts say
Kept burning, kept standing
The camera found a third-degree glaze a previous outfit had brushed over and called clean. Hearthstone treated it, re-swept, and showed me the footage both times — the difference was not an opinion, it was a wall. That flue would have burned the street down eventually.
Level 2 scan at the sale of our 1911 four-square found two cracked tiles and a crown that was mostly optimism. The reline quote was itemized to the fitting, the crew laid runners the whole way to the roof, and the woodstove draws better than it has in thirty years.
They re-pointed our chimney to match 1900s lime mortar — the mason next door came out to watch, which is the review. Snow used to sit in the joints all winter; now it slides off the crown like it was paid to.
The autumn sweep calendar fills by mid-September — book before the first fire. (555) 012-5541 · sweeps@hearthstonechimney.example
