Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Hearthstone Chimney Co. Is Sharon’s Preferred Chimney Cap & Crown Company
Sharon homeowners tend to stay put. The 1960s-1980s colonials near Pond Street and the converted cottages around Lake Massapoag have been in families for decades, and the people who own them remember every contractor who oversold or disappeared. We don’t disappear. We’ve served Norfolk County communities since 1984, and our Chimney Cap & Crown in Sharon work is backed by the 90-Day Done Right Promise - in writing, no arguing.
Our Level 2 camera inspections end with photos you can see and a plain-English verdict. Nothing is recommended without evidence you can hold in your hand. That matters in Sharon, where we’ve seen too many homeowners told they need a full liner rebuild when the real problem was a cracked crown letting water into the smoke chamber.
Our technicians are background-checked, uniformed, and carry professional-grade materials from Gelco, Olympia Chimney, and Famco on every truck. Most cap and crown jobs in Sharon finish in one visit. The number on your estimate is the number on your invoice.
Calls are answered by a live person, every hour of every day. Not a voicemail. Not a callback queue.
Our Chimney Cap & Crown Services in Sharon
Cap Installation
New cap installation in Sharon runs $280-$550 for a standard single-flue stainless steel unit, and $650-$1,200 for a custom multi-flue cap on a larger colonial or cottage chimney. We size caps to the flue, not the other way around. Around Lake Massapoag, we regularly find two-flue chimneys serving a basement boiler and a first-floor fireplace - each flue needs its own properly sized cap, or a single custom cover with separate compartments. We measure, photograph, and fabricate to fit. No guesswork.

Cap Replacement
Cap replacement in Sharon typically costs $220-$480, depending on whether the existing flue is intact and the mounting surface is sound. The old caps we remove from Sharon chimneys are often rusted through, improperly sized, or installed with no consideration for the flue liner condition beneath. We don’t swap hardware blindly. Our Chimney Cap & Crown team inspects the flue with a camera before recommending any cap, because a new cap on a deteriorating liner is money thrown away.

Crown Repair
Crown repair in Sharon ranges from $350 for crack sealing and waterproofing to $850-$1,200 for a full pour of new concrete or specialty crown coating. Sharon’s freeze-thaw cycle is brutal on crowns. Water seeps into hairline cracks in October, freezes by Thanksgiving, and spalls off chunks of concrete by March. The 1960s-1980s colonials with original crowns are especially vulnerable - 40-60 years of thermal cycling leaves the crown separated from the top course of brick, directing water straight into the chimney interior.

Crown Coating
Crown coating with a professional-grade flexible sealant runs $320-$580 in Sharon and extends the life of a structurally sound crown by 10-15 years. We use products formulated for New England’s temperature swings, not the thin brush-on coatings sold at hardware stores. A proper crown coating is structural, not cosmetic. We apply it to clean, dry concrete after repairing cracks and rebuilding deteriorated edges. On lake-adjacent cottages where the crown has minor cracking but the masonry beneath is still sound, this can be the difference between a $400 coating and a $3,000 rebuild.

Trusted Brands We Service in Sharon
We stock and install professional-grade caps and crown materials from Gelco, Olympia Chimney, and Famco - brands that engineer for coastal New England’s salt air, freeze-thaw cycling, and heavy heating-season use.

The cap that goes on your chimney is the same spec we’d put on our own.
Common Chimney Cap & Crown Problems We See in Sharon Homes
- Mortar-joint and brick-face spalling on lake-adjacent cottages. Bare-brick chimneys with no flue liner absorb water each winter. The crown cracks or pulls away from the top course, and freeze-thaw cycling pops the face off bricks by spring. We see this on cottages off North Main Street and around Lake Massapoag where the original summer-only construction was never meant to handle six months of continuous heating.
- Clay tile liner cracking in 1960s-1980s colonials. Forty to sixty years of freeze-thaw cycling in Sharon’s continental climate leaves clay tiles cracked, displaced, or collapsed at the mortar joints. Heat and creosote reach the surrounding masonry. A cracked crown accelerates the damage by letting water pool on the smoke shelf. Standard visual inspection from the firebox misses most of this.
- Caps installed without camera verification of the flue beneath. A company sells a shiny new cap for a draft problem that actually lives in a cracked liner, damaged smoke chamber, or stuck damper. The cap goes on. The problem stays. Six months later, the homeowner has a $400 cap and a $2,500 liner repair. We don’t do that. Camera first. Verdict second. Cap third.
- Crown deterioration masked by fresh paint or surface sealers. Some Sharon homeowners have had a previous contractor “waterproof” a crown that was already structurally compromised. The coating looks fine for a season or two, then peels away with chunks of concrete attached. We strip failed coatings, assess the substrate, and rebuild or recoat based on what the crown can actually support.

FAQs - Chimney Cap & Crown in Sharon
Yes. A Level 2 camera inspection is essential in Sharon because the housing stock hides serious problems a visual check from the firebox cannot see. Around Lake Massapoag, we regularly find bare-brick chimneys with no liner beneath what looks like a sound crown. In the 1960s-1980s colonials, cracked clay tiles hide behind intact-looking mortar. We document everything on camera, explain it in plain English, and only then recommend cap or crown work. Call (508) 545-9737 to schedule - estimates are free.
Your crown is likely original to a 1960s-1980s construction and has endured 40-60 years of freeze-thaw cycling without proper maintenance. Sharon’s average annual snowfall near 50 inches, combined with overnight lows in the single digits, drives water deep into micro-cracks, where expansion forces progressively fracture the concrete. The crown may also have been poured without an overhang or drip edge, directing water straight down the chimney face. We assess whether repair, coating, or full rebuild is appropriate based on camera findings - not guesswork. Call (508) 545-9737 for an inspection.
A custom multi-flue cap sized to your exact flue dimensions and spacing, fabricated from stainless steel or copper by a manufacturer like Olympia Chimney or Famco. The two-flue colonial chimneys common in Sharon neighborhoods near Pond Street and Bay Road typically have a boiler flue and a fireplace flue with different diameters and separations. A single cap with separate compartments prevents cross-drafting and keeps debris and animals out of both flues. We measure with a camera and tape, then fabricate to fit. Call (508) 545-9737 for exact sizing and pricing.
No. A cap and crown manage water and debris at the top of the chimney. They do nothing to contain heat, creosote, or combustion gases inside an unlined flue. Running a wood insert or stove through bare brick is a fire and carbon monoxide hazard, and no reputable technician should cap that chimney without first addressing the liner. We were called out to a converted cottage off North Main Street near Lake Massapoag where the owner had run a wood insert every winter for fifteen years and assumed the chimney was “fine” because it was original. A Level 2 inspection with our camera showed bare brick with no flue liner, third-degree creosote glazing the smoke chamber, and a chimney crown that had cracked into three pieces, letting meltwater drip straight onto the masonry. We documented everything on camera for the homeowner, installed a HeatShield-restored flue liner, poured a new crown, and topped the stack with a custom multi-flue cap sized to the two flues. Call (508) 545-9737 - we’ll show you exactly what you have.
Every chimney in Sharon should receive a Level 2 inspection annually, ideally in late summer before the heating season begins. Sharon’s long, cold heating season - with overnight lows regularly in the single digits and average snowfall near 50 inches - drives heavy creosote accumulation and accelerates masonry deterioration. For converted Lake Massapoag cottages with unlined or questionably lined chimneys, we recommend inspection before the first fire each fall. For 1960s-1980s colonials with aging clay tile liners, the same annual schedule applies, with particular attention to crown condition after hard winters. Call (508) 545-9737 to book your pre-season inspection - estimates are free.
