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.

We’re Hearthstone Chimney Co., and our crews have been working on Dedham’s older masonry chimneys for over 42 years.

Why Hearthstone Chimney Co. Is Dedham’s Preferred Chimney Cap & Crown Company
Dedham homeowners call us because we’ve earned a reputation for plain talk and no upsell. Our Chimney Cap & Crown team documents every recommendation with photos you can see yourself, and our 90-Day Done Right Promise is in writing with no arguing.
We dispatch to Dedham from our Boston office, so we’re rarely more than 20 minutes from homes in Oakdale, the historic district, or near Dedham Square. That matters when you’ve got water coming through the flue or a crown crack that’s widening after every freeze-thaw cycle.
Our technicians are background-checked, uniformed, and trained to navigate Dedham’s layered chimney history - original colonial-scale flue openings, mid-century clay liner retrofits, and modern inserts forced into systems never re-engineered for them. We’ve learned that in a town with housing stock dating to the 1600s, every chimney tells a story, and we read it with a camera before we quote a dollar.

Our Chimney Cap & Crown Services in Dedham
Cap Installation
A proper chimney cap in Dedham isn’t decorative - it’s the first defense against the valley fog and driving rain that accelerate deterioration on older brick. We measure your flue precisely, account for any liner protrusion or irregular colonial brickwork, and install caps from Gelco and Olympia Chimney that vent properly while keeping critters and weather out. Most standard cap installations in Dedham run $280-$550 and are done in under two hours.

Cap Replacement
Dedham’s original caps, where they exist at all, are often rusted galvanized or homemade wire screens that do nothing for water intrusion. We remove the old unit, inspect the flue top for hidden damage, and fit a replacement sized to your actual chimney - not a big-box guess. If your cap blew off in a Nor’easter or finally rusted through after twenty years, we’ll get you fixed with no-hassle upfront pricing and a photo report of what we found underneath.

Crown Repair
This is where Dedham’s geography hits hardest. Crowns on multi-flue 1800s chimneys crack along mortar joints and pull away from the brick, letting Charles River valley moisture wick straight into the flue. North-facing and riverside exposures fail fastest. We grind out deteriorated crown material, re-form with proper slope and overhang, and finish with a drip edge that sheds water away from the brick face. Crown repairs in Dedham typically range $650-$1,200. Full rebuilds on large colonial chimneys with multiple flues can reach $1,400-$1,800.

Crown Coating
For crowns with minor cracking that hasn’t yet compromised the structure, we apply professional-grade flexible coating systems from HeatShield that bridge hairline cracks and restore waterproofing without full reconstruction. This isn’t a paint job - it’s a formulated repair system designed for chimney crowns that expand and contract through New England’s freeze-thaw cycles. We’ll show you the camera footage and tell you honestly whether coating will hold or if the crown needs more. In Dedham’s wet valley climate, we see too many coatings applied over failing substrate; we don’t do that.

Multi-Flue Cap
Dedham’s pre-1940 housing stock near Dedham Square and Oakdale includes colonial-scale, multi-flue brick chimneys often fitted decades later with clay-tile liners that were never sized to the fireplaces they now serve. Sitting in the Charles River valley, these north-facing and riverside bricks soak up ground fog, so crowns and mortar joints fail faster here than on higher, drier ground in neighboring towns. A multi-flue cap covers the entire chimney top with a single engineered unit, sealing between flues and shedding water off the crown entirely. We fabricate and install multi-flue caps from Famco and Gelco, measured to your chimney’s exact footprint, with proper clearances for each flue. These run $750-$1,400 depending on size and material.

Custom Cap
Some Dedham chimneys defy standard sizing. Colonial-era fireplaces with irregular brick openings, flues that angle or step, or historic preservation requirements mean off-the-shelf caps won’t fit or won’t vent safely. We measure, fabricate, and install custom caps in copper, stainless steel, or galvanized - whatever suits your chimney’s needs and your preference. Custom work starts around $900 and is quoted after measurement.

Trusted Brands We Service in Dedham
We stock professional-grade materials from Gelco, Olympia Chimney, Famco, and HeatShield - no builder-grade substitutes. For Dedham customers, that means faster turnaround because we’re not ordering parts after we diagnose; we’ve got the cap or coating system your chimney needs already on the truck. These are the same brands specified by chimney professionals nationwide, and we use them because they hold up to Dedham’s wet winters and freeze-thaw punishment. When we recommend a multi-flue cap or crown rebuild, it’s with components we’ve installed on hundreds of local chimneys and watched perform year after year.
Common Chimney Cap & Crown Problems We See in Dedham Homes
- Crown cracks along mortar joints on multi-flue chimneys. Dedham’s 1800s brick chimneys were built with separate flue walls that move slightly at different rates. The crown concrete bridges these joints, cracks form, and Charles River valley moisture pours in every spring thaw. We see this weekly on homes near the river and in the historic district.
- Spalling brick on north-facing exposures. Ground fog from the Charles River valley keeps north-side brick wet longer than south-facing brick in the same neighborhood. By the time homeowners notice interior water stains, the crown has been compromised for multiple seasons and the freeze-thaw damage is accelerating.
- Colonial firebox openings paired with undersized clay liners. Older homes near Dedham Square frequently have fireplaces whose opening-to-flue-size ratio violates modern draft standards - a design common before standardization - causing chronic backdrafting and faster-than-normal creosote buildup that surprises homeowners who only use the fireplace a few times a season. No cap, however well-built, can fully compensate for a fundamentally mismatched system, but a properly engineered custom cap with correct overhang and venting can improve draft measurably while we address the liner separately.
- Mid-century clay liner retrofits misaligned at the smoke chamber. Oil-era liner jobs in Dedham’s older stacks were often rushed, with liners cracked or offset where they meet the firebox. Smoke leaks into the chimney wall, stains appear, and homeowners assume they need a crown rebuild when the real problem is hidden liner failure. Our Level 2 camera inspection catches this before any cap or crown work is quoted.

On a late-1890s colonial near Dedham Square, we ran a Level 2 inspection and found a crown cracked clean through with spalling on the north riverside face and a clay-tile flue liner the homeowner’s wood insert had outgrown. We documented everything on camera, installed a custom multi-flue copper cap sized to the original colonial openings, and rebuilt the crown with a proper overhang and drip edge. The homeowner watched the footage before we recommended a single dollar of work.

FAQs - Chimney Cap & Crown in Dedham
A multi-flue cap is usually the better choice for Dedham’s older two-flue chimneys because it covers the entire crown, sheds water off the brick, and eliminates the gap between separate caps where valley moisture collects. Two individual caps can work if your flues are widely separated and the crown between them is in perfect condition, but that’s rare on colonial-era chimneys where the flues share a common wall. We’ll measure and show you both options on camera before you decide. Call (857) 754-5607 for a free estimate.
North-facing brick in Dedham’s Charles River valley stays wet longer from ground fog and gets less sun to dry it, so freeze-thaw damage concentrates there. We’ve rebuilt crowns on south sides that were fine while the north face was spalling badly. A proper crown rebuild with correct slope and drip edge, combined with a full-coverage multi-flue cap, redirects water and gives all exposures equal protection. Call (857) 754-5607 and we’ll assess whether repair or full rebuild is warranted.
A new cap can improve draft modestly by reducing wind-induced pressure changes at the flue top, but it cannot fix a fundamentally mismatched firebox-to-flue ratio common in Dedham’s colonial-era fireplaces. If your opening is oversized for the clay liner installed decades ago, you need a liner evaluation, not just a cap swap. We run the camera, measure the ratio, and tell you straight whether a cap alone will help or if the liner needs addressing first. Estimates are free - call (857) 754-5607.
You watch the footage yourself. Our Level 2 inspection ends with photos and video you can see, plus a plain-English verdict. We show crown cracks, spalling depth, liner condition, and water intrusion paths. Nothing is recommended without camera evidence, and we’ll tell you plainly when work can safely wait. The 90-Day Done Right Promise backs every job in writing with no arguing - we have no incentive to sell you work you don’t need, because we’d only be back to fix our own mistake. Call (857) 754-5607 to schedule your inspection.
We install Gelco and Olympia Chimney caps for standard applications, and fabricate custom multi-flue and specialty caps from Famco components when Dedham’s irregular colonial flue openings require it. All are professional-grade, not big-box substitutes, and sized to your chimney after direct measurement. For crown coating and repair, we use HeatShield systems formulated for freeze-thaw durability. We’ll match the right brand and material to your chimney’s condition and your budget. Call (857) 754-5607 for specifics on your job.
