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.

AfterFast, Reliable Chimney Cap & Crown Across Mansfield
Chimney cap and crown repair in Mansfield typically runs $280-$750 for most homes, with custom stainless caps for prefab systems starting around $450. We’re usually on site within a few days of your call, and most jobs finish in a single visit.
We’ve been working on Mansfield chimneys since 1984, long enough to know that the “brick” fireplace in your 1970s colonial on Stearns Avenue or your ranch near the commuter-rail station is probably a factory-built zero-clearance unit, not masonry. That changes everything about how cap and crown work gets done. Our Chimney Cap & Crown team carries the right parts for prefab chase covers and metal crowns, not just traditional brick crowns, because that’s what Mansfield’s housing stock demands. Call (508) 545-9737. A live person answers, 24 hours a day.
Why Hearthstone Chimney Co. Is Mansfield’s Preferred Chimney Cap & Crown Company
Forty-two years in this trade means we’ve watched Mansfield grow from a quiet farming town to the bedroom community it is today, with Route 495 and the MBTA station drawing families to those 1970s-1990s colonials and ranches that dominate the neighborhoods. We know which builders used which prefab fireplace systems, and we stock chase covers and caps sized for them through our Fireplace Services in Mansfield.
Mansfield homeowners call us back because we document what we find. Every inspection ends with photos you can see and a plain-English verdict. No guessing, no upsell based on what you can’t verify. The 90-Day Done Right Promise backs every job in writing. If it’s not right, we come back. No paperwork, no arguing.
Our technicians are background-checked, uniformed, and trained to factory-built specifications most sweeps never encounter. Dispatch is coordinated from our Boston office, but crews serve Mansfield locally. We’ll be there when we say.
Our Chimney Cap & Crown Services in Mansfield
Cap Installation
New cap installation in Mansfield starts with identifying what system you actually have, and if your chimney needs more than a cap, we also handle Chimney Repair in Mansfield. On a prefab chimney, we install a chase cover with integrated cap, sized to the manufacturer’s flue diameter and with proper clearance for draft. On the older masonry chimneys near the town center, we fit a Gelco or Copperfield stainless cap with expanded metal mesh to keep out squirrels and spark. A square deal: no surprises on the bill. We agree on the price before we book.
Cap Replacement
Most cap replacements we do in Mansfield trace to rusted-through chase covers on 1970s-1990s prefab systems. The original galvanized sheet metal doesn’t survive our freeze-thaw cycles and Narragansett Bay moisture. We replace with 304 stainless or copper, depending on your preference and the exposure. If a wood stove insert was added later, the original cap may no longer cover the larger pipe. We size for what is there now, not what was there in 1978.
Crown Repair
True masonry crown repair applies to the pre-WWII capes and colonials near Mansfield’s town center, where clay tile liners and mortar crowns show age-related deterioration. We pour a new concrete crown with proper overhang and drip edge, or apply a bonded crown coating where the substrate is sound. We don’t recommend rebuilds without camera evidence you can see for yourself. Sometimes the crown can wait. We’ll tell you when.
Crown Coating
Crown coating is our most common crown service in Mansfield, and for good reason. The factory-built chase pans on prefab systems corrode at fasteners and seams long before the firebox fails. We clean the pan, treat corrosion, and apply a flexible crown coating rated for thermal cycling. This extends service life five to ten years on a system that might otherwise need full chase replacement. Done right, and we stand behind it.
Custom Cap
Mansfield’s energy-crisis wood stove inserts created a generation of chimneys with non-standard flue configurations. The insert collar, the second flue left open, the oversized pipe - none of these fit catalog parts. We measure on site and fabricate custom stainless caps with wider flashing flanges, multi-pipe accommodations, and animal screening sized to local squirrel and raccoon pressure. No waiting for shipped parts that don’t quite fit.
Multi-Flue Cap
Many Mansfield homes have two flues - one for the fireplace, one for the furnace or a second appliance - but only one cap from the original installation. A multi-flue cap covers both, prevents downdraft between flues, and stops rain from entering the unused opening. We size for the actual flue spacing, not guess from the ground.

Trusted Brands We Service in Mansfield
We work exclusively with professional-grade materials: Gelco stainless caps, Olympia Chimney chase covers, Famco custom-fabricated solutions, and Copperfield specialty fittings. No builder-grade substitutes. We stock the common Mansfield prefab sizes locally, so most cap and crown jobs don’t wait on shipping. When we encounter a wood stove insert mismatch or a corroded chase pan that needs custom work, we fabricate from Famco or Copperfield components rather than forcing a catalog part that won’t seal. The right material for the actual chimney, not the closest match in the truck.
Common Chimney Cap & Crown Problems We See in Mansfield Homes
- Rusted chase cover fasteners. The sheet-metal chase covers on 1970s-1990s prefab systems rust through at fasteners first, letting nor’easter moisture drip onto the smoke chamber. We see this on ranch-style homes near I-495 and in the Stearns Avenue area. The fix is stainless replacement, not more caulk.
- Insert collar creosote buildup. Energy-crisis wood stove inserts constrict the prefab flue’s designed draft, concentrating creosote at the collar-to-liner seam where a standard brush pass never reaches. This is invisible without pulling the insert, which we do during cap and crown inspection.
- Multi-flue caps that no longer cover. When a wood stove insert was added to one flue, the original cap often fails to cover the larger pipe or the second flue at all. Rain, animals, and spalling follow. We measure both flues and fit a proper multi-flue cap.
- Spalled crown concrete on pre-WWII masonry. The older capes and colonials near Mansfield’s town center suffer freeze-thaw spalling on clay tile crowns. Crown coating buys time; full crown replacement buys decades. We show you the camera footage and explain which applies.

FAQs - Chimney Cap & Crown in Mansfield
Look for a metal chimney chase on your roof rather than a brick chimney, or check inside the firebox for a manufacturer’s label, usually on the left or right side. The “brick” is often a refractory panel made to look like masonry, and the flue is a metal pipe, not clay tile. If you’re unsure, we’ll confirm during inspection and adjust our cap and crown approach accordingly. Call (508) 545-9737 for a free estimate.
The insert collar constricts your prefab flue’s designed draft, concentrating creosote at the seam where collar meets liner, a spot a standard brush can’t reach without pulling the insert. Primary-heat burning loads the system heavier than occasional fireplace use. We typically recommend Mansfield Chimney Cleaning & Sweep for primary-heat inserts annually, with camera inspection of the collar seam every other year. Call (508) 545-9737 to schedule.
Mansfield’s position at the collision of cold Arctic air and wet nor’easters carrying Narragansett Bay moisture creates aggressive freeze-thaw cycling that spalls masonry and corrodes sheet metal. The original galvanized chase covers on 1970s-1990s systems weren’t built for it. Stainless replacement lasts decades, not years. Call (508) 545-9737 for an exact quote on your chase cover.
For prefab chase pans with surface corrosion but sound structure, crown coating is often the right choice because it flexes with thermal expansion and seals against the moisture that defines our local climate. For masonry crowns with structural cracks, coating is a temporary patch at best. We show you the camera footage and recommend based on what we see, not a one-size-fits-all rule. Estimates are free - call (508) 545-9737.
Yes. The uncapped flue admits rain, animals, and downdraft that can damage the liner and introduce odors or carbon monoxide risk into the home. We see this frequently where a wood stove insert was added to one flue without updating the cap. A multi-flue cap sized to both openings solves it in one visit. Call (508) 545-9737 for a free inspection and firm quote.
