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 Lynnfield
Chimney cap and crown work in Lynnfield typically runs $340-$890 depending on whether you’re covering a single flue or a multi-flue stack, and most jobs are completed in one visit with materials sized on-site. If you’re calling from one of the town’s 1960s colonials near Pillar Road or a newer build off the Upper Common, we’ll dispatch from our Boston office and have a technician out to you promptly. Call (857) 364-8219 - a live person answers, 24 hours a day.
We’ve been working on Lynnfield chimneys for decades, and the pattern here is distinct from coastal Essex County towns. The town’s core neighborhoods - the post-war buildouts around Main Street, the cape-cod clusters near Route 129, and the larger colonials that came later - sit far enough inland that freeze-thaw cycling hits harder than in Wakefield or Peabody. Wet snow piles up, thaws fast, and water finds every crack in a crown or gap in a cap. Our Chimney Cap & Crown team knows the local housing stock well enough to spot trouble before it becomes a leak into your attic or down your firebox.
Why Hearthstone Chimney Co. Is Lynnfield’s Preferred Chimney Cap & Crown Company
Lynnfield homeowners tend to stay put. They’ve raised families in these houses, watched the oil boiler get swapped for high-efficiency gas, and they notice when a new water stain appears above the fireplace. We earn their trust by documenting what we find - photos of the crown, the flue condition, the cap fit - and explaining it in plain English before any work starts.
Our reputation here is built on showing up when we say we will, finishing in one visit, and standing behind the result. The 90-Day Done Right Promise means if a cap doesn’t fit right or a crown coating fails, we come back - in writing, no arguing. That’s the Keystone Standard we’ve operated under since 1984. Calls are answered by a live person around the clock, not a callback queue. Our technicians are background-checked, uniformed, and carry professional-grade materials from Gelco, Copperfield, and Olympia Chimney on every truck.
Dispatch and scheduling are coordinated from our Boston office, but crews serve Lynnfield locally and know the difference between a 1962 cape on the south side and a 1995 colonial off Walnut Street.
Our Chimney Cap & Crown Services in Lynnfield
Cap Installation
New cap installation in Lynnfield usually means addressing a chimney that’s been open too long. On the town’s original 1950s-1970s stock, we often find multi-flue stacks where only the fireplace flue was ever capped - the boiler flue got a scrap of sheet metal or nothing at all. A proper installation starts with measuring every flue, checking clearances, and selecting a cap that ventilates correctly while keeping out rain, snow, and the squirrels that are active through Lynnfield’s wooded lots. Single-flue caps start around $340 installed; multi-flue systems run $520-$780 depending on span and material.
Cap Replacement
Replacement caps in Lynnfield fail for predictable reasons. Cheap galvanized units from the hardware store rust through in three to five years, especially with the road salt in the air from Route 1 and I-95. Factory-built fireplace caps in the 1980s-2000s Upper Common homes often don’t match the manufacturer’s termination specs and have warped or blown off in nor’easters. We replace with stainless steel or copper caps from Famco and Olympia Chimney, sized to the flue, not the shelf. Most replacements are done in under two hours.
Crown Repair
Crown repair is where Lynnfield’s inland climate shows its teeth. The crown - the concrete or mortar slab that seals the top of a masonry chimney - takes the full force of freeze-thaw cycling. Water seeps into hairline cracks, expands overnight when temperatures drop below freezing, and widens those cracks into channels. We’ve rebuilt crowns on homes near the Lynnfield Common where the original crown was nothing but Portland cement slopped on by the builder, already crumbling after fifty years. A proper rebuild uses a concrete mix with air entrainment for freeze resistance, sloped to shed water, with a drip edge that protects the brick below.
Crown Coating
Not every cracked crown needs a full tear-off. Crown coating with Gelco’s flexible sealant system is our go-to for Lynnfield chimneys where the crown is structurally sound but the surface is porous or lightly cracked. The coating bridges gaps up to 1/8 inch, remains flexible through temperature swings, and carries a ten-year warranty when applied to a properly prepared surface. It’s particularly cost-effective on the town’s 1960s multi-flue stacks where the crown is thick enough but the surface has weathered. Typical crown coating in Lynnfield runs $480-$650, compared to $720-$890 for a full rebuild.
Multi-Flue Cap
The multi-flue cap is the right solution for Lynnfield’s most common chimney configuration: the double or triple flue stack built to serve both fireplace and heating appliance. After the heating flue was abandoned, too many homeowners left it open or covered it inadequately. A multi-flue cap spans the entire chimney top, protecting all flues with a single unit that sheds water beyond the crown edge. We size these on-site with Copperfield and Olympia Chimney systems, accounting for flue height differences and clearance requirements. It’s the cleanest fix for the abandoned-boiler-flue problem our techs find weekly.
Custom Cap
Some Lynnfield chimneys need more than a catalog part. Oversized flues, unusual projections, or historic masonry details call for custom fabrication. We’ve built custom caps for extended chimney breasts on Georgians near the Upper Common and for homes where the flue spacing doesn’t match standard multi-flue units. Custom work runs $680-$1,200 depending on metal choice and complexity, with stainless steel as the practical standard and copper available for homeowners who want the look to last.

Common Chimney Cap & Crown Problems We See in Lynnfield Homes
- Abandoned boiler flues left open to weather. After oil-to-gas conversions, the old heating flue in a multi-flue stack often gets ignored. Rain enters, freeze-thaw splits the clay tiles, and squirrels or raccoons move into the warm chimney. A multi-flue cap or individual cap on the abandoned flue stops the damage.
- Generic caps on factory-built fireplaces. Zero-clearance fireplaces in 1980s-2000s Lynnfield homes require manufacturer-listed termination caps. Off-the-shelf hardware store caps don’t fit correctly, can overheat, and may void the fireplace warranty. We match the spec.
- Crown cracks from aggressive freeze-thaw. Lynnfield’s inland location means sharper temperature swings than coastal towns. Wet snow followed by rapid thaw saturates the crown, overnight freezing expands the cracks, and by spring water is dripping into the smoke chamber.
- Rusted or missing caps after storms. Nor’easters with wind gusts off the Atlantic still pack enough punch inland to tear loose poorly installed caps. We anchor with stainless steel fasteners and proper counter-flashing, not sheet-metal screws into crumbling mortar.

FAQs - Chimney Cap & Crown in Lynnfield
Yes, both flues need proper termination. The abandoned boiler flue is especially vulnerable because it has no draft to push out intruding water or animals. We typically recommend a multi-flue cap that covers the entire chimney top, protecting both flues with a single unit that sheds water beyond the crown edge. Call (857) 364-8219 and we’ll size it on-site - estimates are free.
A crown coating works when the crown is structurally sound - no sagging, no loose chunks, cracks under 1/8 inch - but the surface is porous or weathered. If the crown is crumbling, sloped toward the flues, or missing pieces at the edges, it needs a rebuild. We make that call with a Level 2 camera inspection and photos you can see for yourself. No recommendation without evidence. Call (857) 364-8219 to schedule.
No, and anyone who says otherwise is risking your safety. Factory-built fireplaces require manufacturer-listed termination caps with specific clearances and spark arrestor ratings. We match the original equipment specs using Olympia Chimney and Famco listed components, not generic masonry caps forced onto a metal flue. The wrong cap can overheat the chase or void your homeowner’s insurance. Call (857) 364-8219 for the correct part.
Yes. Even light creosote is combustible, and capping a flue traps any residual moisture that can accelerate deterioration of the clay tiles. We sweep abandoned flues before capping, then document the condition with camera photos. If the flue is damaged, we’ll show you and discuss whether relining or sealing is the better long-term fix. Call (857) 364-8219 to book the full service.
Annually, per NFPA 211 - and in Lynnfield’s climate, we think that’s the minimum, not the maximum. The combination of aging masonry, aggressive freeze-thaw, and abandoned flues means trouble can develop within a single heating season. Homes with multiple flues or recent fuel conversions benefit from inspection every year before burning season starts. Call (857) 364-8219 to get on the schedule.
Our tech was out on a 1965 colonial near Pillar Road where the original multi-flue stack still had the old oil boiler flue capped with nothing but a rusted sheet-metal plate, and the clay tiles had spalled badly from another inland Essex County freeze-thaw winter. We pulled the plate, ran a Level 2 inspection, found the abandoned flue fully open to animal entry, and finished the job with a custom multi-flue Copperfield cap sized to cover both the live fireplace flue and the dead boiler flue, plus a Gelco crown coating to seal the cracking mortar at the top of the stack. Photos of every step went to the homeowner before we packed up. Done right - and we stand behind it.
Lynnfield’s housing story is written in its chimneys. The 1950s-1970s colonial-revival boom means the town is full of multi-flue stacks - one flue for the fireplace, one for the oil boiler - so the furnace-to-high-efficiency-gas conversion wave left thousands of now-abandoned clay-tile flues open to weather, animals, and freeze-thaw damage. This pattern is distinctly different from coastal Essex County towns dominated by single-flue fireplace chimneys. A technician who doesn’t know Lynnfield might miss it entirely, slap a single cap on the live flue, and leave the homeowner with a slow-motion water problem overhead. We don’t miss it. We’ve seen it too many times.
