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’ve been dispatching crews to Lynn from our Boston office for decades, and we know the city’s chimneys well. The triple-deckers along Willow Street, the two-families near Lynn Common, the older stock up toward Wyoma Square - we’ve capped and crowned them all. Russell Haines built this company on the principle that a homeowner should see the problem before paying to fix it, and that hasn’t changed in 42 years.
Lynn’s harbor exposure creates a specific kind of chimney damage you won’t find in Peabody or Danvers. Salt-laden air corrodes metal components and attacks mortar joints year-round, not just in winter. If you own a pre-1930 home here, your cap and crown are working harder than inland equivalents.

We answer our phones with a live person, 24 hours a day, every day. Not a callback queue, not an app. When a Lynn homeowner calls at 7 PM on a Sunday because water is coming through the ceiling around the chimney, someone picks up and schedules the inspection.

Our Chimney Cap & Crown Services in Lynn
Cap Installation
New cap installation in Lynn demands stainless steel, not galvanized, because of harbor salt exposure. A properly sized cap keeps rain, animals, and debris out of the flue while allowing proper draft. For triple-deckers along streets like Ocean Avenue or Neptune Boulevard, we often install multi-flue caps that protect several flues from a single chimney stack. We measure on-site, fabricate to fit, and install with stainless hardware that won’t corrode at the seams.
Cap Replacement
This is our most common call in Lynn. The original galvanized caps installed decades ago have simply corroded through. We were called to a triple-decker on Willow Street where the tenant in the top unit reported a drafty fireplace and water stains on the ceiling. Our tech found the original galvanized cap had corroded through at the seams, allowing water to run down the flue and rust the damper. We replaced it with a custom stainless steel multi-flue cap from Copperfield and sealed the crown with HeatShield, solving both the leak and the draft issue.
Cap replacement in Lynn runs $280-$550 for standard single-flue stainless caps, $650-$1,200 for custom multi-flue units on triple-deckers. We remove the old cap, inspect the flue opening for damage, and install the new unit with proper clearance and secure fastening.
Crown Repair
The crown is the concrete or mortar slab that seals the top of your chimney, and in Lynn it takes a beating. Salt air penetrates micro-cracks, then winter freeze-thaw cycles expand those cracks and spall the surface. Once water gets past the crown, it soaks into the brick structure, freezes, and pushes the masonry apart.
Crown repair in Lynn typically costs $350-$650. We grind out damaged material, apply a proper bonding agent, and pour new high-strength crown mix with a built-in slope to shed water. For crowns with minor cracking but solid structure, we may recommend crown coating instead.
Crown Coating
Crown coating is a preventive treatment for crowns that are sound but showing early surface deterioration. We apply HeatShield, a professional-grade elastomeric compound that seals hairline cracks and creates a waterproof, flexible membrane over the existing crown. At $280-$450, it’s roughly half the cost of full crown repair and can add years of service life if applied before structural damage sets in.
In Lynn’s salt-air environment, we recommend crown coating as part of a regular maintenance cycle, not a one-time fix. The coating should be inspected annually and touched up as needed.

Trusted Brands We Service in Lynn
We stock caps, crowns, and repair materials from Gelco, Olympia Chimney, and Copperfield on our Lynn-area trucks. These are professional-grade products, not builder-grade substitutes. Gelco’s stainless caps carry a lifetime warranty against corrosion, which matters on Ocean Avenue. Olympia Chimney’s multi-flue caps fit the oversized chimney stacks common in Lynn’s triple-deckers. Copperfield fabricates custom caps for odd-sized flues we encounter in 1890s worker housing.
Because we carry inventory locally, most Lynn jobs don’t wait for parts. We measure, fabricate if needed, and install in one trip.
Common Chimney Cap & Crown Problems We See in Lynn Homes
- Galvanized caps corrode through at the seams. Lynn’s salt-laden harbor air attacks galvanized steel aggressively. We regularly find caps with holes rusted completely through the top panel or along the mesh sides, allowing direct water entry into the flue.
- Original mortar crowns crack and spall from salt attack. The same salt that corrodes metal chemically degrades mortar. Combined with freeze-thaw cycling, this turns a sound crown into a porous, cracked surface that funnels water into the chimney structure.
- Flashing corrodes and pulls away after nor’easters. Pressurized wind-driven rain forces moisture into any gap between flashing and chimney. In Lynn, we’ve seen flashing that looked intact in October fail completely by March after repeated storm exposure.
- Multi-flue chimneys lack proper caps on all flues. Lynn’s triple-deckers often have three flues but only one capped, or a cap sized for one flue improvisationally stretched across two. This leaves gaps where water and animals enter, and can create draft problems between connected units.

What moves the price: accessibility (steep roof, height), flue size and count, extent of hidden damage found during removal, and whether the chimney requires scaffolding. We give you the full number before any work begins. The estimate is free, and the number on the estimate is the number on the invoice.
Lynn’s coastal exposure means we see more advanced corrosion than inland towns, which sometimes reveals additional damage once the old cap comes off. We photograph everything and explain what we found before proceeding. Work that can safely wait, we say so plainly.

FAQs - Chimney Cap & Crown in Lynn
Annual inspection is the minimum for Lynn chimneys, and we recommend checking caps specifically every fall before burning season. Salt air accelerates corrosion significantly compared to inland Essex County towns - a galvanized cap that might last 10 years in Peabody can fail in 4-5 years on a Lynn harbor-facing roof. Call (857) 364-8219 to schedule - estimates are free.
Yes, multi-flue caps are a standard part of our work in Lynn’s triple-deckers and two-families. We measure all flue openings, verify each is properly lined and venting only one appliance per Massachusetts 527 CMR fire code, then fabricate a stainless cap that covers the full chimney top with individual screened compartments. Call (857) 364-8219 for an exact quote - estimates are free.
Crown repair removes damaged material and rebuilds the crown structure; crown coating seals a structurally sound crown against future water penetration. Repair is needed when the crown has cracks wider than hairline, significant spalling, or exposed aggregate. Coating with HeatShield works for early-stage deterioration and costs roughly half as much. We determine which you need through camera inspection and photos you can see yourself. Call (857) 364-8219 for an assessment - estimates are free.
A corroded cap itself does not cause chimney fires, but the water infiltration it allows creates conditions that do. Water rusts metal dampers, damages liners, and mixes with creosote to form acidic compounds that degrade flue walls. A compromised flue can then allow heat transfer to combustible framing. The cap is your first line of defense. We inspect the full system when we replace a failed cap. Call (857) 364-8219 - estimates are free.
Yes, custom fabrication is often necessary for Lynn’s pre-1930 housing stock. Original flues in worker housing were built to coal-stove dimensions that don’t match modern standard cap sizes. We measure on-site and fabricate stainless caps from Copperfield or Olympia Chimney to exact specifications, typically within $650-$1,200 depending on complexity. Call (857) 364-8219 for an exact quote - estimates are free.
