Fast, Reliable Chimney Cap & Crown Across Lynnwood
Chimney cap and crown repair in Lynnwood typically runs $340–$890 depending on whether we’re coating a cracked crown or installing a full custom cap, and most jobs are completed in a single visit. If you’re seeing water stains on your ceiling near the fireplace, crumbling mortar on your chimney top, or hearing animals in your flue, the crown or cap is likely compromised.

We’ve been climbing Lynnwood roofs since 2008. From the split-level ranches along Caspers Street to the original 1960s builds in Beverly Acres and the wooded lots off Larch Way, we know how this city’s older housing stock fails. Lynnwood’s position in unincorporated Snohomish County through much of its development meant inconsistent building oversight, so chimney construction quality varies block by block. That matters when we’re diagnosing crown damage or specifying a cap — what works on a 1975 Meadowdale home may be wrong for a 1962 Perrinville ranch. Our Chimney Cap & Crown team brings 17 years of chimney-only expertise to every Lynnwood job, and James Wilson arrives as lead technician, not a subcontractor you’ve never met.
Why Horizon Chimney Sweep Washington Is Lynnwood’s Preferred Chimney Cap & Crown Company
We’ve earned our reputation in Lynnwood one roof at a time. Over 1,006 verified customer reviews averaging 4.8 stars reflect repeated trust from homeowners who’ve called us back year after year — not a handful of curated testimonials from friends and family.
James Wilson is the technician who answers your questions and handles the inspection. When you schedule cap or crown work in Lynnwood, you’re getting 17 years of hands-on chimney expertise at your door, not a rotating crew of generalists. We’ve diagnosed crown failure on homes near the paper airplane sculptures off 3rd Avenue North, installed custom caps in North Lynnwood’s tighter lot configurations, and treated glazed creosote buildup from green Douglas fir in Meadowdale that would stump a multi-trade contractor.
Our response time to Lynnwood averages same-day to next-day for standard calls, and we stock parts from Famco, Copperfield, and DuraFlex so we’re not ordering caps while your chimney leaks. We understand how Lynnwood’s 37 inches of annual rainfall, freeze-thaw cycles, and older clay tile flue liners create cap and crown problems that differ from Edmonds or Mountlake Terrace just minutes away.
Our Chimney Cap & Crown Services in Lynnwood
Cap Installation
New cap installation in Lynnwood runs $280–$520 for standard single-flue galvanized or stainless steel units, and $650–$1,200 for custom copper or multi-flue configurations. Most Lynnwood homes we service — particularly the 1960s and 1970s ranches in Beverly Acres and Cedar Valley — were built with no cap at all, or with a rusted-through original that’s now letting rain and animals into the flue. We measure on-site and fabricate to fit, because chimney dimensions on these older homes weren’t standardized the way new construction is.
Cap Replacement
Cap replacement in Lynnwood typically costs $240–$480 when the flue and crown are sound. We see this need most often in North Lynnwood and Perrinville, where original caps have corroded after decades of salt-laden marine air or were damaged by falling branches from the mature Douglas fir and cedar stands that still dominate lots off Poplar Way. We remove the failed unit, inspect the crown beneath for hidden damage, and install a properly sized replacement with correct clearances for your fuel type.
Crown Repair
Crown repair is our most frequent call in Lynnwood, and it’s where local knowledge matters most. A typical crown rebuild runs $520–$780, while minor crack repair starts around $280. Lynnwood’s original masonry chimneys — common from Larch Way to Meadowdale — were built with mortar crowns that weren’t properly sloped or reinforced. Decades of Puget Sound moisture absorption, followed by winter freeze-thaw cycles, cause the concrete to spall and crack. Water pools. Moss colonizes. The crack widens. Eventually water reaches the clay tile liner below, accelerating deterioration that can require full liner replacement if caught too late.
Crown Coating
Crown coating with a flexible sealant like CrownSeal costs $340–$550 and extends the life of a structurally sound crown by 10–15 years. This is often the right choice for Lynnwood’s 1960s and 1970s homes where the crown is cracked but the underlying concrete hasn’t fully failed. We clean the surface, fill active cracks, and apply a waterproof membrane that moves with the chimney as it expands and contracts through freeze-thaw cycles. It’s not a substitute for a crown that’s crumbling — we’ll tell you honestly which category yours falls into.
Custom Cap
Custom caps in Lynnwood range from $680–$1,400 depending on material, size, and whether we’re covering multiple flues. We specify custom work when standard sizes won’t fit — common with the partially lined or improperly adapted flues we find in homes that converted from wood to gas and back. On a 1970s split-level in Cedar Valley, we found a cracked clay tile flue liner and a chimney crown that was spalling from freeze-thaw cycles. We coated the crown with CrownSeal and installed a custom copper multi-flue cap from Copperfield to prevent moisture entry and future damage. Custom fabrication also matters in Meadowdale, where steep roof pitches and mature tree canopy require specific mesh sizes and lid overhangs.
Multi-Flue Cap
Multi-flue caps protect two or more flues with a single hood, critical for Lynnwood’s older homes with separate fireplace and furnace flues. Installation runs $590–$980. These systems eliminate the gap between individual caps where water and debris collect, and they’re essential when flues are close together on a shared crown that’s already showing stress.

Trusted Brands We Service in Lynnwood
We install and repair using Famco, Copperfield, and DuraFlex components — brands that have proven themselves in Pacific Northwest conditions. We maintain local inventory of common cap sizes and crown coating materials, so Lynnwood homeowners aren’t waiting two weeks for a part while rainwater runs down their flue. For custom fabrications, we work with Copperfield’s specification system to ensure proper fit on non-standard chimney dimensions common to this city’s 1960s and 1970s housing stock. When we recommend a product, it’s because we’ve seen it perform on Lynnwood roofs through multiple winter cycles — not because it’s the cheapest option in a catalog.
Common Chimney Cap & Crown Problems We See in Lynnwood Homes
- Freeze-thaw spalling on original mortar crowns. Lynnwood’s persistent marine moisture penetrates crown concrete, then expands when temperatures drop below freezing overnight. The surface flakes off in layers, exposing the chimney interior to accelerated water damage. We see this most on unmodified 1960s and 1970s chimneys in Beverly Acres and North Lynnwood.
- Moss colonization and water pooling on flat or poorly sloped crowns. Original crowns on Lynnwood homes were often finished nearly level, lacking the minimum 2-inch overhang and proper slope that modern code requires. Moss holds moisture against the surface, accelerates deterioration, and can root into hairline cracks. This is a signature failure mode in shaded lots near Meadowdale’s second-growth timber stands.
- Improperly adapted flues from fuel-source changes creating crown gaps. Many Lynnwood homeowners converted wood fireplaces to gas inserts in the 1990s, then back to wood when gas prices spiked. Each conversion left liner adaptations, partial removals, or diameter changes that created gaps at the crown level. Water and debris enter these openings. Custom caps are often required to seal properly around the modified flue configuration.
- Third-degree glazed creosote from green local wood compromising cap function. In neighborhoods like Meadowdale and Lake Stickney, homeowners burn self-felled or neighbor-supplied Douglas fir and alder that hasn’t fully seasoned in the region’s damp air. This creates glazed creosote that requires chemical treatment before mechanical brushing — a step far less common in drier Eastern Washington markets. Heavy creosote buildup can obstruct flue draft, causing smoke and moisture to back up against the cap and accelerate corrosion.

What moves you within these ranges? Crown size and accessibility are the biggest factors — a two-story chimney on a steep Meadowdale roof takes longer than a single-story ranch in Beverly Acres. The extent of hidden damage we find once we’re on the roof also matters; a crown that looked repairable from the ground may need full replacement once we probe the surface. We inspect before quoting, and we don’t upsell — if coating will last five years, we’ll tell you. If it’s past saving, we’ll show you why. Call (866) 541-8697 for your free Lynnwood estimate.

FAQs — Chimney Cap & Crown in Lynnwood
Lynnwood receives roughly 37 inches of annual rainfall in a persistent marine pattern, with long grey winters that keep chimney crowns saturated for months. When temperatures drop below freezing overnight, absorbed water expands and fractures the concrete — a cycle that simply doesn’t occur in drier Eastern Washington climates. We see crown damage in Lynnwood homes at twice the rate we observe in counties east of the Cascades. Call (866) 541-8697 for a free inspection if your home is 40-plus years old.
We specify 5/8-inch spark arrestor mesh (required by most insurers for wood-burning installations), a minimum 4-inch lid overhang to shed heavy rain, and 304 stainless steel or copper construction to resist salt-laden marine air. Meadowdale’s mature tree canopy also warrants a taller lid profile to prevent leaf and needle accumulation that can block airflow. We fabricate custom to your flue dimensions after on-site measurement. Call (866) 541-8697 to schedule.
Lynnwood’s residential core was built primarily during the 1960s and 1970s suburban boom, when much of the area was unincorporated Snohomish County with less consistent building oversight than neighboring Edmonds or Mountlake Terrace. Original chimney construction quality varies widely block by block — some crowns were properly sloped and reinforced, others were finished flat with weak mortar mixes that failed predictably decades later. This inconsistency means every inspection requires hands-on evaluation, not assumptions based on construction year. James Wilson performs this assessment personally on every Lynnwood job.
Yes, if the concrete substrate is still structurally sound and cracks haven’t penetrated to the flue liner below. We test by sounding the surface and probing cracks — hollow areas or crumbling edges mean replacement, not coating. For Beverly Acres ranches with original crowns showing hairline to moderate cracking but solid base material, CrownSeal coating typically adds 10–15 years of service life at roughly half the cost of rebuild. We’ll show you what we find and give an honest recommendation. Call (866) 541-8697 for an exact assessment.
Missing or improperly sized caps on chimneys that were never fitted with one, or where an original rusted through decades ago. Lake Stickney’s wooded lots and frequent wind exposure from the nearby Snohomish River valley also mean debris accumulation and cap displacement from falling branches. We install properly secured caps with adequate mesh and overhang for these conditions. Call (866) 541-8697 — estimates are free, and we carry common sizes for same-day installation.
