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.

How HeatShield Products Fail - and How We Fix Them
HeatShield builds solid products, but Kirkland’s wet winters and freeze-thaw cycles expose specific weak points we’ve tracked across thousands of local inspections. Here’s what we find on HeatShield systems:
- HeatShield UL Listed Caps (HS-UL series): The mesh screen on these caps traps moisture against the flue collar during our prolonged Pacific Northwest drizzles. In Kirkland’s Finn Hill and Norkirk neighborhoods, we regularly see the 304 stainless mesh corrode at the weld points within 6-8 years, not the 15-year span the specs suggest. We replace with marine-grade 316L mesh or source direct-fit OEM collars when the flue tile hasn’t degraded.
- HeatShield Multi-Flue Caps (HS-MF line): The universal base rail on these caps relies on a compression fit against the crown. When the crown develops hairline cracks from freeze-thaw, the rail loosens and the cap tilts, channeling water directly into the flue gap. We crown-coat first with HeatShield’s own CrownCoat or a compatible elastomeric, then reset the cap with stainless wedge anchors rather than the original tapcons.
- HeatShield CrownCoat applications (previous contractor jobs): We’ve found CrownCoat applied too thin in cold weather, which is common with fall rush jobs around Kirkland. The product cures to a chalky, permeable film instead of the specified flexible membrane, and water penetrates within two seasons. We strip to sound concrete, reapply at 1/8″ minimum wet thickness, and document the mil gauge with photos.
- HeatShield Gel-Coated Caps (discontinued HS-GC series): These show up in 2012-2018 builds around Totem Lake. The gel coat UV-degrades faster in south-facing exposures, and the underlying fiberglass delaminates. No OEM replacement exists, so we fabricate custom aluminum caps to the exact flue profile or adapt a Gelco multi-flue with a transition base.
- HeatShield Spark Arrestor Caps (HS-SA models): The arrestor mesh on these packs tight with creosote flakes during shoulder-season burning in Kirkland’s older homes. The resulting backdraft pulls smoke into the firebox. We clean the mesh in place when possible, replace the arrestor insert when it’s warped from overheating, and always check the flue for Class III glazed creosote that caused the overheating in the first place.
Our HeatShield Chimney Cap & Crown Process

- 1
Camera-scan diagnosis: We run an NFPA 211 Level 2 inspection with a chimney camera before touching the cap or crown. Clause 4 of the Haven Standard requires it, and it shows us whether the crown damage is cosmetic or if water has reached the flue liner.
- 2
Parts decision: For current HeatShield lines, we quote OEM parts through our Haven buying network. For discontinued series, we source compatible DuraFlex or Gelco components and flag any warranty implications in writing.
- 3
Written scope and price: You get a line-item document: labor, materials, disposal, warranty terms. No work starts until you approve it. That’s Haven Standard Clause 1.
- 4
The repair: Crown work gets stripped to sound concrete, primed with HeatShield-compatible bonding agent, and coated or rebuilt. Cap installs get stainless hardware, silicone seal at the flue interface, and a water-test with the hose.
- 5
Documentation and walkthrough: We deliver dated photos, camera footage, and a written completion record. The camera doesn’t lie, and neither does the invoice.
- 6
365-Day Done Right follow-up: If the cap shifts or the crown coating checks, we return and make it right. No charge. No argument.

| HeatShield cap installation (single flue, OEM) | $340-$580 | Flue height, need for extended base, steep roof access |
| HeatShield cap replacement (discontinued series, custom) | $520-$890 | Fabrication time, adapter plates, multi-flue configuration |
| Crown repair with HeatShield CrownCoat | $480-$760 | Crown square footage, crack depth, need for mesh reinforcement |

| Multi-flue cap (HeatShield or compatible) | $680-$1,150 | Flue spacing, chase top dimensions, wind load rating |
Steep pitches on Kirkland’s hillside homes, moss-heavy conditions near Juanita Beach, and chase tops over 28″ wide all add labor. We price these in writing before booking, not after arrival. Call (425) 642-3485 for an exact quote - estimates are free.
Why Kirkland Homeowners Call Level Two Chimney Kirkland for HeatShield Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share run HeatShield components from the 2010s building boom around Kirkland. Corrine Halstead and our crew know which series were spec’d on which builders, what fails first in our climate, and where to source parts without the markup of a factory-authorized chain. Our Haven Standard means background-checked techs in uniform, license number on every page, a text when we’re en route, and a documented photo record you can forward to your insurer or home buyer. We also stock DuraFlex and Gelco alternatives when HeatShield lines are backordered, so you’re not waiting six weeks for a cap while water enters the flue.
FAQs
No - as an independent HeatShield service provider, we use OEM-specified materials and documented procedures that preserve any remaining manufacturer coverage. We note your product serial number and install date on every invoice so warranty claims stay clean. If you’re unsure about your warranty status, call (425) 642-3485 and we’ll check it against your paperwork.
A properly applied CrownCoat repair lasts 10-15 years here if the underlying concrete is sound; a full rebuild goes 20-30. The key is our freeze-thaw prep - we don’t coat over saturated concrete, which is why we schedule crown work during dry windows and cover the chase if rain threatens. Call (425) 642-3485 for an exact quote - estimates are free.
We can match most discontinued HeatShield profiles with custom-fabricated aluminum or adapted Gelco multi-flue bases. Full chase-top replacement is only necessary when the existing top is rotted, improperly sloped, or structurally compromised. We determine this with a camera scan and photo documentation, not a ladder glance.
Every 12 months, per NFPA 211, and sooner if you notice rust staining on the chase, a tilted cap, or debris in the firebox. Kirkland’s Douglas fir and cedar burning deposits more creosote than owners expect, and that load stresses cap mesh and spark arrestors faster than all-gas usage. Call (425) 642-3485 to schedule - estimates are free.
Water enters the crack, freezes, expands the concrete, and opens a path to the flue liner. In Kirkland, that cycle runs October through April. We’ve replaced liners in Houghton homes where a $600 crown coat would have prevented $4,200 in flue work. We photograph the crack progression so you can see whether it’s stable or accelerating, and we tell you plainly when work can safely wait.
