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.
HeatShield Chimney Cap & Crown in Olympia: What to Know First
We provide independent HeatShield chimney cap and crown service in Olympia, typically scheduling within three to five business days and delivering a written price before any work starts. Most HeatShield cap replacements and crown repairs run $280 to $890 depending on flue count, access, and whether the crown needs coating or full rebuild. As an independent HeatShield service provider, we source OEM and quality aftermarket parts through our Haven buying network and warranty our workmanship under the Haven Standard.
This page is for Olympia homeowners who know they’ve got HeatShield components on their chimney and want to understand what fails, what it costs, and who can fix it without the runaround. Call (360) 464-2015 for a free estimate.
How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Foam liner systems with cracked or spalling crowns. The foam liner shrinks and expands with every burn cycle, and that movement transfers stress to the crown above it. We see this especially on the older 2000-series jobs in the South Sound where the original crown was poured thin. We cut back to sound concrete, apply a bonded crown coat rated for the liner’s expansion profile, and reflash with a cap sized to the new crown dimensions.
- HeatShield UL 1777-listed caps with corroded mesh on salt-air exposures. The standard 304 stainless mesh holds up fine inland, but homes near Budd Inlet or along the Eld Inlet get pitting corrosion in the 18-month window. We stock 316 marine-grade mesh replacements through our Olympia Chimney supply line and can swap the mesh without replacing the full cap frame if the frame geometry is still true.
- Multi-flue HeatShield caps with improper throat spacing. The MF-series caps need exact centering over each flue tile; installers who eyeball it create drafting problems and creosote staining on the chase. We measure with a laser square, order the cap to those exact offsets, and document the throat clearances on the photo record.
- HeatShield crown coating delamination after freeze-thaw cycles. Olympia’s 30 to 40 annual freeze-thaw cycles (per NOAA data for the 98501 zip) push water into hairline cracks, then jack them open. The factory crown coat is cementitious and can’t flex. We strip to substrate, apply a modified polymer crown coat with a 3/8-inch minimum thickness, and slope it 1/4-inch per foot to shed water toward the drip edge.
- Custom-fabricated HeatShield caps with failing chase covers on prefab chimneys. The CF-series custom caps are built to order, but the chase cover beneath them is often galvanized steel that rusts through in 7 to 10 years in our climate. We fabricate replacement chase covers in 24-gauge stainless with cross-breaks to prevent oil-canning, then mount the existing HeatShield cap or spec a new one if the original is no longer weather-tight.
Our HeatShield Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers. We ask for the HeatShield model or series if you know it, the chimney configuration (single flue, multi-flue, prefab), and any symptoms you’ve noticed. We book a two-hour arrival window.
- 2
NFPA 211 Level 2 inspection with camera. The camera goes in first. Everything else follows from what it finds. We scan the flue, crown, and cap interior, then photograph the exterior from roof level. You get the footage and stills on the spot.
- 3
Written scope and price. Before any tool comes off the truck, we deliver a written price, written scope, and written warranty. Clause 1 of the Haven Standard - have it in writing. No exceptions.
- 4
Parts decision: OEM or quality aftermarket. For current HeatShield lines, we can source factory caps and crown coating through our buying network. For discontinued series, we match specifications with Gelco or DuraFlex equivalents that don’t compromise the system. You see the part numbers before we order.
- 5
Repair and test. We execute the cap install, crown rebuild, or coating application, then run a draft test and visual scan to confirm clearances and weather-tightness.
- 6
Documented record and Done Right Promise. Photos, measurements, and warranty terms are uploaded to your record. Clause 4 of the Haven Standard requires this archive. The 365-Day Done Right Promise covers our workmanship.

Why Olympia Homeowners Call Level Two Chimney Olympia for HeatShield Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of the South Sound inventory runs HeatShield liners and caps from the 2010s install wave. Corrine Halstead and our crew know the difference between a Series 2000 foam job and a UL 1777-listed cap install - and we know which parts are still available factory-direct versus which need a cross-reference to Gelco or DuraFlex.
Our technicians are background-checked, uniformed, and named before they arrive. You get a text when they’re en route. The license number is on the page and on the truck. Every job carries the 365-Day Done Right Promise, and if you’ve got a competitor’s written estimate, we’ll give you a free second opinion.
We don’t sell fear. We document what we find, name the price, and let you decide what to fix and when.
FAQs
HeatShield’s liner warranty covers the Cerfractory Foam product itself, not the cap or crown above it unless those were part of an original system package. Cap and crown issues fall under installation workmanship or material wear, which is why we warranty our repair work independently under the Haven Standard’s 365-Day Done Right Promise. For warranty questions on your specific install date and series, call (360) 464-2015 and we’ll pull the records.
Some MF-series and early CF-series caps are discontinued, but we cross-reference dimensions to quality aftermarket equivalents from Gelco and DuraFlex that maintain proper throat clearances and spark arrestor ratings. We never install a cap that doesn’t match the flue specification - that’s a fire hazard and a code violation in Olympia.
Coating works when the crown has surface cracking or minor spalling but the structural slab is intact with no exposed rebar. Full rebuild is needed when the crown is cracked through, separating from the flue tile, or the steel reinforcement is rusting and expanding. Our camera and roof inspection tell the difference - we show you the photos and explain which category you’re in before pricing either option.
Sometimes, but not always. A cap with the wrong throat clearance or a blocked mesh can restrict draft, but so can a partially blocked flue, negative pressure in a tight house, or improper firebox-to-flue sizing. We test draft before and after cap work so you know whether the fix worked or whether the problem is deeper in the system.
Most cap replacements are done in two to four hours. Crown coating needs a full day for prep, application, and cure time before the cap goes back on. Full crown rebuilds run one to two days depending on formwork and weather. We give you the schedule in writing with the price - no surprises.
