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.
Olympia Chimney Chimney Cap & Crown in Bellevue: What to Know First
We provide independent Olympia Chimney chimney cap and crown service in Bellevue, typically scheduling within 3-5 business days and completing most jobs in a single visit. A written price arrives before any work starts, and every job includes a camera-scan inspection with a documented photo record. Most Bellevue homeowners with Olympia Chimney caps or crowns are looking at $280-$890 depending on whether we’re sealing a hairline crack or replacing a multi-flue cap assembly.
This page is for you if your home has an Olympia Chimney cap or crown and you’re seeing rust streaks, masonry spalling, or water in the firebox. We work on the Olympia Chimney 304 stainless series, the galvanized multi-flue units common in Bellevue’s 1990s construction, and the masonry crowns poured over their flue tile systems. Corrine Halstead and our crew have handled these exact setups across the Eastside, from the split-levels near Lake Hills to the custom builds in Somerset.
Call (425) 696-0387 for a free estimate. We’ll send a written price before anyone picks up a trowel.
How Olympia Chimney Products Fail - and How We Fix Them
- 304 stainless single-flue cap lid fatigue. The Olympia Chimney 304 series uses a 24-gauge lid that can oil-can (flex and crack at the center weld) after 8-12 winters in Bellevue’s freeze-thaw cycle. We see this most in the Lakemont and Cougar Mountain areas where elevation drives harder frost. Our fix: lid replacement with a heavier 22-gauge aftermarket equivalent, or full cap swap if the mesh skirt has degraded. We match the flue diameter precisely, Olympia Chimney’s 8″ round or 13×13 square being the most common here.
- Galvanized multi-flue cap corner rust-through. The Olympia Chimney galvanized multi-flue caps installed on many Bellevue townhomes from 1995-2010 carry a 20-year coating warranty, but the spot-welded corners pool condensation and fail first. The telltale is orange streaking down the chimney face, not from the flue but from the cap skirt itself. We replace with a powder-coated or stainless upgrade, or source direct-fit Olympia Chimney replacement lids if the frame is sound.
- Crown wash separation from Olympia Chimney flue tile. Olympia Chimney’s poured crowns use a sloped wash that terminates at the flue tile with a 1-inch overlap. In Bellevue’s wet winters, thermal cycling opens a gap there, and water follows the tile down into the smoke chamber. We cut back to sound concrete, re-pour with a bonded crown mix, and install a drip edge that sheds water clear of the tile. The camera goes down before and after to confirm the seal.
- Mesh screen clog on high-efficiency installs. Olympia Chimney caps with 5/8-inch mesh were spec’d for open wood-burning flues. When homeowners later install gas inserts with lower exhaust temperatures, condensation plus particulate mats the screen and chokes draft. We’ve pulled screens in Bellevue’s Bridle Trails neighborhood that were 70% blocked after one heating season. Our fix: swap to a 3/4-inch mesh cap rated for the appliance, or add a draft-inducer if the liner size demands it.
- Spalling concrete crown with exposed Olympia Chimney rebar. Older Olympia Chimney crowns in Bellevue’s pre-1985 stock were poured with standard concrete, not a freeze-thaw rated mix. Spalling lifts the surface, exposes the wire, and the wire rusts. Once rust jacking starts, the crown is structurally compromised. We strip to the block course, install a bonded wire mesh, and pour a new crown with a proper overhang and kerf. The Haven Standard Clause 4 photo record shows the rebar condition before we cover it.
Our Olympia Chimney Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers. We book a 2-hour window, send a tech photo and license number, and text when they’re en route.
- 2
Level 2 inspection with camera. We run the camera down the flue to check for hidden water damage, liner displacement, or creosote buildup that would change the scope. The camera doesn’t guess. Neither do I.
- 3
Written price, written scope. Before any work starts, you get a fixed price, a description of parts (OEM Olympia Chimney or equivalent from our Haven buying network), and the warranty terms. Clause 1 of the Haven Standard requires it in writing.
- 4
The repair. Cap jobs: remove old unit, verify flue opening, install with stainless fasteners and high-temp sealant. Crown jobs: grind back spalled concrete, apply bonding agent, pour and slope new crown, cure with moisture retention. Multi-flue assemblies get level-checked across all flues.
- 5
Post-work camera verification and documentation. Camera goes down again to confirm no debris entered the flue, no liner damage occurred. Photos, scope summary, and warranty document are emailed same day. Clause 4 of the Haven Standard requires the photo record; we’ve done this on every job since 2009.
- 6
Cleanup and follow-up. We haul old material. The 365-Day Done Right Promise is stamped on your invoice. If something’s not right, we make it right.

Why Bellevue Homeowners Call Level Two Chimney Bellevue for Olympia Chimney Work

We’ve completed more than 38,000 chimney inspections and cleanings since 2009, every one with a written price before work started and a documented record when done. That practice became Clause 4 of the Haven Standard because we were already doing it.
Our techs know Olympia Chimney’s product line from hands-on work, not a catalog. We also stock DuraFlex, HeatShield, and Gelco materials through our Haven buying network, so if an Olympia Chimney part is back-ordered or a better-fit solution exists, we can source it without delaying your job. Background-checked, uniformed crews. License number on every page. Live phone support, 24 hours a day.
The 365-Day Done Right Promise covers every cap and crown job we touch. And if another company already gave you a written estimate, we’ll review it free under our Second Opinion policy.
FAQs
No. As an independent Olympia Chimney service provider, we use OEM or equivalent-spec parts and document our work. Manufacturer warranties on materials typically cover defects in the product itself, not who installed it. We keep purchase records and install per manufacturer specs. If you have a specific warranty concern, bring us the paperwork and we’ll review it before we start.
Most common Olympia Chimney caps and hardware are available through our Haven buying network within 2-3 business days. For less common sizes, we often have compatible equivalents from DuraFlex, Gelco, or Famco in stock that meet or exceed OEM spec. We confirm parts availability when we write your estimate, not after we’ve started.
Hairline surface cracks with no spalling and sound concrete underneath usually qualify for sealant or coating. Once you see pieces flaking off, rust staining, or exposed metal, the crown is structurally compromised and needs removal and re-pour. Our camera inspection and hammer test during the estimate tell us which category you’re in. We’ll show you the photos and explain before you decide.
Water enters the chimney system, degrades the flue liner, rusts the damper, and can reach the firebox framing. In Bellevue’s climate, that damage accelerates from October through April. Carbon monoxide risk rises if liner degradation creates gaps. Chimney fire risk increases if water mixes with creosote to form acidic compounds that eat the liner. The repair you skip today typically costs 3-4x more in two years. Call (425) 696-0387 and we’ll give you an honest timeline for how long your specific crown or cap can safely wait.
Not automatically. Cap and crown failures don’t always damage the liner. We run the camera to check. If the liner is sound, we fix the cap or crown and you’re done. If we find liner damage, we show you the footage, explain the severity, and quote liner work separately. Nothing is recommended without camera evidence you can see for yourself. Call (425) 696-0387 for a free estimate.
