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 Wilmington: What to Know First
We provide independent Olympia Chimney chimney cap & crown service in Wilmington, from standard cap swaps to full crown rebuilds on multi-flue systems. Most Olympia Chimney jobs run same-week once we complete the camera inspection, and every repair starts with a written price before anyone touches your flue. If you own an Olympia Chimney cap or crown in Wilmington and you’re seeing rust streaks, water in the firebox, or mortar crumbs on the hearth, call (610) 546-5053. We’ll get a technician out, run the camera, and hand you a written scope with the exact cost. No deposit, no pressure, no surprises.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney Gelco-style galvanized caps (GC series) - coastal rust-through. Wilmington’s salt air off the Delaware River accelerates corrosion on the GC-series galvanized shell, especially on homes within two miles of the waterfront. We see pinholes forming at the weld seams in 6-8 years, not the 15 the datasheet suggests. Our fix: pull the GC cap, assess the flue tile condition underneath, and install a 304 stainless replacement through our Haven buying network. The stainless unit costs more upfront, but we document the expected lifespan difference in writing.
- Olympia Chimney multi-flue caps - improper overhang on wide masonry. The MF-series ships with standard 2-inch overhang, which works on narrow flues but leaves the crown exposed on older Wilmington homes with 36-inch or wider chimney tops. Water hits the crown, freezes, and spalls the surface. We measure the full crown width, spec an extended-overhang cap or a custom fabricated unit, and show you the coverage difference on the photo record before ordering.
- Olympia Chimney crown coating failures - UV breakdown on south faces. The factory crown coating applied to Olympia Chimney pre-cast crowns degrades faster on south and west exposures in Wilmington’s summer sun. We find alligatoring and surface chalking by year 4, not year 10. Our fix: grind to sound concrete, apply a breathable silane-siloxane sealer, then topcoat with a crown-specific elastomeric. We photograph each layer so you have the build documented.
- Olympia Chimney wind-load cap separation - the 302 and 304 series. These lighter-gauge caps use a tension-band mount that loosens in sustained 40+ mph winds common to Wilmington’s spring storm season. The cap lifts, tilts, and sometimes departs entirely. We find them in yards or on roofs. Our fix: replace with a through-bolt mounted cap, or add a stainless cable tether system where the flue configuration allows. We torque to spec and photo the attachment.
- Olympia Chimney flue stretcher caps - creosote bridging on slow-burning inserts. The FSC series with built-in wind-beating flue stretchers work well on open fireplaces but can accumulate heavy creosote deposits at the reduced throat opening when paired with EPA-certified inserts. In Wilmington’s Brandywine neighborhood, where homeowners burn compressed logs for long cycles, we’ve pulled caps with 1/4-inch glaze deposits choking the draft. Our fix: remove the cap, mechanical clean the stretcher vanes, and recommend a cap with greater free-air area if the insert is staying.
Our Olympia Chimney Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers, checks availability in Wilmington, and books your inspection. You get a text when your technician is en route.
- 2
NFPA 211 Level 2 camera inspection. We run the camera down the flue, photograph the crown from the roof, and document cap attachment points. Clause 4 of the Haven Standard requires this photo record on every job, and we’ve done it since 2009.
- 3
Written price and scope. Before any work starts, you receive a written price, a written scope of work, and a written warranty. Haven Standard Clause 1 - have it in writing. No exceptions.
- 4
Parts decision: OEM Olympia Chimney or quality aftermarket. We stock common Olympia Chimney caps through our Haven buying network. If your model is discontinued or the lead time exceeds your comfort, we source equivalent 304 stainless from Famco or Copperfield and show you the spec sheet comparison. You choose.
- 5
Repair and test. We install to manufacturer torque specs, verify draft with a manometer reading, and water-test crown repairs with a controlled spray. The technician photographs every critical step.
- 6
Cleanup and documentation. You receive the complete photo record, the final invoice matching the written price, and the 365-Day Done Right Promise stamped on your paperwork. Here’s what the camera found. Here’s what it costs to fix it. You decide.

Why Wilmington Homeowners Call Emberly Chimney Cleaners Wilmington for Olympia Chimney Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of our Wilmington calls involve Olympia Chimney products installed in the 2015-2020 window. Corrine Halstead and our crew know the difference between a GC-series pinhole leak and an MF-series overhang problem before we leave the truck, because we’ve documented both failure modes dozens of times in this market.
Our technicians are background-checked, uniformed, and carry license information on every page of every invoice. The 365-Day Done Right Promise covers every cap and crown job. If the coating cracks, the cap loosens, or the seal fails, we make it right. No argument, no re-dispatch fee.
We also service DuraFlex, HeatShield, and Gelco systems, so if your Olympia Chimney repair reveals a liner or smoke chamber issue, we don’t hand you off to another contractor. One crew, one written price, one documented record.
FAQs
No. As an independent Olympia Chimney service provider, we use OEM or equivalent parts and document the work to manufacturer spec. The warranty covers defects in materials and workmanship, not who performed the installation. We keep our photo records for 7 years in case a claim arises. Call (610) 546-5053 if you need documentation for a warranty submission.
Most single-flue cap replacements finish in 90 minutes to 2 hours, including the camera inspection and draft test. Multi-flue caps or jobs requiring crown repair add 2-4 hours. We book by the job, not the hour, so the written price doesn’t change if access is tighter than expected. Call (610) 546-5053 to check this week’s availability.
We repair crowns when the damage is superficial - surface spalling, hairline cracks, or coating failure over sound concrete. We rebuild when cracks penetrate to the flue tile, rebar is exposed and rusting, or the crown has separated from the brick course. The camera inspection and tap test tell us which category you’re in, and we show you the photos before quoting either option. Call (610) 546-5053 for a free assessment.
OEM caps fit without modification and match the original spec, which matters for warranty claims and resale documentation. Aftermarket caps from Famco or Copperfield often use heavier-gauge stainless at a lower price point, and we can fabricate custom fits for non-standard flue sizes. We stock both, explain the trade-offs, and let you choose based on your budget and how long you plan to own the home. Call (610) 546-5053 to see samples.
Water enters the flue system, freezes in winter, and expands cracks in the flue liner and surrounding brick. In Wilmington’s climate, we’ve seen minor crown cracks become full liner failures in two heating seasons. Carbon monoxide risk rises if the liner deteriorates enough to leak flue gases into wall cavities. The repair cost typically doubles or triples. A camera inspection costs nothing and tells you whether you have months or seasons. Call (610) 546-5053 to schedule.
