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.
Gelco Chimney Cap & Crown in Olympia: What to Know First
We provide independent Gelco chimney cap and crown service in Olympia, from cap replacement on the Multi-Flue series to crown coating on aging Pre-Vent models. Most Gelco jobs run one to two hours, and you’ll get a written price before we start, not after we’re on your roof. As an independent Gelco service provider, we source parts through Haven’s buying network, which keeps customer prices honest without manufacturer markup.
This page is for Olympia homeowners who already own a Gelco cap or crown and need someone who knows the line, not a generic sweep who’ll guess at the part number. Call (360) 464-2015 for a free estimate. Corrine Halstead and our crew cover Olympia and the surrounding area, including the neighborhoods near the Capitol Campus and out toward Tumwater and Lacey.
How Gelco Products Fail - and How We Fix Them
- Multi-Flue cap lid separation. The Multi-Flue series uses a lid-over-base design that collects condensation where the two pieces meet. In Olympia’s wet winters, that moisture freezes, expands, and pops the lid seam. We see this most often on homes near Budd Inlet where the marine layer sits heavy. Our fix: remove the lid, reseal with high-temp silicone rated for freeze-thaw cycles, or replace with a one-piece welded lid if the metal has fatigued.
- Pre-Vent crown coating chalking. Gelco’s Pre-Vent crowns shipped with an acrylic coating that degrades to a powdery white film after five to seven years of South Sound UV and acid rain. It looks cosmetic but exposes the concrete crown beneath to water intrusion. We grind off the failed coating and apply CrownCoat or a similar elastomeric, then document the crown thickness with photos before and after.
- Single-Flue mesh screen blowout. The factory mesh on early Single-Flue caps is 18-gauge galvanized, which rusts through faster in Olympia’s salt-air microclimates, especially west-facing roofs near Eld Inlet. We replace with 304 stainless mesh, which costs more upfront but outlasts the original by a decade.
- Chimney crown corner spalling behind Gelco caps. Gelco caps mount with tension screws or adhesive bases. If the crown underneath has already taken water damage, the cap installation torque cracks the spalled concrete. We catch this with a camera inspection of the crown surface before we quote, not after we’ve committed to a cap that won’t seat flat.
- Top-Mount damper cap motor housing corrosion. The Top-Mount series integrates a damper with the cap. The motor housing sits proud of the flue and collects needle debris from Olympia’s heavy Douglas fir and cedar canopy. Moisture + tannic acid = housing pitting that jams the damper. We strip the housing, treat the pitting, and reseal with a gasketed boot, or replace the motor assembly if the worm gear has seized.
Our Gelco Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers, 24/7. We ask for the Gelco model if you know it, the flue count, and the symptom you’re seeing. We book a window that works.
- 2
Camera inspection on arrival. The camera goes in first. Everything else follows from what it finds. We inspect the crown surface, flue top, and surrounding masonry for hidden damage that would make a new cap fail.
- 3
Written price, written scope. Before any ladder goes up, you get a paper with the part number or repair method, the labor line, and the total. Clause 1 of the Haven Standard: have it in writing.
- 4
Parts decision. We stock common Gelco-compatible caps and crowns through our Haven buying network. If your model is discontinued, we source a quality aftermarket fit from Olympia Chimney or Famco and tell you exactly what’s changing.
- 5
Install or repair, then test. Cap goes on with proper tension, crown gets coated to spec, or the damper motor gets cycled twenty times. We don’t leave until it operates clean.
- 6
Photo record and warranty. Clause 4 of the Haven Standard requires a photo record on every job. You get the images, the written warranty, and our 365-Day Done Right Promise before we pack up.

Why Olympia Homeowners Call Level Two Chimney Olympia for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a solid subset of those were Gelco caps in Olympia’s variable climate. Our techs know the difference between a Multi-Flue lid that needs resealing and one that’s fatigued beyond repair. When Gelco parts run long-lead, we pull from DuraFlex, HeatShield, or Olympia Chimney through our Haven buying network, so you’re not waiting three weeks for a mesh screen.
Corrine Halstead runs the operation with the same practice she learned in Queens and refined across the Northeast: photo, measurement, price, in that order. Every job gets a named technician, a text when they’re en route, and license information on the page. If something’s not done right, we make it right. That’s the 365-Day Done Right Promise, stamped on every job under the Haven Standard.
FAQs
Gelco’s original warranty on most caps covers manufacturing defects for one year from purchase; it does not cover labor or weather damage. As an independent Gelco service provider, our work carries its own 365-Day Done Right Promise under the Haven Standard, separate from any manufacturer coverage. Call (360) 464-2015 for an exact quote - estimates are free.
Yes. We source compatible caps and components through our Haven buying network from Olympia Chimney, Famco, and Copperfield. If your Pre-Vent or early Single-Flue model is discontinued, we match the flue dimensions and mount style and tell you exactly what’s changing before we order. Call (360) 464-2015 for an exact quote - estimates are free.
We determine that with a camera inspection of the crown surface and a sounding test for hollow spots. Surface crazing and minor spalling take coating; rebar exposure or through-cracks mean rebuild. You’ll see the photo before we write the price. Call (360) 464-2015 for an exact quote - estimates are free.
Most single-flue replacements run 45 minutes to 90 minutes on site. Multi-Flue or Top-Mount damper jobs run two to three hours if the crown is sound. If we find crown damage during inspection, we’ll show you and adjust the scope before any work starts. Call (360) 464-2015 for an exact quote - estimates are free.
Not usually. Cap failure and liner condition are separate issues, though a missing cap can accelerate liner deterioration by letting rain and debris enter the flue. We camera-scan the full flue on every cap job and tell you if the liner needs attention on its own merits. Call (360) 464-2015 for an exact quote - estimates are free.
