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.

AfterGelco Chimney Repair in Pasadena: What to Know First
We provide independent Gelco chimney repair in Pasadena, typically completing most jobs within one to three business days after inspection. A written price arrives before any work starts, and every repair includes a camera-scan photo record under Clause 4 of the Haven Standard. This page is for Pasadena homeowners who own Gelco chimney components - caps, dampers, liners, or accessories - and need repair work done by technicians who understand how these products age in our local climate. Call (213) 459-6058 for a free estimate.
How Gelco Products Fail - and How We Fix Them
- Gelco chimney caps (Model A- and B-series) - The galvanized steel mesh on older A-series caps corrodes faster than owners expect, especially within three miles of the 210 freeway where Pasadena’s winter inversion traps moisture and road salts against metal. We see the mesh detach at the weld points first. Our fix: replace with a Gelco-compatible 304 stainless mesh insert or, if the base is compromised, fit a new cap from our Haven buying network with a lifetime rust warranty.
- Gelco top-mount dampers (Pre-2015 cast-aluminum frames) - The cast-aluminum frames on early top-mount dampers develop stress cracks at the hinge boss after repeated thermal cycling. Pasadena’s dry summers don’t help; the aluminum expands and contracts more aggressively than the surrounding masonry allows. We replace the frame with a current Gelco-spec stainless hinge assembly or, when the flue throat is damaged, retrofit a HeatShield-compatible damper system.
- Gelco flue liners (Type 316Ti corrugated) - The corrugated profile traps condensate in shoulder seasons when Pasadena homeowners run short evening fires. That trapped moisture, combined with our occasional Santa Ana wind pressure events, accelerates pitting at the corrugation valleys. We camera-scan to map the pitting depth, then either spot-repair with a DuraFlex liner section or recommend full replacement if pitting exceeds 30 percent of wall thickness.
- Gelco chimney crowns with integrated drip edges - The factory-poured crowns ship with a shallow slope that doesn’t shed water fast enough during Pasadena’s brief but intense winter rains. Water backs up at the drip edge, freezes on the rare sub-32 night, and spalls the crown surface within four to six years. We grind back to sound concrete, repitch to a minimum 3/12 slope, and seal with a breathable siloxane compatible with Gelco’s original mix design.
- Gelco spark arrestor screens (multi-flue models) - The multi-flue arrestors use a lighter-gauge mesh than single-flue units, and Pasadena’s eucalyptus leaf litter (common in the San Rafael Hills and Linda Vista areas) packs against the screen, creating a reverse-draft condition that draws smoke into second-floor bedrooms. We clean and reset the screen, or upgrade to a heavier mesh with a wider grid pattern that sheds debris without violating California’s wildfire code.
Our Gelco Chimney Repair Process
- 1
Call and schedule. A live person answers, 24/7. We book a two-hour window and text when the tech is en route.
- 2
NFPA 211 Level 2 inspection. Camera down the flue, photos of every Gelco component, readings on liner condition and clearance. Corrine Halstead reviews the footage with you before quoting anything. The camera doesn’t negotiate - it just shows what’s there.
- 3
Written price and scope. We specify OEM Gelco parts versus quality aftermarket alternatives from our Haven buying network, with the trade-offs named plainly. No work starts until you have the written price in hand.
- 4
Repair and test. Techs complete the repair, run a draft test, and verify damper operation across the full temperature range.
- 5
Photo record and warranty. Clause 4 of the Haven Standard requires a documented photo record on every job. You receive it by email, along with the written warranty and the 365-Day Done Right Promise.

Why Pasadena Homeowners Call Emberly Chimney Cleaners Pasadena for Gelco Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those were Gelco products in Pasadena’s 1910-to-1940 housing stock. Corrine Halstead and her crew know the difference between a Gelco A-series cap that can be saved and one that’s past its weld life. When Gelco OEM parts run long-lead, we source equivalent-grade stainless through our Haven buying network from DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield - same spec, honest price, no markup theatre. Every tech is background-checked, uniformed, and arrives with license information displayed. The 365-Day Done Right Promise covers every repair: if it’s not done right, we make it right.
FAQs
No, if the repair is performed correctly using compatible parts. Gelco’s warranty covers manufacturing defects, not service work. As an independent Gelco service provider, we use OEM or equivalent-spec parts and document everything, so warranty claims on defective components remain valid. Call (213) 459-6058 if you need help determining whether a failure is defect- or wear-related.
Yes, for most lines. We stock common Gelco hardware and source specialty items through our Haven buying network. For discontinued series, we specify equivalent-grade stainless or aluminum from DuraFlex or Olympia Chimney with matching thermal and corrosion ratings. We never leave you waiting on an indefinite backorder.
The camera scan decides. We look for liner wall loss exceeding 30 percent, damper frame cracks that compromise the seal, or crown spalling that exposes the chimney’s structural concrete. If any of those conditions appear, we show you the footage and quote both repair and replacement options. Some work can wait a season; some can’t. You’ll know which is which before you decide.
Most Gelco chimney repairs in Pasadena are completed in two to four hours on site, with scheduling one to three business days after inspection. Crown work or liner sections may need a return visit for full cure time. We give you the full timeline in writing before booking.
A failed damper wastes heat and draws cold air. A cracked crown admits water that freezes, expands, and destroys the chimney from the top down. A compromised liner can leak combustion gases, including carbon monoxide, into living spaces. The camera footage tells us which risks are real and which are theoretical for your specific system. Call (213) 459-6058 for a free inspection and an honest assessment of urgency.
