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.

Why Trust Emberly Chimney Cleaners Sherman Oaks for Your Gelco Chimney Cleaning?
Corrine Halstead and our crew have been working chimneys across Sherman Oaks for years, including the older wood-framed homes along Ventura Boulevard where the fireboxes get heavy use during cooler months, and we also offer Sherman Oaks Gelco service throughout the area. Corrine learned the trade at Apex Technical School in Manhattan before making her way west, and eighteen years in the trade shows in how we read a Gelco system: findings first, opinion second, price in writing before anyone picks up a tool.
The camera doesn’t lie, and neither does the written quote.
Our Gelco work covers the full product line, from 1970s prefab wood-burning units with 8″ or 10″ triple-wall chimneys to direct-vent gas systems and multi-flue cap assemblies. We source quality aftermarket replacement parts when OEM Gelco components are discontinued or overpriced, and we always tell you when repair stops making sense and replacement is the honest answer. Every technician is background-checked and uniformed, with license information displayed on every page. Calls are answered by a live person, 24 hours a day, 7 days a week.
We’ve completed more than 38,000 chimney inspections and cleanings since 2009. Every one had a written price before work started and a documented record when it was done.
Common Gelco Chimney Cleaning Problems We Fix in Sherman Oaks
- Rusted or pitted triple-wall chimney sections at the roof line. Sherman Oaks’ extreme summer heat - regularly exceeding 100°F - followed by winter rains creates a dry-summer/wet-winter cycle that accelerates corrosion at the outer jacket and flashing collar on Gelco 8″ and 10″ triple-wall systems. We see this most on 1970s-80s builds where the original galvanized outer wall has finally given way. The fix: section replacement or full chimney rebuild, with waterproofing applied to the new collar and crown to slow the next round of corrosion.
- Cracked or spalled firebrick and refractory panels. Decades of Valley heat cycling without proper annual sweeping leaves Gelco factory-built fireboxes with deteriorated refractory panels that no longer reflect heat properly. In Sherman Oaks, this is compounded by earthquake history - many of these chimneys took hits in 1994 and received only cosmetic patching. We inspect with a camera down the flue and assess whether repointing and panel replacement will hold, or if the firebox is past honest repair.
- Deteriorated chase cover and multi-flue cap seals. SCAQMD No Burn Days idle Sherman Oaks fireplaces for 80-100+ days per year, letting moisture sit in the flue instead of drying out with regular use. Gelco multi-flue cap seals fail, rain runs straight down, and you get a creosote-and-water slurry coating the flue walls. We were called out to a 1972 Sherman Oaks ranch house with exactly this problem - musty odor whenever the Santa Ana winds picked up. Our tech pulled the Gelco cap, found the failed seal, swept roughly a full bucket of water-damaged creosote with rotary poly brushes, reset and sealed the cap, and waterproofed the crown and flashing collar.
- Damper and screen assembly failures. Warped damper plates and broken screen rods on Gelco factory-built units no longer seal or operate properly. This is functional failure, not cosmetic - a warped damper leaks conditioned air year-round and won’t control draft when you do burn. We stock quality aftermarket dampers and screen assemblies for Gelco units and install with a written warranty.
- Animal colonization in idle flues. Because Sherman Oaks chimneys sit unused so many days per year, European starling nests and raccoon debris are routine findings here rather than heavy creosote buildup. Our service profile skews toward animal exclusion and cap installation, with stainless steel mesh screens fitted to Gelco multi-flue caps to stop re-entry without blocking draft.
BeforeAfterGelco Parts & Our Repair-vs-Replace Approach
We source quality aftermarket replacement parts for Gelco systems - dampers, caps, screens, firebrick, chase covers - through our Haven buying network, specifically to keep customer prices honest. When OEM Gelco parts are discontinued or priced beyond what the repair justifies, we use compatible components from DuraFlex, HeatShield, and other proven suppliers. We never claim OEM-only status or any Gelco warranty endorsement.
Our repair-vs-replace decision is straightforward: we show you the camera footage, explain what we found, and give you a written price for each option. If a Gelco firebox is past the point where repair makes sense, we’ll say so plainly. No one picks up a tool until you’ve seen the documentation and approved the scope in writing. Clause 1 of the Haven Standard requires it.

Our Gelco Service Process - Step by Step
- 1
Diagnosis with camera-scan inspection. We run a camera down the full length of your Gelco flue, document the liner condition, creosote class, and any structural damage. For prefab units, we inspect the firebox refractory panels, damper operation, and screen assembly. You get the photo record before we discuss next steps.
- 2
Written price and scope before any work. We deliver a written price, written scope, and written warranty before anyone starts - not after the tech is already in your home. Haven Standard Clause 1. No exceptions.
- 3
Repair or install with documented procedure. For cleaning: rotary poly brushes sized to your Gelco flue diameter, HEPA-contained debris removal, and disposal. For repair: OEM-compatible parts installed to manufacturer-clearance specs. For cap and crown work: sealed, waterproofed, and photographed.
- 4
Post-service testing and documentation. We verify draft, damper seal, and cap integrity. You walk away with photos, camera footage, a written scope of work performed, and warranty documentation. Clause 4 of the Haven Standard requires this record on every job.

FAQs - Gelco Chimney Cleaning Service in Sherman Oaks
Yes, for most Gelco prefab units from the 1970s through 1990s, though some original OEM components have been discontinued. We source quality aftermarket replacement parts - dampers, firebrick panels, chase covers, screens - that meet or exceed original specifications, and we’ll tell you before ordering if a particular part is unavailable. Call (424) 414-6048 and we’ll check your model and year.
This is almost always a failed chase cover seal or deteriorated damper letting air wash down the flue, carrying old creosote odor into your living space. In Sherman Oaks, the combination of long idle periods due to No Burn Days and Santa Ana wind pressure makes this especially common, though we see similar patterns with Gelco service in Studio City. A camera inspection confirms the source; sealing the cap and sweeping the flue usually resolves it. Call (424) 414-6048 for an exact quote - estimates are free.
NFPA 211 recommends annual inspection for all chimney systems, but Sherman Oaks burning patterns differ from colder markets. With 80-100+ No Burn Days per year, many Gelco wood-burning systems here accumulate light creosote and more moisture or debris than heavy combustion residue. We often find that animal nesting and chase cover leaks drive service frequency more than creosote buildup. An annual camera inspection tells you whether sweeping is actually needed that year. Call (424) 414-6048 to schedule.
We answer this with camera footage and a written price for each option. If the refractory panels are cracked but the steel wrapper and flue collar are sound, panel replacement and repointing may give you years of service. If the wrapper is rusted through, the flue collar is separating, or earthquake damage has compromised the structure, replacement is the honest answer. We show you what we found and let you decide. Call (424) 414-6048 for a free second opinion.
We service Gelco direct-vent gas fireplaces and their venting components, including burner assembly cleaning, pilot troubleshooting, and vent cap inspection. Gas systems don’t produce creosote, but they do require clear venting and proper draft pressure. We inspect with the same camera documentation standard applied to every job. Call (424) 414-6048 to book.
