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 Liner & Rebuild in Sherman Oaks: What to Know First
We provide independent Gelco chimney liner and rebuild service in Sherman Oaks, with most Gelco liner replacements and partial rebuilds completed in one to two days once parts are confirmed. A written price and scope are delivered before any work starts, and every job includes a camera-scan inspection with documented photo record. If you own a Gelco stainless steel or flexible liner system and need replacement, repair, or a full chimney rebuild, call us at (424) 414-6048 for a free estimate. Corrine Halstead and our crew have worked Gelco systems across Sherman Oaks for years, including the older wood-framed homes along Ventura Boulevard where fireboxes see heavy winter use.
How Gelco Products Fail - and How We Fix Them
- Gelco UltraPro stainless liners develop crevice corrosion at the flex-to-rigid transition joints, especially in Sherman Oaks homes where temperature swings from Santa Ana wind events stress the metal. We cut back to sound metal, source matching gauge 316Ti alloy through our Haven buying network, and weld the new joint rather than relying on standard clamps alone.
- Gelco FlexKing multi-ply liners collapse at the offsets in pre-1970s chimneys common south of Ventura Boulevard, where the original clay flue was built with sharp parging offsets. We don’t just reline; we smooth-parge the offset with HeatShield Cerfractory Foam first, then pull the correct diameter FlexKing replacement so it doesn’t hang up on the next heating season.
- Gelco top-sealing dampers integrated with liner tops seize when the stainless cable sheaths fill with crystallized creosote, a Class III buildup we see regularly in homes burning oak and almond from local suppliers. We replace the cable assembly with a Famco equivalent rated for the same cycle count, or convert to a Lyemance-style pivot if the owner prefers.
- Gelco liner collars and top plates warp from thermal cycling in chimneys with exterior exposure on north-facing walls, which stay colder longer and heat unevenly. We measure the ovality with a digital caliper, source the correct Gelco or Olympia Chimney replacement spec, and bed it in high-temp silicone rather than dry-mounting.
- Gelco systems in homes with earthquake-shifted chimney stacks, particularly in the hillside zones near Mulholland Drive, separate at the thimble connection to the appliance. We camera-locate the separation, determine if the shift is active or settled, and either re-secure with a listed support system or recommend partial rebuild if the masonry continues to move.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24/7. We book a Level 2 inspection with camera scan. Clause 4 of the Haven Standard requires the photo record on every job.

Inspection and documentation. Our tech runs the camera down the flue, notes liner gauge, joint condition, creosote class, and masonry integrity. You get the footage and a written findings report.
- 3
Parts decision. We identify your Gelco series, check OEM availability against our Haven network stock, and quote both options when an aftermarket equivalent meets or exceeds spec. No parts move without your written approval.
- 4
Repair or rebuild. We execute the scoped work: liner pull, weld, or full rebuild. Background-checked, uniformed crew. License number on the work order. You get a text when we’re en route.
- 5
Post-work testing and record. Smoke test, draft reading, final camera pass. Written warranty and completed photo record delivered. The 365-Day Done Right Promise begins.

FAQs
No. Gelco’s limited warranty covers manufacturing defects in the liner material itself, not who installs it. As an independent Gelco service provider, we document installation per manufacturer guidelines so any legitimate material claim remains valid. If you’re unsure about your warranty status, bring us your paperwork and we’ll read it with you - no charge for that. Call (424) 414-6048.
Most Gelco liner replacements are completed in one day once parts are on-site. Two days if we’re smoothing offsets with HeatShield or doing a partial rebuild. We don’t book the job until parts are confirmed, so we don’t start and disappear. Call (424) 414-6048 to check current Gelco availability.
Localized damage - a single joint failure, a small corrosion spot, a detached collar - can sometimes be repaired with a listed patch or section replacement. We camera-locate the damage, show you the footage, and quote both repair and replacement so you decide. If the liner is more than 15 years old and showing multiple failure points, replacement is usually the better value. Call (424) 414-6048 for a free inspection.
We source through our Haven buying network across multiple suppliers, including DuraFlex and Olympia Chimney, and we’ll quote an equivalent that meets or exceeds your Gelco spec if OEM stock is delayed. We don’t start work with uncertain parts. You’ll know the exact part number, manufacturer, and delivery date before you sign the scope. Call (424) 414-6048 for current availability.
NFPA 211 recommends annual inspection for all chimney systems, and we agree, especially in Sherman Oaks where Santa Ana wind events and occasional seismic movement stress liners and masonry. Gelco stainless liners can develop hidden corrosion at joints that a camera catches early. Our Level 2 inspection includes the camera scan and photo record as standard under Haven Standard Clause 4. Call (424) 414-6048 to schedule.
