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 Tacoma: What to Know First
We provide independent Gelco chimney liner and rebuild service in Tacoma, typically completing liner replacements in one to two days and full rebuilds within a week once parts are confirmed. Every job starts with a written price, a written scope, and a written warranty before any work begins - no exceptions. This page is for homeowners who already know they have a Gelco liner or are seeing the symptoms Gelco units tend to show in the Pacific Northwest climate. If you’re in the North End, Proctor District, or anywhere between the tideflats and Joint Base Lewis-McChord, we can get a technician out with a camera and a written estimate. Call (253) 447-5982 to book.
How Gelco Products Fail - and How We Fix Them
- Gelco Stainless Pro liners develop seam separation at the flex joints after 10-15 years in Tacoma’s wet winters, especially where the chimney crown has hairline cracks letting moisture sit against the collar. The joint loosens, draft drops, and you smell smoke at startup. We cut back to sound metal, sleeve with a DuraFlex or new Gelco section depending on availability, and re-seal with high-temp silicone rated for the flue gas temperature your appliance produces.
- Gelco Pre-Fab chimney systems in homes built 2005-2015 show chase pan rot faster than other brands because the galvanized steel pans were spec’d thinner in that era. Water pools at the corners, rusts through, and stains the siding before you notice interior damage. We fabricate a replacement chase pan in copper or stainless, inspect the surrounding Gelco panels for water tracking, and document everything with photos under Haven Standard Clause 4.
- Gelco flexible liners in oil-burning setups cake with sulfuric sludge that rigid stainless doesn’t allow to shed. The sludge accelerates pitting at the low points, particularly where the liner dips before entering the thimble. We pull the liner, measure wall thickness with a pit gauge, and replace with a properly sized Gelco or HeatShield alternative - or switch to rigid if the flue geometry allows.
- Gelco’s older 316Ti alloy liners in beach-adjacent homes - Browns Point, Dash Point, parts of Ruston - show chloride stress corrosion earlier than inland installs. The salt air penetrates minor crown defects and attacks the titanium-stabilized grain boundaries. We spot this with borescope magnification and recommend a 904L upgrade or full rebuild depending on how far the attack has propagated.
- Gelco connector pipes between fireplace and main flue sag or corrode at the male-female slip joint, creating a gap that spills combustion gases into the smoke chamber. This is invisible from below and often missed on basic inspections. We run the camera through the entire assembly, measure the gap, and replace with OEM Gelco or a machined adapter if Gelco’s run has been discontinued for that series.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, checks Gelco parts availability for your series, and books a Level 2 inspection with camera. You get a text when your tech is en route.
- 2
Camera-scan inspection. We run the borescope from firebox to cap, recording the full flue condition, liner wall thickness, joint integrity, and any spalling or sludge buildup. The camera doesn’t guess. Neither do we.
- 3
Written price and scope. Before any work starts, you receive a written estimate with line-item pricing, the exact Gelco or cross-compatible parts we intend to use, and the warranty terms. Haven Standard Clause 1: have it in writing.
- 4
Parts procurement and repair. We source Gelco, DuraFlex, HeatShield, or Olympia Chimney materials through Haven’s buying network - whichever matches your system’s spec and your budget. Liner replacements typically complete in one day; rebuilds may take two to three depending on masonry cure times.
- 5
Post-repair testing and documentation. We run a smoke test or draft test, verify clearances to combustibles, and deliver your photo record and completed warranty card. Haven Standard Clause 4 requires this documentation on every job.
- 6
365-Day Done Right Promise follow-up. If anything isn’t performing as specified, we return and make it right. The promise is stamped on every job we do.

These are real ranges for Tacoma-area jobs we’ve priced in the last 18 months. Every home differs, and we don’t guess from the driveway. Call (253) 447-5982 for a free estimate - the inspection and written price cost you nothing.
Why Tacoma Homeowners Call Level Two Chimney Tacoma for Gelco Work
We’ve inspected over 38,000 chimneys since 2009, and Gelco products show up regularly in the 1980s-2010s builds across Tacoma’s hillside neighborhoods and shoreline zones. Corrine Halstead and our crew know the difference between a Gelco Stainless Pro and a Gelco Pre-Fab chase system without pulling the cap, because we’ve replaced enough of both to recognize the failure patterns.
Our background-checked, uniformed technicians carry license information on every page of every estimate. You get a named tech, a text when they’re on the way, and a documented photo record when the job is done. If you have a competitor’s written quote on Gelco work, we’ll give you a free second opinion - no obligation, no pressure. And if Gelco parts are back-ordered for your series, we have cross-compatible options from DuraFlex and HeatShield that meet or exceed the original spec, sourced through Haven’s buying network to keep pricing honest.
FAQs
No - Gelco’s limited warranty covers manufacturing defects, not who installs or services the product, provided the work meets NFPA 211 standards and uses compatible materials. As an independent Gelco service provider, we document every step to warranty standards and flag any manufacturing defect we find so you can file directly with Gelco if needed. Call (253) 447-5982 and we’ll review your warranty status during the inspection.
Most Gelco liner replacements are completed in one working day once parts are on hand. If your flue has multiple offsets or requires insulation wrap for zero-clearance compliance, plan for two days. Full rebuilds with masonry cure time typically run three to five days. We never promise speed over proper cure and test cycles.
Localized damage - a separated joint, a pinhole at a low point, minor pitting - can often be section-repaired with an approved sleeve or patch. We make that call based on wall thickness measurements from the camera inspection and a pit gauge reading, not a visual guess. If the liner has lost more than 20% wall thickness in any 12-inch section, we recommend full replacement and explain why in your written estimate.
Some Gelco series from the 1990s and early 2000s are discontinued, but we maintain cross-reference data for compatible DuraFlex, Olympia Chimney, and HeatShield components that meet the original UL listing. If your series is obsolete, we’ll show you the equivalent part, the test data, and the price difference before ordering anything.
A compromised flue liner allows combustion gases, including carbon monoxide, to leak into wall cavities or living space. In wood-burning systems, creosote can reach combustible framing if the liner gap is large enough. The risk escalates with use, not time alone - a cracked Gelco liner in an unused decorative fireplace is a future problem; in a actively used heating appliance, it’s an active hazard. Call (253) 447-5982 for a free camera inspection and we’ll show you exactly what your system looks like right now.
