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 Bellevue: What to Know First
We provide independent Gelco chimney repair in Bellevue, typically completing most jobs within one to three business days after inspection. A written price and scope arrive before any work starts, and every repair includes a camera-scan verification and documented photo record under Haven Standard Clause 4. If you own a Gelco chimney cap, Gelco flashing kit, or Gelco pre-fabricated chimney component and you’re seeing water intrusion, rust streaking, or mortar separation, this page is for you. Call (425) 696-0387 to schedule an inspection or bring us a competitor’s written estimate for a free second opinion.
How Gelco Products Fail - and How We Fix Them
- Gelco Model C chimney caps: The 304 stainless mesh on older Model C caps develops pinhole corrosion at the weld points where Bellevue’s salt-laden winter air settles. We see this most often on Lakemont and Somerset homes with south-facing exposures. Our fix: remove the cap, document the flue condition with camera, and install a replacement with heli-arc welds and a reinforced skirt - or switch to a comparable Olympia Chimney cap if the flue sizing allows.
- Gelco pre-fab chimney flashing kits: The standard Gelco base flashing uses a two-piece overlap that relies on caulk at the vertical seam. After seven to ten years of Puget Sound freeze-thaw, that caulk line cracks and the seam lifts. Water runs behind the siding, not through it, so the damage hides until the sheathing softens. We strip to the deck, install a custom-formed single-piece base with a reglet into the masonry, and counterflash with copper. No caulk dependency.
- Gelco chimney liner collars: The collar clamp on Gelco’s flex liner termination kits loosens as the liner breathes through heating cycles. The gap is usually 1/8 inch, enough to spill condensation down the exterior flue face in Bellevue’s high-humidity months. We torque-test the collar, replace the factory worm-gear clamp with a constant-tension T-bolt, and seal with HeatShield Cerfractory foam where the manufacturer spec allows.
- Gelco brick-sealer applications on historic chimneys: Some Bellevue owners applied Gelco’s silane-siloxane sealer to pre-1960 brick that was already spalling. The sealer trapped moisture behind the crust, accelerating freeze-thaw damage. We don’t seal until we determine why the brick is breathing water - usually failed crown wash or open mortar joints above. The repair is repointing with Type N mortar, crown rebuild, then a breathable treatment if the masonry tests dry.
- Gelco chimney crown forms: Gelco’s pourable crown forms are sized for standard flue configurations. On Bellevue’s many custom-built homes with offset flues or multiple appliance terminals, the form doesn’t seat square. The resulting crown has a thin spot at the high corner that cracks in the first winter. We form crowns by hand with a slope gauge and steel reinforcement, or pour to a custom-built frame when the flue arrangement is non-standard.
Our Gelco Chimney Repair Process
- 1
Call and schedule. A live person answers. We ask for the Gelco model or series if you know it, the symptom you’re seeing, and whether you have any prior inspection reports. We assign a technician and text you when they’re en route.
- 2
NFPA 211 Level 2 inspection. Camera down the flue, photos of the exterior, moisture readings on accessible framing. We look for the failure pattern that matches your Gelco component, not just generic damage.
- 3
Written price and scope. Before any tool comes out, you get a fixed price, the parts specification (OEM Gelco or cross-referenced equivalent from our Haven buying network), and the warranty terms. Haven Standard Clause 1: have it in writing.
- 4
Repair with documentation. We photograph each stage - old part removed, substrate prepared, new part installed, torque settings where applicable. Corrine Halstead reviews any deviation from the written scope before the tech proceeds.
- 5
Camera verification and test. For liner work, a smoke pellet and draft gauge. For flashing, a water test from the hose. For crowns, a level and slope check. The camera goes back down to confirm nothing shifted during the repair.
- 6
Photo record and warranty. You receive the complete file: inspection photos, repair photos, readings, and the 365-Day Done Right Promise stamped on the invoice. The archive uploads to your customer portal under Haven Standard Clause 4.

Why Bellevue Homeowners Call Level Two Chimney Bellevue for Gelco Work
We’ve inspected and repaired Gelco components in Bellevue since 2015, including the older wood-burning fireplaces in Lakemont where the homes see real use through the wet season. Corrine Halstead pulls the camera footage and walks customers through exactly what it shows - no summaries, no guesswork. The camera doesn’t guess. Neither do I.
Our materials come through the Haven buying network: Gelco when the spec calls for it, DuraFlex for liner jobs, HeatShield for resurfacing, Olympia Chimney and Famco for cross-referenced alternatives that keep pricing honest. Every technician is background-checked, uniformed, and named on your appointment. The 365-Day Done Right Promise means if the repair fails, we return and make it right - no re-inspection fee, no argument. And Clause 4 of the Haven Standard requires that photo record on every job, running continuously since 2009. You don’t have to trust our word. You trust what you can see.
FAQs
No, if the repair uses OEM-equivalent parts and follows the original installation spec. As an independent Gelco service provider, we source through Haven’s buying network and document part numbers on every invoice. If your Gelco component is still under original warranty, we’ll flag that before quoting and advise whether a manufacturer claim is the better path. Call (425) 696-0387 and we’ll check the install date against Gelco’s coverage terms.
Yes, for most lines through 2015 and later. For discontinued pre-2010 caps and collars, we cross-reference to Olympia Chimney or fabricate from copper or stainless stock in our supplier network. We never quote a repair we can’t complete with documented parts. Bring us your model number and we’ll confirm availability before scheduling.
The camera decides, not the calendar. We look for three things: structural integrity of the wythe (the inner wall), liner condition, and water path. If the wythe is sound and the liner is intact, repair is usually viable. If the wythe has shifted or the liner is perforated below the roofline, we quote both options with a written price for each. You get the photos and the recommendation, not pressure. Call (425) 696-0387 for a free inspection.
Water continues its path. Spalling brick loses mass, mortar joints hollow, and the liner gap widens. In Bellevue’s climate, that timeline is faster than drier regions because the masonry rarely dries fully between October and April. The risk is a chimney fire from creosote ignition in a compromised flue, or carbon monoxide spillage through a cracked liner into living space. Both are real, both are preventable, and neither requires urgency theatre - just a scheduled inspection and a written repair plan.
Most inspections happen within two business days. Repairs requiring no custom fabrication typically schedule within three to five days after you approve the written price. Crown rebuilds or partial rebuilds needing permit review may take ten to fourteen days. We don’t promise same-day dispatch because the inspection comes first, and the inspection determines what we actually need to fix. Call (425) 696-0387 to book your slot.
