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.
Gelco Chimney Cleaning in Bellevue, WA | Level Two Chimney Bellevue
We provide independent Gelco chimney cleaning and repair across Bellevue, not as an authorized dealer, but as a crew that has worked on Gelco stainless liners, multi-flue caps, and cast-in-place crowns since the 1990s. The one thing that makes our Gelco work here different: we know how Bellevue’s 37 inches of annual rain, concentrated October through April, attacks Gelco components differently than drier climates, and we stock the specific parts to fix it without ordering delays. Call (425) 696-0387 for a free written estimate.
Why Bellevue Residents Choose Us for Gelco Service
Corrine Halstead, our owner, learned the trade at Apex Technical School in Manhattan before bringing her work west to the Pacific Northwest. She and our crew have been servicing Bellevue properties for several years now, including older wood-burning fireplaces in the Lakemont neighborhood where homes see real use through the wet season. Corrine is known for pulling the camera footage and walking customers through exactly what it shows. No summaries, no guesswork.
We are not a Gelco-authorized service center. We are an independent, Haven Standard shop that specializes in Gelco systems because we have encountered thousands of them in Bellevue homes, particularly in eastern neighborhoods like Lake Hills and Crossroads where 1960s tract houses contain original brick chimneys now 50 to 60 years old. We source genuine Gelco replacement parts through our Haven buying network, and when a part is discontinued, we fabricate custom stainless equivalents to the same tolerances. Every job starts with a written price, a written scope, and a written warranty before any work begins. Clause 4 of the Haven Standard requires a documented photo record on every visit, and we have done this since 2009.
Common Gelco Chimney Cleaning Problems We Solve in Bellevue

- Pinhole corrosion in 1990s Gelco stainless liner kits. The 6″ and 8″ diameter liners installed during that era’s retrofit boom often develop seam corrosion after 25-plus years of Bellevue’s rain cycle, especially when the chimney lacks a proper cap. We camera-scan the full liner length, measure the pitting, and quote replacement only when repair is no longer viable.
- Sagging mesh on Gelco multi-flue caps. Standard stainless mesh corrodes under the weight of wet debris from Bellevue’s dense tree canopy, then sags and traps water on the crown. This accelerates mortar erosion that homeowners mistake for a draft problem. We replace with Gelco-spec or custom-fabricated caps sized to your flue configuration.
- Flat Gelco cast-in-place crowns pooling water. In Lake Hills and Crossroads, original 1960s crowns were poured with no slope. Water sits, wicks into mortar joints, and causes interior spalling that restricts the flue. The camera doesn’t guess. Neither do I. We chip out the old crown and pour a new sloped Gelco-spec crown that sheds rain.
- Seized Gelco top-mount dampers. After sitting through Bellevue’s damp winters, these dampers frequently freeze in the open position, letting rain enter the flue and mix with creosote into a corrosive slurry. We clean the mechanism, assess pitting, and replace with Gelco-compatible dampers when the original is beyond salvage.
- Gas insert retrofits in masonry flues. Many 1980s to 2000s hilltop homes had gas inserts retrofitted into original wood-burning openings during tech-boom renovations. The masonry flue still requires annual inspection and cleaning even though the homeowner considers the fireplace “converted.” We check for deteriorated Gelco liners that vented wood smoke for decades before the gas insert arrived.

AfterGelco Service in Bellevue: What Local Conditions Mean for Your Equipment
Bellevue’s median home sale prices routinely exceed $1.5 to $2 million, making Level 2 chimney inspections during real estate transactions one of the single largest drivers of chimney-service calls in this market. A cracked firebox or deteriorated Gelco liner can derail a seven-figure deal and trigger rushed pre-listing cleanings and inspections. At the same time, the large stock of 1960s to 1970s tract homes in eastern neighborhoods like Lake Hills and Crossroads contain original brick fireplaces now 50 to 60 years old that have absorbed decades of Pacific Northwest rainfall with minimal upkeep, creating a backlog of moisture-compromised masonry that sees renewed attention only when those homes hit the market.
For Gelco owners specifically, this means two very different service profiles across Bellevue. In Lake Hills and Crossroads, the original 1960s Gelco cast-in-place crowns were often poured flat, no slope, so water sits on top and wicks into the mortar joints. When we pull a camera down those flues, we routinely find interior spalling that the homeowner misread as a draft problem, a pattern that simply doesn’t occur in the newer hilltop homes with properly sloped crowns. A homeowner on 156th Ave SE in Lake Hills called us because their wood-burning fireplace smoked into the living room every time they lit a fire. We ran a camera and found the Gelco cast-in-place crown had no slope, allowing decades of rain to degrade the interior mortar and drop debris onto the damper shelf, restricting the flue. We chipped out the old crown, poured a new sloped Gelco-spec crown, replaced the damaged damper, and swept the flue. The draft restored immediately.
Gelco Models & Products We Service in Bellevue

We work on the full Gelco product line installed in Bellevue homes: Gelco Stainless Steel Liner Kits in 6″ and 8″ diameters; Gelco Multi-Flue Caps in stainless and copper; Gelco Cast-in-Place Masonry Crowns; and Gelco Top-Mount Dampers. Our Gelco sales & service inventory includes genuine Gelco replacement components sourced through our Haven buying network, plus custom-fabricated stainless equivalents for discontinued models. Many older liner kits are no longer manufactured, so we keep 304 and 316 stainless sheet stock on hand to fabricate matching sections without the two-week order delay. This matters in Bellevue’s October-to-April burning season, when a failed liner or seized damper means no heat until the part arrives.

FAQs - Gelco Chimney Cleaning in Bellevue
Yes, it may. Infrequent burning does not stop Bellevue’s 37 inches of annual rain from corroding the seam welds on 1990s Gelco stainless liners. We have replaced liners in homes where the fireplace saw use twice yearly, because the pinhole corrosion was advanced enough to pose a carbon monoxide risk. The only way to know is a camera inspection. Call (425) 696-0387 for an exact quote. Estimates are free.
Moisture. Bellevue’s damp winters cause the damper mechanism to corrode and seize, often in the open position where it cannot be closed by hand. Rain then enters the flue and mixes with residual creosote into an acidic slurry that accelerates liner damage. We disassemble, clean, and lubricate the mechanism; if the pivot or frame is pitted, we replace with a Gelco-compatible damper. Call (425) 696-0387 for an exact quote. Estimates are free.
We can improve on it. Original Gelco cast-in-place crowns in Lake Hills and Crossroads were frequently poured flat, which is why they failed. We chip out the old crown and pour a new Gelco-spec sloped crown that sheds water per current standards, using materials from our Haven network suppliers. The result matches the original dimensions but performs better. Call (425) 696-0387 for an exact quote. Estimates are free.
Get a second opinion with documentation. We provide Level 2 camera inspections with photo records that satisfy buyer, seller, and insurer under Haven Standard Clause 4. If the cap is failed, we quote replacement in writing with a completion timeline that fits your closing schedule. We have handled pre-listing sweeps and inspections on Bellevue homes from $800,000 to $3 million. Call (425) 696-0387 for an exact quote. Estimates are free.
Yes. Many Bellevue hilltop homes had gas inserts installed during 1990s and 2000s renovations, but the original masonry flue and any remaining Gelco liner still require annual inspection and cleaning. The insert does not eliminate creosote buildup in the connector, and deteriorated liners can leak combustion gases into wall cavities. We inspect the full system, not just the insert. Call (425) 696-0387 for an exact quote. Estimates are free.
