Fast, Reliable Chimney Liner & Rebuild Across Mercer Island
A failing chimney liner in Mercer Island is not a repair you can schedule around. When creosote has corroded the flue tiles, or lake-effect moisture has spalled the mortar joints beyond what a simple repointing can fix, smoke and carbon monoxide find paths into wall cavities and living spaces. We have rebuilt chimney flues and installed stainless steel liners on homes from the western bluffs overlooking Lake Washington to the wooded interior near Island Crest Way, and we carry the materials to complete most Mercer Island Fireplace Services jobs in a single visit. Call (844) 803-1545 and a live person will answer, 24 hours a day.
Why Hearthstone Chimney Co. Is Mercer Island’s Preferred Chimney Liner & Rebuild Company
We have been working on Mercer Island chimneys since the early 1990s, back when many of the island’s mid-century ranches were hitting their first major liner failures. Over 42 years in business means we have seen how the 98040 microclimate treats masonry differently than mainland King County, and we document every inspection with photos you can see and a plain-English verdict.
Our technicians are background-checked, uniformed, and trained to recognize the specific failure patterns that develop in homes surrounded by Douglas fir and western red cedar. Mercer Island residents do not want a hard sell; they want someone who will say plainly whether the liner can be repaired with HeatShield refractory mortar or whether the flue is past saving and needs a full stainless steel replacement. We give no-hassle upfront pricing, the number on the estimate is the number on the invoice, and every job is backed by our 90-Day Done Right Promise in writing.
Calls are answered by a live person, not a voicemail system or callback queue. If you are on Mercer Island and smell smoke in an upstairs bedroom or see mortar debris in your firebox, we will be there when we say.
Our Chimney Liner & Rebuild Services in Mercer Island
Stainless Steel Liner Installation
For most Mercer Island homes with original clay flue tiles in a 1950s-1970s masonry fireplace, a stainless steel liner is the permanent fix. We size the liner to your appliance using DuraFlex or Olympia Chimney components, and we pull the liner down from the roof in a single visit when possible. The lake-effect humidity here accelerates corrosion in lower-grade metals, so we do not use builder-grade substitutes. A stainless steel liner installed correctly will outlast the second mortgage.
Flexible Liner Systems
Some of the custom homes built during Mercer Island’s 1980s-2000s expansion have offset flues or tight clearances that rigid pipe cannot navigate. We use flexible DuraFlex liners for these applications, sized and insulated to meet Washington State venting codes. The flexible liner also accommodates the slight settling that is common in homes built on the island’s sloped lots above I-90. Every flexible liner job includes a Level-2 camera inspection before and after, with photos you keep.
Liner Replacement for Zero-Clearance and Gas Fireplaces
Many Mercer Island homes with high-end gas conversions or zero-clearance inserts from the 1990s and 2000s have factory-built metal chimneys with corroded or improperly sized liners. We replace these with listed, code-compliant components from Famco and Copperfield. Because these systems vent differently than traditional masonry, we check for proper draft performance given Mercer Island’s cold-air inversions in winter, not just whether the pipe fits.
Partial Chimney Rebuild
When the upper courses of a chimney have spalled from decades of lake-effect freeze-thaw cycling, but the firebox and lower structure are sound, we perform a partial rebuild. This is common on mid-century ranches in the Island Crest Way corridor and the older neighborhoods near Luther Burbank Park. We match existing brick and mortar where possible, and we always install a proper crown with drip edge to shed the heavy rainfall that 98040 receives. Our Chimney Liner & Rebuild team documents the structural condition with photos before lifting a trowel.

Trusted Brands We Service in Mercer Island
We stock professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. For Mercer Island customers, this means we are not ordering parts from a warehouse across the state and making you wait two weeks. We carry the liner diameters, insulation blankets, and refractory mortors that match the island’s common chimney configurations, from the older masonry flues to the factory-built systems in newer construction, including our Chimney Cap & Crown in Mercer Island solutions. When we say most jobs are completed in a single visit, it is because the right materials are already on the truck.
Common Chimney Liner & Rebuild Problems We See in Mercer Island Homes
- Spalled flue tiles from freeze-thaw cycling. The elevated humidity around Lake Washington means more moisture absorption into masonry, and winter temperature swings cause the surface to pop. We find this in homes throughout 98040, particularly those with original construction from the 1960s and 1970s.
- Heavy creosote glazing in unlined or damaged flues. Mercer Island’s persistently moist air keeps firewood from seasoning properly, and residents burning damp cordwood produce sticky Stage 2 and Stage 3 deposits that accelerate liner deterioration. This is worse here than in drier Eastside neighborhoods.
- Debris-compacted flues from overhanging Douglas fir. Homes on the western shoreline bluffs and in the forested interior routinely have branches within feet of the chimney top. We pull out fir cones, needle mats, and nesting material that technicians in open-lot Bellevue suburbs rarely encounter.
- Corroded factory-built chimney liners in 1980s-2000s custom homes. Many high-end Mercer Island builds used zero-clearance systems with metal liners that have reached end of life. The salt-laden air from Lake Washington accelerates corrosion at the termination cap, a pattern we document during every Level-2 inspection.

Not because of the zip code. Labor rates are consistent across our King County service area. What can add cost on Mercer Island specifically is accessibility, hillside lots with steep roofs require additional safety rigging, and the heavier debris loads from overhanging conifers sometimes mean extra pre-cleaning before liner work can begin. We disclose any such factors in the upfront estimate.

The promise is governed by our K.E.Y.S. values code: Krafted right, Every time, Your home first, Standing behind it.
