Kevin N. Chimney Corp delivers specialized chimney sweep services across the Greater Seattle Metro, with deep expertise in Mercer Island’s older brick homes. Our licensed team handles inspections, cleanings, repairs, and upgrades tailored to the Pacific Northwest’s climate and local housing stock.
1. Why Mercer Island homes need a chimney sweep with masonry expertise
A chimney inspection is a thorough visual and instrumental assessment of your flue, liner, masonry, and connections to identify hazards, deterioration, or code violations. Mercer Island’s older brick chimneys—many built before modern building codes—often hide hidden damage like cracked liners, eroded mortar joints, or water-damaged crowns. Our team specializes in diagnosing these issues before they become costly emergencies. We use high-resolution cameras and moisture meters to spot problems in Mercer Island’s unique climate, where damp winters and summer heat cycles accelerate masonry wear.

2. The 3 most common Mercer Island chimney problems we fix in older brickwork
In Mercer Island, we consistently see three issues in homes built before the 1980s: cracked clay tile liners (a fire hazard), deteriorated mortar joints (letting water infiltrate), and damaged chimney crowns (allowing rain to pool and freeze). These problems are magnified by Mercer Island’s proximity to Lake Washington, where humidity lingers and freeze-thaw cycles stress masonry. We repair liners with stainless steel sleeves, repoint mortar with Type N or Type S mortar (matched to your brick), and rebuild crowns with a waterproof, durable mix.

3. How Mercer Island’s climate affects your chimney’s lifespan
Mercer Island’s wet winters and hot, dry summers create a perfect storm for chimney deterioration. Water absorption leads to spalling bricks and eroded mortar, while summer heat and UV exposure can crack masonry seals. We recommend sealing older brick with a breathable, silane-based sealer every 3–5 years to prevent moisture intrusion without trapping water inside. Learn seasonal maintenance tips Mercer Island, WA
4. What a Greater Metro Area chimney sweep includes (and what it shouldn’t)
A proper chimney sweep in the Greater Seattle Metro goes beyond brushing flues. We inspect the entire system: flue, liner, smoke chamber, damper, firebox, and exterior masonry. We check for creosote buildup (a leading cause of chimney fires), blockages, and structural issues like leaning chimneys. Avoid sweeps that only clean the flue without assessing the liner or masonry—this is a red flag for older Mercer Island homes. See our full service list ((the Chimney Safety Institute of America (CSIA)|https://www.csia.org/))
5. How often Mercer Island homeowners should schedule sweeps and inspections
For wood-burning fireplaces in Mercer Island, the Chimney Safety Institute of America recommends sweeping when creosote reaches 1/8 inch or more, and inspecting annually. Gas fireplaces need inspections every 1–2 years to check for venting issues or corrosion. If you use your fireplace weekly in winter, consider a mid-season sweep to prevent buildup.

6. Why Mercer Island homeowners trust us for liners, caps, and upgrades
Older Mercer Island chimneys often lack proper liners or have deteriorated ones. We install stainless steel liners to improve draft, reduce creosote buildup, and meet modern safety codes. Chimney caps are another critical upgrade—we recommend mesh caps to block debris, birds, and rain while allowing proper airflow. Our caps are custom-fitted to Mercer Island’s wind patterns to prevent lifting. Explore our liner and cap options Compare repair vs. replace

Frequently Asked Questions
My Mercer Island brick chimney has white stains on the exterior. Is this just efflorescence, or something worse?
White stains are usually efflorescence—mineral deposits from water evaporation—but they signal moisture intrusion. If the stains are accompanied by cracked mortar or spalling bricks, it’s time for a repair. We’ll diagnose the source and recommend repointing or a crown repair to stop further damage.
Why does my Mercer Island chimney smell like mildew even when I don’t use the fireplace?
A musty odor often means water has penetrated the masonry or liner, creating a damp environment for mold and mildew. This is common in Mercer Island’s humid climate. We’ll inspect for leaks, check the liner condition, and recommend sealing or a stainless steel liner to eliminate the problem.
Can I burn driftwood from Lake Washington in my Mercer Island fireplace without harming my chimney?
Driftwood can contain salt and other contaminants that accelerate creosote buildup and corrode liners. The EPA’s Burn Wise program recommends only seasoned, dry hardwoods for burning. If you’ve used driftwood, schedule an inspection to check for excessive creosote or liner damage.
My Mercer Island chimney leans slightly. Is this an emergency, or can it wait until spring?
A slight lean can wait if it’s stable, but any movement warrants an immediate inspection. In Mercer Island, soil shifts near Lake Washington can exacerbate leaning. We’ll assess the foundation, mortar joints, and flue to determine if it’s a masonry issue or a structural problem requiring underpinning.
