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.

AfterFast, Reliable Chimney Inspection Across Mercer Island
A chimney inspection in Mercer Island typically runs $189 – $549 depending on the level, and most Level 1 and Level 2 inspections are completed in one visit. If you live on Mercer Island, you already know the island’s lake-locked humidity treats masonry differently than the mainland does. Mortar stays wetter longer, crowns crack sooner, and flashing fails faster here than in Bellevue or Seattle. We dispatch our Chimney Inspection team to Mercer Island from our Seattle office, and you’ll know exactly who’s showing up before the truck leaves the mainland. Call (336) 863-3889 to schedule.
Why Alcott Chimney Sweep Is Mercer Island’s Preferred Chimney Inspection Company
Ruben Castellano built Alcott Chimney Sweep in 2002 on a simple rule: the customer should see what we see before they spend a dollar on repairs. On Mercer Island, where high property values attract aggressive upselling from out-of-town chimney companies, that rule matters more than anywhere else we work. We don’t recommend a new liner, a crown rebuild, or a waterproofing treatment without putting the camera footage in front of you first. If we can’t show you the defect, you shouldn’t pay to fix it.
Every technician we send to Mercer Island is background-checked and identity-verified through the Threshold Standard, which is the vetting protocol our parent company, Threshold Group, applies to every hire. You’ll receive the technician’s name and photo before arrival, and they’ll show a photo ID badge at your door. No exceptions. Mercer Island homeowners, many of whom are home alone or have young kids, tell us this is the main reason they keep calling us back.
We answer the phone with a live person around the clock. If you smell smoke at 11 p.m. on a November night and need to know whether it’s an emergency or just a damp flue, you’ll talk to a human, not a voicemail queue.
Fireplace Inspection in Mercer Island
Fireplace Inspection on Mercer Island means something specific here because of what the island’s housing stock actually looks like. Most single-family homes were built between the 1950s and 1970s, and their original masonry fireplaces are now 50 to 70 years old. When we inspect a Mercer Island fireplace, we’re checking the firebox, damper, smoke shelf, and the flue above it for exactly the damage this island’s lake-humidity climate produces. A standard fireplace inspection in Mercer Island runs $189 – $289.
What We Check
We examine the firebox for cracked refractory panels and separated mortar joints, and we open and close the damper by hand to confirm it seats correctly. On Mercer Island specifically, rusted damper assemblies are common because lake-effect humidity keeps the firebox damp even through summer.
When to Book One
Book an inspection before your first fire each fall, after any major weather event, or anytime you notice staining on the firebox floor. If your fireplace is original to the home and has never been inspected, the case for doing one now is stronger. Most Mercer Island fireplaces that fail inspection fail because of moisture problems, not overuse.
Chimney Inspection Services in Mercer Island
Chimney Inspection Services in Mercer Island come in three levels, and the one you need depends on what’s changed since your last inspection. Level 1 is a visual check of the accessible portions of the chimney, appropriate when nothing about the system has changed. Level 2 adds a camera scan of the flue interior and runs $299 – $449 on Mercer Island. Level 3 involves opening walls or chimney structure to access hidden areas and starts around $549. Most Mercer Island homes need at least one Level 2 inspection, and here’s why: so many of you still have original clay-tile liners that have never been relined.
Camera Inspections
A camera inspection is the only way to see what a clay-tile flue liner actually looks like after 50 years of use. We run a high-resolution camera up the flue and record the entire pass. You watch the footage with us on a tablet, in real time, so you can see every crack, gap, and creosote buildup yourself.
Real Estate Inspections
Mercer Island real estate transactions almost always require a Level 2 chimney inspection now, especially on lakefront properties where moisture intrusion history shows up on buyer’s disclosure forms. We provide the written report and annotated photos sellers and buyers both want before closing. Real estate inspection pricing starts at $299.

Trusted Brands We Service in Mercer Island
We work with professional trade materials only, because Mercer Island chimneys deserve repairs that last longer than the inspection cycle. We install and service DuraFlex liner systems, HeatShield resurfacing, and Olympia Chimney products, and we keep common Mercer Island repair components in local stock so we’re not waiting on a shipment from the mainland when your crown needs sealing before the next rain. When a gas insert or pellet stove is venting into an original clay-tile flue, we often specify HeatShield or a DuraFlex reline to bring the system back to code.
Common Chimney Inspection Problems We See in Mercer Island Homes
- Saturated mortar and receding joints on lake-facing stacks. The western and eastern slopes of Mercer Island get consistent lake-effect humidity, and masonry chimneys there hold moisture in the mortar between burning seasons. We regularly see efflorescence and crown cracking on homes that have never had a chimney leak show up on the ceiling.
- Original clay-tile flue liners now venting high-efficiency gas inserts. Many island homeowners replaced wood-burning fireplaces with gas inserts in the 2010s but never relined the original flue. The insert’s lower flue-gas temperatures accelerate condensation and creosote deposition inside old clay tiles, creating a hazard the insert manual itself warns against.
- Flashing failures that present as firebox stains, not ceiling stains. On split-level and ranch homes especially, water migrating through failed flashing travels down the chimney stack and pools at the firebox floor. Nobody sees a ceiling stain, so nobody thinks there’s a leak. By the time spalling starts, the crown and flashing have both failed.
- Wind-driven downdraft on lakefront properties. Homes near the water on Mercer Island get steady wind off Lake Washington that pushes smoke back down the flue and into living rooms. This isn’t a cleaning issue and it’s not an old-fireplace issue. It’s a chimney-cap issue, and standard caps don’t fix it. We specify wind-directional caps for these homes.

FAQs About Chimney Inspection in Mercer Island
Once a year, even if you only light a fire on holidays. Mercer Island’s lake-humidity climate attacks masonry chimneys continuously, not just during burning season. The moisture cycle never stops, and the damage it causes (receding mortar joints, crown cracking, damper rust) happens whether or not you burn. Burning a few fires a year also produces creosote that sits in the flue for months, hardening into a glaze that’s harder to remove later. Call (336) 863-3889 and we’ll get you on the schedule before the rainy season hits.
Yes, and this is the single most important inspection we do on Mercer Island. A 1960s clay-tile liner has been absorbing island humidity for six decades, and the joints between the tiles are the first thing to fail. The only way to see the condition of that liner is with a camera. Without it, you’re guessing. We’ll show you the footage live, and if the liner is sound, we’ll say so plainly and recommend nothing further.
No. On Mercer Island, consistent wind off Lake Washington pushes down the flue and forces smoke back into the house, and this happens on new fireplaces as often as old ones. The usual fix is a wind-directional chimney cap, not a cleaning or a rebuild. If a technician tells you this is just “an old fireplace problem,” get a second opinion. Call (336) 863-3889 and we’ll diagnose it on site.
Yes, and it’s more serious here than it would be in Bellevue or Seattle. The white staining is efflorescence, which means water is moving through the crown and carrying soluble salts out of the masonry. On Mercer Island, that crown stays wet longer because of the lake-humidity microclimate, so the crack opens wider every season. Once water starts getting into the flue, the damage compounds quickly. We’ll show you the crack on camera and give a written quote for crown sealing or rebuild.
Yes, and if the insert was vented into an original clay-tile flue without a reline, the need is urgent. Your insert’s manual almost certainly states that the flue must be properly sized and lined for gas. When it isn’t, condensation from the cooler exhaust eats at the old tile, accelerates creosote buildup, and can push carbon monoxide back into the house. We’ll camera-scan the flue to confirm what’s actually inside. If it needs a reline, we’ll show you the footage before recommending anything. Call (336) 863-3889 for an inspection.
