Chimney Liner Replacement Seattle, WA

Chimney liner replacement is the job you need when the liner you already have can no longer be trusted to do its one job: carry hot flue gases out of the house without leaking heat, smoke or carbon monoxide into the structure. That usually means clay tiles that have cracked, shifted or fallen out, a stainless liner that has rusted or split, or a liner that was the wrong size for a new furnace, water heater, insert or stove. We remove or properly abandon the failed liner and install a new, correctly sized stainless steel liner in its place.

Who needs it? Homeowners across King, Pierce and Snohomish counties whose camera inspection shows damage that a spot fix cannot safely address, and anyone who changed a heating appliance and now has a flue that is too big, too small or the wrong material for what is venting into it. If your chimney has never had a liner at all, that is a different service, Chimney Liner Installation. If the liner is damaged in one or two spots and the rest is sound, Chimney Liner Repair may be enough. Replacement is for liners that are past repair.

Timing & Safety

When replacement is necessary versus optional

Replacement is the right call when:

• Multiple clay tiles are cracked through, displaced or missing, so gaps exist along the flue
• A stainless liner is corroded, split or crushed anywhere along its length
• An appliance change left the flue oversized, undersized or made of a material not suited to the fuel
• Repair would only patch one spot while the rest of the liner is in similar condition

Replacement may be optional when:

• Damage is confined to one or two tiles or a single joint and the remainder is sound, which is where Chimney Liner Repair fits
• The flue itself is sound but the masonry around it is failing, which points toward Chimney Liner Rebuild rather than a new liner
• The flue is not in use and will be capped off rather than brought back into service

NFPA 211 recommends an annual inspection of chimneys and venting systems. A Level 2 camera inspection is the standard way to tell a repairable liner from one that needs to come out, and we will never recommend replacement without showing you why.

Safety considerations

A failed liner is not a cosmetic problem. Gaps in clay tile or a corroded steel liner can let heat reach framing, and flue gases including carbon monoxide can migrate into living space. Please keep these points in mind:

• Stop using the fireplace, stove or insert once an inspection has shown liner failure until the new liner is in.
• Keep working carbon monoxide and smoke alarms on every level of the home.
• If you ever smell gas, leave the house and call your gas utility or 911. Gas lines and valves are only serviced by a qualified technician.
• Liner replacement involves working at the top of the chimney and handling heavy, sharp materials. Leave the inspection and the work to a trained crew.
• We do not diagnose liner condition over the phone or from photos; a camera inspection is the only honest way to know.

Seattle & Puget Sound conditions

Puget Sound weather is hard on chimney liners. Months of rain find their way through a worn crown or missing cap and soak clay tiles, and the freeze-thaw cycles we get from Everett down to Tacoma pop the surface off wet tile a little more each winter. Near the Sound, salt air speeds up corrosion on lower-grade or unprotected steel liners. On top of that, many older Seattle homes have had a gas furnace or insert added to a chimney built for a wood fireplace, and the oversized masonry flue runs cool, condenses and eats the tile from the inside. When we replace a liner here, we size it to the appliance and pair it with a sound cap and crown so the new stainless is not facing the same moisture that killed the old one.
