Chimney Relining & Flue Liner Replacement in Seattle, WA

Your chimney's flue liner is its most critical safety component — it contains heat, protects your home's structure from fire, and channels toxic gases out of your living space. When a liner cracks, deteriorates, or is missing entirely, relining is not optional. We install stainless steel, cast-in-place, and clay tile liners built to last decades.

Frequently Asked Questions

How much does chimney relining cost in Seattle? +
Chimney relining in Seattle typically costs $1,500-$3,500 for a standard stainless steel liner, $2,000-$5,000 for a cast-in-place system, and $2,000-$4,000 for clay tile replacement. Gas conversion relining is usually $1,200-$2,500. Exact pricing depends on chimney height, diameter, and whether old liner removal is needed. We provide free detailed estimates.
How do I know if my chimney needs relining? +
The most reliable way is an HD video inspection of the flue interior. Common signs include: pieces of clay tile in the firebox, smoke entering adjacent rooms, a chimney fire (even minor), home built before 1950 with original liner, converting to a gas appliance, or a failed Level II inspection during a home sale. We offer video inspections as a standalone service.
What type of chimney liner is best? +
For most Seattle homes, we recommend stainless steel liners. They're durable, corrosion-resistant, fast to install, and carry a lifetime warranty. Cast-in-place liners are best for structurally compromised chimneys or historic preservation. Clay tile is traditional but more labor-intensive and expensive. We'll recommend the best option for your specific situation during the inspection.
How long does chimney relining take? +
Stainless steel liner installation is typically completed in 1 day. Cast-in-place liners require 2-3 days (including cure time). Clay tile replacement can take 2-4 days depending on chimney height and accessibility. We provide an accurate timeline during the estimate so you can plan accordingly.
Do I need a new liner if I'm converting to a gas fireplace? +
Almost always, yes. Gas appliances require a properly sized liner — usually smaller than the existing wood-burning flue. An oversized flue causes condensation, corrosion, and poor draft for gas appliances. We install aluminum or stainless steel liners specifically sized for your gas insert, ensuring safe and efficient operation.
How long does a chimney liner last? +
Stainless steel liners last 25-50+ years and typically carry a lifetime manufacturer warranty. Cast-in-place liners last 50+ years. Clay tile liners last 50-100 years but are vulnerable to cracking from chimney fires and seismic activity. Regular chimney inspections help monitor liner condition over time.
Is chimney relining required to sell a home in Seattle? +
While not legally required, a Level II chimney inspection is standard during home sales in the Seattle area. If the inspection reveals a cracked, deteriorated, or missing liner, buyers will typically require relining as a condition of sale — or negotiate a price reduction. Getting ahead of this with proactive relining can smooth the sale process.
Can a chimney without any liner be relined? +
Yes. Many older Seattle homes — particularly those built before 1940 — have chimneys that were constructed without any liner. These unlined chimneys are a significant fire and carbon monoxide risk. We can install a stainless steel or cast-in-place liner in an unlined chimney, bringing it up to current safety standards.

The flue liner is the inner channel of your chimney that contains combustion gases and protects the surrounding masonry and house structure from extreme heat. In a properly functioning chimney, the liner prevents carbon monoxide from seeping through mortar joints into your living spaces and keeps the intense heat of a fire from igniting adjacent wood framing. When this liner is cracked, deteriorated, or absent, your chimney becomes a serious fire and carbon monoxide hazard.
Seattle has a large stock of homes built before 1940 — many with chimneys that were constructed with no liner at all, or with original clay tile liners that have cracked and shifted after decades of use and seismic activity. The Nisqually earthquake in 2001 and ongoing minor tremors have damaged countless chimney liners across the Puget Sound region. If your home was built before 1950 and the chimney has never been relined, there is a strong chance the liner is compromised.
At Seattle Chimney Pros, we begin every relining project with an HD video inspection of the existing flue. This camera inspection reveals cracks, gaps, deterioration, and structural shifts that are invisible from outside the chimney. Based on the findings, we recommend one of three relining methods:
Stainless steel liners
are the most popular option and our top recommendation for most Seattle homes. A continuous, flexible stainless steel tube is inserted down the full length of the flue, connected to the appliance at the bottom and capped at the top. Stainless steel liners are durable, corrosion-resistant, fast to install (usually 1 day), and carry a lifetime manufacturer warranty. They work with wood-burning fireplaces, gas appliances, and oil furnaces. For wood-burning applications, we wrap the liner with an insulation blanket to improve draft and reduce creosote formation.
Cast-in-place liners
are a cement-like material pumped into the chimney around an inflatable form. Once cured, the form is removed, leaving a smooth, seamless, insulated liner bonded directly to the existing masonry. This method is ideal for chimneys with structural concerns — the cast-in-place material actually strengthens the chimney from the inside. It is the best option for historic Seattle homes where preserving the exterior appearance is important.
Clay tile liners
are the traditional lining method. Individual clay tiles are stacked inside the flue. While durable and heat-resistant, clay tile replacement is labor-intensive and more expensive than stainless steel. We primarily recommend clay tile when matching existing construction in historic preservation projects.
If you are converting from a wood-burning fireplace to a gas fireplace insert, relining is almost always required. Gas appliances produce different combustion byproducts than wood and require a properly sized liner to vent safely. An oversized flue left from a wood-burning setup can cause condensation, corrosion, and improper draft for a gas insert. We handle the complete conversion — chimney repairs, relining, and appliance connection — as a single coordinated project.
