A chimney liner is the protective channel inside the flue that carries combustion gases up and out. Liner failure is one of the most dangerous chimney problems — combustion gas can escape into wall cavities and ignite the wood framing. — Texas Service Experts Texas Service Experts handles this work across the Dallas-Fort Worth Metroplex following NFPA 211 standards.

What’s actually involved
Chimney liner installation replaces a damaged or undersized flue with a stainless steel liner sized to the appliance. It’s the standard fix for: cracked clay tiles, oversized flues for new gas appliances, post-chimney-fire repair, and converting an unlined masonry chimney to use a wood stove or insert.
The three liner types: clay tile (original masonry), cast-in-place (poured), and stainless steel (most common modern install). We install stainless for almost all repair scenarios — it’s the most flexible, longest-lasting, and code-acceptable option.
Sizing is critical: a liner too large for the appliance creates condensation, draft problems, and creosote; too small creates back-drafting and CO risk. We size to manufacturer spec for the specific appliance.
Insulation around the liner (when called for) improves draft, reduces condensation, and is required for some installations. We include it when needed and explain when it’s not.
Why this matters in DFW specifically
DFW homeowners often discover liner problems after a Level 2 inspection (often triggered by a real-estate sale or post-storm). Older masonry chimneys (1960s-1980s) have clay tile liners with mortar joints that erode after 30-40 years; the cracks are invisible from inside the house but show clearly on a video flue scan.
Our process
- Level 2 inspection (video scan) — Required to scope liner work. Documents existing liner condition and sizes the new liner correctly.
- Liner selection — Stainless gauge and diameter sized to appliance specs. Insulated or non-insulated based on install type.
- Installation — Pull old liner if applicable, install new stainless from top down, secure at top and bottom with appropriate fittings.
- Final test + documentation — Smoke test and Level 1 inspection of completed work; photos and warranty.
Materials and standards
All chimney liner installation work follows NFPA 211 (the National Fire Protection Association standard for chimneys, fireplaces, vents, and solid-fuel-burning appliances) and CSIA (Chimney Safety Institute of America) protocols. Our technicians carry general liability insurance and workers’ comp.

Frequently asked questions
Do I need a liner if my chimney has clay tiles?
Only if the tiles are damaged. A Level 2 inspection (video scan) shows the tile condition. Intact tiles don’t need replacement.
How long does a stainless liner last?
20-50 years depending on alloy (304 vs. 316L), wood vs. gas use, and creosote management.
Why does the liner need to be sized to the appliance?
Mismatched sizing causes condensation, creosote, draft problems, and CO risk. Manufacturer specs aren’t optional.
Can I use my existing chimney for a wood stove insert?
Usually yes, with a properly sized liner. We do this conversion regularly.
Do you handle the permit for liner work?
When required by jurisdiction, yes. We pull and close out permits.
