Cast-In-Place Liner

Cast-in-place is the relining method for a chimney whose flue is not merely unlined but deteriorating — spalled tile, open joints, missing mortar between the wythes. A former is centered in the flue and a lightweight refractory mixture is pumped in around it from the bottom up. When it cures and the former is withdrawn, the chimney has a seamless, insulated masonry liner bonded to the existing structure. It reinforces the stack rather than just passing through it, and it takes odd flue shapes no manufactured liner will fit. We perform this ourselves with our own equipment. Chimney height, flue cross-section, the number of offsets, and how much prep the old flue needs are what move the price.

What is it

What is cast-in-place liner?

Cast-in-place is the relining method for a chimney whose flue is not merely unlined but deteriorating — spalled tile, open joints, missing mortar between the wythes. A former is centered in the flue and a lightweight refractory mixture is pumped in around it from the bottom up. When it cures and the former is withdrawn, the chimney has a seamless, insulated masonry liner bonded to the existing structure. It reinforces the stack rather than just passing through it, and it takes odd flue shapes no manufactured liner will fit. We perform this ourselves with our own equipment. Chimney height, flue cross-section, the number of offsets, and how much prep the old flue needs are what move the price.

Every cast-in-place liner includes:

  • Flue cleaned and prepped, obstructions and loose tile removed
  • Former centered and refractory mixture pumped from the bottom up
  • Seamless insulated liner bonded to the existing masonry
  • Cure monitored, former withdrawn, top and base finished
  • Post-cure camera scan documenting the finished bore

Scoped from a graded inspection

At Space Fireplace Services, a cast-in-place liner is never guesswork. We scope every job from a graded, photographed inspection first — the NFPA 211 level the evidence calls for — so the work is matched to what your flue and masonry actually need, with the report to prove it. The documented inspection is the record the cast-in-place liner is built on.

FAQ

Common questions about cast-in-place liner.

How often should the chimney behind a fireplace be swept?

Plan on a Level 1 inspection every year — that's the NFPA cadence — with an actual sweep once buildup reaches 1/8" of creosote. For a fireplace you light through the season, that usually lands at once a heating season. Think of it as the upkeep that keeps the centerpiece of the room clean, drawing well, and ready to look its best.

Are the people working on my fireplace certified?

Yes. The inspectors who assess your chimney hold current CSIA (Chimney Safety Institute of America) certifications — you can confirm them in the CSIA member directory at csia.org — and our fireplace installations are handled by NFI specialists. The craft that makes a hearth a showpiece starts with the people standing in front of it.

Can you come out fast when something goes wrong?

Yes — emergency response is available 24/7 (subject to crew availability) for active water leaks, an animal trapped in the flue, post-fire damage, and storm damage, same-day in most cases. A fireplace is the heart of a room; when it's at risk, we treat it that way.

Will I see a written quote before any work starts?

Always. You get a written quote before a single tool comes out, with photos of exactly what we found. Final pricing tracks the chimney's real condition and anything additional the inspection surfaces — no surprises, just a clear picture of what your fireplace needs.

Is there a maintenance plan that keeps it all on schedule?

Yes — our annual maintenance membership runs $19.99/month ($240/year) and covers a yearly Level 1 inspection and sweep ($248 value), priority scheduling, 10% off all repairs, and emergency-response priority. Cancel anytime, no contract. It's the quiet way to keep your hearth looking and working its best year after year.
