The liner is the part of the chimney that does the actual work of containing the heat and the combustion gases and steering them safely up and out, and when it fails, the chimney stops being safe to use no matter how good the brick looks. Moss Chimney Sweep replaces chimney liners across Chino, CA, matching the new liner to your specific fireplace, stove, or gas appliance and installing it so the system vents the way it must. A camera scan tells us whether your liner has genuinely failed, and we will only recommend replacement when the footage shows it is truly needed.

- Footage and a written quote before any work starts
How a liner fails, and why the camera settles it
A flue liner is built to take the heat, the moisture, and the acidic byproducts of combustion and keep them off the surrounding masonry and out of your home, and over time those very forces wear it down. Clay tile liners crack and shift, often from the repeated expansion and contraction of heating and cooling, and around here that thermal cycling is severe given how the chimney swings between scorching summer exposure and the occasional hot fire. Metal liners corrode, especially when a gas appliance has been venting acidic condensate through a liner that was never sized for it. Either way, once the liner is compromised, heat and gases can reach the masonry or leak into the house, and the chimney is no longer safe to fire.
The trouble is that none of this is visible from the firebox, which is exactly why we settle the question with a camera rather than a guess. We run the video the length of the flue and read the liner directly, looking for cracked or displaced tiles, gaps at the joints, corrosion, and any spot where the liner has stopped doing its job. You see the same footage we do, so when we say a liner needs replacing, you are looking at the evidence yourself, and when we say it is still sound, you have the same proof in hand. We do not recommend relining a chimney the camera shows is fine.
Matching the liner to what the chimney actually vents
A liner is not one-size-fits-all, and getting the size and type right is most of what separates a relining that works from one that creates new problems. A wood-burning fireplace, a wood stove insert, and a gas log set each need a liner suited to what they produce and how hot they run, and a liner that is too large for the appliance drafts poorly and lets gases cool and condense, while one that is too small chokes the system. This matters a great deal in Chino's newer homes, where we frequently find gas log sets that were dropped into a fireplace and vented through the original oversized flue, which never worked properly to begin with.
We size the new liner to the actual appliance and install a stainless or otherwise code-appropriate system built to last, sealed and supported the way it should be rather than simply dropped in. When the work is done the chimney vents the way it is supposed to, the masonry is protected from the heat and gases it was never meant to contain, and the fireplace or appliance is safe to use again. We explain the options and the reasoning so you understand what you are paying for, not just what it costs.
Only when it is genuinely needed
Relining a chimney is a real piece of work, and it is not something we suggest lightly or to pad an invoice. It is the right call when the camera shows a liner that has truly failed, when a liner is missing or unsafe, or when you are switching appliances and the existing liner no longer matches what you intend to vent. In those cases a new liner is what makes the chimney safe to use, and skipping it is not an option we would put in front of you, because a compromised liner is a genuine hazard, not a cosmetic flaw.
When relining is not needed, we will say so plainly. If your liner is intact and doing its job, you will hear that, with the footage to prove it, and we will move on to whatever the chimney actually requires instead. That is the same standard we hold on every service we offer. We recommend the work the evidence supports and nothing more, because the honest call is what keeps a Chino homeowner calling us back and sending their neighbors our way.
