Deep Chimney Cleaning (PCR) in Alamo Heights, TX

PCR stands for Poultice Creosote Removal, a chemical paste troweled onto hardened glaze to soften it and lift it away. Deep cleaning combines that poultice with powered rotary tooling, chain knockers and flails on a drill-driven shaft, to strip glassy Stage-3 creosote from the flue wall. A standard sweep, by comparison, is brush-and-rod work for soft Stage 1-2 buildup. We reserve deep cleaning for deposits baked beyond anything a brush can reach.

Glazed creosote reads shiny, hard, and tar-like instead of powdery, and a brush simply slides over it. We scope the buildup with a camera before choosing a method: soft Stage 1-2 means a routine sweep, and we will tell you so; Stage-3 glaze means rotary tooling and a PCR poultice are the only things that will genuinely clear it, and paying for a normal sweep would be money wasted.

It is the deposit behind most serious chimney fires, concentrated fuel fused onto the flue wall. Standard guidance, echoed in NFPA 211, is to stop burning until heavy glaze is removed, because a single hot or overfired burn can ignite it and let the fire spread into the structure. That is why we treat deep cleaning as a stop-and-fix job rather than routine upkeep.

The poultice is a chemical compound troweled onto the worst glaze and left to dwell, where it softens and absorbs the creosote so it releases as the paste comes off. We turn to it when glaze is too hard, too thick, or too deeply fused for rotary heads to knock loose on their own, or on clay tile, where relying on the poultice avoids the cracking that over-aggressive chain knocking can cause. Most deep cleans use both: rotary to fracture the bulk, poultice for the stubborn remainder.

Only when the wrong head is used. Matched to your liner, controlled speed with a poultice on clay tile, poly flails (never steel) on a stainless liner, it strips glaze without harm. The wrong head or too-aggressive use can crack tile or gouge a metal liner, which is precisely why a trained tech with liner-matched tooling does this, not rental equipment.

Often yes, though thick, layered glaze occasionally needs a second poultice pass between visits to break down fully. A post-clean camera scope confirms the flue is back to bare liner before you burn again, and if the glaze turns out so fused that even rotary tooling and a poultice cannot safely clear it, we will tell you relining is the honest next step rather than grinding tile we might crack.

Usually not. Powdery joints in pre-war masonry mean the lime mortar's reached the end of its service life, not the brick. We grind out the failed joints by hand, repoint with a matched lime blend, and rebuild only what's structurally gone. You get photos of every joint we cut before we cut it. Full rebuilds on sound 1920s brick are rare, and we'll say so when yours doesn't need one.

Two reasons. Strength: modern portland mortar is harder than 1920s brick, and hard mortar forces movement into the brick face, which spalls it. Appearance: a gray smear across cream-colored lime joints reads like a scar on a house this age. We match the binder, the sand color, and the joint tooling, so the repair disappears and the brick keeps doing the moving it was designed to do.

Sometimes. Age alone doesn't fail a flue — cracks, gaps, and eroded mortar joints between tiles do. The 2021 freeze split plenty of old tiles in this neighborhood, and you can't see that damage from the firebox. We run a camera up the flue, document every tile, and hand you the images with the written report. If it's sound, we say sound.
