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 off the flue wall. A standard sweep, by comparison, is brush-and-rod cleaning meant for soft Stage 1-2 buildup. We reserve deep cleaning for deposits that have baked past anything a brush can reach.

Glazed creosote reads shiny, hard, and tar-like instead of powdery, and a brush just slides across it. Before choosing a method, we grade the buildup with a camera scope: if it's soft Stage 1-2, a routine sweep is all you need and we'll tell you so; if it's Stage-3 glaze, only rotary tooling paired with a PCR poultice will genuinely clear it, and a normal sweep would just waste your money.

It's the deposit behind most serious chimney fires, concentrated fuel fused right to the flue wall. The standard guidance, echoed in NFPA 211, is to stop burning until heavy glaze is cleared, because a single hot or overfired burn can ignite it and let the fire spread into the structure. That's 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 comes away as the paste is removed. We turn to it when glaze is too hard, thick, or deeply fused to knock loose with rotary heads alone, or on clay tile, where relying on the poultice avoids the cracking that over-aggressive chain knocking can cause. Most deep cleans call for both: rotary to break up the bulk, poultice for the stubborn remainder.

Only when the wrong head gets used. Matched to your liner, controlled speed and a poultice on clay tile, poly (never steel) flails on a stainless liner, it strips glaze without doing harm. Reach for the wrong head or push it too hard and you can crack tile or gouge a metal liner, which is exactly why a trained tech handles it with liner-matched tooling instead of rental equipment.

Often, yes, though thick, layered glaze can call for a second poultice pass between visits to break it down completely. A post-clean camera scope verifies 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 can't safely clear it, we'll tell you straight that relining is the honest next step rather than grinding tile we might crack.

That's the whole design of it. Older homes interconnect in ways separate contractors miss — the chase that carries your original flue often carries duct runs and wiring too, and an uninsulated attic changes how the entire house breathes. We inspect chimney, ducts, dryer vent, and insulation in one pass and write it up as one prioritized report, so you're not reconciling four different opinions.

Maybe — many pre-war flues here are unlined or have cracked clay tiles, and you can't tell from the hearth. A camera inspection settles it in about twenty minutes. If it's sound, we document that and sweep it. If it needs a liner, we price it plainly and tell you what's safe in the meantime, which is sometimes nothing until it's fixed.

Inspection first, always — it sets the sequence. Typically: chimney safety items before burn season, attic air-sealing and insulation in spring or summer when it pairs naturally with duct sealing, and the dryer vent the same day as everything else since it takes the least time. Masonry repairs cure best in warm, dry months, so we slot those accordingly.
