Chimney Sweep in Diamond Bar
Licensed, CSIA-certified technicians providing expert chimney sweep to homeowners across Diamond Bar and the Pomona Valley.
The right time of year for this
A chimney used steadily through a cold snap collects most of its soot and creosote in a short stretch of weeks, then often sits unused once the weather turns. Leftover creosote left in a flue over a long stretch of warm, dry months has time to absorb moisture from the air and start forming the harder, glazed layer that a simple brushing struggles to remove. Booking a sweep at the end of a burning season, once the last fire has cooled, clears that residue while it is still loose rather than letting it sit through spring and summer. It also gives a technician a chance to flag a damaged damper seal or a cracked flue tile before the chimney goes unused for months, rather than finding it right before the next fire is lit.

BeforeDamper Clamp Installation
Southern California
The existing throat damper plate had corroded and no longer closed fully, allowing constant cold downdrafts and energy loss. Rather than an expensive full damper replacement at this time, we installed a heavy-duty damper clamp that holds the damper plate securely shut. The clamp features a chain release so the homeowner can open it easily before lighting a fire. A cost-effective solution that immediately solved the draft and energy issue.
