About Our Allentown, PA Certified Chimney Sweeps

We are a local Allentown, PA team of CSIA-certified (Chimney Safety Institute of America) technicians. Our job is to protect your family from chimney fires. We provide a "no-mess, no-stress" chimney sweep, using professional-grade vacuums and brushes to keep your home spotless. Every cleaning comes with a safety inspection.

The 3 Stages of Creosote (The Danger Scale)

"Creosote" is the tar-like, flammable byproduct of burning wood. Not all creosote is the same.

• Stage 1 (Soot): A light, feathery dust. It's easy to remove with a brush. This is the best-case scenario.
• Stage 2 (Porous & Crumbly): This is a harder, more concentrated deposit. It looks like black, crunchy flakes. This is a clear sign you're overdue for a cleaning and is a serious fire risk.
• Stage 3 (Glazed): This is the most dangerous. It looks like a shiny, black, tar-like "glaze" on your flue. It is extremely flammable and the hardest to remove, often requiring special chemicals.

How Does a Chimney Fire Start?

All it takes is one hot ember to ignite the creosote build-up. A chimney fire can burn at over 2000°F. This can crack your chimney liner, allowing the fire to spread to your home's wooden frame.

Our "No-Mess" Cleaning Process

We are professionals, and we respect your home.

• We lay down tarps and use a high-powered vacuum with a HEPA filter to ensure no dust or soot enters your room.
• We use a system of flexible, rotating brushes to scrub the entire flue, from the firebox to the cap.
• We clean the smoke shelf and damper.
• We provide a Level 1 Safety Inspection with every sweep to check for cracks or blockages.
