What Is Creosote Buildup — and Why It’s a Serious Fire Hazard
Creosote is a leading cause of chimney fires in New England homes. Here’s what it is, why it builds up, and how to keep it under control.

We’re a family-minded chimney company serving Greater Boston with cleanings, inspections, repairs and liners. Our reputation is built on showing up on time, explaining things clearly, and leaving your home spotless.
Your pets are home all day – and they breathe faster, sleep lower to the ground, and can’t open a window when the air turns bad. That makes dogs and other animals far more sensitive than people to carbon monoxide, smoke and fine soot. A cracked liner, blocked flue or weak draft pushes those right into the rooms your pets live in. Keeping your chimney clean, sealed and properly vented protects everyone under your roof – two-legged and four-legged alike.

A clean chimney isn’t just safer – it looks it, too. Here’s a look at recent before-and-after work.
