What you are seeing, and which service to schedule

Not certain? Call (872) 366-9749 and tell us what is happening.

Smoky odor lingering in the house
We recommend: Chimney Sweeping

A persistent smoke smell typically indicates creosote accumulation or poor airflow. A sweep clears the flue, and we test the draft during the visit.

In the middle of a home sale or purchase
We recommend: Chimney Inspection

A thorough inspection with photos gives you a clear picture of the chimney's condition before closing.

Moisture marks around the fireplace area
We recommend: Masonry Repair

Those marks indicate water is penetrating through the crown, flashing, or masonry. We locate the entry point and seal it.

Wildlife sounds coming from the chimney
We recommend: Chimney Cap Installation

A properly fitted cap with screening permanently prevents animals, leaves, and rain from entering the flue.

Clothes still damp after a full dryer cycle
We recommend: Dryer Vent Cleaning

Slow drying almost always means lint has clogged the vent, which also poses a fire risk.

Smoke leaking from the wood stove
We recommend: Wood Stove Service

Deteriorated gaskets or a soot-filled stovepipe allow smoke to escape. We clean the pipe and replace the seals.
