Certified Chimney Sweep

Annual chimney sweep services are recommended by virtually every fire-safety organization in the U.S. Why? Because when wood burns, a flammable substance called creosote forms and adheres to the liner or chimney walls. The more creosote, the more chance for a potentially dangerous chimney fire. Chimney cleaning also takes care of obstructions like falling debris from trees and small-animal nests that can hamper drafting and send smoke and toxins back into the home. Our chimney sweeps are certified through the Chimney Safety Institute of America.

Merrimack, NH, Chimney Inspections

A thorough chimney inspection is the best way to spot early signs of damage or deterioration within the chimney system and get it fixed before it becomes a costly problem. We perform all levels of inspection:

Level 1: Basic inspection covering visible components and the chimney structure

Level 2: Performed during real estate transactions, when attaching a new appliance to the chimney, or following a chimney fire

Level 3: In cases where significant damage has been uncovered during a previous inspection

Leaky Chimneys

Chimneys can leak for a variety of reasons. Have you noticed these leaky chimney signs?

  • Unpleasant odors in the room
  • Dampness on walls close to the chimney
  • Discolored chimney masonry
  • Water on the floor of the firebox

Damage to chimney components or to the chimney itself can allow water into the system, where it will begin a cycle of decay and rotting. If a chimney is obviously leaking, it’s likely in an unsafe operational state. Count on our CSIA-certified technicians to find the source of any leak and get it fixed quickly.

Chimney Masonry Repair

Damaged masonry should be addressed and fixed as soon as the problem is identified. The point of our chimney masonry repair service is to restore strength to the structure and to prevent water from infiltrating the system and causing major damage. If sections of bricks are falling away, we often can perform a process known as tuckpointing to fill empty sections of masonry with a strong compound that will add strength and life to your chimney. For minor cracking, we can apply a waterproof sealant to block water. Our CSIA-certified masons perform all levels of chimney masonry repair including historic chimney restorations.
