Chimney Cleaning, Furnace Flue Cleaning

Chimneys are swept to remove residues in the chimney which can block the flue and prevent proper drafting, and to remove flammable deposits which can cause a chimney fire. Wood smoke occurs because not all the chemicals in wood can be burned by your fireplace or wood stove. Smoke contains tiny, unburned but flammable solid particles which adhere to the walls of your chimney which are called creosote. As these deposits accumulate, a stray spark from your fire can ignite them causing a chimney fire.

Flue Caps

Flue caps are needed to reduce moisture, keep out animals, block downdrafts, stop sparks and embers, and prevent debris build-up. 

Safety Inspections, Humane Animal Removal

The N.F.P.A. (National Fire Protection Association) Code 211 Chapter 14.2 states “Chimneys, fireplaces, and vents shall be inspected at least once a year in accordance with the requirements of Section 15.2” Inspections detect “unseen” hazards. Your chimney/fireplace may look fine on the outside to the untrained eye, but cracks or missing mortar, etc. that may appear to be insignificant can be very hazardous. The inspection aspect of chimney cleaning is very important for you and your family’s safety and peace of mind.


  • Lining your chimney creates a continuous smooth chimney with less surfaces for tar / soot to condense onto. Tar that does form can flow directly back to the stove to be recombusted as opposed to building up in the rough crevices of a masonry chimney.
  • Lining your chimney will cure problems of smoke leaking out through cracks in a masonry chimney.
  • Lining your chimney will stop new tar from leaking out through cracks in the chimney or onto your stove.
  • Containing the flue gases in a pipe of consistent diameter maintains the flow and velocity of the gases in the system - ie the flue gases will travel faster. This will reduce deposits (as the gases spend less time in the chimney and cool less) and will also improve draw.

Damper Repair

Huge heat loss occurs when a chimney damper does not seal properly, is missing, or broken. You can't see it but the heat goes out of the house. It's like leaving your window or front door open in the winter. 

Chimney Repair

The chimney crown is an important part of the chimney system. It is the area around the top of the chimney that acts as an umbrella for the entire chimney structure. The chimney crown is not to be confused with the chimney cap, which is an attachment that is added to the top of the flue pipe to keep debris out of the chimney flue. The chimney crown tops off the masonry walls of the chimney with a small concrete roof that prevents water from seeping into the bricks and mortar that make up your chimney. This simple structure can actually save homeowners thousands of dollars in costly water damage repairs.If a chimney crown becomes cracked or damaged, water and moisture can seep into the vulnerable masonry material of your chimney system and start deteriorating from the inside out. Repair or sealing is the best solution for a failing chimney crown and can save you from dealing with costly structural chimney repairs that could occur if the problem is neglected.

Wood Stove Installation

Installing a wood stove in your house can be a wonderful decision for improving your overall atmosphere and heating energy efficiency in your home. Hopefully, you have looked at all the parameters: venting system placement, vent system compatibility, height of the chimney system, proper clearance, size and floor protection. If not, then it is time to call in someone who has the experience, skill and technical knowledge needed to get this project moving in the right direction. That’s where we come in. The first and most important part of the process is determining the type of chimney system you have.
