Gas Fireplace and Furnace Flue Cleaning in Milwaukee

Gas burns cleaner than wood, but that does not mean a gas fireplace or furnace flue never needs attention. Nests, leaves, debris and deposits can build up in a flue and keep exhaust from venting properly. The Chimney Expert cleans gas fireplace and furnace flues throughout Milwaukee, Waukesha and Washington counties.

Our focus is cleaning the venting so exhaust can leave your home the way it should.

Call (414) 350-4263 or contact us online to schedule. Hours: Monday to Friday 9 to 5, Saturday 9 to 3.

Why Gas Flues Need Cleaning

A gas appliance relies on a clear flue to carry exhaust out of the house. Over time, flues can become restricted by:

Bird and animal nests
Leaves and windblown debris
Loose mortar or flue tile pieces
Soot and deposits that build up inside the flue
Moisture-related debris from condensation

A blocked flue can cause poor draft and odors. Keeping it clean helps your fireplace or furnace vent as intended.

Gas Fireplace Cleaning

When we clean a gas fireplace venting system, we clear the flue of debris and blockages, check the cap at the top, and take a look at the chimney exterior for problems such as worn mortar or damaged flashing. We protect your floors and use a HEPA vacuum so dust and debris stay out of your living space.

Our work is cleaning the venting. For repairs to the gas appliance itself, such as the burner, valve or ignition, contact your gas appliance service provider.

Furnace Flue Cleaning

Many older homes vent the furnace and water heater through a masonry chimney. These flues can collect debris and deposits, and they are easy to forget because you never see them. We clean furnace flues and check for blockages, and if we find a problem with the chimney itself, such as damaged masonry or a missing cap, we explain it and provide a written estimate for repair.

Signs Your Gas Flue Needs Attention

Odors when the fireplace or furnace runs
Visible soot around the fireplace opening or vent
Signs of nesting or animal noises in the chimney
Debris on the furnace or water heater vent connection
A missing or damaged chimney cap
It has been a long time since the flue was cleaned

If you ever suspect carbon monoxide, leave the home and call your gas utility or 911 right away.
