Chimney Maintenance and Installation Tips

Chimneys are an important part of your home’s architecture. If you’re building a new home or renovating an existing house to install a wood burning fireplace this element needs some serious planning and design. That’s because the installation and maintenance of your chimney will make a big difference in the operation of your wood burning fireplace or wood stove.

Match The Chimney Size To The Hearth Appliance

In simple terms, your chimney flue should be the same size as the flue on your wood stove or fireplace insert. In the case of chimneys, bigger is not better – it only creates an imbalance of airflow. Flue gas will flow up and out faster in a small chimney, producing a healthier, cleaner system.

Keep It Tall

Your chimney should be an absolute minimum of 15 feet tall (from the floor to the exhaust point). Although this isn’t a problem in most homes, make sure your cottage or mobile home system meets this minimum requirement. Taller chimneys actually produce a better system that will allow for easier lighting of the fire and better exhaust. If your chimney is below this
height it could potentially endanger the safety of your family and neighborhood.

Regular Maintenance Is Vital

Keeping your chimney clean is important not only for its operation but for your safety. Chimney fires are common and highly dangerous, mainly caused by creosote build-up. Having a certified technician inspect and clean your chimney at least once per year is essential. The minimal cost will allow you to enjoy cleaner fires that are easier to light and maintain. You can also rest assured that your chimney system is holding up well and stay on top of any necessary chimney repairs.

The services of a knowledgeable chimney technician are valuable. For design, installation and chimney maintenance, get a pro on your side and enjoy your hearth as you were meant to.

How Do You Stop Smoke From Crossing Over From One Fireplace Chimney To Another?

Chimney Repair in Germantown MDIf you have two fireplaces with flues running up the same chimney structure, (like the picture) you are often a candidate for the problem of smoke crossover. Smoke crossover is when one chimney is breathing out smoke from the fire, and the other chimney is breathing in outside air to equalize the pressure in the home. The inhaling chimney flue is also sucking back in smoke from the other nearby chimney.

Many people assume closing the metal damper on the unused fireplace will stop this smoke crossover, but that is not the case. Dampers are not tight enough to stop this air draw. The smoky fireplace needs to be air sealed to stop the smoke. That is why a chimney balloon is needed in the unused fireplace to stop the air draw inward through the second flue.

Chimney flue liner repair in Potomac MDYou would measure your fireplace flue for a chimney balloon and then install that chimney balloon low and tight in the fireplace that is drawing smoke. Air sealing the smoky fireplace with the balloon forces the house to find another location (i.e. windows and doors and other envelope penetrations) to draw outside air in at where there is no smoke. This keeps the fire burning in the one fireplace and keeps the smoke outside where it belongs.

Benefits Of A Stainless Steel Chimney Liner

Chimney liners are a vital element in the operation of your fireplace or wood stove. And when the liner has deteriorated, cracked or aged beyond its limit you have a choice of materials for the replacement chimney liner.

Aged clay tile chimney liners will crack and split, which allows noxious fumes to leak into your home. With a stainless steel liner you will effectively seal those cracks and drastically reduce the chance of them happening ever again.

Added Insulation

This insulation cuts down on creosote build up by keeping the air hot all the way up the chimney. It also helps to reduce the cold air draft that could come down the chimney when the fireplace or wood stove is not in use.
