Fireplace repair and maintenance in North Quarter

A damper that jams partway through its swing

A throat damper should swing from fully closed to fully open without a fight. When it jams partway, the cause can be rust on the pivots, debris sitting on the plate, a bent plate or a frame that has shifted in the masonry around it.

Forcing the handle rarely helps and can snap the linkage. Lighting a fire with the damper half open is also a poor idea, because a damper that is not open wide enough is one of the conditions EPA wood-burning guidance links to smoke hanging in the flue.

Our technician works the plate free, cleans the pivots and checks that the plate seats when closed. If the frame or plate is damaged beyond that, the job becomes a damper repair or replacement, and the estimate says so with the parts named. Whenever we visit a home in North Quarter, the damper is run through its full travel either way, and you are shown both positions.

The passage above the firebox and the flue

Smoke leaves the firebox through the throat, past the damper and into the smoke chamber before it reaches the flue. For a masonry fireplace, the Florida Building Code says that whole passageway cannot be smaller in cross-section than the flue it feeds. When something narrows it, smoke has less room to leave and more reason to turn back toward the opening.

Narrowing can come from a damper that only opens partway, a warped plate, debris on the smoke shelf, fallen masonry or an earlier alteration that reduced the throat. Some of these are fixed from the firebox. Others need smoke chamber or damper work.

From below, we look at the passage and compare the damper opening with the size of the flue. The estimate names what is narrowing the passage and which repair opens it back up, with separate lines for any work above the damper.

Carbon monoxide alarms near the sleeping areas

Fuel-burning fires produce carbon monoxide, and EPA wood-burning guidance warns that it can be released into the home. The U.S. Consumer Product Safety Commission advises a CO alarm on each floor of the house and outside the bedrooms, powered by batteries or with a battery backup. NFPA heating safety tips also call for installing and maintaining them.

If a CO alarm goes off, take everyone out into fresh air and phone 911 from there. Do not go back in to check the fireplace.

Alarms age and batteries run down. Test them the way the alarm maker directs and replace units when their instructions say to. A fireplace that has just been repaired is a good reminder to check the alarms in the rooms around it and in the hallway outside the bedrooms. Keep the alarm instructions with the fireplace records so the replacement date is easy to find.

Fireplaces in rental and second homes

A fireplace in a rental or second home is used by people who do not know it. Guests may build larger fires, burn whatever is handy and leave the damper open or closed at the wrong time, and damage can sit unnoticed between stays.

Owners and property managers usually want a working fireplace, clear rules for guests and a record of what was done. Our crew in North Quarter works with owners and managers directly, including access arrangements when the owner is away.

Repairs are timed around bookings where possible, and anything that makes the fireplace unsafe to use is flagged in writing right away so it can be closed to guests until it is fixed.

• A written record after each visit
• Screens and doors that close properly
• A short fuel and ash note for guests
• Repairs scheduled between stays
