A working fireplace needs four things in good order: a sound firebox, a damper that opens and seals, a smooth smoke chamber and a flue that is intact and the right size. In Richmond's older homes one or more of these has usually been compromised by a century of use, by settlement or by an old repair done poorly. Fireplace repair means finding which, and deciding whether the fireplace should be restored for open fires or fitted with something better suited to it.

  • Firebrick and refractory mortar joints repaired
  • Smoke chambers parged smooth for better draft
  • Dampers repaired, or replaced with top-sealing dampers
  • Gas log sets, pilots and valves serviced
  • Stoves and inserts fitted with correctly sized liners

Can an old coal fireplace burn wood?

Often not as it stands. Fireplaces built for coal are shallow and small, with narrow flues, and many were never lined. A wood fire in one can spill smoke into the room and overheat an unlined flue. The usual answers are a gas or electric insert sized for the small opening, or a wood-burning insert with a full stainless liner, once an inspection confirms the structure is sound. A sweep can tell you which your fireplace will accept.

Why a fireplace smokes

Smoke in the room means the draft is not carrying it up. Common causes are a cold flue on an outside wall, a closed or stuck damper, a flue too small or too large for the firebox opening, a blockage such as a nest, a chimney that is too short, and a house so tightly sealed, or with fans so strong, that air is pulled down the chimney. The cure follows the cause: sometimes a taller flue or a smoke guard, sometimes a top-sealing damper, sometimes just a cracked window when lighting.

Gas logs and inserts

The frequent gas faults are a pilot that will not stay lit, usually a worn thermocouple or a dirty pilot orifice, and logs that soot because they have been moved from their designed positions. Vent-free gas logs burn room air and release their exhaust into the house; they should be serviced yearly, used only as the manufacturer directs and paired with a working carbon monoxide alarm.

Common fireplace repair situations in Richmond

  • A fireplace that fills the room with smoke
  • Loose or missing firebrick and open mortar joints in the firebox
  • A damper rusted open, rusted shut or missing
  • A sealed fireplace the owner would like to use again
  • A gas log pilot that keeps going out

Fireplace Repair FAQs

Is it cheaper to repair or replace a gas fireplace?

Repair, in most cases. Sensors, valves, switches and log sets are replaceable parts, and Angi puts routine gas fireplace maintenance at $80 to $130 before parts. Replacement makes sense when the firebox is corroded or cracked, parts are no longer available or you want a more efficient sealed unit.

What is the most common problem with a gas fireplace?

A pilot light that will not stay lit. The thermocouple or thermopile that proves the flame wears out, or the pilot opening clogs with dust after months of disuse. Both are routine repairs.
