Masonry or factory-built: know your wood fireplace
Wood fireplaces come in two very different forms. A masonry fireplace is built on site from brick or stone, with a chimney to match. A factory-built fireplace is a metal unit lined with refractory panels. It vents through a listed metal chimney that's usually hidden inside a framed chase. The quickest clue is inside the firebox: factory-built units generally have a metal rating plate and molded panels instead of laid brick.
| Feature | Masonry | Factory-built |
|---|---|---|
| Construction | Brick or stone firebox and chimney built on site | Metal firebox with refractory panels and a listed metal chimney |
| Typical wear | Cracked firebrick, eroded mortar, crown and flashing leaks | Cracked panels, rusted chase covers, damaged chimney sections |
| Usual fixes | Firebox repair, tuckpointing, crown repair | Refractory panel replacement, chase cover replacement, prefab chimney and chase repair |
| Replacement parts | Matched by material and size | Must match the manufacturer's listing for that unit |

That last row matters. Mixing parts on a factory-built unit can compromise its safety listing, so we work from the rating plate when ordering panels or chimney components.
Restoring an older wood fireplace
Many wood fireplaces aren't broken so much as tired: a smoke-stained face, a damper propped open for years, doors that no longer close. Restoration brings them back into working order. The work often starts with clearing out years of soot and creosote, then moves to the firebox, damper, smoke chamber and glass doors as needed. If a factory-built firebox has failed beyond repair, we also handle prefab fireplace replacement.
When a wood fireplace isn't the right fit anymore
Sometimes the question isn't how to fix the fireplace but whether it still suits how you live. Maybe you rarely light fires because of the hauling and cleanup, or the room stays cold when you do. There are other directions:
- Add an insert. A sealed wood or gas fireplace insert fits the existing opening and heats far better than an open fire.
- Convert to gas. A fireplace conversion with gas logs or a gas insert keeps the look and adds push-button convenience. We run the gas line too.
- Start fresh. If you want a real wood fire where there's never been one, look at new wood fireplace construction.

What happens during the visit
Cracks in the firebox let heat reach the framing behind it. A damaged smoke chamber is a common cause of smoke spilling into the room.
Find the cause
The firebox, damper, smoke chamber and any doors, glass or panels are checked.
Confirm the type
Masonry or factory-built — the repair has to suit the system.
Explain the fix
You hear the options and what each involves before work starts.
Repair and test
The work is done and the fireplace is checked before you use it.
If smoke comes into the room
Stop adding fuel, open a window and don't relight the fire until the chimney has been checked. If the smoke is heavy, an alarm sounds or you suspect a chimney fire, get everyone outside and call 911.
Getting ready for the visit
- Clear a few feet of space in front of the hearth or appliance.
- Keep pets in another room while the work area is open.
- Move rugs, photos and anything fragile away from the work area.
- Write down what you've noticed and when it happens — smells, smoke, sounds or stains.
What gets checked
- Doors, glass and gaskets
- Mortar joints inside the firebox
- Damper operation
- Hearth and surround
- Draft from the opening
- Firebrick or refractory panels
When to book wood-burning fireplace repair
- Cracked or missing firebrick or refractory panels
- A fireplace that is hard to light or won't stay lit
- Rust or warping inside the firebox
- Doors or glass that are cracked or don't seal
- Smoke coming into the room
