What refractory panel replacement involves
Most factory-built (prefab) wood-burning fireplaces have a firebox lined with molded refractory panels instead of laid firebrick. There is usually a back panel and two side panels, and sometimes a floor panel. The panels shield the metal firebox and its surroundings from the heat of the fire. They are designed as wear parts, so they can be replaced without replacing the fireplace.
Replacement means taking out the damaged panels and installing new ones made for that specific unit. The new panels have to match the dimensions and fit of the originals, because the fireplace was tested and listed with those parts in place. Generic boards cut to size are not a substitute. Many gas fireplaces also have panels lining the firebox, and our gas fireplace work covers those units too.
Signs your firebox panels need replacing
Fine surface cracks are common in refractory panels after many heating and cooling cycles, and they don't always mean a panel has failed. Replacement is usually needed when the damage goes deeper than the surface:
Common reasons to replace a panel
- Cracks that have opened into gaps or that go all the way through the panel
- Pieces breaking off, or a panel that crumbles or flakes when touched
- Missing sections or corners, especially low on the back panel where logs rest
- Metal of the firebox visible behind or between panels
- A panel that has shifted, bowed or come loose from its retaining clips
- Damage from logs being thrown in or from a grate pushed against the back wall
Your owner's manual usually describes how much cracking the manufacturer accepts. If you can't find the manual, we can check the panels at the visit. Panels are sometimes only one of several problems, such as a damaged damper, failed seals or other worn parts. In that case broader fireplace repair work may make more sense than swapping panels alone.
Don't burn with exposed metal
If a panel is missing or you can see the metal firebox through a gap, stop using the fireplace until it has been repaired. The panels exist to keep direct fire off that metal.
What the visit involves, step by step
How a panel replacement visit goes
Look at the firebox
We examine each panel and the firebox behind it. We also check the nearby parts, including the grate, the damper and the doors.
Identify the unit
We read the fireplace's data plate for the make and model, so the replacement panels match what the unit was built with.
Explain what we found
You get a free estimate. It covers which panels need replacing and whether anything else needs attention.
Remove the old panels
We release the retainers, take out the damaged panels and clean out the debris and ash behind them.
Fit the new panels
We set the new panels in the correct order, secure them with the retainers and check that they sit tight against the firebox.
Final check
We confirm the grate sits clear of the back panel. Then we go over how to load fires so the new panels last.
Brands, models and related parts
We work on all major fireplace brands. Panel fit depends on the exact model, not only the brand. If the glass or doors on the same unit are cracked or don't close properly, we can handle them at the same visit through our glass and door repair for fireplaces. Doors that seal properly help keep embers and logs from hitting the panels.
Sometimes the panels aren't the real problem. The firebox behind them can be warped, rusted through or otherwise damaged, or matching parts may no longer be available for an older unit. In those cases we will explain whether replacing the whole prefab fireplace is the more sensible option.
Helping new panels last
- Set logs on the grate gently instead of tossing them toward the back wall.
- Keep the grate in the position the manufacturer specifies, clear of the back panel.
- Build fires of a size the fireplace is designed for.
- Don't scrape the panels hard when removing ash. Use a soft brush.
