Cracked Firebrick in Century-Old Fireboxes
Historic city fireboxes crack and lose mortar joints over time, exposing the framing behind them to heat. Firebrick and joints can usually be rebuilt without touching the rest of the fireplace.

Local Expertise
Fireplace Service Built for St. Louis Homes
St. Louis fireplaces come in two very different flavors. In the city you have original masonry fireboxes in flats and bungalows — cracked firebrick, crumbling joints, rusted or missing dampers, and decades of converted gas hardware. In the county you have factory-built prefab units from the 1980s through the 2000s with worn refractory panels and ignition parts that fail the week the first cold front arrives.
We work on both. That means firebrick and refractory repair, damper and gas valve replacement, pilot and ignition faults, blower and log service, and the honest answer about whether an old unit should be repaired or replaced. Every visit starts with a look at the actual firebox and venting, not a phone guess.
Warning Signs
Common St. Louis Fireplace Problems
A fireplace that is hard to light, smells, smokes into the room or shows cracked panels is telling you something. These are the conditions we are called out for most.
Rusted or Stuck Dampers
Years of water down an uncapped flue rusts dampers solid. We free or replace the damper and fix the water source above so it does not happen again.
Gas Pilot, Valve and Ignition Faults
Pilots that will not stay lit, clicking igniters and dead remotes are the most common gas calls in the St. Louis area — usually a thermocouple, valve or wiring issue, not a new fireplace.

How It Works
From First Call to Working Fireplace
1. Describe the Problem
Tell us the fireplace type — wood, gas logs, insert or prefab — and exactly what it is doing. That determines the parts and tools we bring.
2. Full Diagnosis
We test the ignition system and gas components, examine the firebox, damper and glass, and check the flue and venting path.
3. Safety First
If we find a condition that makes the fireplace unsafe to run, we tell you before anything else and explain what has to be corrected.
4. Repair & Test
Approved repairs are completed, then the unit is run and tested. We show you the finished work and leave the area clean.
5. Written Documentation
You receive findings, photos of accessible areas and a clear note on what was repaired and what should be watched next season.

Fireplace FAQs
Answers Before You Light It

(682) 217-3577The most common causes are a dirty pilot orifice, a weak thermocouple or thermopile that can no longer hold the gas valve open, or a failing valve or ignition module. Testing the components identifies which one before any part is replaced.
Yes. We service gas log sets, direct-vent and prefabricated gas units, fireplace inserts and traditional masonry wood-burning fireplaces. The diagnosis and repair are different for each, so tell us the type when you call.
No. Cracks in refractory panels, firebrick or mortar joints allow heat to reach materials behind the firebox. The fireplace should not be used until the firebox is repaired or the panels are replaced.
It depends on the unit and the failed component. A pilot or thermocouple repair is a very different job from refractory panel replacement or firebox masonry work. We diagnose the fireplace and give a written estimate before repair work begins.
Annually, before the heating season. Gas units need the ignition assembly, burner, gaskets and venting checked; wood-burning fireplaces need the firebox, damper and flue inspected and the flue swept when deposits require it.
Smoke rollback and odors usually come from draft problems, a partially closed or damaged damper, blockage in the flue, or creosote and debris buildup. We check the firebox, damper and flue together rather than treating the symptom.
Yes. Cracked glass, failed door gaskets and worn seals are common on gas units and inserts. A failed seal affects both efficiency and safe operation of a sealed system.
Yes — 10% off for military, veterans, seniors 65+, police, firefighters and EMTs. Mention it when you call (682) 217-3577.
Usually yes. Cracked firebrick and failed joints are repairable, and a full firebox rebuild is possible when the damage is deeper. We show you photos of the condition before recommending anything.
Most of the time it is a thermocouple, pilot assembly or valve issue rather than a new unit. We diagnose the actual fault and give a written price before doing the work.
