Pilot Assembly Replacement in Dallas, TX

That's the signature of a weak thermocouple. It lights, but it no longer makes enough millivolt to hold the gas valve's safety magnet open, so the valve closes the second you stop overriding it by holding the knob. We meter the output (a healthy one reads around 25-30 mV open-circuit) and replace the failed proving part on your existing ignition — it's the most common fix for exactly this symptom.

This replaces a worn part on the ignition system you already have; pilot light installation builds a new system where none works. You're not redesigning how the fireplace lights — you're swapping the thermocouple, thermopile, igniter, or pilot hood that aged out of the existing setup. If there's a working architecture and one dead part, this is the right service.

Because the dropout is usually the cheap proving part, not the valve. A dropping pilot can mean a weak thermocouple (this fix) or, less often, a valve magnet that won't hold even on a healthy millivolt signal (valve work). We meter the thermocouple output and check the valve's hold so we replace the right thing — and confirm it isn't really a clogged orifice or a draft first.

A fresh thermocouple won't fix a clogged pilot orifice, a draft pulling the flame off the sensor tip, low gas pressure, or a failing valve magnet. That's why we re-read the millivolt after the swap and aim the flame to fully envelop the sensor, and replace the full hood-and-thermocouple assembly when the hood and orifice are also worn rather than just the one part.

Almost certainly a factor. North-Texas expansive clay swells and shrinks with our wet-then-drought cycle, and a rigid masonry chimney riding on moving soil develops stair-step cracking through the mortar joints. We diagnose whether it's active settlement or stable historic movement, then repair with crack-stitching or repointing matched to your chimney's era — and we tell you honestly if the cause is foundation-side and needs to be addressed first.

That's spalling — water absorbed into the brick froze during a hard freeze and popped the outer face off. It's a freeze-thaw signature, and in Dallas it's accelerated because our brick takes on water in fall rains and then meets a sudden January freeze. We cut out and reface the spalled brick with a matched replacement and, critically, seal the moisture source with a breathable masonry repellent so it doesn't simply happen again next winter.

Yes — this is exactly where craftsmanship matters. We select the correct mortar strength (soft historic chimneys need lime or Type N, not hard Portland that cracks the brick) and source reclaimed or color-matched brick for out-of-production blends so the repair is invisible. A premium repair on a historic home should disappear, not announce itself.

Because crown sealing and repointing need to cure above freezing and be in place *before* the freeze that causes the damage. In Dallas the smart window is September–October. Repairing after a hard freeze means you've already absorbed a winter of water intrusion — the expensive version of a cheap fall fix.
