Plain-language answers to the questions we actually get asked, before anyone talks about a repair.

Why Does My Chimney Only Leak When It Rains Hard?
If your St. Louis chimney only leaks during hard, wind-driven rain, the cause is almost always a small gap that light rain never finds and enough water hits it — a cracked crown, a lifted piece of flashing, or a mortar joint that's opened up. It is rarely a sign the whole chimney is failing, but it will get worse every time it happens.
Why Won't My Gas Fireplace Light — or Why Does It Keep Shutting Off?
A St. Louis gas fireplace that won't light, or one that lights and then shuts itself off within a few seconds or minutes, almost always comes down to one of three things: a weak thermocouple or thermopile no longer proving a flame is present, a dirty or misaligned pilot assembly, or a safety sensor correctly detecting a real problem with the burn or the venting. None of the three is a sign you need a new unit, but they're not the same repair — and they're not something to keep re-lighting and hoping.
Why Does My Chimney Smell Like Smoke in the Summer?
A St. Louis chimney that smells like smoke in summer is doing three things at once: creosote is still lining the flue, humid Missouri air is soaking into it and reactivating the odor, and your air conditioning is lowering the pressure inside the house enough to pull that air down the chimney and into the room instead of letting it rise. The smell was there all along. Summer just gave it a way in.
Does a Gas Fireplace Really Need Annual Service?
Yes, and for the opposite reason most St. Louis homeowners assume. A gas fireplace is not maintenance-free because it is clean — it needs checking precisely because it is clean. With a wood fire you can see soot and smell smoke when something goes wrong. A gas appliance venting badly gives you no warning at all, because carbon monoxide has no colour and no smell. Annual service is how that gets caught.
