A technician-led process that starts with looking
We start with a look
Before anyone talks repairs, we inspect the crown, cap, flue, flashing, and firebox — often with a camera — so the plan is based on what's actually there.
We explain what we found
You get a plain-language read with photos: what's fine, what to watch, and what genuinely needs work. No pressure, no invented problems.
We do the work right
We match materials to your masonry, fix the water source not just the symptom, and clean up after ourselves.
We keep it on record
Photos and notes give you a baseline, so next year's changes are easy to spot and plan around.
The clues that your chimney needs attention
Most chimney problems announce themselves if you know what to look for. Notice any of these? It's worth a look before the season.
Water stains on walls or ceilings
Brown rings near the chimney chase usually mean water is getting past the crown, cap, or flashing.
Smoky odors indoors
A sharp, tarry smell on warm or humid days often points to creosote in the flue.
Loose or crumbling mortar
Gaps in the joints let water in and speed up freeze-thaw damage.
Damaged crown or cap
A cracked crown or missing cap is an open door for rain, snow, and animals.
Smoke backing into the room
Draft problems can come from blockages, sizing, or a cold flue and need diagnosis.
Rust on the damper or firebox
Rust is a moisture clue — it tells us water has been sitting where it shouldn't.
Cracks in the firebox
Cracked panels or firebrick can expose combustible framing and need attention.
Real technicians, on your roof and at your hearth
Chimney Prime has been working on Missouri chimneys since 1998. The photos on this site are our own crews on real jobs — sweeping flues, running camera inspections, rebuilding brick, and setting caps and covers across both metros.
We treat your home like we'd want ours treated: drop cloths down, honest findings, and work that's built to last a Missouri winter.
More about Chimney Prime →Freeze-thaw is hard on a chimney
Missouri winters swing above and below freezing again and again. Water soaks into a crack or an open mortar joint during a wet stretch, freezes overnight, and pries the masonry apart a little more each time. Repeat that dozens of times a winter and a hairline crack becomes a real repair.
Add humid summers, wind-driven storms, and decades-old brick, and you've got the conditions we work in every day. That's why we chase the water source and protect sound masonry with breathable waterproofing — not just patch the symptom.
Start with an inspection →What water finds first
- Cracked crowns with little or no overhang
- Washed-out mortar joints on the weather side
- Rusted or missing caps over an open flue
- Lifted or tar-patched flashing at the roofline
- Spalling brick where water has already gotten in
