Penetration leaks in Austin: pipes, conduit, and the holes after the trades
Every AC line set, hose bib, and conduit is a hole in the weather plane. This site is those leaks — not windows, not vents, not a full recoating.

Mechanical and electrical punch a wall and leave foam or a smear of caulk. Rain finds it for years.
An AC line set on a south wall cooks the sealant. The stain shows up above a window that is not leaking.
Through-wall scuppers and overflow pipes that were never flashed become indoor waterfalls in a storm.
What to watch for
Small signals can mark a larger hidden path.
- Water at a hose bib, light, or camera box
- Stains under an AC line set
- Conduit or gas pipe through stucco or stone
- A punch list of ‘seal all penetrations’ after other trades left
Field standard
Trace first.
Repair second.
The field plan
Find the cause before pricing the close-up.
Clear scope, honest boundaries, and a repair built around the assembly—not the stain.
AUS / 01
We flash and rebuild the finish at wall penetrations so the pipe can move a little and water still sheds.
We do not re-run your mechanical. We make the hole honest: boot, flange, or soldered flashing, then a finish patch.
If the leak is the window or the bath vent, use those dedicated sites. This door stays on pipes, conduit, and fixtures.

Straight answers
Before we open the wall.
Can you seal around a live AC line?
Yes, with the condenser running. We need access and a shutoff if we have to open the finish deep.
Is spray foam a fix?
No. Foam is not flashing. We remove it when it is holding water.
Do you firestop rated walls?
Rated firestopping is its own trade. We will not stamp a firestop we did not install.
