What our chimney leak repair includes
Every chimney leak job starts with a full inspection and ends with a water test.
Work order
Chimney Leak Repair- Full chimney and attic inspection: We inspect the chimney from the roof and the attic side, checking flashing, cap, crown, mortar joints and the surrounding roof plane. Moisture meter and infrared thermal imaging confirm where water is actually sitting.
- Flashing rebuild and sealing: Failed step flashing and counter-flashing get removed and replaced with new metal, set with butyl tape and sealed with Henry Company or Sika roof sealant matched to your roofing material.
- Cap and crown repair: Cracked caps and crowns are a common entry point. We reset or replace the cap and repair the crown so water sheds off the chimney instead of running down the chase.
- Hose test and documentation: We run a controlled water test on the finished repair and check the attic again. You get before and after photos from the roof so you can see exactly what was fixed.
- Interior damage assessment: If the leak has stained ceilings or soaked insulation, we document it and can handle the ceiling leak repair and water stain removal so the interior is finished too.

What Chimney Leak Repair in San Marino, Texas actually involves
A chimney leak gets worse with every storm, and guessing at the source costs more than fixing it. We confirm the entry point, rebuild the flashing, and test the repair before we leave.
Chimney Leak Repair in San Marino, Texas is the trade of stopping water that enters a home through the chimney assembly. That means the flashing where the chimney meets the roof plane, the counter-flashing set into the masonry, the cap, the crown, and the mortar joints above the roofline. Most chimney leaks we open up are flashing failures, not the flue itself. Water runs down the brick, hits a lifted step flashing edge, and shows up eight feet away on your ceiling.
San Marino sits in a hail and wind corridor, and the storms that roll through each spring and fall work flashing loose and crack pipe boots and caps. After a hail event, we see chimney flashing leaks on roofs that were watertight the season before. If you have been searching chimney leak fixing near me San Marino Texas and watching a brown ring spread across your ceiling, the source is almost always above the roofline, not in the attic.
- What it is
- Sealing the chimney transition where water enters the roof.
- When it helps
- Ceiling stains, attic moisture, or water in the chase.
- What you get
- A tested repair and photos of the work.

How chimney leak repair runs in San Marino
San Marino sits in the hail and wind belt that runs through this part of Texas, and that shapes almost every chimney leak we see. Spring and fall storms lift step flashing and crack caps, then the summer heat bakes the sealant and the next rain finds the gap.
Monte Vista
Older masonry chimneys with worn step flashing and open mortar joints above the roofline are the most common leak source here.
Beacon Hill
Historic homes with original brick chases often need tuckpointing along with flashing repair to stop water running down the inside.
Stone Oak
Newer roofs tend to leak at factory flashing and pipe boots near the chimney rather than the masonry itself.

PhotoMonte Vista flashing rebuild
Before: A homeowner had a spreading ceiling stain after every rain. Two prior companies had sealed the roof field with no result. The attic showed wet sheathing right beside the chimney chase.
After: We rebuilt the step and counter-flashing, replaced the wet underlayment section, and hose tested twice. The attic stayed dry through the next storm and the ceiling was repaired and repainted.
Beacon Hill cap and crown repair
Before: Water was running down the inside of the chimney and rusting the damper. The cap was cracked and the crown had a visible split that let water pool at the top of the chase.
After: We replaced the cap, repaired the crown, tuckpointed the open joints above the roofline, and sealed the masonry. The chase dried out and the damper stopped rusting.
Stone Oak hail damage flashing
Before: A hail storm dented the chimney flashing and lifted the counter-flashing out of the masonry. The leak showed up three weeks later as a damp patch on the attic decking.
After: We replaced the dented flashing, reset the counter-flashing, replaced two cracked pipe boots nearby, and tested the whole transition. The attic decking dried and stayed dry.
Chimney leak problems we solve in San Marino
Chimney leaks show up in a few predictable ways. Here is what we see most often and how we stop it.
Ceiling water stains that keep coming back
Paint over a stain and it returns with the next rain.
Attic water intrusion around the chimney chase
Wet insulation loses its R-value, roof sheathing softens, and framing can rot over a season. Attic moisture also drives up cooling costs in a Texas summer.
Chimney flashing leaks after hail or wind
Hail dents and lifts flashing, and wind pulls it loose.
Water running down the inside of the chimney
A cracked cap or open mortar joint lets water straight into the chase.
Why homeowners call us for chimney leaks

What San Marino customers say
We had a brown stain spreading across the ceiling every time it rained and two other companies told us it was the roof field. These guys went up, ran a hose on the chimney, and had a tech in the attic watching. Step flashing was shot. They rebuilt it and retested. No leak since, and they showed me photos of the whole thing.
Our chimney cap was cracked and water was running down the inside of the chase. They replaced the cap, resealed the crown, and checked the mortar joints while they were up there. Took about three hours. The price they quoted on the phone was the price I paid, which I appreciated.
We manage several rentals and the chimney leaks were eating our maintenance budget. This crew handled flashing repairs on three properties in one week and documented each one with photos. The attic insulation stayed dry through the next storm, which is the only test that matters.

2109395773If the leak has damaged sheathing or drywall, interior repair adds to that. We give you a written number before we start, so the price you hear is the price you pay.
Yes. We cover San Marino and the surrounding San Antonio neighborhoods, and most chimney leak calls get a same-day or next-day visit. We carry flashing stock, butyl tape and sealant on the truck, so a standard flashing rebuild is usually finished in one trip. If your leak turns out to be a pipe boot or skylight flashing, we handle that in the same visit.
A typical chimney flashing repair takes two to four hours from setup to final hose test. Larger jobs, like rebuilding a crown, resetting a heavy cap or replacing cracked clay tile around the chase, can run a full day. We tell you the expected window when we schedule, and we do not leave until the repair passes a water test.
The three most common causes we find are failed step flashing, a cracked or missing chimney cap, and open mortar joints above the roofline. Hail and wind push flashing loose, and freeze-thaw cycles open the masonry. Water then runs down the chase and shows up on your ceiling, often far from the chimney itself.
