The 5 Ways Water Gets In

Wherever It's Coming From — We Close It

Every chimney leak enters through one of five points. We check all five on every call, and we repair every one of them.

Entry Point 01

Cracked Crown

The concrete top splits in Texas heat - we repair or re-pour it to shed water again

Entry Point 02

Missing or Failed Cap

An open flue drinks every storm - caps, chase covers and custom shrouds installed

Entry Point 03

Lifted Flashing

The roof-to-chimney seam is the classic culprit - reset, resealed and watertight

Entry Point 04

Porous Brick & Mortar

Soaked masonry repointed with matched mortar, then sealed with breathable waterproofing

Entry Point 05

Flue Condensation

Moisture forming inside the flue itself - diagnosed and corrected at the source

Not sure which one is yours? That's our job, not yours - the diagnosis is part of the free estimate.

Chimney Leak Repair · San Antonio

The stain on your ceiling is never where the leak is.

Water is patient. It slips in through a hairline crack in the crown, a lifted piece of flashing, or brick that's been drinking rain for years - then travels down inside the structure until it finally shows up as a stain, a drip, or that musty smell after a storm.

That's why "sealing where the stain is" almost never works. We trace the water back to where it actually enters - and fix that. Once, properly, in writing.

We Trace It to the Source

Crown, cap, flashing, masonry, condensation - we check every entry point, not just the obvious one.

You See What We See

Photos of the actual entry point and a written estimate - before any work begins. Free, even on-site.

Fixed Once. Backed 3 Years.

Certified & insured technicians repair the real cause - with a 3-year workmanship warranty in writing.

Is Water Getting In?

Six Signs Your Chimney Is Leaking

Most of these show up far from the actual entry point - which is exactly why leaks get misdiagnosed. Spot any of them? The estimate is free.

Stains on the Ceiling or Wall

Brown or yellow rings near the chimney - often a room away from where the water actually enters. The stain marks the exit, not the entry.

Water in the Firebox

Puddles, damp ash, or drip sounds inside the fireplace after rain. This is the most direct sign - water is running straight down the flue.

Musty Smell After a Storm

That damp, earthy odor from the fireplace means moisture is sitting inside the chimney - and it never dries out on its own down here.

White Chalky Residue on Brick

Efflorescence - minerals left behind as water passes through the masonry. If you see white, the brick is soaked inside.

Rusted Damper or Firebox

Metal parts inside a chimney should never rust. If the damper is stiff, flaking, or orange - water has been visiting for a while.

Peeling Paint or Bubbling Drywall

Paint or wallpaper lifting near the chimney chase means moisture is inside the wall - the stage right before visible mold.

Water damage compounds. What's a flashing or crown fix today becomes drywall, framing, and mold remediation next season.

How We Stop a Leak For Good

Not "spray some sealant and hope." A real diagnosis, a real repair, and a warranty that means it - here's the process.

1

Tell Us What You're Seeing

A stain, a drip, a smell after rain - call (726) 259-1693 or send the form with photos if you have them. Active leaks get priority scheduling, same-day when our schedule allows.

2

We Trace the Water to Its Source

Crown, cap, flashing, masonry, condensation - we check every entry point until we find where water actually gets in. You get photos of the entry point and a written estimate, free - even when the visit is on-site.

3

We Fix the Cause — Not the Symptom

Whatever the source needs: crown rebuild, new cap or chase cover, flashing reset, matched-mortar masonry, or breathable waterproofing. Done by certified & insured technicians who protect your roof and property while they work.

Walkthrough, Photos & 3-Year Warranty

We show you exactly what was done, with before-and-after photos - documentation that's also ready for an insurance claim if you're filing one. Every repair is backed by a 3-year workmanship warranty, in writing.

Why Leak Calls Come to Us

Anyone Can Seal a Crack. We End Leaks.

The difference between a leak that comes back next storm - and one that never does.

Source-First Diagnosis

We don't caulk the stain and drive away. We trace the water to its actual entry point - because a leak fixed in the wrong place isn't fixed.

Water doesn't wait, so neither do we. Active leaks get priority scheduling, same-day when our schedule allows, typically within 24 hours.

Insurance-Ready Documentation

Photos of the entry point, the damage, and the repair - plus a detailed written quote ready to hand your insurance company.

3-Year Warranty, In Writing

All work by certified & insured technicians, backed for three full years. If our repair ever lets water through, we come back and make it right.

Leak Stories, Real Homes

They Had a Leak. Now They Don't.

 Real feedback from San Antonio homeowners

"I can't thank these guys enough. We noticed water staining on our ceiling after a heavy storm and panicked thinking about the repair costs. They came out the exact same day, diagnosed the chimney leak immediately, and had it completely fixed within 24 hours. If we had waited, we'd have been looking at tens of thousands in ceiling and flooring damage. Truly saved our home and our wallets."

Leak Questions

Chimney Leak FAQ

The questions every leak caller asks - answered straight, the way we'd answer on the phone.

It genuinely depends on the source. A flashing reset costs very differently than a crown rebuild - and we won't know which one you need until we trace the leak. That's why the estimate is free, even on-site: you get a real number for your leak, not a guess. If you'd like a full documented inspection with photos, that's $79.
Yes - that pattern is actually a clue, not a problem. Leaks that appear only in hard or wind-driven rain usually point to specific entry points like flashing or crown cracks. We check every entry point systematically, so we don't need to catch it mid-storm to find it.
Sealant over an unfixed source is a bandage - and the wrong sealant can actually trap moisture inside the brick, making the damage worse. Waterproofing has its place: as the final protective layer after the actual entry point is repaired. That's the order we always work in.
Active leaks get priority scheduling - same-day when our schedule allows, and typically within 24 hours. Water damage compounds by the day, so if it's dripping right now, call rather than fill the form: (726) 259-1693.
Often, when the leak stems from a sudden event like storm damage - though gradual wear is usually excluded. Coverage is always between you and your insurer, but here's what we do: provide photos of the entry point, the damage, and a detailed written quote so you walk into the claim with solid paperwork.
Five usual suspects: a cracked crown (the concrete top), a missing or damaged cap, failed flashing where the chimney meets the roof, porous brick and mortar joints that soak up rain, and condensation inside the flue. On every leak call, we check all five - because assuming is how leaks get "fixed" twice.
Almost never - if it's caught early. Most leaks are resolved with a targeted repair: a crown fix, a new cap, flashing work, or repointing. Rebuilds happen when water has been eating the masonry for years unnoticed. Which is the whole argument for a free estimate now instead of later.
Yes, every repair we complete is backed by a 3-year workmanship warranty, in writing. If water ever gets through something we fixed, we come back and cover the labor. Storm damage and acts of nature aren't workmanship, but even then you get a major discount on labor.
