Service overview
Chimney Leak Repair Campbell CA Done Right
Chimney leak repair Campbell CA is the trade of stopping water that enters a home at the chimney, flue, or the flashing where the chimney meets the roof. Water rarely comes through the brick itself. It slips past rusted step flashing, cracked crown mortar, a failed rain cap, or a gap in the counter-flashing, then travels along framing until it drips somewhere far from the actual hole. We open the roof around the chimney, trace the path, and seal it at the source.
Campbell homes take a specific beating. Winter storms push wind-driven rain sideways into chimney chase walls, and summer UV bakes the sealant and crown until it cracks. Older ranch homes near Los Gatos Creek often still have original 1970s flashing that has rusted through. If you have been searching chimney leak repair near me Campbell and getting vague answers, we give you a real diagnosis, photos, and a written scope before we touch a shingle.

Practical benefits
Why Fix a Chimney Leak Now
A chimney leak never gets smaller. It rots the sheathing, stains drywall, and can short a furnace flue. Here is what you get when we handle the repair.
Stop Damage Early
A slow chimney leak can rot roof sheathing and ceiling joists within one rainy season. We catch it with a moisture meter and infrared camera before the framing softens, which keeps a $400 flashing repair from turning into a $4,000 structural job.
Dry Ceilings Again
Most customers call us after they see a brown ring on the ceiling. Once we complete the chimney leak fix Campbell work, the drip stops and the stain stops spreading. We mark the drywall so you know exactly where to prime and paint after it dries.
Code-Correct Flashing
Chimney flashing has to be layered correctly, or it leaks again in two years. We install new step flashing, counter-flashing, and butyl tape to California code, using GAF and CertainTeed materials that hold up to Santa Clara County heat and rain.
Protect the Flue
Water running down a flue liner rusts metal chimneys and spalls masonry. We reseal the crown, reset the rain cap, and check the flue from the roofline so your fireplace stays safe to use through the holidays and into next winter.
How service works
Our Chimney Leak Repair Process
Five steps, no guesswork. You get photos at every stage and a clear answer on what failed and why.
Phone Triage
You call or book online and describe where the water shows up. We ask about ceiling stains, attic drips, and whether the leak appears only during wind-driven rain. That five-minute conversation usually narrows the cause to flashing, crown, or cap before we ever climb the ladder.
Tools and methods
Tools and Methods We Use
Moisture Meter
Reads the water content in drywall, sheathing, and framing so we can confirm how far the leak has traveled and whether the wood is still sound enough to repair rather than replace.
Infrared Camera
Shows temperature differences behind walls and ceilings, which reveals hidden moisture paths that are invisible to the eye. It is how we trace a leak from the ceiling stain back to the chimney.
Hose Test Kit
Lets us reproduce the leak on demand by directing water at the flashing, crown, or cap. If the leak shows up during the test, we know exactly which component failed.
Drones for Roof Inspection
Capture high-resolution images of steep or fragile roof sections around the chimney without putting anyone on a dangerous slope. Useful for tile and metal roofs where foot traffic causes damage.
Pry Bar and Caulking Gun
Used to lift shingle courses and flashing without tearing the surrounding roof, and to apply DAP or 3M sealant in a clean, controlled bead at the flashing joints.
Roofing Nailer
Re-nails shingles and flashing at the correct depth and pattern so the repair matches the surrounding roof and holds through wind-driven rain.
Layered Flashing Detail
Step flashing goes under each shingle course, counter-flashing overlaps the step flashing, and sealant sits at the top edge only. This is the California code-correct layering, and it is why our flashing repairs do not leak again in two years.
Crown Rebuild
We chip out cracked crown mortar, form a new sloped crown, and cure it so water sheds away from the flue instead of pooling at the base. A proper crown rebuild adds years to a masonry chimney.
Hose Test Verification
Every repair ends with a controlled water test over the repaired area while we watch the attic with the infrared camera. If a single drop appears, we stay and fix it before we pack up.
Material Matching
We match GAF, Owens Corning, CertainTeed, and Malarkey shingles, plus Henry and Rust-Oleum sealants, to what is already on your roof. The repair blends in and performs the same as the original roof.

Where this service fits
When to Call for Chimney Leak Repair
You see a brown water ring on the ceiling after the first big November storm.
We inspect the chimney flashing and crown the same week, confirm the entry point with a moisture meter, and complete the repair in one visit. If rain is still coming, we tarp first and return when the roof is dry. The drip stops, the stain stops spreading, and you know exactly what failed and what it cost before we started.
Your tenant in a Campbell Village rental reports water in the closet below the chimney.
We treat rental leaks as priority calls, tarp the chimney the same day, and schedule the permanent flashing repair within the week. You get photos and a written scope you can forward to the property owner. The tenant stays dry, the owner gets a documented repair, and you avoid a second emergency call the next time it rains.
You are selling a home near Downtown Campbell and the inspection report flags a chimney leak.
We provide a written diagnosis, photos, and a fixed repair price you can hand to the buyer's agent. Most flashing repairs are completed within a week so escrow is not delayed. The repair is documented, the buyer's concern is resolved, and the sale moves forward without a price renegotiation over the chimney.
Your fireplace smells musty and the damper is stiff to open.
We inspect the crown, rain cap, and flue for water entry, then repour the crown or reset the cap. If the damper is rusted, we tell you and quote the replacement separately. The musty smell clears once the flue dries out, and the fireplace is safe to use again before the holidays.

How Chimney Leak Repair Runs in Campbell
Campbell sits in Santa Clara County with mild, wet winters and hot, dry summers, and that swing is hard on chimneys. Winter storms push wind-driven rain sideways into the chase wall, while summer UV dries out sealant and crown mortar until it cracks. By November, when the first real rain arrives, the failures are already in place. Most of the homes we work on were built between the 1950s and 1980s, and many still have original flashing that has rusted through. If you have been searching for affordable chimney leak repair Campbell, the honest answer is that a $350 to $850 flashing repair usually solves it, and a rebuild is rarely needed. We work across the 95008, 95009, and 95011 ZIP codes and schedule around the rain, tarping first when a storm is active and returning for the permanent repair when the roof is dry.
Downtown Campbell
Older homes close to the downtown core often have original masonry chimneys with cracked crowns. We see crown rebuilds here more than anywhere else in the city.
Westmont
Two-story homes in Westmont have tall chimney chases that catch wind-driven rain. The leak often shows up on the second-floor ceiling, far from the actual flashing failure.
Campbell Village
A mix of rentals and owner-occupied homes, so we document every repair with photos and a written scope that works for both tenants and property owners.
Los Gatos Creek
Homes near the creek see more moisture and moss on the roof, which hides flashing rust. We check the chimney base carefully on every inspection here.
Pruneyard
A mix of residential and commercial roofs, including flat and low-slope sections where chimney and vent boots fail at the membrane collar.
Wind-driven winter rain from the southwest
Pushes water sideways into the chimney chase wall, which is why so many Campbell leaks only appear during storms and not during a simple hose test from above.
Summer UV and heat above 95 degrees
Dries out sealant and crown mortar until it cracks, which is why fall is the busiest season for chimney leak inspections across Santa Clara County.
Original 1970s flashing on ranch homes
Rusted step flashing and backed-out nails are the most common single cause of chimney leaks we find in older Campbell neighborhoods.
Clay tile and metal roofs on newer builds
Tile hides leaks until the underlayment fails, and metal expands and contracts, so both need chimney flashing checked with a drone or careful foot placement.
Problems we solve
Chimney Leak Problems We Solve
These are the chimney leak calls we get most often in Campbell. Each one has a real cause and a real fix, and none of them require guessing.
Ceiling stain that grows after every storm
We trace the stain back to the chimney with a moisture meter and infrared camera, then repair the failed flashing or crown at the source. Most ceiling stains stop growing after one repair visit, and we mark the drywall so you know where to paint. The drywall keeps absorbing water, the stain spreads, and the framing above it starts to rot. Left alone through a winter, a small flashing leak can soften ceiling joists and force a drywall replacement.
Water dripping inside the firebox
We inspect the crown, rain cap, and flue from the roofline, then repour the crown or reset the cap. If the flue liner is damaged, we tell you and quote the liner separately so you can decide before the next burn season. Water in the firebox rusts the damper, spalls the firebrick, and makes the fireplace unsafe to use. It also signals that the crown or rain cap has failed, which means the flue is getting wet every storm.
Leak that only appears during wind-driven rain
We use a hose test kit aimed at the chimney from the windward side, combined with an infrared camera in the attic, to reproduce the leak on demand. Once we see the entry point, we repair the flashing and seal the chase wall. Sideways rain pushes water into the chimney chase wall, where it travels along framing and shows up far from the chimney. These leaks are the hardest to find and the most likely to be misdiagnosed as a roof or window problem.
Rusted flashing on an older Campbell ranch home
We remove the old flashing, replace any soft sheathing, and install new step flashing, counter-flashing, and underlayment. The repair is layered to California code so it sheds water the way it was supposed to from the start. Original 1970s flashing has usually rusted through by now, and the nail heads have backed out. Water gets behind the metal and soaks the sheathing, which is why so many older Campbell homes have soft spots near the chimney.
A practical standard for every visit.

Where we work
One local team. A lot of ground covered.
Most chimney leak repairs in Campbell run $350 to $850, and crown rebuilds run $600 to $1,200. The price depends on whether the leak is at the flashing, the crown, the rain cap, or the flue. A simple step-flashing reseal sits at the low end; a full flashing replacement with new underlayment sits at the high end. We give you a fixed written price after the inspection, so you know the number before we start.
Yes. Most chimney leaks have nothing to do with the brick itself. Roughly 8 out of 10 leaks we find are flashing, crown, or cap failures, and all three can be repaired without tearing down the chimney. We replace the step flashing, counter-flashing, and sealant, or pour a new crown. A full rebuild is only needed when the masonry is spalling or the flue liner has failed.
The three most common causes in Campbell are rusted step flashing, cracked crown mortar, and a missing or loose rain cap. Wind-driven winter rain pushes sideways into the chase, and summer UV dries out the sealant until it opens. Older ranch homes near Los Gatos Creek often still have original 1970s flashing. We check all three on every inspection and show you photos of what failed.
For active leaks, we usually reach Campbell Village and the surrounding neighborhoods within a few hours on emergency calls, and we schedule standard inspections within one to two business days. If rain is still coming in, we tarp the chimney first and return for the permanent repair once the roof is dry. Call us and we will give you a real arrival window.
