We serve homeowners across Los Angeles County with same-day estimates and honest repair scopes.
Chimney Leak Repair Whittier CA is a water-intrusion service that reseals the points where your chimney meets the roof and sky. Water gets in through failed step flashing, cracked crown mortar, open brick joints, a rusted chase cover or a missing rain cap. We test with a hose, confirm the path with a moisture meter and infrared thermal camera, then repair the flashing, crown and counter-flashing so the chase sheds water the way it was built to.
Most Whittier chimneys sit on homes built between the 1920s and 1970s, and the original mortar has had decades of sun and Santa Ana wind. A single winter storm can push water past a hairline crack and into your attic insulation. If you have been searching chimney repair near me after a ceiling stain appeared, we can usually get eyes on it the same day and stop the leak before the next rain.
Every chimney leak repair starts with a full inspection and a water test, then moves to the actual repair. The list below is what is covered in a standard scope. If we find cracked flue tiles or structural masonry damage, we tell you and bring in a chimney specialist rather than guessing at it.
Roof-level inspection of the flashing, crown, chase cover and brick joints, plus an attic check with a moisture meter and infrared thermal camera. You get photos of every defect we find and a plain-language explanation of which one is letting water in.
We run a hose at the chimney base while watching from inside. This confirms the entry point before we quote. It takes about 20 minutes and prevents the most expensive mistake in leak repair: fixing the wrong thing.
New step and counter-flashing bent on site with a flashing bender, set into the mortar joint and sealed with Henry or Tremco roof cement. This is the repair that stops most chimney leaks in Whittier.
Cracked crown mortar is rebuilt with a flexible sealant that moves with the chimney, and open joints are repointed. This keeps water from soaking into the brick and spalling the faces during freeze-thaw cycles.
Rusted or loose chase covers are reseated or replaced, and missing rain caps are installed. Both keep rain and debris out of the flue and protect the damper from rust.
We re-run the water test, confirm the repair is dry, photograph the finished work and hand you a written workmanship warranty. You also get a short maintenance note on what to check each spring.
We set a roof ladder, walk the plane and inspect the chimney from the ridge down. Inside, we check the attic decking and insulation with a moisture meter. This step takes 30 to 45 minutes and tells us whether the leak is flashing, crown, masonry or a roof-plane issue.
We run a controlled hose test at the chimney base while a second technician watches from inside. An infrared thermal camera confirms the wet path. We do not quote a repair until we have seen water move, so you are not paying to guess.
Failed step flashing comes out and new metal is bent on site with a flashing bender. We reset counter-flashing into the mortar joint, seal with Henry or Tremco roof cement, and rebuild cracked crown mortar with a flexible sealant that moves with the chimney.
Open mortar joints get repointed and the chase cover or rain cap is reseated or replaced. If the flue tile is cracked, we note it for a chimney specialist. Most jobs are watertight in two to four hours.
We re-run the hose test, confirm zero moisture movement, and photograph the finished work for your records. Debris goes in the truck, not your gutters. You get a written warranty on the repair and a note on what to check each spring.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Reads water content in attic decking, insulation and drywall so we know how far the leak has traveled before we quote the repair.
Shows temperature differences behind finished surfaces, which reveals the wet path from the chimney chase to the ceiling stain.
Bends new step and counter-flashing on site for an exact fit against your chimney and roof pitch, instead of forcing a stock piece.
Delivers a controlled flow at the chimney base while a second technician watches inside, confirming the entry point before repair.
Gets technicians safely onto tile, shingle and low-slope roofs. We carry OSHA-rated harnesses and anchors on every job.
Used to remove failed sealant and set new Henry, Tremco or Sika products cleanly into the joint so the seal lasts.
Captures high-resolution images of steep or fragile tile roofs where walking the plane risks breaking material.
A homeowner had a spreading brown ring on the ceiling beside the chimney after two winters of patching. The counter-flashing had pulled out of the mortar joint and water was running behind it into the attic decking.
We fabricated new counter-flashing on site, set it into a cut mortar joint and sealed it with Tremco. The hose test ran clean, and the moisture meter reading in the attic dropped to dry within four days.
A tile-roof home had a musty firebox and a rusted damper every fall. The crown had cracked across two sides and rain was soaking into the flue. The homeowner assumed the tile roof was the problem.
We rebuilt the crown with flexible sealant, reseated the chase cover and replaced the rain cap. A hose test confirmed the flue stayed dry, and the damper was replaced separately so the fireplace sealed properly.
During a winter storm, water was dripping into a bedroom ceiling near the chimney. The step flashing had lifted on one side and the homeowner needed the flow stopped that night.
We tarped and diverted the entry point the same evening, then returned in dry weather to install new step flashing and reseal the joints. The repair was water-tested and warrantied, with no new staining after the next storm.
Chimney leaks show up in different ways depending on the roof type and the age of the flashing. These are the four patterns we see most often on Whittier homes, and what each one costs you if it is left alone.
Ask a pro →We trace the stain back with a moisture meter and infrared thermal camera, confirm the entry point with a hose test, then repair the flashing or crown that is actually failing. Most customers see no new staining after the next rain.
We reseal the crown, chase cover and counter-flashing so rain stays out of the flue. If the damper is already rusted, we note it for replacement and keep the repair focused on stopping the water first.
We remove the failed metal, fabricate new step flashing on site with a flashing bender, and set it into the mortar joint with Henry or Tremco sealant. The repair is water-tested before we leave.
We rebuild the crown with flexible sealant and repoint open joints. This is a fraction of rebuild cost and buys years of service. We photograph the brick condition so you know what to monitor.
$350 - $1,200 depending on scope
Typical 2026 pricing for chimney leak repair in Whittier runs $350 to $1,200, with most flashing and crown reseals landing near $550. The number depends on roof pitch, roof material, how much flashing needs replacement, and whether the crown or masonry needs rebuilding. We give you a flat price after the water test, so you approve the scope before we start. If you are comparing chimney repair near me quotes, ask whether the price includes a water test and a written warranty. Ours does.
A $550 flashing and crown repair protects framing, insulation and masonry that cost thousands to replace. We water-test every job, document it with photos and back the workmanship in writing, so the price you approve is the price you pay.
Steep or tall roofs need more fall protection and take longer to access safely. A two-story home with a steep pitch adds labor compared with a single-story low-slope roof.
Composite shingle is the fastest to work around. Clay and Spanish tile must be lifted and reset carefully, which adds time and risk, and tile underlayment repair is priced separately if it is also failing.
A simple counter-flashing reseal is the low end. Full step flashing replacement with new metal bent on site sits in the middle. If the chase cover is rusted through, replacement adds to the total.
A hairline crown crack is a quick seal. A crown cracked across multiple sides needs a rebuild. Open mortar joints add repointing time, and spalled brick may require a chimney specialist.
“We had a brown ring spreading on the ceiling right next to the chimney. The technician hose-tested it, found the counter-flashing had pulled loose, and had new metal bent and sealed the same afternoon. Two storms later, no new stain. He also showed me photos of the crown so I know what to watch.”
Marisol R.Homeowner, Uptown Whittier
✓ Verified“Our tile roof made the leak hard to pin down. They lifted tiles, checked the underlayment and confirmed the chimney flashing was the entry point, not the tile. Repointed a few mortar joints while they were up there. Flat price, no add-ons, and they cleaned the gutters of debris before leaving.”
Dennis K.Homeowner, Friendly Hills
✓ Verified“Called after a storm pushed water into our firebox. They tarped it that evening and came back in dry weather to rebuild the crown and reseal the chase cover. The damper stopped rusting and our first fire of the season burned clean. Fair price and they answered the phone every time I called.”
Alicia T.Homeowner, Hadley-Greenleaf
✓ VerifiedMost chimney leak repairs in Whittier run $350 to $1,200 in 2026, with a typical flashing and crown reseal landing near $550. Simple counter-flashing reseals start around $350. Full chase cover replacement, masonry repointing or tile underlayment repair pushes the number higher. We give you a flat price after the water test, so you are not guessing.
The three most common causes we find in Whittier are failed step flashing, a cracked crown and open mortar joints. UV exposure and Santa Ana winds dry out sealant faster here than in coastal neighborhoods. After heavy rain, water also backs up behind debris on the chase cover. A hose test and moisture meter reading tell us which one you have.
Yes, when the chimney is the actual entry point. Roughly one in four ceiling leaks we inspect in Whittier traces back to the chimney flashing rather than the field shingles. If the water is entering at a valley, pipe boot or skylight instead, we tell you that and quote the correct repair rather than selling chimney work you do not need.

Flashing RepairChimney leaks and flashing failures are the same job most of the time. We fabricate new step and counter-flashing on site, seal it into the mortar joint and water-test it. If your leak is at a wall or sidewall rather than the chimney, this is the repair that stops it.Explore →
Skylight Leak RepairSkylights and chimneys share the same weakness: a penetration through the roof plane. When a Whittier homeowner has two ceiling stains, we test both. We reseal the skylight curb and replace failed seal kits so the chimney repair is not undone by a second leak nearby.Explore →
Valley Leak RepairWater from a chimney can run down into a roof valley and look like a valley leak. We clear debris, check the valley metal and underlayment, and confirm whether the chimney or the valley is the true source before quoting. Misdiagnosis is how homeowners pay twice.Explore →
Vent and Pipe Boot Leak RepairPlumbing vents near the chimney chase often fail at the same age as the flashing. We replace cracked pipe boots and reseal vent collars during the same visit, so one trip up the roof fixes every penetration showing wear.Explore →
Flat Roof RepairSome Whittier additions and garages have flat or low-slope sections tied into the chimney. Ponding water there finds the same seams. We repair roof coating, seams and drains so the chimney base is not sitting in standing water after every storm.Explore →
Tile Roof RepairWhittier has a lot of clay and Spanish tile, and tile underlayment failure is a common chimney-leak lookalike. We lift and reset tiles, replace torn underlayment and reinstall the chimney flashing correctly so the tile and the metal work together.Explore →
Shingle RepairOn composite shingle roofs, chimney leaks often start with lifted or missing shingles at the flashing edge. We replace damaged shingles with matching GAF or CertainTeed product and re-nail the flashing so the repair blends and holds.Explore →

We document wind and impact damage, tarp active entries, and handle the permanent repair once the weather clears.
