Chimney Leak Repair and Service in Ventura County
Alderwood Chimney Services follows chimney leaks from the stain inside to the crown, cap or flashing that let the water in, for homes across Ventura County. Each city page below describes the weather and the house types we work with there, and where their chimneys usually leak.
Where we trace chimney leaks
Choose your city to see where chimneys there tend to let water in, then book a visit.
the Conejo Valley neighborhoods from Newbury Park to Westlake Village
Thousand Oaks
Tile roofs are everywhere in Thousand Oaks, and they make chimney leaks harder to spot because the tiles hide the flashing underneath. Many calls here start with a ceiling stain beside a stucco chase, and the cause is often a flat, rusted chase cover holding water at the top. Brick chimneys on the hillside streets more often leak at the counter flashing.
the city's neighborhoods across the basin and the valleys
Los Angeles
We take Los Angeles calls when a leak needs the same tracing work we do in Ventura County: the stain inside, the attic, then the roof. The city's mix of clay tile, flat roofs and composition shingle means flashing details change from house to house, and parapet walls on some older homes add one more seam where water gets in.
the flat streets and foothill neighborhoods between the Oxnard Plain and the Conejo Grade
Camarillo
Camarillo sits far enough from the ocean for warm afternoons but close enough for morning fog, so chimney metal here sees both moisture and heat. Galvanized caps and chase covers tend to show rust streaks sooner than owners expect. On the single-story ranch homes, the chimney often rises through a low roof slope where leaves and water collect behind it.
the small Santa Clara River Valley town upstream from Santa Paula
Fillmore
Fillmore was hit hard by the 1994 Northridge earthquake, and many chimneys in town were repaired or rebuilt afterward. Where cracks were sealed over rather than fixed, water has had decades to work in through them. We look closely at the crown and the top few courses on any chimney here, because shaking does the most damage there and rain enters there first.
the eastern Ventura County city of planned neighborhoods and open hills north of Thousand Oaks
Moorpark
Most fireplaces in Moorpark's newer neighborhoods are factory-built and set inside stucco chases, so the leaks we find here often start at the chase cover or the termination cap rather than at brick. A flat or rusted chase cover holds water at the top until it finds its way down inside the chase. The ranch homes on larger lots more often have masonry chimneys with crown and flashing issues.
the Ojai Valley, from the village center out to the ranches and canyon roads
Ojai
Ojai chimneys tend to get more use than coastal ones, because winter nights in the valley are noticeably colder. More burning means more creosote, and when rain reaches that creosote through an uncapped flue it turns into a sour-smelling, acidic sludge that attacks mortar joints. Many homes here also run wood stoves, whose roof penetrations need the same attention as a masonry chimney.
the coastal plain neighborhoods from the harbor and beaches inland to the farm fields
Oxnard
Salt air is the main thing working on chimneys in Oxnard, especially in the neighborhoods closest to the harbor and the beaches. It corrodes galvanized caps, rusts flashing fasteners and eats through steel chase covers much faster than it does inland. When we find water in a firebox here, a corroded cap or a rusted-out chase cover is usually part of the story.
the Santa Clara River Valley town below the foothills, among the citrus and avocado groves
Santa Paula
Santa Paula chimneys deal with irrigation as much as rain. Sprinklers and orchard water hitting the base of a chimney can keep brick wet right through the dry months, and we often trace white stains on the lower courses to a misaimed sprinkler head rather than a roof leak. Brick stacks near downtown more often leak at the top, through worn crowns and open joints.
the valley city on the Los Angeles County line, from the tract neighborhoods to the hillside streets
Simi Valley
Simi Valley was close to the epicenter of the 1994 Northridge earthquake, and chimneys across the city were cracked or damaged. Many were rebuilt or replaced, but others were patched, and water has been finding those old cracks ever since. We often trace leaks here to crowns and flue tiles that were never fully repaired after the quake.
the county seat, from the hillside streets above downtown to the flats near the beaches
Ventura
Ventura gives us both kinds of chimney water problem in one city. Near the beach, salt air corrodes caps and flashing. On the hillsides above downtown, wind-driven rain hits exposed chimneys hard, and many brick stacks there were finished with a thin mortar wash instead of a true crown, which cracks and lets water into the core.
