Say what you have seen or heard at your Altadena house, and we will call to set a time.
Around Altadena the roofs carry older craftsman and ranch houses, hillside cabins, and homes being rebuilt after the 2025 eaton fire, and each kind gives birds, squirrels and weather a different way in. Crosby Chimney Care handles chimney masonry repair here with that in mind, one roof at a time.

The setting
the foothill streets below Eaton Canyon and Echo Mountain
Altadena runs right up to the San Gabriel foothills, and raccoons, squirrels, birds and bats come down looking for a dry, quiet flue. The January 2025 Eaton Fire destroyed or damaged many homes here, and chimneys on houses that stayed standing can still hold ash and fallen debris inside.
Streets near you
The list below is a sample, not a boundary. If your block is in or next to Altadena, a call settles it in a minute.
Expect gaps used by animals or wasps filled first, joints ground out and repointed, and spalled and cracked bricks replaced. Afterward you receive photos and a short note on what we found, what we did and what can wait, whether the job stayed simple or turned up a repair.
Santa Ana season sends wind down the canyons hard enough to bend a loose cap or lift it clean off. On these streets the spark arrestor mesh earns its place twice: it holds embers in and keeps animals out. Late summer, before the first fire, is the busiest window. Late spring, once nesting season ends, is the best time to get a cap on before next year's birds arrive.
Our crews cover Altadena plus Kinneloa Mesa, Pasadena, and Sierra Madre. Postal codes on the route: 91001 and 91003. On a border street? Ask when you call and we will check the map with you.
Many visits turn up a second problem, like a rusted cap during a sweep or a wet crown during a nest removal. These pages cover those jobs.
Brushwork, nest pulling and a close look at the cap, so a flue that gets swept also gets checked for whatever moved in.
Read this oneFlashlight, camera and ladder: a top to bottom look for cracks, rust, open joints and signs that something has been living inside.
Read this oneSplits, gaps and loose tiles that let rain and small animals in, repaired once we know where the trouble really starts.

Read this onePrices do not change from one town to the next. What changes is the trees, the roofs and the animals, and each page says how.
the oak-shaded streets between the Arroyo Seco and Chapman Woods
Hastings Ranch, our home base, sits in the northeast corner of Pasadena, and this page covers it along with the older blocks toward the Arroyo Seco. Oaks and sycamores shed onto crowns all autumn, and an older bungalow flue left open without a cap is an easy door for a squirrel, a bird or a raccoon. A Pasadena call often starts with scratching behind the mantel or twigs on the grate.
Open town pagethe large-lot residential streets just south of Pasadena
A San Marino house may carry two or three chimneys, and the flue over the room nobody uses is the one birds and squirrels pick. Big trees on wide lots drop leaves onto every crown and into the gap behind each stack.
Open town pagethe tree-lined grid of older houses below San Marino
Alhambra keeps many older bungalows with short brick chimneys close to the roof, so roof rats and pigeons reach the top with little effort. A chimney that has gone several winters without a fire is the kind animals move into.
Open town pagethe wooded hillsides between the Arroyo Seco and the Angeles Crest Highway
La Canada Flintridge sits against the Angeles National Forest, with oaks overhead and brush on the slopes. Raccoons, squirrels and birds pass through the yards, and an open flue on a quiet house makes a ready den.
Open town pagethe Crescenta Valley streets around Honolulu Avenue
Montrose lies in the Crescenta Valley below the San Gabriels, with the Verdugos across the way, so wildlife drifts in from two directions. Squirrels and birds take over uncapped flues, and street trees stuff crowns with leaves each fall.
Open town pageIt will. Altadena is a regular stop for Crosby Chimney Care, and the same trip often takes in Kinneloa Mesa and Pasadena. Tell us the street when you book and we will give you a window.
Expect gaps used by animals or wasps filled first, joints ground out and repointed, spalled and cracked bricks replaced. The final price depends on what we find at the top of the chimney and inside it, and anything beyond the visit is quoted on paper first.
Usually not. Small openings get bigger: a loose cap, a cracked crown or an empty nest left over winter tends to mean water damage or new tenants by spring. We see both across 91001, 91003.
