Covina’s older neighborhoods, from the eastside blocks near Barranca Avenue to the tracts south of the 10 Freeway, share a common story: brick chimneys that look solid from the curb but harbor damage from earthquakes most homeowners never knew affected them. We document every inspection with photos you can see and a plain-English verdict. No builder-grade materials, no callbacks, no arguing.

Why Hearthstone Chimney Co. of Los Angeles Is Covina’s Preferred Chimney Repair Company

We’ve worked on chimneys in all three Covina ZIP codes - 91722, 91723, and 91724 - since 1984. That’s long enough to have repaired the same chimney twice: once after the 1987 Whittier Narrows earthquake, and again decades later when the original clay liner finally gave way and needed a Chimney Liner & Rebuild in Covina. Gil Mercer and our technicians understand that Covina homeowners who have lived in their houses for twenty or thirty years want the job done right so they never have to think about it again.

Our reputation here is built on documentation. Every Level-2 camera inspection ends with photos and a written verdict. The 90-Day Done Right Promise is backed in writing with no paperwork and no arguing - if it’s not right, we come back. Most repairs are completed in a single visit by background-checked, uniformed technicians who arrive when we say we’ll arrive.

Calls are answered by a live person, not a voicemail system, not a callback queue. That matters when you smell smoke where it shouldn’t be, or when you’ve just relit your fireplace after months of AQMD No-Burn days and something doesn’t smell right.

Our Chimney Repair Services in Covina

Mortar Repointing

The mortar joints in Covina’s 1950s-1970s brick chimneys have endured forty to seventy years of inland San Gabriel Valley temperature swings - summer days above 90°F, winter nights in the 40s, and months of complete dormancy during AQMD burn restrictions. That cycle pulls mortar apart grain by grain. Repointing removes deteriorated mortar to proper depth and packs fresh, properly mixed mortar that matches the original joint profile. On a 1962 ranch near Citrus Avenue, we repointed a chimney where the original mortar had turned to sand; the homeowner had assumed the whole chimney needed rebuilding. It didn’t.

Spalling Brick Repair

Spalling - bricks flaking and crumbling - accelerates when chimneys alternate between heavy use and long dormancy, which is exactly the pattern AQMD rules create in Covina. Water trapped in porous brick freezes, expands, and pops the face off the brick. We remove spalled units, source matching replacement brick where possible, and address the water source. In Covina’s 91724 ZIP, where many homes sit on slightly higher ground with more wind exposure, we see spalling concentrated on the north and west faces of chimneys.

Chimney Waterproofing

Covina’s winter rainfall is modest but concentrated, and chimneys that sit unused for weeks become water-absorbing sponges rather than heat-drying structures. We apply professional-grade breathable sealers, not the hardware-store coatings that trap moisture inside. On the eastside near Barranca Avenue, we waterproofed a 1958 chimney that had been taking on water through hairline crown cracks for fifteen years until we installed a Chimney Cap & Crown in Covina. The Gelco waterproofing we use allows the brick to breathe while shedding rain.

Flashing Repair

The intersection where chimney meets roof is the most leak-prone point on any Covina home, and on older ranches with original flashing, the galvanized steel has often corroded through or pulled loose from decades of thermal movement. We repair and replace flashing using materials that match the roof system - copper, steel, or specialized membranes - and we seal with compounds rated for the temperature range. A proper flashing repair on a Covina ranch home should outlast the roof itself.

Trusted Brands We Service in Covina

We stock professional-grade materials from HeatShield, Gelco, Olympia Chimney, and Famco - no builder-grade substitutes, no waiting two weeks for parts. When a Covina homeowner needs a liner repair, we pull DuraFlex stainless steel liners from our own inventory. When waterproofing is required, we apply Gelco compounds formulated specifically for masonry chimneys in climates like ours. This means most Covina jobs are completed in a single visit, and the number on the estimate is the number on the invoice.

Common Chimney Repair Problems We See in Covina Homes

• Hidden clay liner cracks from the 1987 Whittier Narrows and 1994 Northridge earthquakes. The epicenter of the 1987 quake sat roughly 12 miles southwest of Covina, and the fault movement ran directly under the eastern San Gabriel Valley. Many chimneys look intact from the roofline, but our camera inspections reveal offset or shattered clay liner sections that allow carbon monoxide into wall cavities. Most homeowners have never been told this damage exists.
• Animal nesting in dormant flues during AQMD No-Burn months. Roof rats and birds treat unused chimneys as permanent housing. When the first winter fire is lit after weeks of dormancy, blocked airflow forces smoke and carbon monoxide into the living space. We remove nests and install proper screening.
• Mortar deterioration accelerated by the use-dormancy cycle. AQMD Rule 445 eliminates many burn days during the season when Covina residents would otherwise use their fireplaces regularly. Chimneys that sit cold for weeks, then fire hard for a single evening, experience thermal shock that spalls brick and opens mortar joints faster than consistent use would.
• Original clay-tile flue liners in 1950s-1970s homes reaching end of service life. These liners were never designed for seventy years of service. In Covina’s unrehabilitated housing stock, we regularly find liners with cracked tiles, missing mortar between tiles, or complete collapse in the offset section.
