Chimney Repair in Glendora
Licensed, CSIA-certified technicians providing expert chimney repair to homeowners across Glendora and the eastern San Gabriel Valley foothills.
A typical job, from call to finish
Imagine a homeowner in Glendora who hears a faint whistling sound near the fireplace on a windy evening, even with the damper closed and no fire burning, and notices the room nearby runs colder than the rest of the house. Together those two signs usually point to a damper that isn't seating and sealing the way it's supposed to. A visit would typically start with the technician testing how the damper opens, closes, and seats against the flue opening, checking for warping, rust, or a worn seal. What the service addresses is restoring that seal, whether through adjustment or a full replacement, so the flue closes off completely when the fireplace isn't in use. A damper that seals properly is what stops that draft and that whistle at the source.

What homeowners typically pay
Chimney repair is quoted after the inspection, never before it. A Level I inspection is $49 for new customers who book online, a visual assessment with no camera and no video scan, and the written estimate that follows documents every issue with photos. Which repairs to proceed with is the homeowner's decision. A standard chimney sweep starts at $199, with the inspection fee waived when you add one to the same visit.

Scaffolding SetupChase Cover & Shroud Repair, Two-Story Scaffolding
Southern California
A standard 30-foot ladder wasn't enough to safely reach this two-story chimney, so Eco Grizzly set up proper scaffolding to get the job done right. The previous contractor had left a poorly installed chase cover and shroud that was loose and on the verge of falling, a serious hazard to the roof and anyone below. Our team removed the failed installation, corrected the mounting, applied sealant at all seams and fastener points, and provided the homeowner with permanent options to prevent future issues. Another job done right, and another incredibly happy client.
BeforeSmoke Chamber Breastplate Repair
Southern California
The breastplate (the sloped front wall of the smoke chamber above the firebox opening) had developed significant cracks and spalling that allowed carbon and gases to escape into the surrounding masonry. Our crew cleaned out all loose material, rebuilt the damaged area with refractory-grade mortar, and smoke-tested the repair to confirm a complete seal. The homeowner can now operate the fireplace safely without risk of CO migration.
BeforeChimney Cap & Top-Sealing Damper Installation
Southern California
The existing cap was rusted through and no longer keeping water out of the flue. We removed the failed cap, cleaned up the crown edges, and installed a heavy-gauge stainless steel chimney cap paired with a top-sealing damper. The top-seal closes the flue completely when the fireplace is not in use, eliminating cold downdrafts, preventing animal entry, and cutting heating and cooling energy loss. A second angle shot confirms the tight, level fit.
BeforeChimney Cap & Top-Sealing Damper Replacement
Southern California
This chimney had been operating without a functional cap, leaving the flue open to rain, debris, and animals. Our technicians measured the flue tile, fitted a new multi-flue stainless cap, and paired it with a top-sealing damper. The assembly locks down tight between uses, dramatically reducing heat loss and preventing moisture damage inside the flue liner.
BeforeChimney Cap Installation
Southern California
Without a chimney cap, the flue is exposed to rainwater that accelerates liner deterioration and masonry damage. We removed the old broken cap, cleaned the crown surface, and secured a correctly-sized stainless steel spark-arresting cap. The mesh sides prevent bird and animal entry while still allowing proper smoke exit, a simple upgrade with major long-term protection benefits.
BeforeChimney Cap Replacement
Southern California
The old cap was undersized and heavily corroded, allowing wind-driven rain to enter the flue on the sides. Our crew sourced a correctly-sized stainless steel cap, cleaned the crown, and installed the new cap with a secure fit. The homeowner now has reliable rain and animal protection without the rust staining that was streaking down the masonry.
BeforeChimney Crown Repair
Southern California
The concrete crown had developed deep radial cracks, a common result of Southern California's temperature swings, allowing rainwater to penetrate the masonry below. Our crew chiseled out all loose material, applied a bonding primer, and finished with two coats of elastomeric crown coat that flexes with seasonal movement. The finished crown sheds water cleanly away from the flue tile and masonry, halting further damage.
BeforeChimney Crown Reseal & Waterproofing
Southern California
Years of UV exposure and rain cycles had left this crown pitted and porous. Water was wicking through and freezing inside the masonry during cold nights, accelerating spalling in the brick below. We ground down high spots, filled voids with hydraulic cement, and applied a full elastomeric waterproof crown coat. The gray finished surface is smooth, sloped to drain, and flexible enough to move with the structure without cracking.
BeforeFull Chimney Crown Rebuild
Southern California
The original crown was beyond patching, it had separated from the flue tile and broken into large sections. Our masonry crew demolished the failed crown, built new formwork around the flue tile, poured a properly-sloped Portland cement crown, and finished with an elastomeric waterproof coat once cured. The rebuilt crown projects slightly past the masonry on all sides to throw water clear of the chimney stack.
BeforeDamper Clamp Installation
Southern California
The existing throat damper plate had corroded and no longer closed fully, allowing constant cold downdrafts and energy loss. Rather than an expensive full damper replacement at this time, we installed a heavy-duty damper clamp that holds the damper plate securely shut. The clamp features a chain release so the homeowner can open it easily before lighting a fire. A cost-effective solution that immediately solved the draft and energy issue.
Original CoverRooftop Chimney Chase Cover Replacement
Southern California
The original chase cover had begun pulling away from the stucco chase, leaving an open gap along the top edge under a set of weathered galvanized caps. Our crew lifted the old cover off to expose the wood chase framing and the three flue pipes running up inside it. We fitted new white sheet metal to the chase with a raised standing edge and an overhang that drops water clear of the stucco below, then sealed the perimeter and installed new flue caps with mesh screens. The finished chimney sits clean and bright against the tile roof and is sealed against rain, debris, and animals.
