Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Glendora, CA
Mantel Chimney Sweep handles chimney repair in Glendora with a focus on what actually fails here: cracked crowns, deteriorated mortar joints, and flue liners damaged by years of heat cycling and wildfire ash exposure. Glendora’s mix of mid-century tract homes on the flats and older custom foothill homes means we see everything from original 1960s brick chimneys to hillside masonry stacks that took direct hits from the Valley Fire’s ash fall. If your chimney needs more than a sweep, call us at (844) 821-5749 for an assessment built around long-term fire safety, not a quick patch.
Why Glendora Homes Are Different
Glendora sits tight against the San Gabriel foothills, and that position changes the work in ways that don’t apply to Glendora’s flatland neighbors. The Valley Fire of 2020 burned the ridgelines directly above town, and the ash and debris that followed pushed thousands of Glendora homeowners to get chimneys and flues inspected. Foothill canyon homes in the 91741 ZIP, especially older custom builds with original brick chimneys, absorbed the worst of the post-fire debris-flow muck. We regularly find cracked crowns and rusted caps on hillside chimneys where debris sat against the masonry through wet winters, then dried into hard crusts during Glendora’s long summer heat.
The housing stock compounds it. Glendora’s 1950s through 1970s tract homes in 91740 were built with serviceable clay tile liners that are now six or seven decades old. Those liners crack. Mortar joints erode. Crowns spall from decades of Santa Ana-driven temperature swings. Meanwhile the custom foothill homes in 91741 often have hillside chimneys with more masonry surface area exposed to weather, which means more places for water to get in and do damage. Glendora’s dry, hot summers followed by occasional winter fireplace use also create a specific creosote pattern: long dry spells let residue harden in the flue, then a few cold snaps bring heavy use and rapid buildup. None of this is theoretical. We see it on a weekly basis in Glendora, and it means our repair work here leans heavier toward liner replacement and crown restoration than in valley cities a mile south.
Styles & brands we work with





Our Main Glendora Services
Two services account for most of the calls we get from Glendora homeowners: full chimney sweeping and dryer vent cleaning. Both are fire-prevention work first, and both benefit from the same repair-grade inspection standard we bring to every visit.
Chimney Sweep in Glendora
Glendora fireplaces that get used through the winter, then sit through the long dry season, develop a hardened creosote we see more often here than in coastal cities. Our chimney sweep in Glendora removes that buildup and checks the flue for cracks and blockages at the same time. In foothill homes near the Angeles National Forest boundary, we also check for ash intrusion and debris that may have worked into the stack since the last burn season. A sweep is the baseline. The inspection that comes with it is where Glendora homeowners learn whether they need more. Chimney Sweep in Glendora

Dryer Vent Cleaning in Glendora
Clogged dryer vents are one of the leading causes of residential fires nationwide, and Glendora’s older laundry rooms often route vents through long runs to exterior walls or roof lines. Lint packs into those runs over time, and a gas dryer pushing against a blocked vent is a carbon monoxide risk as well as a fire risk. Our dryer vent cleaning removes the accumulated lint and confirms airflow at the termination point. It is a small job that prevents a large problem. Dryer Vent Cleaning in Glendora

Chimney Repair in Glendora
Glendora’s chimney repair needs track closely with housing age and the San Gabriel foothill climate. In 91740, mid-century tract homes with original clay tile liners are hitting the point where cracks and gaps let heat reach combustible framing. In 91741, foothill canyon homes show crown damage and cap rust accelerated by Valley Fire ash and debris-flow saturation, followed by the harsh drying cycles of Glendora summers. Whether it is a cracked liner, a failed crown, or a flashing leak at the roofline, we diagnose the problem with camera inspection and repair it using professional materials from Olympia Chimney, Famco, and Copperfield. Chimney Repair is our core service, and in Glendora most repair jobs start with two findings: water entry at the top of the chimney, or flue deterioration visible only by camera. Here is what those repairs actually involve.
Chimney Crown Repair
Signs you need it
You see cracked, crumbling, or missing mortar across the flat concrete surface on top of the chimney, or water staining on the ceiling near the fireplace.
What it costs in Glendora
Chimney crown repair in Glendora typically runs $165 to $450 depending on the crown’s size and the extent of mortar loss.
How we do it
We remove the deteriorated surface material, build a proper crown form with the correct slope and drip edge, and seal it with a weatherproof crown coat that handles Glendora’s extreme heat without cracking.
Chimney Liner Installation
Signs you need it
A camera inspection shows cracks, gaps, or spalling in the existing clay tile liner, or you notice chunks of tile at the bottom of the fireplace.
What it costs in Glendora
Chimney liner installation in Glendora ranges from $1,500 to $2,900 depending on flue height, liner diameter, and whether the chimney is straight or offset.
How we do it
We size a stainless steel liner to the flue’s exact dimensions and appliance requirements, lower it through the chimney, insulate as needed, and connect it at the appliance and termination point so the system vents safely.

What Glendora Customers Say

— Diego Delgado"Good work. The written inspection report took about a week to arrive after I asked for it, which was slower than I expected."
