Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Call (855) 360-4975 and we’ll walk you through what to expect.
Why Chestnut Chimney Sweep Is Glendora’s Preferred Chimney Sweep Company
Roland Cifuentes started Chestnut Chimney Sweep with a simple rule: never recommend a repair a homeowner can’t verify with their own eyes. That matters in Glendora, where the housing stock leans heavily toward 1950s – 1970s tract and custom homes with original brick masonry fireplaces. We’ve climbed onto roofs along Foothill Boulevard, worked inside homes in the historic downtown grid, and serviced newer builds in the north foothills. Our Chimney Sweep team knows the difference between a flue that needs a rebuild and one that just needs a level eye and a good brush.
Customers in Glendora consistently tell us the same thing: they appreciate that we don’t guess. When we open a firebox off East Foothill or up near Sierra Madre Avenue, we run a camera before making any recommendation. You see what we see. That’s the only way to do this job honestly. Our Glendora customers get the same treatment as everyone else: named parts, clear pricing, and no scare tactics.
Response time to Glendora runs 3 – 5 business days for routine sweeps, and we’re faster in late summer when the fireplaces are idle. For anything involving a blocked cap after high winds, we try to slot you in sooner.

Chimney Services in Glendora
Chimney Services in Glendora start with understanding what kind of system you have, because a 1960s clay-tile flue needs different care than a factory-built metal unit in a 1990s north foothill development. A basic sweep and Level 1 inspection runs $189 – $249. If you need a Level 2 camera inspection, expect $249 – $349. Those are honest ranges for this market, not bait numbers. What you pay depends on flue height, creosote stage, and whether we’re dealing with debris from the last wind event. A service call typically takes under two hours, and we’ll show you photos before and after.
Level 1 and Level 2 Inspections
A Level 1 inspection happens during every sweep and covers the visible portions of the chimney, from firebox to cap. A Level 2 inspection uses a camera to look inside the flue liner, and is what you need if you just bought a mid-century home in Glendora, if you had a chimney fire, or if you suspect water damage. We recommend Level 2 for any home with its original clay tile flue.

Creosote and Soot Removal
Creosote isn’t all the same. First-degree is brushable soot. Third-degree is a tar glaze that hardens to the flue wall and shrugs off a standard wire brush. We see third-degree in older Glendora fireplaces every week. Chemical treatments and mechanical removal work, but sometimes the honest answer is a liner repair, not another sweep.

Chimney Sweep Certified in Glendora
Chimney Sweep Certified work in Glendora means the sweep uses a camera, records what he finds, and specifies materials by name rather than writing “fix chimney” on an invoice. Our annual sweep runs $189 – $249 for a standard open masonry fireplace, which covers the flue brush, smoke chamber cleaning, firebox cleanup, and cap check. We’re certified in HeatShield restoration, which means we can often repair a cracked clay liner from the inside rather than tearing out your living room wall to replace it. That capability saves Glendora homeowners thousands, and most sweep-only companies don’t offer it.
Annual Sweep Program
If you burn wood more than twice a week between November and March, book an annual sweep every September. The flue gets a full brushing, the smoke chamber gets vacuumed, and we check the spark arrestor before wind season arrives. After a Santa Ana event, a quick inspection is worth doing even if you haven’t burned anything recently.
Post-Wind Inspection
Given Glendora’s position at the base of the San Gabriel Mountains, post-Santa Ana inspections have become a standard part of our work here. Palm fronds, eucalyptus leaves, and the occasional ember lodge in the cap and arrestor on foothill roads. That debris blocks draft and creates a real fire hazard. We clear it, inspect the screened cap, and run the camera if anything looks off.
Trusted Brands We Service in Glendora
We carry DuraFlex, Copperfield, Gelco, and Olympia Chimney components because the parts matter as much as the labor. When a Glendora customer needs a new chimney cap or a screened spark arrestor after wind season, we don’t run to a hardware store for a generic substitute. HeatShield is our go-to for liner restoration on aging clay flues, especially in the 91741 foothill neighborhoods where replacing a liner through the firebox would mean serious masonry work. Roland Cifuentes keeps a tight stock of common parts for Glendora jobs, so most repairs finish in one visit.

AfterCommon Chimney Sweep Problems We See in Glendora Homes
- Third-degree creosote glaze in original clay flues. Homes built between 1950 and 1975 often have unlined or clay-tile flues that hold heat and condense creosote badly. A brush won’t touch it. Chemical removal or HeatShield restoration is the fix.
- Spalling mortar and cracked firebrick. Glendora’s hot, dry summers expand and contract masonry, and 60-year-old fireboxes show it. Spalling mortar weakens the chimney’s structural integrity and lets heat reach framing.
- Blocked chimney caps after Santa Ana winds. Foothill properties near the mountain base collect palm fronds and leaves in spark arrestors. That blocks draft, pulls smoke into the house, and invites embers to enter.
- Misdiagnosed flue cracks by other companies. We’ve lost count of how many Glendora homeowners were told they needed a full liner replacement when a camera inspection showed minor mortar erosion. We show you the footage. You decide.

FAQs About Chimney Sweep in Glendora
At least once a year, and ideally twice if your home sits in the foothill-facing neighborhoods where Santa Ana winds deposit debris into caps and arrestors. Book a sweep every September before burn season, then a visual cap check after any major wind event. The second check takes us 15 minutes.
Call (855) 360-4975 and we’ll put you on the pre-season list.
You won’t know without a Level 2 camera inspection. Cracks hide behind soot and glaze. We run the camera, show you the footage on our monitor, and point to exactly what we see. If the cracks are minor, HeatShield repair often eliminates the need for a full rebuild.
Call (855) 360-4975 to schedule a Level 2 inspection and see the flue for yourself.
First-degree creosote is dry, flaky soot that brushes off easily. Third-degree is a hardened tar glaze that melts and re-solidifies, bonding to the flue wall. It’s a fuel source that burns at extreme heat and requires chemical treatment or liner replacement, not another pass with a brush.
If the inside of your flue looks like melted black glass, call (855) 360-4975 for an honest assessment.
Yes, and it’s one of the most common calls we get after a Santa Ana event. We remove the lodged debris – palm fronds, leaves, sometimes small branches – clean the cap and arrestor, and run a quick smoke test to confirm the draft is restored. Most of these jobs are resolved in a single visit.
If your fireplace is smoking back into the room after a wind event, call (855) 360-4975 and mention the wind damage. We’ll prioritize the inspection.
Yes, we do. Factory-built and pre-fab metal fireplaces in the north foothills have different clearances, cap requirements, and flue dimensions than masonry units, and we carry the components to service them correctly. A sweep runs $179 – $229 for these systems.
Call (855) 360-4975 with the brand and model if you have it, and we’ll confirm the right parts before we arrive.
