Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across San Dimas
A standard chimney sweep in San Dimas runs $189 – $289 for a wood-burning fireplace and $149 – $229 for a gas log set, and the job typically takes 45 to 90 minutes from setup to final vacuum. We book a specific arrival window, not “sometime between 8 and 5,” and the price you approve before booking is the price on the invoice. If you live in San Dimas, our crews know the foothill streets, the 91773 ZIP, and the older masonry stacks that came with the original tracts. Call (830) 251-4560 and a live person answers.
Why Flint Chimney Sweep Is San Dimas’s Preferred Chimney Sweep Company
Flint Chimney Sweep has been part of the Garrison Partners family since 2002, and we built our reputation in San Dimas on showing up inside the window and leaving the house cleaner than we found it. Every technician who walks through your door is background-checked and uniformed, so you know exactly who is working in your home before they arrive. Hank Delano leads our crews, and he holds every job to The Garrison Standard: a written price before any work starts, a camera inspection with a photo report, and a written guarantee on any repair we recommend.
What San Dimas homeowners tell us they want is a straight answer. They have been burned by companies that quote low over the phone, then discover a “problem” once the tech is on the roof. So we put the scope in writing before the truck moves. The Chimney Sweep team documents what we find with photos, and if we find something that needs repair, you see the camera image yourself before you spend a dollar.
Our 365-Day Done Right Promise applies to every repair we perform in San Dimas. If a covered repair fails within one full year, we return at no charge. No argument, no re-diagnosis fee. That is the written guarantee, and it is the same one every Garrison Partners location honors.
Gas Fireplace Cleaning in San Dimas
Gas Fireplace Cleaning in San Dimas usually means pulling the log set, brushing and vacuuming the firebox, inspecting the damper and cap, and running a camera up the flue to check the liner and mortar. Because so many San Dimas homes vent gas log sets into masonry chimneys built before the foothill tracts filled in, the firebox often looks spotless while the flue has been quietly weathering for decades. A gas fireplace cleaning here runs $149 – $229, and it is not the same thing as a Level 2 inspection, which we recommend if the flue has never been camera-checked.
What the Log Set Cleaning Covers
We remove the gas logs, vacuum the firebox, and clean the burner ports so the flame pattern is even. Then we check the damper linkage and look for soot buildup or corrosion on the gas valve. If the glass front is hazy, we clean it with the right compound for the glass type, not whatever is on the truck.
Why the Flue Still Matters on a Gas Chimney
A gas-only flue does not produce creosote, but it does take the same rain, wind, and freeze-thaw cycles as any other stack. Mortar spalls, liners crack, and chimney crowns fail without ever showing a hint of smoke in the house. The only way to know is to look, and that means a camera, not a flashlight from the roof.
Chimney Maintenance in San Dimas
Chimney Maintenance in San Dimas covers the annual sweep, the cap and flashing check, and a written condition report we leave with you after every visit. The point is to catch small problems before they become invoice-sized ones. A maintenance visit in San Dimas typically runs $189 – $289 for a wood-burning chimney, and we recommend it every year if you burn wood, and every two to three years if you only run gas logs.
The Camera Report You Keep
After we sweep, we run a borescope up the flue and photograph the liner, smoke chamber, damper, and crown. You get a written photo report showing exactly what is there. If something needs attention, you see the image and we give you a written price for the repair. If nothing needs attention, you know that too, and you have the report to prove it.
Cap and Flashing Check
Foothill wind off the San Gabriels works on chimney caps and flashing more than people expect. Loose caps let rain into the stack, and the freeze-thaw cycle above 1,000 feet turns small cracks into spalled mortar. We tighten, seal, and note anything marginal on the report, so it is on record before it becomes a leak.
Trusted Brands We Service in San Dimas
We install and service professional-grade chimney products, and we specify by job, not by margin. For San Dimas homes with gas log sets venting into old masonry flues, HeatShield resurfacing is often the most cost-effective liner repair because it restores the existing clay liner without a full teardown. We also work with Gelco chimney caps and Olympia Chimney liners when the job calls for replacement. Because we stock common parts locally, turnaround on cap swaps and damper repairs in San Dimas is usually a matter of days, not weeks.
Common Chimney Sweep Problems We See in San Dimas Homes
- Spalling smoke chambers gone unseen. A gas log set never produces smoke, so nobody notices the mortar flaking away above the firebox. By the time a ceiling stain appears in a San Dimas living room, the damage has usually been years in the making.
- Second-degree creosote in wood-burning inserts. Foothill homeowners who burn oak or eucalyptus on low, slow fires build flaky creosote faster than people in the flatlands. It brushes out cleanly at stage two, but left alone it becomes glaze that a brush will not touch.
- Failed chimney crowns from foothill weather. Wind-driven rain off the San Gabriels beats on caps and crowns. A cracked crown lets water into the stack, and the freeze-thaw cycle does the rest. We photograph every crown on every visit because it is the cheapest fix we catch.
- Gas fireplaces that get cleaned but never inspected. The log set is wiped down and the visit is called done, but the liner, damper, and cap were never actually checked. That is a surface cleaning, not a Level 2 inspection, and it misses the problems that actually matter.

FAQs About Chimney Sweep in San Dimas
No, an annual camera inspection is not necessary for a gas-only chimney, but we recommend one every two to three years. Gas log sets do not create creosote, so the danger is not in the flue deposits. What you need to watch is the chimney structure itself, because San Dimas sits against the San Gabriels and takes wind-driven rain and freeze-thaw cycles that stress mortar, crowns, and flashing. A Level 2 inspection with a photo report every few years gives you a record of what is changing, so small cracks stay small. Call (830) 251-4560 and we will tell you over the phone whether an annual visit is worth it for your specific setup.
Every 25 to 35 fires, or at minimum once per burning season if you burn regularly from November through March. The number that matters is creosote thickness, not calendar months. First-degree creosote is a light dusting and brushes out easily. Second-degree is flaky and needs a real sweep. Third-degree is a hard glaze that a brush will not remove, and it is a chimney fire waiting for a spark. We include a creosote measurement on every report so you know where your flue stands. Call (830) 251-4560 to schedule a sweep, and we will tell you honestly whether it could have waited.
A Level 1 inspection is a visual check of the accessible parts of the fireplace and chimney, and it is included with every sweep. A Level 2 inspection adds a camera scan of the full flue interior, plus the exterior crown, cap, and flashing, and you get a written photo report. If you have only ever burned gas logs, or you just bought a San Dimas home, or we are coming out after a storm or an earthquake, a Level 2 is the one that actually tells you what is going on inside the stack. The Level 2 runs $75 – $150 when bundled with a sweep. Call (830) 251-4560 and we will tell you which level fits your situation before you book.
Yes, the price is set in writing before we book the appointment, and it is the exact number on the invoice. A wood-burning sweep in San Dimas runs $189 – $289, and a gas fireplace cleaning runs $149 – $229. If we find something during the camera inspection that needs repair, you see the photo and get a separate written price before any repair work happens. Nothing gets added to the invoice without your written approval first. Call (830) 251-4560, tell us what you have got, and we will give you the number on the spot.
Yes, you get a written photo report after every sweep and inspection in San Dimas. The report shows the condition of the liner, smoke chamber, damper, crown, and cap at the time of the visit, with images and notes. If we perform any repair, that repair gets its own written guarantee, valid for one full year from the service date, under our 365-Day Done Right Promise. If a covered repair fails within that year, we return at no charge. You leave every Flint visit with documentation, not just a receipt. Call (830) 251-4560 and we will walk you through exactly what the report includes.
