We’ve been driving out to San Dimas since 1984 - long before the 210 freeway expansion made the trip faster. Our dispatch routes through Via Verde, San Dimas Avenue, and the foothill streets near San Dimas Canyon Road daily. We know which ranch-style homes on the north side have the original 1960s masonry fireplaces that never came with spark arrestors, and we know the LA County Fire Code requirements that now mandate them.

Why Hearthstone Chimney Co. of Los Angeles Is San Dimas’s Preferred Chimney Cleaning & Sweep Company
San Dimas homeowners don’t call us because we’re the cheapest. They call because their neighbor on Cataract Avenue had us out last winter, or because their contractor mentioned our name after seeing our inspection photos. After 42 years, our reputation in this city is built on showing up when we say we will and documenting what we find so there’s no argument later.
We answer the phone with a live person, every hour of every day. No voicemail, no callback queue. Our background-checked, uniformed technicians complete most San Dimas jobs in a single visit because we stock professional-grade materials from Olympia Chimney, Famco, and Copperfield on every truck. No-hassle upfront pricing means the number on your estimate matches the number on your invoice.
Our Chimney Cleaning & Sweep in San Dimas service is backed by the 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork, no arguing. That’s the Keystone Standard we’ve operated under since 1984.
Our Chimney Cleaning & Sweep Services in San Dimas
Level 1 Inspection
A Level 1 inspection in San Dimas runs $189-$249 and covers all readily accessible portions of your chimney structure and flue. For the ranch-style and tract homes that dominate this city - most built between the late 1950s and early 1980s - this is the minimum annual check required by the National Fire Protection Association. We examine the firebox, damper, smoke chamber, and exterior masonry for creosote buildup and obvious structural defects. If your home is on the foothill side near San Dimas Canyon, we’ll also verify whether your spark arrestor meets current LA County Fire Code, since many original installations predate the requirement.
Level 2 Inspection
A Level 2 inspection in San Dimas costs $289-$389 and includes everything in Level 1 plus a full internal camera scan of the flue liner. This is what we recommend for any San Dimas home that’s changed hands, suffered earthquake damage, or gone more than five years without professional service. Decades of Southern California seismic activity along nearby fault systems open hairline cracks in older brick fireboxes and mortar joints. Our camera finds what a visual sweep misses. You get photos you can see and a plain-English verdict. We document like engineers, explain like craftsmen.
Creosote Removal
Heavy creosote removal in San Dimas ranges from $249-$449 depending on glaze thickness and flue accessibility. The foothill elevation here produces cooler nighttime temperatures than the flatlands to the south, so residents burn more frequently from November through March and build up more creosote than coastal LA homeowners. Santa Ana wind events funneling through San Dimas Canyon make this buildup especially dangerous - a hot ember riding those winds can travel hundreds of feet. We use rotary cleaning systems and professional-grade solvents to remove glazed creosote that standard brushes won’t touch.
Soot Removal & Annual Sweep
A standard soot removal and annual sweep in San Dimas costs $189-$279 and should be scheduled every year for wood-burning fireplaces, every 50 fires minimum. Many San Dimas homeowners in the 91773 ZIP have never had their original masonry fireplace professionally cleaned. The 1960s-70s construction era means these systems have decades of accumulation. Our annual sweep service includes debris removal from the smoke chamber and firebox, damper cleaning and lubrication, and a basic structural check. We finish with a written condition report.

Trusted Brands We Service in San Dimas
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from Olympia Chimney, Famco, and Copperfield - the brands that other sweeps in San Dimas often have to order and make you wait for. When we find a rusted-out spark arrestor on a Via Verde ranch home or a cracked flue liner in a 1970s tract house off San Dimas Avenue, we replace it from stock on the spot. That means most San Dimas jobs finish in one visit, not two. The spark arrestor we installed on that foothill home was a Copperfield stainless-steel screen rated for high-wind ember exposure. It’s the right part for this city’s fire hazard conditions.
Common Chimney Cleaning & Sweep Problems We See in San Dimas Homes
- Missing or rusted spark arrestors violating LA County Fire Code. Many original 1960s-70s masonry chimneys in the San Dimas foothills were built before spark arrestor requirements were enforced in fire hazard zones. We routinely find either no screen at all or a fully rusted-out original mesh. This is a code deficiency that must be corrected before legal use.
- Seismic cracks in brick fireboxes and mortar joints. Decades of earthquake activity along regional fault systems damage masonry that looks fine from the outside. Our Level 2 camera inspections catch hairline fractures that visual-only sweeps miss entirely.
- Heavy glazed creosote from regular winter burning. Cooler foothill nights mean more fires, more often, building up hard glazed layers that standard brushing won’t remove. This requires rotary tool cleaning and sometimes chemical treatment.
- Ember hazards during Santa Ana wind events. The canyon geography funnels intense winds through San Dimas during fall and winter. An uncleaned flue or missing spark arrestor becomes a neighborhood-level ignition source. This isn’t theoretical - it’s why CAL FIRE classifies this area Very High Fire Hazard.

FAQs - Chimney Cleaning & Sweep in San Dimas
Yes. LA County Fire Code mandates spark arrestors on all chimneys within CAL FIRE’s Very High Fire Hazard Severity Zone, which covers the foothill and canyon-adjacent portions of San Dimas. We verify spark arrestor presence and condition during every inspection, and we carry replacement screens on our trucks for same-day installation if yours is missing or rusted through. Call (844) 418-0954 and we’ll check yours during your next sweep.
Once per year minimum, or every 50 fires, whichever comes first. Because San Dimas’s foothill elevation produces cooler nights than coastal LA, most wood-burning residents here fire up more frequently from November through March and accumulate creosote faster. We recommend scheduling before the Santa Ana wind season begins in fall. Our $89 Seasonal Tune-Up is designed for this timing.
Missing or failed spark arrestors combined with heavy creosote buildup in original 1960s-70s masonry systems. We serviced a ranch-style home on Via Verde in the foothills where the 1960s chimney had a fully rusted-out original spark arrestor mesh and a heavy creosote glaze from decades of use. We replaced the spark arrestor with a new Copperfield stainless-steel screen and performed a Level 2 inspection plus a full creosote removal using our rotary tools, all in one trip. The homeowner appreciated not having to schedule a second visit for the code-mandated repair.
Yes. Our Level 2 inspection with internal camera scan is available throughout San Dimas, including the foothill neighborhoods near San Dimas Canyon and the older tract areas off San Dimas Avenue. We recommend Level 2 for any home that’s changed ownership, experienced earthquake activity, or gone more than five years without professional inspection. The camera finds cracks and liner damage that visual checks cannot. Call (844) 418-0954 to schedule - we typically have availability within 48 hours.
Yes, significantly. The San Dimas Canyon geography funnels Santa Ana winds directly through residential areas, carrying embers from uncleaned flues or missing spark arrestors hundreds of feet to neighboring properties. CAL FIRE’s Very High Fire Hazard Severity Zone designation for this area is based on this exact combination of fuel load, terrain, and wind pattern. A clean flue with a proper spark arrestor is your best defense. We check both during every San Dimas service call. Call (844) 418-0954 for a free estimate.
