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 Ontario, CA
Chimney cleaning in Ontario, CA typically costs between $189 and $289 for a standard sweep, and most inspections run $149 to $349 depending on the level. Ontario’s mix of post-war ranch homes and 1970s-80s tract builds means we see a lot of original masonry chimneys and clay tile liners that haven’t been looked at in years. Our crews work across Ontario weekly, and we answer every call with a live person at (831) 218-8547.
Why Ontario Homes Are Different
Ontario’s housing stock creates a specific kind of chimney job. The post-war ranch-style homes and 1970s-80s tract builds across central Ontario often have original masonry chimneys with clay tile liners. Those liners can crack during the rare heavy rain or minor seismic activity that occasionally moves through the Inland Empire. The semi-arid climate means chimneys here don’t see much moisture, but Santa Ana winds push debris and embers into unused flues, and when a cold snap hits, families light the first fire of the season in a chimney that’s been sitting with that debris for months. In the historic Euclid Avenue district, many chimneys have decorative brickwork that needs careful handling so the facade isn’t damaged during a sweep. And because Ontario’s mild winters mean fireplaces go unused most of the year, creosote isn’t usually the main concern. We’re more often clearing out animal nesting, cracked flue tile fragments, and years of accumulated dust and debris.
Styles & brands we work with





Our Main Ontario Services
Most Ontario homeowners call us for one of three reasons: a chimney that hasn’t been cleaned in years, a home purchase or sale that needs an inspection, or a fireplace that won’t draw or ignite properly.
Chimney Sweep in Ontario
In Ontario, a sweep usually starts with protecting the floors and furniture before anything else. Our technicians lay drop cloths, put on shoe covers, and set up containment before touching the flue. Because so many Ontario chimneys sit unused through the long warm season, we’re often removing more than soot: bird nesting, leaves, and debris that Santa Ana winds pushed into the flue. We also check for cracked clay tiles, which are common in the original masonry chimneys of post-war ranch homes here. Pet-safe products are used where there is a choice, and you get a photo of the clean-up before we leave. For full details, see Chimney Sweep in Ontario.

Chimney Inspection in Ontario
Ontario home sales in the 1970s-80s tract neighborhoods often trigger a chimney inspection, and for good reason: those original clay liners may not have been looked at since the home was built. We perform Level 1 inspections for routine checkups and Level 2 inspections when a property is changing hands or after weather events. Given Ontario’s mild climate and long stretches of disuse, the most common findings are missing or cracked flue tiles, animal debris blocking the flue, and build-up from the occasional first-use fire. You see photos of everything we find. Get the full scope at Chimney Inspection in Ontario.

Fireplace Repair in Ontario
Ontario’s older fireplaces run into trouble with damper operation, cracked firebrick, and deteriorating mortar joints. In homes along the Euclid Avenue corridor, repairs often involve preserving the decorative brick surround while addressing the functional issue behind it. We use professional-grade materials including HeatShield and DuraFlex for liner repairs, and Gelco for waterproofing where needed. Every repair gets a written price before work starts, and the 365-Day Done Right Promise covers the result. Details are on the Fireplace Repair in Ontario page.

What pushes a price up in Ontario is usually access: two-story tract homes with steep rooflines in the 1970s-80s subdivisions take longer to work safely than single-story ranch homes. Decorative brickwork on Euclid Avenue facades also adds care time. Every job gets a written price before work begins, and that price includes shoe covers, drop cloths, and the clean-up photo.
