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.

Why Ontario Homes Are Different
Ontario’s housing stock spans a century of construction styles, and that changes how we approach chimney cleaning here. Homes built before 1970 in neighborhoods like the Historic Euclid Avenue district and the older grid streets south of downtown often have masonry fireplaces with clay tile liners. Those liners absorb creosote differently than the stainless steel liners found in newer builds, and older fireboxes tend to collect more debris from decades of use. Homes in newer developments east of Haven Avenue and north toward the 10 freeway typically have factory-built or prefabricated fireplaces, which need a different inspection approach and different types of brush heads. Ontario sits in the Inland Empire’s high-fire-risk territory, where Santa Ana winds move through the foothills in fall, and a clean chimney matters more here than in coastal cities. Dry conditions and wind-driven embers make a properly maintained chimney part of responsible homeownership in this city specifically. We also see more roof access challenges in Ontario’s older neighborhoods, where steep gable rooflines and mature trees require ladder work that an untrained person should never attempt. Hank Delano and our Ontario crews know which neighborhoods have tight access alleys behind garages and which areas have newer construction with wider chimney clearances.
Our Main Ontario Services
Most Ontario homeowners call us for one of two things: a chimney sweep before their first fire of the season, or an inspection because they just bought or sold a house and the report flagged the fireplace. Every job below gets a written price before work starts and the full Garrison Standard on every visit.
Chimney Sweep in Ontario
A standard chimney sweep in Ontario removes the creosote and soot that build up inside your flue, which is the vertical passage that carries smoke out. Ontario’s dry fall weather means creosote cures hard and fast, and hard creosote is what fuels chimney fires. Our sweep includes drop cloths at the hearth, a HEPA-filtered vacuum running throughout, and a visual check of the firebox and cap while we’re on the roof. We background-check and uniform every technician, and the final invoice matches the price you approved before we started. Chimney Sweep in Ontario
Chimney Inspection in Ontario
An inspection in Ontario documents the condition of your flue, crown, cap, and firebox, usually as part of a real estate transaction or after you’ve noticed something odd like water stains on the ceiling near the chimney. We inspect per National Fire Protection Association standards, and you get a written report with photos showing exactly what we found, not just a checkbox summary. Ontario’s clay tile liners in older homes are the most common thing we flag during inspections here. If the liner is cracked, we tell you plainly whether it’s urgent or whether it can wait.

Chimney Repair in Ontario
Chimney repair work in Ontario runs from crown resealing and cap replacement to flue relining, which means replacing the inner liner that channels smoke safely out of the house. Water is the main thing that damages chimneys in Ontario, not fire. Cracks in the crown let rainwater seep into the masonry, and that freeze-thaw cycle during the few cold weeks each winter widens the crack. Every repair comes with our 365-Day Done Right Promise: if a covered repair fails within one year, we return at no charge. Chimney Repair in Ontario

Two things push the price up in Ontario more than anything else: roof pitch on older homes and the condition of the liner once we get a camera inside. Steep access is slower work and sometimes requires additional safety rigging. When a clay tile liner has collapsed, we don’t patch it; we tell you what a reline costs and put the numbers in writing so you decide with facts, not pressure.
