About Mason Cleaning Systems Inc.
Northern Ontario’s Fire Prevention & Indoor Air Quality Authority Since 1981
Northern Ontario’s Fire Prevention & Indoor Air Quality Authority Since 1981
Mason Cleaning Systems Inc. is not a franchise.
We are a family-owned Northern Ontario company, founded in 1981, built around one purpose: protecting homes and buildings from fire hazards and poor indoor air quality.
For more than 45+ years, we’ve worked in attics, crawl spaces, boiler rooms, mechanical chases, and rooftops across the Near North. We don’t experiment. We apply a proven process using professional equipment, certified inspections, and one-trip reliability.
The Mason Difference: We’re Technicians, Not “Cleaners”
Most companies clean what you can see.
We address what insurance companies, fire investigators, and HVAC engineers worry about.
- Creosote buildup that leads to chimney fires
- Lint accumulation—the #1 cause of dryer fires
- Dust, dander, and mold circulating through forced-air systems
- Uncertified wood-burning appliances that can void insurance coverage
That’s why homeowners, insurers, and property managers across Northern Ontario rely on Mason Cleaning Systems when safety matters.
Founded by Experience — Led by Certification
Mason Cleaning Systems was founded by David Mason, a WETT-Certified Inspector and Installer with decades of hands-on field experience.
WETT (Wood Energy Technology Transfer) certification is the only chimney and wood-burning inspection standard recognized by insurance companies. Many companies can sweep a chimney. Very few can legally certify it. That distinction matters when:
WETT (Wood Energy Technology Transfer) certification is the only chimney and wood-burning inspection standard recognized by insurance companies. Many companies can sweep a chimney. Very few can legally certify it. That distinction matters when:
- You’re renewing home insurance
- Buying or selling a property
- Installing or modifying a wood-burning appliance
- Protecting your family during a Northern Ontario winter
The 5,000 CFM Standard (Why Our Equipment Matters)
We don’t use portable shop-vacs or homeowner equipment.
Our trucks carry 220-volt, commercial vacuum systems that generate 5,000 cubic feet of air movement per minute. That power creates true negative pressure across your entire duct system or flue.
What that means for you:
What that means for you:
- Dust and debris are extracted, not blown around
- All contamination exits the building to the truck unit outside
- Registers stay sealed throughout the process
- Your home is cleaner when we leave than when we arrived
This is the same standard required in hospitals, commercial buildings, and institutional facilities—and it’s what we bring to every residential job.
