Introduction

Warren sits at the edge of the Nickel Belt—close enough to Sudbury for mining families to commute, far enough east to feel like a distinct community. Since the 1960s, when the population grew alongside the mining industry, Warren and the surrounding Markstay-Warren area have been home to working families who value practical, reliable service.

The homes here reflect that heritage. Built solid for families who work hard and expect the same from their service providers. No flashy sales pitches needed—just show up on time, do quality work, and charge a fair price. That’s exactly how Mason Cleaning Systems has operated since 1981.

Located on Highway 17 between North Bay and Sudbury, Warren falls within our regular service territory. We’ve been cleaning ducts, clearing dryer vents, and maintaining chimneys throughout Sudbury East for over four decades. Chimney service has been central to our business from the beginning—we understand wood heat because Northern Ontario demands it.

Air Duct Cleaning in Warren

Warren's housing stock tells the story of a community built for working families. Many homes date from the 1960s growth period when proximity to Sudbury's mines made this an attractive place to raise a family. Those established homes have ductwork that's been circulating air for decades—accumulating dust, allergens, and debris with every heating season.
The Established Home Reality:
Homes built in the 1960s and 1970s have ductwork approaching 50-60 years of service. Even well-maintained systems accumulate significant buildup over that timeframe. Forced air heating circulates everything in the air—dust, pet dander, pollen, household particulates—and deposits a portion with each cycle. Multiply that by decades, and the accumulation is substantial.
The Northern Ontario Factor:
Our long heating season—seven to eight months of furnace operation—means more air circulation, more filtration demand, and more accumulation than southern Ontario homes experience. Warren's climate accelerates the need for periodic professional duct cleaning.
Our 5,000 CFM Advantage:
We don't use residential-grade equipment. Our commercial extraction system pulls 5,000 cubic feet of air per minute—enough power to create genuine negative pressure throughout your entire duct system. Triple-stage filtration captures 99.9% of everything we extract. The result: decades of buildup removed, not just stirred around.
What to Expect:
Complete assessment of your duct system configurationSealing of all registers to maintain system-wide suctionMechanical agitation combined with continuous extractionMain trunk line and branch cleaningOptional organic sanitization treatmentFinal airflow verification at each register
Ideal For:
Spring opening — clear winter's accumulation before occupancyFall closing — remove the season's debris before shutdownAfter conversion to year-round use — clear construction debrisFollowing extended vacancy — remove dormancy accumulation

Dryer Vent Cleaning in Warren

Lint buildup is the number one cause of residential dryer fires across Canada. It's a straightforward problem with a straightforward solution—but it requires proper equipment and professional attention to address completely.
The Fire Prevention Reality:
Every load of laundry sends lint through your dryer vent. The lint trap catches most of it, but not all. Over time, the remainder accumulates in the vent line—especially at bends, joints, and the exterior termination. That accumulated lint is highly flammable. Combined with a dryer generating heat, the fire risk is real and documented.
The Established Home Configuration:
Homes built when Warren's population grew often have dryer vents routed based on where the laundry room was located—not necessarily the shortest or most efficient path to exterior. Longer runs, multiple direction changes, and vents passing through unheated spaces are common. These configurations accumulate lint faster and require professional clearing.
Our 250 PSI Air Compressor System:
Using specialized air whips powered by our 250 PSI compressor, we clear the entire vent run from dryer connection to exterior exhaust. This equipment handles the challenging configurations common in established homes—long runs, multiple bends, compacted buildup. Complete clearing, verified before we leave.
Warning Signs You Need Service:

Chimney Cleaning & Inspections in Warren

Wood heat remains common throughout Warren and Markstay-Warren. Whether it's a primary heat source, supplemental warmth during the coldest stretches, or simply the comfort of a wood fire on winter evenings—these systems require professional maintenance to operate safely.
The Creosote Reality:
Every wood fire produces creosote—it's unavoidable. This tar-like substance deposits on flue walls with each burn. The rate of accumulation depends on burning practices, wood moisture content, and appliance efficiency, but accumulation happens regardless. Just 1/8 inch of buildup creates significant fire hazard. Regular professional cleaning removes this hazard before it becomes dangerous.
The Established Home Chimney:
Chimneys in Warren's established homes have often provided decades of reliable service. That longevity is a testament to solid construction, but even well-built chimneys require maintenance. Mortar joints weather over time. Tile liners can develop cracks from repeated heating and cooling cycles. Caps and crowns deteriorate from exposure. Regular inspection catches these issues before they become problems.
Practical Approach:
We tell you what we find—clearly and directly. If something needs attention, we'll explain what and why. If everything checks out, we'll tell you that too. No unnecessary upselling, just honest assessment and professional service.

WETT Inspections in Warren

Insurance companies recognize WETT inspections as the standard for wood-burning appliance safety. If you have a wood stove, fireplace insert, or wood-burning fireplace, your insurance provider may require WETT certification for coverage—especially at renewal or when purchasing a new policy.
What is WETT?
Wood Energy Technology Transfer (WETT) is the Canadian program that establishes safety standards for wood-burning installations. A WETT inspection examines your complete system—appliance, chimney, clearances to combustibles, and connections—against these standards. The resulting documentation satisfies insurance requirements throughout Ontario.
David Mason's Credentials:
David Mason holds both WETT Inspector and WETT Installer certifications. This dual credential means thorough inspection combined with practical understanding of installation requirements. We've worked with wood-burning systems throughout Northern Ontario since 1981.
Straightforward Process:
We inspect, we document, we provide the certification your insurance company needs. No complicated procedures—just thorough professional inspection and clear reporting.
