Air Duct, Dryer Vent & Chimney Cleaning in Muskoka
Professional cleaning and WETT certification services for Muskoka cottages and year-round homes since 1981. Our 5,000 CFM commercial vacuum systems deliver thorough results. Serving Huntsville, Bracebridge, Gravenhurst, and communities throughout the District.






Serving Ontario's Premier Cottage Country Since 1981
Mason Cleaning Systems has been protecting Muskoka properties since before the region became one of Canada’s most sought-after cottage destinations. From waterfront retreats on Lake Rosseau to year-round homes in Huntsville, our team delivers professional air duct, dryer vent, and chimney services throughout the District Municipality of Muskoka.
We understand Muskoka properties are different. Whether you’re opening the cottage in May, closing up for winter in October, or maintaining a year-round residence, our services are designed around the unique needs of cottage country living. Our WETT-certified technicians provide the inspections and certifications your insurance company requires for wood-burning appliances.
For cottage owners based in the GTA, we coordinate scheduling around your visits—so you can enjoy your Muskoka time without worrying about maintenance appointments.
The Problem
- Insurance companies require WETT certification for wood-burning appliances—standard cleaning doesn’t satisfy requirements
- Real estate transactions often require WETT inspection before closing on properties with wood heat
- Seasonal cottage use creates inconsistent creosote buildup—months of dormancy followed by heavy weekend burning
- Cottages converted from seasonal to year-round use often have undersized or deteriorating chimney systems
- Many chimney sweeps in Muskoka cannot certify—they can clean, but they can’t provide insurance-recognized documentation
- GTA-based cottage owners need service coordinated around their visits—not everyone can wait around for a return trip
The Mason Solution
David Mason holds both WETT Inspector and WETT Installer certifications—dual credentials that mean thorough inspection combined with practical understanding of installation requirements. When we inspect your Huntsville cottage or home, we’re not just checking boxes. We understand what insurance companies need because we’ve been providing this documentation since 1981.
For Huntsville cottage owners based in Toronto or the GTA, we coordinate service around your visits. Book your WETT inspection before closing the cottage for winter, or schedule spring opening service to ensure everything is safe for the season. When you can only be at your cottage on weekends, you need a service provider who works with your schedule—not against it.

Why Our Equipment Matters for Muskoka Properties
Cottages and seasonal properties face unique air quality challenges. Months of closure allow dust, pollen, and moisture to accumulate in ductwork. When the furnace kicks on after a long winter, those contaminants circulate throughout your property.
We don’t use consumer-grade shop-vacs. Our 5,000 CFM commercial vacuum system with triple filtration captures 99.9% of dust and debris—creating genuine negative pressure that extracts contaminants from your entire duct system. Combined with mechanical agitation, we remove years of buildup in a single service visit.

Why Muskoka Cottages Need Professional Service
If you own a cottage or year-round home with a wood-burning stove, fireplace, or insert in Muskoka, your insurance company likely requires a WETT inspection. And if you’re buying or selling property in cottage country, the real estate transaction may require certification before closing.
The Problem
- Seasonal use creates inconsistent creosote buildup patterns in chimneys
- Cottages converted to year-round use often have undersized or deteriorating chimney systems
- Insurance companies are increasingly strict about wood-burning appliance compliance
- Many service providers can clean chimneys but cannot provide WETT certification
- Extended closures allow moisture, dust, and debris to accumulate in ductwork and vents
The Mason Solution
Our WETT-certified technicians serve Muskoka properties throughout the year. David Mason holds both WETT Inspector and WETT Installer certifications, allowing us to inspect existing installations for insurance compliance, identify safety issues before they become claims, and provide documentation your insurance company will accept.
For Cottage Owners Based in the GTA: We coordinate scheduling around your visits to Muskoka. Book your chimney inspection before closing the cottage for winter, or schedule spring opening service to ensure everything is safe and ready for the season.

FAQ's — Muskoka
Q: Do you charge extra to travel to Muskoka?
A: Our pricing is based on the service plus your location. We travel Highway 11 through Muskoka regularly and build efficient routes. Most Muskoka locations have no additional travel charge. Call us for a quote specific to your property.
Q: Can you coordinate service around my cottage visits?
A: Absolutely. Many of our Muskoka clients are based in the GTA. We schedule around your visits—whether that’s fall closing prep, spring opening service, or a mid-summer maintenance visit.
Q: My cottage has been closed for 6 months. Do I need duct cleaning?
A: Extended closures allow dust, pollen, and moisture to accumulate in ductwork. When the heating system fires up, those contaminants circulate throughout your cottage. We recommend duct cleaning after extended closures, especially if you notice musty odors or increased dust when you arrive.
Q: Why does my insurance company require a WETT inspection?
A: WETT (Wood Energy Technology Transfer) is the certification standard for wood-burning appliances in Ontario. Insurance companies require it because improper installations or deteriorating systems are major fire risks. A WETT inspection verifies your wood stove, fireplace, or insert meets safety standards.
Q: We're converting our cottage to year-round use. Do we need a WETT inspection?
A: Yes. Insurance requirements often change when a seasonal property becomes a primary residence. A WETT inspection ensures your wood-burning system meets the new coverage requirements. We can also assess if your chimney system is sized appropriately for year-round, high-use operation.
Q: How long does a WETT inspection take?
A: A standard WETT inspection takes 60-90 minutes, depending on the complexity of your installation. We inspect the appliance, venting system, clearances to combustibles, and overall condition. You’ll receive a detailed report suitable for insurance submission.
Q: Will duct cleaning make a mess in my cottage?
A: Never. We seal every register and connect our 5,000 CFM vacuum directly to your trunk line through a sealed access point. All debris is captured in our triple filtration system. Your cottage stays cleaner than we found it.
Q: Are you licensed and insured?
A: Yes. We’re fully insured and WSIB registered. David Mason holds WETT Inspector and Installer certifications. We’ve been in business since 1981—your property is in experienced hands.

About The Owner
David Mason, WETT-Certified Inspector & Installer, Serving Northern Ontario Since 1981
At Mason Cleaning Systems Inc., we’re not a franchise or a call center—we’re a family-owned Northern Ontario company built on one purpose: protecting homes and buildings from fire hazards and poor indoor air quality. I’m David Mason, and I founded this company in 1981. For more than 45 years, I’ve worked in attics, crawl spaces, boiler rooms, and rooftops across the Near North. I hold both WETT Inspector and WETT Installer certifications—the credentials your insurance company recognizes for wood-burning appliances. Many companies can sweep a chimney. Very few can legally certify it.
