Attic Insulation in Markham
Ventilation, mold remediation and insulation removal, quoted remotely from your address.
Comfort, Energy Efficiency & Cleaner Air for Markham Homes
is known for its modern multi-level homes, family neighbourhoods, and
in areas such as Unionville, Cornell, Wismer, Angus Glen, Greensborough, Berczy Village, Thornhill (Markham side), Box Grove, and more.
But whether the home is newly built or from the 1990s-2000s era,
attic insulation, mold remediation, and attic ventilation optimisation
designed specifically for the climate and home structures found in Markham.
Markham experiences cold winters and hot humid summers. Without proper attic protection, this climate can lead to:
- Drafty rooms in winter and overheated upstairs bedrooms in summer
Our goal is to solve these issues at the root, not just temporarily.
We install high-R-value blown-in insulation (fiberglass or cellulose) to provide immediate energy savings and year-round comfort.
- Lower heating and cooling demand
- Longer roof lifespan through temperature and moisture control
- Verify ventilation to prevent moisture buildup
In Markham neighbourhoods — especially Unionville, Cornell, Angus Glen and Berczy Village — attic mold often results from:
- Insufficient insulation causing moisture and ice damming
- Bathroom fans venting into the attic instead of outdoors
- A detailed moisture and ventilation inspection
- Safe and complete mold removal using professional-grade products
- Preventative treatment to stop the mold from returning

Eco-Therma
Usually replies the same day
Do you serve Markham?
Yes. Eco-Therma serves Markham, and works across Toronto, the GTA and the surrounding areas. The same crews and the same methods apply everywhere in that area.
How do you estimate a job in Markham without visiting?
From the property address and the approximate size of the attic. That lets us measure the roof and attic footprint remotely and send a real range back — that is the Fast Remote Quote, and it needs no attic access and no visit to book.
How far does the service area go past Markham?
Further than the list on the site suggests. Markham is covered, and so is the surrounding area — if you are not sure whether your address qualifies, calling is faster than guessing.
What does a Fast Remote Quote look at?
Insulation depth and condition, air leakage paths through the ceiling, soffit intake and roof exhaust, and any sign of moisture or contamination. The Eco-Therma recommendation follows what is found, not a standard package.
What if the attic needs more than insulation?
Eco-Therma says so. Removal, mold remediation or decontamination sometimes has to happen before new insulation goes in, otherwise the new material ends up in the same condition as the old.
