ECO-THERMA
Insulation and Mold Removal in Markham
Comfort, Energy Efficiency & Cleaner Air for Markham Homes
The community of Markham is known for its modern multi-level homes, family neighbourhoods, and rapidly growing developments 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, one issue remains very common across Markham properties:
-
heat loss through the attic,
-
uneven temperatures between floors,
-
excessive attic humidity,
-
and mold growth in the roof deck.
Eco-Therma provides professional attic insulation, mold remediation, and attic ventilation optimisation designed specifically for the climate and home structures found in Markham.

Attic Challenges in Markham
Markham experiences cold winters and hot humid summers. Without proper attic protection, this climate can lead to:
-
High heating and cooling bills
-
Drafty rooms in winter and overheated upstairs bedrooms in summer
-
Condensation inside the attic
-
Mold on roof sheathing and rafters
Our goal is to solve these issues at the root, not just temporarily.
Advanced Attic Insulation for Markham Homes
We install high-R-value blown-in insulation (fiberglass or cellulose) to provide immediate energy savings and year-round comfort.
Homeowners in Markham benefit from:
-
Lower heating and cooling costs (up to 25% reduction for many clients)
-
More consistent temperatures across floors
-
Less stress on HVAC equipment
-
Longer roof lifespan through temperature and moisture control
Before adding insulation, we can also:
-
Seal attic air leaks
-
Insulate and weather-seal the attic hatch
-
Verify ventilation to prevent moisture buildup
Professional Mold Removal in Markham Attics
In Markham neighbourhoods — especially Unionville, Cornell, Angus Glen and Berczy Village — attic mold often results from:
-
Poor air circulation
-
Insufficient insulation causing moisture and ice damming
-
Bathroom fans venting into the attic instead of outdoors
Eco-Therma provides:
-
A detailed moisture and ventilation inspection
-
Safe and complete mold removal using professional-grade products
-
Preventative treatment to stop the mold from returning
We don’t just remove mold — we eliminate the cause so it doesn’t come back.
Attic Ventilation & Airflow Optimization
Proper ventilation is critical to prevent attic humidity, protect insulation, and ensure the roof structure remains healthy.
We optimize airflow in Markham attics by:
-
Clearing blocked soffit vents
-
Installing or upgrading baffles/deflectors to maintain steady air intake
-
Checking roof vents / ridge vents / low-profile vents
-
Fixing bathroom and kitchen fans that vent incorrectly into the attic
Good airflow =
✔ dry attic,
✔ longer-lasting insulation,
✔ zero mold in the future.
Our numbers speak for themselves.
