Attic Insulation Upgrades Across the GTA
Proper attic insulation is one of the most effective ways to reduce energy costs in Southern Ontario’s climate.
We install high-R-value blown-in insulation (fiberglass or cellulose) to:
-
Reduce heat loss in winter and heat gain in summer
-
Make upstairs bedrooms more comfortable
-
Reduce drafts and cold spots
-
Help your furnace and AC work less hard
For many GTA houses, we can top up existing insulation to reach recommended levels, or completely remove and replace if the old material is damaged, contaminated, or moldy.
Safe and Thorough Mold Removal in GTA Attics
Attic mold is common in the GTA due to:
-
Poor ventilation
-
Bathroom fans venting into the attic
-
Roof leaks or ice dams
-
Warm indoor air leaking into a cold attic
Our team provides professional attic mold removal that includes:
-
A thorough attic inspection to find the source of moisture
-
Safe treatment and removal of visible mold on wood surfaces
-
Application of specialized products to help prevent regrowth
-
Recommendations to fix ventilation, insulation, or air leaks so the problem doesn’t come back
We focus on both cleaning the attic and solving the cause.
Attic Ventilation & Air Sealing for GTA Homes
Insulation alone is not enough. Your attic also needs to breathe properly and be sealed against air leaks.
Eco-Therma improves your attic performance by:
-
Checking and clearing soffit vents blocked by insulation or paint
-
Installing or upgrading baffles to maintain airflow from soffits to roof vents
-
Verifying that you have enough roof exhaust vents for the size of your attic
-
Sealing common air leaks (around the attic hatch, pot lights, plumbing penetrations, etc.)
This combination of insulation + ventilation + air sealing helps:
-
Reduce condensation and mold risk
-
Stabilize attic temperature
-
Protect your roof structure and insulation over time
