About us

Less heat loss, lower Hydro bills.

A poorly insulated attic can account for up to 30% of your heat loss
in winter — and it shows on your Hydro bill. Eco Isolation fixes that
problem cleanly, quickly, and with the government grant included.

We’re exclusive residential insulation specialists in Montreal.
Every evaluation is free, every installation is done in 1 day,
and we guide you through your Rénoclimat file from start to finish.

Our services

Three signs. One solution.

Poor Insulation

When your home is poorly insulated, energy escapes through the roof, walls, and gaps. You pay more to heat and cool your home, while comfort keeps decreasing.

Moisture and Mold

Poor insulation can allow moisture to enter and create mold. This can damage your home and affect your daily well-being.

Compressed Insulation

When insulation loses its thickness, your home loses efficiency. Some rooms become cold, uncomfortable, and more expensive to heat.

OUR WORK

Before. After. The difference speaks for itself.

Every attic we insulate means a warmer home, a lower Hydro bill, and a satisfied homeowner. Here are some of our recent projects in Montreal and Greater Montreal.

Your poorly insulated attic is costing you money. We fix that.

Free in-home evaluation. Up to $1,500 in subsidies. Installation in 1 day.
