Attic Insulation Top-Up To R-60
An attic insulation top-up blows fresh cellulose over the layer already in place and lifts the attic to R-60. For a chilly top floor in an older Orléans house, it is the quickest fix there is.

Ontario attic rebates up to $1,250 may applyAttic air sealing plugs the openings between your living space and the attic above. Heated air rises out through pot lights, wire holes, vent stacks and the hatch, carrying moisture along with it.
We seal those gaps with caulk, foam and rigid covers before any insulation goes in. Attic air sealing is a line on every quote we write.
Attic Air Sealing Details
Insulation Alone Does Not Stop Air Leaks
Fibreglass and loose fill slow heat, but air can still move through them. A leaking ceiling under deep insulation still loses heat and still sends damp air into the attic.
So attic air sealing always happens first, and every inch of insulation laid over it then works as it should.
Attic Air Sealing Prevents Frost On The Roof Boards
Through a long Ottawa cold snap, moist air that slips into the attic turns to frost under the roof deck. A thaw melts it and it drips into the insulation, and a few winters of that can stain the wood and start mould.
Sealing the ceiling cuts off the moisture at its source. If the damage has already started, see our page on wet attic insulation.
Where We Seal In A Typical Orléans Attic
The usual spots are the top plates of interior walls, wires and pipes that pass through the ceiling, bathroom fan housings, pot lights, and the chimney or furnace flue chase. In townhomes, the joint along the party wall gets extra attention.
Attic air sealing ends at the hatch: we add a foam gasket around it and glue rigid insulation to its lid, so it shuts tight.
Attic Air Sealing Pricing
Attic air sealing is usually priced per job. At Ontario market rates it often adds about $400 to $1,500, depending on how many openings the ceiling has and how easy the attic is to move around in.

Old Attic Insulation Removal
Attic insulation removal pulls out old fill that is flattened, dirty or damaged, so the attic can be sealed and refilled properly. It leaves through a sealed vacuum hose and goes away in bags.

Ice Dam Prevention
Ice dams start when warmth leaking out of the house softens roof snow from underneath and the water freezes again at the cold overhang. Ice dams then hold back more meltwater, which can creep under the shingles and stain the ceiling.

Wet And Mouldy Insulation
Wet attic insulation holds little heat, and left damp it can feed mould on the roof boards. We find out where the water came from, take out the damaged material, and reinsulate once the wood is dry.

Vermiculite Insulation
Vermiculite insulation is a light, pebbly loose fill in silver-gold to grey-brown. Some vermiculite insulation sold in Canada before 1990, including the Zonolite brand, came from a mine with natural asbestos in it. Not all of it contains asbestos, and nobody can tell by looking.
