Attic Insulation Top-Up
An attic insulation top-up lays new loose fill over the layer you have now until the whole attic reads R-60. When the existing layer is dry and sound, it is the fastest way to warm the top floor.

Attic Air Sealing In The Ottawa Valley, Ontario
Ontario attic rebates up to $1,250 may applyAttic air sealing closes the holes in your ceiling where warm house air drifts up into the attic. It always comes before new fill, since insulation slows heat but lets moving air pass.
The work goes after openings you never see from the rooms below: pot light housings, plumbing vents, wire holes, bathroom fan boxes, the tops of inside walls and the edges of the hatch. Each one lets warm, damp air climb into a cold space.
Attic Air Sealing details
Attic Air Sealing For A Cold Valley Winter
Warm air reaching a cold attic carries water vapour. On a minus 30 night, that vapour turns to frost on the roof nails and boards, and it drips once the weather softens. The same leaks warm the roof and feed ice at the eaves.
Attic air sealing cuts off both at the source. It also lets the attic insulation above it work as it should, because the heat stays under the ceiling.
What Attic Air Sealing Covers
Small holes and cracks get spray foam, larger openings get rigid foam board, and chimneys and flues get sheet metal with high-heat sealant. Older pot lights get covers so fill can sit over them safely. The hatch gets weatherstripping and an insulated lid.
In farmhouses, the job also means capping the open wall tops left by balloon framing. The farmhouse attic insulation page explains that part.
Attic Air Sealing Before The Ice Builds
Most ice dams begin with house air leaking into the attic. Attic air sealing is the first step of our ice dam prevention work, followed by clear soffit vents and a deep layer of fill.
Attic Air Sealing Price
Sealing is generally priced by the job, and most valley houses land between $500 and $1,500. For rough planning, use $0.50 to $1.25 for each square foot of ceiling. Farmhouses with open wall tops sit toward the top of that range.

Jobs That Pair Well With This One
Sealing, baffles and new fill usually travel together, and one drive out covers all of them.
Blown-In Cellulose Insulation
Cellulose insulation is blown loose over the attic floor, where it drapes around wires, braces and low eaves that a batt cannot reach. It suits the uneven, crowded attics of older valley houses.

Farmhouse Attic Insulation
Farmhouse attic insulation begins by sealing the open wall tops and board ceilings that let heat pour into an old attic, then lays deep loose fill on top. It is the job old valley farmhouses need most.

Attic Insulation Removal
Attic insulation removal clears out old material that is wet, mouldy, crushed flat or soiled by animals, so new fill can go onto a clean attic floor. Blowing over a ruined layer only hides the trouble.

Vermiculite Attic Insulation
Vermiculite insulation needs a lab test before anyone disturbs it, because some of it contains asbestos. Testing comes first, clean-out second and new attic insulation last.

Ice Dam Prevention
Ice dam prevention keeps the roof cold from underneath by sealing air leaks, opening the soffit vents and adding attic insulation to R-60. Stop the melt in the attic and the ice stops building at the edge.

Attic Insulation For Propane And Oil Heated Homes
Air sealing and attic insulation cut how much propane or oil a rural house burns each winter, because less heat escapes upward. The savings count for more when the fuel costs more.

Attic Insulation Rebate
Valley homeowners who lift a thin attic to R-50 can claim an attic insulation rebate under the province's Home Renovation Savings program, and $1,250 is the top amount. Propane, oil, wood, electric and gas heated houses can all apply.
