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.

Ice Dam Prevention In The Ottawa Valley, Ontario
Ontario attic rebates up to $1,250 may applyIce 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.
Picture the roof in February. Heat sneaking into the attic warms the shingles high up, snow there turns to water, and the water slides down to the overhang. Out past the heated walls, the overhang is cold, so the water locks up as ice. Week after week the ridge thickens until melt water pools behind it and finds its way under the shingles.

Why Ice Dam Prevention Matters In The Upper Valley
Upper valley winters are long, with January nights near Petawawa averaging close to minus 18 and a record low past minus 40. Snow stays on roofs for months, so any heat leaking upward has a long season to melt it.
Raking the roof and chipping ice deal with what you see. Ice dam prevention in the attic deals with what causes it, which is why ice dam prevention starts up the ladder.
The Three Parts Of Ice Dam Prevention
Part one is attic air sealing, which keeps warm air off the roof boards. Part two is airflow: baffles at the eaves hold the soffit vents open so cold outside air can sweep under the roof. Part three is a deep, even layer of fill that slows heat through the ceiling.
Each part needs the other two. Ice dam prevention that skips one usually leaves the job half done.
Ice Dam Prevention Around Fans And Chimneys
A bathroom fan that dumps into the attic instead of outdoors puts warm, wet air right under the roof. We check where each fan exhausts and flag any that need a duct to the outside. Chimneys and stove pipes get a non-combustible dam and closed gaps.
Ice Dam Prevention Price
Most ice dam prevention jobs combine sealing, baffles and an attic insulation top-up. In Ontario, that bundle usually comes to $1.75 to $3.50 for each square foot of ceiling. Each part is listed separately so you can see where the money goes.

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.
Details and prices
Attic Air Sealing
Attic 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.

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.
Details and prices
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.
