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.

Why Choose Ottawa Valley Attic Insulation
A valley attic is seldom a tidy builder's attic, and we price it as the house it really is. Farmhouses have board roofs, open wall tops and sawdust between the joists. A town house in Renfrew or Arnprior may hide three layers from three decades. A newer house in Petawawa usually has one thin, even layer that only wants more depth. We climb up, take readings in several bays and look over the wiring, the chimney and the eaves before a single attic insulation number goes on paper.
Your quote names each task with its own price, and the trip to your place is folded into the job instead of tacked on as a fee. Read who we are and how a job runs, or go to the contact page, tell us a little about the house and pick a day.
What We Do In Valley Attics
Each card covers one kind of attic job, from a quick top-up to a full farmhouse, with going rates on every page.
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.
Details and prices
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.
Details and prices
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.
Details and prices
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.
Details and prices
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.
Details and prices
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.
Details and prices
Attic Insulation Cost
Attic insulation cost across the valley usually falls between $1,500 and $4,000 for a full job, and the drive to your home is already part of that. The written quote after a free visit gives you the real figure.
Details and pricesWhat Are The Benefits Of Attic Insulation In A Valley Home?
With proper attic insulation, bedrooms under the roof hold their warmth through a January cold snap instead of chilling as soon as the furnace or stove shuts down.
Propane, oil and electric heat stretch further, because less of the heat you paid for drifts up through the ceiling.
Fewer icicles hang off the eaves, since a cold, well sealed roof lets snow melt evenly in the spring sun.
The wood stove needs fewer logs on a bitter night once the heat stays in the rooms below.
A deep blanket of attic insulation softens wind noise and the rumble of trucks on Highway 17.
In July, the same deep layer keeps bedrooms cooler, so window air conditioners run less.
What Comes With Every Quote In The Valley
These promises hold on every attic insulation job we price, from a small Cobden bungalow to a big stone farmhouse outside Eganville.
- The drive to your property is part of the written price, and no trip fee shows up at the end.
- The attic insulation already in place is measured in several spots and written on the quote as an R-value.
- Every opening that leaks house air into the attic is listed, so you know what gets sealed first.
- Each part of the work has its own line, so you can pick what to do this year and what can wait.
- The finished attic insulation depth and R-value are recorded on your invoice once the work is done.
What Happens During An Attic Insulation Job?
-
It begins with the free visit: readings at several spots, a look at the vents, chimney and wiring, and a written quote you can keep.
-
On install day, runners go down from the entry to the hatch, and whatever sits under the opening gets covered.
-
Up top, the leaks are closed, baffles are stapled in at the eaves and any chimney gets its dam before the attic insulation goes down.
-
The blower on the truck pushes the attic insulation up the hose, and marked depth sticks are set out across the attic so the level is plain to see.
-
We tidy up, show you the finished attic insulation level and put the final R-value on your invoice.

Attic insulation details for Ottawa Valley homes
Travel To Rural Roads Is Already In The Attic Insulation Price
A long drive does not change how we write an attic insulation quote. Homes off Highway 41, Highway 60 and the side roads around Cobden and Eganville get the same kind of written price as a house in town. Getting the truck and the blower to your door is part of the job, not a charge added on the last line.
That makes our numbers easy to set beside any other price you collect. If you want to see how a quote is built, the attic insulation cost page breaks a job into its parts.
Farmhouse Attics Lose Heat Through Open Wall Tops
Plenty of older farmhouses were built with balloon framing, where each stud runs from the foundation clear up to the roof. With no wood plate capping the wall, every stud bay opens straight into the attic. House heat climbs those bays like a chimney and spills out under the roof, even when the attic floor looks well covered.
Before any attic insulation is blown, we cap and seal those wall tops from above. The farmhouse attic insulation page explains how a century house is handled, from board ceilings to old wiring.
Sawdust And Wood Shavings Fall Short In A Cold Attic
Lots of valley farmhouses still have sawdust, shavings or a few inches of tired batts over the ceiling. That fill has packed down for decades and now gives only a small share of the R-value a valley winter calls for. Mice like to nest in it, too.
If the old fill is dry and clean, it can stay as the bottom of new attic insulation. If it is damp, mouldy or full of droppings, it should leave first. Our attic insulation removal service pulls it out through a sealed hose to the truck, so none of it is carried through the house.
Ice Dams Start With Heat Escaping Into The Attic
Snow on a roof should melt from the sun above, not from the house below. When heat seeps into the attic, it warms the upper roof and the snow there turns to water. That water creeps down to the overhang, which sits outside the heated walls, refreezes and stacks up into a ridge of ice. January nights near Petawawa average close to minus 18, so a ridge has weeks to grow.
The fix lives in the attic, not up on the shingles. Our ice dam prevention work seals the leaks, opens the soffit vents and brings the attic insulation up to R-60.
Air Leaks Matter More Than Missing Inches
Attic insulation slows heat, yet air walks right through it. Warm, damp house air rises past pot lights, plumbing vents, wire holes, the hatch and the top of each inside wall. It takes heat with it and leaves moisture on the cold roof boards.
So attic air sealing comes first on our jobs, before a single bale is opened. After the attic floor disappears under new attic insulation, those holes become very hard to find.
Wood Stove Chimneys Need Clear Space In The Attic
Wood heat is common across the valley, and a brick or metal chimney rising through the attic needs breathing room. Natural Resources Canada advises keeping insulation away from chimneys and other combustion vents. We frame a non-combustible dam around the chimney so the new attic insulation keeps its distance.
The gap between chimney and ceiling is then closed with sheet metal and high-heat sealant. It is a small detail, and we check it in every attic with a stove below.
Propane And Oil Heat Make Attic Insulation Pay Back Sooner
Outside the town gas lines, valley homes run on propane, oil, wood or electric heat. Those fuels usually cost more for each unit of heat than natural gas, so every bit of warmth that stays inside is worth more. Sealing the attic and adding attic insulation is one of the plainest ways to stretch a tank.
Ontario's Home Renovation Savings program now covers homes heated with propane and oil, provided they are on the Ontario power grid. Its quick attic stream pays only for work by contractors already named on the program's own list, and that list is no longer taking new names. The other route brings in an energy advisor before and after the job, and then the choice of installer is yours. The attic insulation rebate page has the tiers and the rules, last checked in October 2026, and the attic insulation for propane and oil heated homes page covers fuel savings.
Vermiculite In Older Houses Gets Tested First
Some valley houses from the 1940s and 1950s, early Deep River homes among them, may have vermiculite above the ceiling. It looks like tiny pebbles of grey, gold or brown. Since some vermiculite carries asbestos, nobody should stir it up before a lab says what it is.
When a test is positive, an abatement contractor clears it under Ontario's asbestos rules, and we come back afterwards to install the new attic insulation. The vermiculite attic insulation page lays out that sequence.
Newer Houses Often Stop Short Of R-60
Homes built in the 1990s and 2000s, like a lot of the newer streets in Petawawa, usually shipped with R-30 to R-40 of attic insulation. That met the code of the day, but it sits well under the R-60 that Natural Resources Canada now suggests for an Ontario attic. Near the eaves, where the rafters drop low, the layer is often thinner still.
An attic insulation top-up adds depth over what is there until the whole attic reads R-60. People often pick blown-in cellulose insulation for it, because it packs into tight corners so well.
What Attic Insulation Costs Across The Valley
Most full attic insulation jobs here come to somewhere between $1,500 and $4,000. Plan on $1.25 to $2.75 for each square foot of ceiling when new attic insulation goes over an old layer. Clearing the attic and starting over is closer to $3.00 to $5.75 per square foot, and small jobs begin near $1,200, drive included.
Treat those as Ontario going rates. The number for your house arrives in writing after the free visit.
Frequently Asked Questions
No trip fee is added to an attic insulation quote. The drive is built into the job price on every quote anywhere in our service area.
Natural Resources Canada suggests R-60 for an Ontario attic. Depending on the product, that is somewhere near 16 to 18 inches of cellulose, or more when fiberglass is used.
Yes. A non-combustible dam goes around the chimney so the attic insulation stays clear, and the gap at the ceiling is closed with heat-rated material.
In most cases it is one of the best upgrades a farmhouse can get. Open wall tops and thin old fill waste a great deal of heat, and sealing them first lets the new attic insulation do its job.
A single day of attic insulation work covers most valley houses. When old fill has to come out first, or the farmhouse attic is very large, plan on two.
