Attic insulation replacement is a clear-out and a refill: the old layer is vacuumed away, the attic is cleaned, and new loose fill goes in to R-60. It is the answer when the existing material is soaked, mouldy, fouled by animals or crushed flat.

Plenty of attics can skip the clear-out. Sound, dry fill can simply be topped up for far less money. The photo check settles which camp your attic is in before any figure is written.

Signs That Call For Attic Insulation Replacement

Stains on the roof boards, insulation that is matted or crusty, droppings, nesting trails and a strong smell all point to replacement. So does an old roof leak that soaked one part of the attic. Burying damaged material under a new layer hides the problem without removing it.

If the attic has gravel-like, grey-brown or gold insulation, it may be vermiculite. Vermiculite can contain asbestos and should not be disturbed. It has to be tested first, and if it contains asbestos, removal is a job for an asbestos abatement contractor under Ontario rules. Attic insulation replacement can follow once the attic has been cleared.

How Attic Insulation Replacement Is Done

A wide suction hose runs from the vacuum unit in the driveway up through the house, so old fill rides straight out to bags outdoors. Drop cloths cover the route to the hatch before the motor starts. With the bays empty, the joists are vacuumed bare and the sheathing is checked for rot or old leaks.

With the attic bare, it is the easiest time to seal the ceiling properly. Every gap is reachable. Our attic air sealing page explains which openings matter most.

The Refill After Attic Insulation Replacement

Once the deck is clean and sealed, eave chutes go in and fresh cellulose or fiberglass is blown to R-60. Your attic insulation replacement quote breaks out the clear-out, the sealing and the refill, one line each.

Attic Insulation Replacement Price

Ontario attic insulation replacement commonly runs $3 to $5.50 a square foot of ceiling area for the clear-out, cleaning, sealing and refill together. The clear-out by itself is commonly $1.50 to $3.50 a square foot. Cramped access and heavy fouling raise it.

Work That Often Goes With This Job

Most Kanata attics get two or three of these done in the same visit, which saves a second trip.

Blown-In Fiberglass Insulation

Blown-in fiberglass insulation is loose glass fibre blown through a hose into the attic, where it builds a light, even layer over the ceiling. It does not absorb water and it does not settle much, which makes it a steady choice for an attic that will be left alone for decades.

Attic Air Sealing

Attic air sealing plugs the holes in your top-floor ceiling where heated indoor air sneaks up under the roof. Loose fill slows heat soaking through drywall, yet air pours through an open hole as if the fill were not there.

Attic Ventilation And Baffles

Attic ventilation lets outside air enter at the soffits and leave near the peak, which keeps the attic close to the outdoor temperature and carries moisture away. A cold, dry attic means snow melts less from below, the roof boards stay sound and the insulation stays dry.

Bonus Room Insulation

Bonus room insulation fixes the room that sits over an attached garage and never feels like the rest of the house. That room has a cold garage under its floor, short knee walls with attic space behind them and a sloped ceiling under the roof.
