An attic insulation top-up keeps your existing fill and blows a fresh layer over it until the attic reads R-60. Our two depth readings record exactly how many inches went on.

Most Newmarket and Aurora attics were filled once, long ago, to a level well under today's. A dry, clean old layer stays put and every inch of it counts toward the target, which is why an attic insulation top-up costs the least of any fix for a chilly second floor.

Attic Insulation Top-Up details

When An Attic Insulation Top-Up Makes Sense

Pick an attic insulation top-up for a layer that is in good shape but simply too thin. Clues include bedrooms a few degrees cooler than the main floor, a furnace that hardly rests in January, and icicles that return to the same stretch of gutter each winter.

The hatch tells you a lot too. When the joist tops poke up through the fill, the attic holds under roughly ten inches, and an attic insulation top-up will make a real difference.

How We Measure Before And After

The ruler goes down to the drywall at marked points from one end of the attic to the other, and each reading is copied onto your quote. Thin trails near the hatch and along old crawl paths are noted, since they take the most new fill.

Once the attic insulation top-up is finished, the ruler goes back to those same points and the new depths are written beside the old ones. Your invoice shows both columns and the R-value each works out to for the product used.

What The Attic Insulation Top-Up Includes

An attic insulation top-up from us always begins with attic air sealing at pot lights, pipes and wire holes. Baffles keep each soffit open, the hatch gets a gasket and foam board, and the new fill is blown level from eave to peak.

Most of our top-ups use blown-in cellulose insulation, which knits into older cellulose and settles into a dense blanket. Fiberglass is used where the attic suits it better.

Attic Insulation Top-Up Price

Expect an attic insulation top-up to run $1.25 to $2.50 per square foot of the floor up there, with a floor of roughly $1,000 for small jobs. The missing inches and the crawl room set where your price falls. Our attic insulation cost page lays out the rest.

Jobs That Often Share The Same Visit

Sealing, the hatch and a top-up tend to share one install day, which spares you a second visit.

  1. Grey blown cellulose spread across an attic floor, with light coming through the soffit vents

    Cellulose Insulation

    Cellulose insulation starts life as newsprint and cardboard, shredded and treated so it resists fire and pests, and we blow it across the attic floor as loose fill. Because it tucks in around wiring, nails and truss webs, cellulose insulation is the material we pick most often for older attics.

  2. Thick white blown-in fiberglass across an attic, lit by a gable window

    Blown-In Fiberglass Attic Insulation

    Blown-in fiberglass insulation arrives as fluffy spun glass that the hose lays down in a soft, even blanket. It will not soak up water, puts very little weight on the ceiling and holds its depth for years.

  3. Vacuum hose nozzle lifting old cellulose insulation out of a joist bay

    Attic Insulation Removal And Replacement

    Attic insulation removal clears out fill that is damp, mouldy, fouled by mice or squirrels, or crushed past saving. With the joists bare and the ceiling sealed, new attic insulation is blown back in to full depth.

  4. White insulation pouring from a blowing hose onto an attic floor under the rafters

    Attic Air Sealing

    Attic air sealing shuts the small openings where heated house air pours up into the attic, with spray foam, caulk and fitted covers. We do it before any new attic insulation goes down, since insulation slows heat yet lets moving air straight through.

  5. Attic hatch opening framed by a raised wooden dam in deep white loose-fill insulation

    Attic Hatch Insulation

    Attic hatch insulation turns a thin, drafty access lid into part of the insulated ceiling. We gasket the frame and glue a thick stack of foam board onto the lid, so the hatch holds heat like the attic around it.

  6. Dark water stain on attic roof boards above damp, matted cellulose insulation

    Ice Dam Prevention

    Ice dam prevention aims to hold the roof deck at outdoor temperature, so high snow stays frozen instead of melting and refreezing at the eaves. In practice that means sealing the ceiling, keeping soffit air moving and bringing the attic insulation to full depth.

  7. Old, thin cellulose insulation lying on an attic floor under bare roof framing

    Attic Insulation Rebate

    A Newmarket owner whose thin attic is brought up to R-50 may qualify for an attic insulation rebate under Home Renovation Savings, the province-wide program run jointly by Save on Energy and Enbridge Gas. The thinner the attic was, the larger the attic insulation rebate.

  8. Pink fiberglass batts laid between joists across a wide, lit attic

    Attic Insulation Cost

    Four things drive attic insulation cost in Newmarket: how big the attic is, which material you pick, how many inches are already up there, and whether a clear-out comes first. Most homes pay between $1,500 and $3,500.
