An attic insulation top-up lays fresh blown fill over whatever clean layer is already there, lifting a thin attic to about R-60 in a single visit. It fits any attic whose existing insulation is still dry and free of droppings.

A large share of Vaughan's houses went up between the mid-1990s and the mid-2000s with attics finished near R-31. Rooms upstairs run cool in January and the furnace works longer to keep up. Closing that shortfall takes one morning.

Attic Insulation Top-Up details

When An Attic Insulation Top-Up Makes Sense

Choose an attic insulation top-up when the layer up there has no droppings, no water marks and no sour smell. Our free walk-through checks every bay and photographs it, so you can see the condition for yourself.

Where only part of the attic is fouled, the quote handles it in two steps. Those bays come out first through our rodent damaged attic insulation removal service, and then the attic insulation top-up runs across the whole floor.

Gaps Get Sealed Ahead Of The Attic Insulation Top-Up

Fill stops heat from conducting, yet house air moving up through a gap carries heat straight past it. Pot lights, wire holes and plumbing vents are the usual culprits in Vaughan attics.

That is why the sealing happens first, while the joists are still visible. Attic air sealing plus an attic insulation top-up outperforms either one on its own, and we do both on the same day.

How Deep The New Layer Goes

The final height depends on the material. Blown cellulose reaches R-60 at around 16 to 17 inches in total, and blown fiberglass at nearly 20. Cardboard rulers stapled to the trusses show the line, and the hose keeps going until every ruler is buried to it.

Attic Insulation Top-Up Pricing

Budget $1.25 to $2.50 a square foot for an attic insulation top-up. For 1,200 square feet of attic, plan on roughly $1,500 to $3,000, with sealing and the hatch listed on the same quote.

Related Attic Services

Most Vaughan attics end up needing two or three of these together.

  1. Tan fiberglass batts between attic joists on each side of a plywood walkway leading to a gable vent

    Blown-In Fiberglass Insulation

    Blown-in fiberglass insulation is fluffy glass fibre carried by air down a hose until it drifts into every bay and corner. It weighs little, never soaks up water and brings a thin attic up to current levels fast.

  2. Thick grey-brown blown cellulose covering an attic floor beneath dark roof boards

    Blown-In Cellulose Insulation

    Blown-in cellulose insulation is shredded recycled paper treated with borates against fire, mould and insects. Blown to the right density, this attic insulation tucks around wires and truss plates and forms a heavy, quiet layer.

  3. Worker in a white protective suit and respirator stuffing old pink batts into a black bag in an attic

    Rodent Damaged Attic Insulation Removal

    When mice, squirrels or raccoons have nested in the attic, we take out the fouled attic insulation, disinfect the bare joists and close the holes they used from inside. New insulation is installed only after that.

  4. Worker in a dust mask and gloves pressing a pink batt into a wall stud bay beside a window frame

    Attic Air Sealing

    Attic air sealing blocks the openings between the rooms below and the attic, so heated air stays in the house and the fill above can do its job. We seal pot lights, wire holes, plumbing vents and wall tops from the attic side.

  5. Pink fiberglass batts laid around a framed attic hatch opening in a finished attic floor

    Attic Hatch Insulation

    Attic hatch insulation seals and insulates the access panel in your ceiling. An unsealed hatch can let out more heat than a large stretch of insulated ceiling around it.

  6. Worker standing on a scaffold pressing a mineral wool batt between ceiling joists

    Cathedral Ceiling Insulation

    Cathedral ceiling insulation packs the thin rafter cavity above a sloped ceiling, where there is no attic floor to work on. The method depends on how deep the rafters are, how the roof vents and how we can get inside.

  7. White loose-fill insulation spread across an attic floor up to the bottom of the roof trusses

    Attic Insulation Rebate

    Through its Home Renovation Savings program, Ontario's gas and electricity utilities have offered an attic insulation rebate topping out at $1,250 for an attic finished at R-50. Here is what the program's own pages said when we read them, so you can plan with real figures.

  8. Pink batts between joists across a whole attic, with a round window in the gable wall

    Attic Insulation Cost

    Attic insulation cost for a detached Vaughan house usually falls between $1,500 and $5,000. Job type, floor area and the state of the old fill push yours up or down that scale.
