Attic Insulation Top-Up In Bradford, Ontario

When An Attic Insulation Top-Up Is Enough

A top-up suits any attic whose current layer is dry, pest-free and just too shallow. That fits most Bradford houses put up over the last few decades.

Ruler readings are taken in at least six places across the floor. When they come in well below R-60, an attic insulation top-up gives the house the most comfort for each dollar spent. If the old layer is damp, mouldy or full of droppings, attic insulation removal has to happen first.

Sealing Comes Before Any Attic Insulation Top-Up

New fill spread over a ceiling full of holes still lets heated air drift up into the roof space. That is why, ahead of any attic insulation top-up, we plug the gaps at recessed lights, fan boxes, wire holes, plumbing vents and the top plates of inside partitions.

The hatch gets a gasket and a rigid foam back. That prep takes about an hour on a typical house, and it makes every inch of the attic insulation top-up count. See the attic air sealing page for the full list of what gets sealed.

Baffles Keep The Attic Insulation Top-Up Off The Vents

Adding depth raises the attic floor toward the roof deck at the eaves. Without baffles, the new layer can slide into the soffits and choke off the outside air the attic depends on.

A baffle goes into every rafter bay along both long walls before the hose arrives. Each baffle holds a clear lane for air between the soffit and the attic, so the attic insulation top-up can run right out to the edge.

Attic Insulation Top-Up Prices

Bradford top-up pricing sits at $1.40 to $2.40 a square foot, with baffles built into that rate. For an average subdivision attic, an attic insulation top-up comes to roughly $1,400 to $3,000. Your quote spells out where the depth starts, the R-value where it ends and the total.
