Attic Insulation Top-Up
Improve home comfort and energy efficiency with professional attic insulation upgrades and top-ups.
What the attic is telling you
Signs you may need this
Weather usually gets blamed first. Escaping attic heat is often the real source.
Built for the attic in front of us
Materials and options
Blown-in fiberglass
Lightweight loose fill that suits open attic areas and irregular framing.
Blown-in cellulose
Loose fill that follows attic geometry and helps limit small coverage gaps.
Batts
Fitted sections used where the attic layout makes a precise fit practical.
Why coverage matters more than depth alone
Heat takes the easiest path out. That means the thinnest part of the attic floor carries far more of the loss than its share of the surface, so a few bare patches undo a lot of average depth. Coverage is checked at several points on the day of the work, and the target is set from what is actually there rather than from a standard package.
Is this the right call for your home?
When it applies
- The existing insulation is dry and in good condition
- The measured depth is below the target for the assembly
- Air leakage paths have been sealed, or will be sealed first
When something else comes first
- The existing material is wet, compacted or contaminated, so removal comes first
- There is fungal growth on the wood, which is remediation before insulation
- A roof leak is still active, which has to be repaired before anything is added
This is not a matter of adding bags on top of whatever is up there. If what is already in the attic has failed, adding to it hides the problem instead of correcting it, and you pay twice.
How the work runs
Our process
The remote quote
Depth, coverage, condition of the existing material and the state of the ventilation path, worked out from your address and attic size.
Air sealing where required
Accessible penetrations, the hatch and top plates, before any new material goes in.
Baffles and ventilation check
Soffit intake is kept clear so the attic can still breathe once the depth increases.
Installation to the target depth
Even coverage across the attic floor, including the areas that are hard to reach.
Depth verification and cleanup
Depth confirmed at several points, and the access path left clean.

Can you add insulation on top of what is already there?
Often yes, if the existing material is dry and in good condition. If it is compacted, wet or contaminated, it comes out first.
How much insulation does an Ontario attic need?
The target is set from what is actually in your attic, not from a standard package.
Do you seal air leaks before adding insulation?
Where leakage is found, yes. Adding depth over an unsealed ceiling leaves the air movement in place, and air movement carries more heat than most homeowners expect.
How long does a top-up take?
Most residential attics are completed in a single visit. The assessment establishes the scope before the work is scheduled.
