North York (Willowdale): thin, patchy insulation and open penetrations — sealed, treated, and blown to R-60

1The Problem

This attic hadn’t failed yet — but it was on its way. Thin, uneven insulation with voids at the eaves, open gaps where ducts and the plumbing stack passed through the ceiling, and darkening on the sheathing at one end where moisture had started collecting.

2What the Inspection Found

The inspection flagged ventilation as the weak point alongside the thin coverage: intake airflow was compromised, and the early staining on the sheathing showed moisture was already lingering. The fix list wrote itself — seal, treat, ventilate, insulate.

3How We Fixed It

A one-day job that heads off a much more expensive one:

• Treated the stained sheathing with our 3-stage cleaning, restoration, and protective sealant
• Air-sealed the ceiling penetrations
• Installed 20 baffle vents to rebuild the intake airflow path
• Upgraded the attic hatch with our insulated hatch solution
• Blew fresh fiberglass over the attic up to R-60
• Returned three weeks later to add a tower roof vent, topping up the exhaust side of the airflow equation

4The Result

For a fraction of what a full gut would cost, this attic went from tired to top-spec — and when the follow-up check suggested the exhaust side could be stronger, we came back and added a tower vent. That’s what a 10-year relationship with your attic contractor looks like.
