Water Damage Ceiling Repair Ajax LLC removes and replaces water-damaged ceiling and attic insulation throughout Ajax. Saturated insulation loses up to 40% of R-value within 48 hours and becomes a mould breeding ground.
What Damage Does Water Cause to Ceiling Insulation?
5 types of insulation damage occur when water reaches ceiling and attic cavities in Ajax homes.
- R-value collapse: Wet fibreglass batts compress and lose 40% thermal efficiency, increasing heating costs by $200 to $600 CAD per winter
- Cellulose clumping and settling: Blown-in cellulose absorbs 5 to 10 times its weight in water, compacting into dense mats
- Mould growth on organic fibres: Cellulose and kraft-faced fibreglass support mould colonization within 24 to 48 hours
- Added dead weight on ceiling joists: Waterlogged insulation adds 15 to 40 kg per square metre, stressing ceiling framing
- Vapour barrier breach: Water degrades polyethylene vapour barriers, allowing ongoing moisture migration
How Much Does Ceiling Insulation Replacement Cost in Ajax?
$1,500 to $6,000 CAD for ceiling insulation water damage replacement in Ajax.
Ontario Building Code requires minimum R-50 for attic insulation in new construction. Water Damage Ceiling Repair Ajax LLC installs to R-50 or higher on all Ajax replacements.
| Insulation Type | Cost per sq m (CAD) | Full Attic (80 sq m) |
|---|---|---|
| Fibreglass batt (R-32) | $12 to $18 | $960 to $1,440 |
| Blown-in fibreglass (R-50) | $15 to $22 | $1,200 to $1,760 |
| Blown-in cellulose (R-50) | $10 to $16 | $800 to $1,280 |
| Spray foam closed-cell (R-30) | $35 to $55 | $2,800 to $4,400 |
| Wet insulation removal (add-on) | $5 to $10 | $400 to $800 |
Is Wet Ceiling Insulation Salvageable or Does It Need Full Replacement?
No -- saturated insulation requires full replacement in 85% of cases. Fibreglass batts technically dry but lose structural loft permanently. Cellulose insulation clumps irreversibly when wet. Spray foam retains moisture inside closed cells, degrading from within.
The only salvageable scenario involves fibreglass batts with less than 24 hours of water exposure and no mould growth. Water Damage Ceiling Repair Ajax LLC uses moisture meters to test insulation at multiple depths. Replacement costs less than the energy loss from degraded insulation over a single Ajax winter season.
