2. Add attic insulation

Adding attic insulation is a smart way to cut down on heat loss in Nova Scotia's multi-unit rental properties. Since heat naturally rises, a poorly insulated attic can allow up to 40% of your heating costs to escape through the roof. This not only wastes energy but also increases operating expenses and eats into rental profits.

Nova Scotia's building code requires R-50 insulation in attics, but many older properties don’t meet this standard. Upgrading insulation creates a thermal barrier that keeps heat inside during the cold months, lowering heating demands and reducing utility bills.

Cost-effectiveness (initial investment vs. savings)

This upgrade is a win for both short-term savings and long-term returns. Bringing attic insulation up to R-50 using blown-in fibreglass or cellulose typically costs $2.50–$4.00 per square foot. For a 1,200-square-foot unit, the total cost, including materials and professional installation, ranges from $3,600 to $4,800.
