1. Check Your Attic Insulation First
Why it matters: Heat rises — and if your attic isn’t properly insulated, you’re losing warmth (and money) through your roof.
What to look for:
Is your attic insulation depth at least R-50 (typical for Ontario)?
Are there any bare patches, moisture spots, or rodent nests?
Do you feel a temperature difference between rooms on the top floor?
Enerliv Tip: Blown-in or batt insulation can be added to boost performance. For extra protection, consider spray foam along the attic floor or roof deck.
2. Inspect Exterior Walls for Cold Spots
Why it matters: Wall cavities make up the majority of your home’s thermal envelope. Poor wall insulation = poor year-round performance.
What to look for:
Cold or drafty spots on exterior walls
Discoloration or mold near baseboards or outlets
Walls that feel cold to the touch in winter
Enerliv Tip: For renovations or new builds, spray foam or batt & poly ensures maximum thermal protection and an airtight seal.
3. Evaluate Basement and Crawlspace Insulation
Why it matters: Basements are a major source of energy loss — and they’re often overlooked.
What to look for:
Cold floors above basement or crawlspace
Bare or improperly insulated foundation walls
Signs of condensation or dampness
Enerliv Tip: Insulating the rim joists with spray foam and walls with rigid foam or batt can make a huge difference in comfort.
4. Don’t Overlook the Garage and Bonus Rooms
Why it matters: Attached garages and over-garage rooms often lack proper insulation — making them difficult to heat or cool.
What to look for:
Is the garage ceiling insulated?
Do temperature swings affect the room above?
Are you storing temperature-sensitive materials?
Enerliv Tip: Use closed-cell spray foam for high-performance insulation in walls and ceilings.
5. Check Air Sealing Around Windows, Doors & Vents
Why it matters: Even great insulation can underperform if warm air is escaping through gaps and cracks.
What to look for:
Drafts near window and door frames
Gaps around pipes, light switches, and vents
Old or deteriorated caulking and weatherstripping
Enerliv Tip: Pair insulation upgrades with air sealing for the best results — especially when applying spray foam.
6. Ensure Fireproofing Meets Code Requirements
Why it matters: Fire-resistant insulation materials are critical for new builds, basement apartments, and commercial spaces.
What to look for:
Are your spray foam insulation layers covered with ignition barriers?
Have you applied fireproofing sprays or coatings on structural elements?
Are any code upgrades required for occupancy?
Enerliv Tip: We provide spray-applied fireproofing that meets Ontario’s building code requirements for both wood and steel structures.
7. Ask About Ontario Rebates & Incentives
Why it matters: Insulation upgrades can qualify for rebates through Enbridge, Canada Greener Homes, and other local programs.
What to look for:
Do you have a recent home energy audit?
Are you planning renovations that could trigger eligibility?
Have you applied for available funding?
Enerliv Tip: We’ll help you navigate rebate programs and maximize your return on energy-saving upgrades.
