Rebate programs this work can qualify for
Why Your Attic Matters Most
Warm air rises, so the attic is where most homes lose the most heat. Many Lower Mainland homes built in the 1970s to 1990s still have R-12 to R-20 left in the attic, far below the R-50 we recommend today.
Lower heating bills
Warmer rooms upstairs
Fewer ice dams and less attic condensation
What an Attic Upgrade Does for Your Home
Keeps heat where you pay for it
A deeper, even layer of insulation slows heat loss through the ceiling in winter and keeps upstairs rooms cooler in summer.
Evens out room temperatures
Cold bedrooms over garages and hot top floors are usually attic problems.
Protects the attic from moisture
Air sealing and baffles keep warm, damp indoor air out of the attic – see our guide to attic condensation in winter.
Pays part of itself back
The BC Hydro attic rebate covers $0.02 per square foot for every R-value point you add.
Attic Insulation Options
Most attics we work on get blown-in fibreglass, because it fills around joists, wiring and corners in one continuous layer.
Insulation Options
Blown-in fibreglass
Blown-in insulation is our standard for attic top-ups and new installs, including Owens Corning ProPink.
Fibreglass batts
Batt insulation suits open joist bays, attic knee walls and areas we can reach easily.
Air sealing
We seal around the attic hatch, pot lights, plumbing stacks and wire penetrations before any insulation goes in.
Baffles and ventilation
Rafter baffles keep soffit vents clear so the attic can breathe.
How We Insulate an Attic, Step by Step
Inspect
Measure the existing depth and R-value, check for moisture, mould, rodent damage and vermiculite.
Protect
Cover floors and the path to the attic hatch.
Prepare
Remove damaged insulation if needed (insulation removal), install baffles, seal air leaks.
Insulate
Blow in fibreglass to the agreed depth and set depth rulers so you can see the result.
Finish
Insulate and weatherstrip the hatch, clean up, and give you a rebate-ready invoice

Bonus of up to $2,000 when you complete more than one upgrade

Frequently Asked Questions
What R-value should my attic have in the Lower Mainland?
We recommend at least R-50 in Lower Mainland attics, which is about 16 to 20 inches of blown-in fibreglass depending on the product. Many homes built before the 2000s have R-12 to R-20 left because the original insulation has settled. Topping up to R-50 also qualifies you for the BC Hydro attic rebate.
How much does attic insulation cost?
A blown-in attic top-up typically costs about $1.50 to $2.45 per square foot in the Lower Mainland, so roughly $1,500 to $2,450 for a 1,000 sq ft attic before rebates. Removal of old insulation, tight access and extra baffles add to the price. We give a fixed written quote after a free assessment.
How much is the BC Hydro attic insulation rebate?
The attic rebate is $0.02 × the R-value you add × the square footage, up to $900. For example, taking 1,000 sq ft from R-12 to R-50 adds R-38 and earns about $760. The work must be done by an HPCN contractor, and the rebate can combine with bonuses of up to $2,000 for multiple upgrades.
How long does attic insulation take to install?
Most attic jobs take one day, including baffles, air sealing and clean-up. Larger attics, or jobs that start with removing old or contaminated insulation, usually take two days. You can stay home while we work, and we cover floors and the route to the attic hatch.
Can you add new insulation on top of old insulation?
Yes, if the old insulation is dry, clean and not contaminated, we can top it up. If it is wet, mouldy, compressed or full of rodent droppings, we remove it first. If it looks like vermiculite, it must be tested for asbestos before anyone disturbs it.
Will more attic insulation stop ice dams and attic condensation?
Insulation helps, but air sealing and ventilation matter just as much. Warm, moist air leaking into the attic causes most frost, condensation and ice dams. That’s why we seal leaks and install baffles before adding insulation, so the attic stays cold and dry.
