Home Insulation Contractor in the Lower Mainland, BC
Western Insulation is a Langley-based home insulation contractor serving Metro Vancouver and the Fraser Valley since 1998.

Where Lower Mainland Homes Lose Heat
Every house leaks heat in the same order: the attic first, then air leaks, then basements and crawlspaces, then walls. Fixing them in that order gives you the most comfort for the money.

What a Whole-Home Insulation Upgrade Changes
Even temperatures
No more cold bedrooms over the garage or a hot top floor.
Lower heating bills
Less heat lost means your furnace or heat pump runs less.
Fewer drafts and moisture problems
Air sealing and proper insulation keep damp, warm air out of attics and walls.
Quieter rooms
Insulated walls and floors cut noise between rooms and from outside – see soundproofing insulation.
Which Home Insulation Upgrade Should You Do First?
Priority | Upgrade | Why |
1 | Attic top-up + air sealing | Biggest heat loss, lowest cost per sq ft, attic rebate up to $900 |
2 | Basement / crawlspace walls + rim joists | Cold floors and moisture; rebate up to $1,200 |
3 | Exterior walls | Best done during renovations or re-siding; rebate up to $1,200 |
4 | Soundproofing and interior walls | Comfort and privacy; not rebated |

Frequently Asked Questions
Which part of my home should I insulate first?
Start with the attic. It is usually the biggest source of heat loss, the cheapest area to insulate per square foot, and an attic top-up to R-50 earns the BC Hydro attic rebate. Next come air sealing, then basement and crawlspace walls, then exterior walls, which are easiest to insulate during a renovation or re-siding.
Do I need an energy audit to get an insulation rebate in BC?
No. The BC Hydro and FortisBC Home Renovation Rebate for insulation does not require an EnerGuide energy evaluation. What you need is an HPCN contractor and an invoice showing the area insulated, the starting and final R-value and the insulation type. The old federal Greener Homes Grant, which did require audits, is closed.
How much does home insulation cost?
It depends on what you upgrade. A blown-in attic top-up typically runs about $1,500 to $2,450 for 1,000 sq ft before rebates, and closed-cell spray foam about $3 to $5 per square foot. A whole-home package is quoted after an assessment, and rebates can reach $5,500 plus bonuses.
Can you insulate during a renovation?
Yes, a renovation is the best time to insulate walls, because the cavities are open. We schedule around your contractor’s drywall date, install batts or spray foam, and can provide the rebate paperwork for exterior walls. Tell us early so the insulation inspection, if required, fits the schedule.
What eco-friendly insulation options do you offer?
Fibreglass loose-fill like Owens Corning ProPink is made with high recycled content and is formaldehyde-free, and fibreglass batts are similar. The greenest choice is often simply more insulation where it matters most, because the energy you save over the years outweighs the material’s footprint.
