Attic Insulation & Removals
We offer a range of energy-efficient solutions to upgrade your attic insulation. Our services include attic insulation removal, blown-in fibreglass or cellulose insulation, fibreglass batts, and spray foam insulation.
A properly insulated and well-ventilated attic helps to:
Keep your home cooler in the summer
Keep your home warmer in the winter
Reduce energy bills
Minimize the risk of mold and moisture issues
Expel damaging excess heat that can strain your air conditioning system and overheat upper floors
Remove excess moisture from kitchens, laundry rooms, and bathrooms that vent through the attic—preventing mold, mildew, and wood rot
If you have rodent concerns, we can remove existing insulation to expose potential entry points before reinstalling new insulation. We also offer a disinfectant spray to neutralize odors and contaminants.
Air leakage can lead to condensation and moisture problems in your attic. To address this, we use low-expansion foam to air seal plumbing and electrical penetrations where air is escaping.
Proper ventilation is a critical component of a healthy attic. Our team can professionally assess your attic’s ventilation needs and provide customized recommendations and upgrades to ensure long-term performance and comfort.

Drill & Fill Exterior Walls
Do you have an older home with little or no insulation in the walls? Our drill-and-fill insulation process allows us to insulate exterior walls without removing drywall.
Our process includes:
Drilling from the interior through lath and plaster or drywall
Drilling from the exterior through wood siding, shingles, or stucco
Filling wall cavities with high-performance blown-in cellulose insulation
This minimally invasive method improves comfort, increases energy efficiency, and helps lower heating and cooling costs—while preserving your existing walls.
Sound Dampening
Sound dampening solutions can be complex, and every space requires a tailored approach. We offer a range of effective options to help reduce unwanted noise, including:
Drill & fill insulation for ceiling cavities
Drill & fill insulation for interior walls
Rockwool batt insulation for exposed walls or ceilings
Call or email us today to discuss your sound dampening needs and find the right solution for your space.
Crawlspace Insulation
Uninsulated crawlspaces can result in significant heat loss and higher energy bills. We offer several effective, energy-saving solutions to improve comfort and efficiency, including:
Spray foam insulation for exterior walls and joist ends
Installation of a poly vapour barrier over the crawlspace floor
Insulating the crawlspace ceiling
Proper crawlspace insulation helps reduce heat loss, control moisture, and improve overall indoor comfort.
