About this project
A systematic seal of the places a Calgary house loses heat: exterior door weatherstripping and sweeps, window sash and frame sealing, electrical outlet and switch gaskets on exterior walls, rim joist gaps, attic hatch, dryer and bathroom vent dampers, and sill plate sealing in the basement. Finished with a room-by-room report of what was sealed and what still needs proper work.

Questions homeowners ask
Does draft-proofing actually make a difference in Calgary?
Yes, and it is usually the best value per dollar of any heating upgrade. Air leakage accounts for a large share of heat loss in older Calgary homes, and sealing costs hundreds rather than thousands.
How much does draft-proofing cost?
A bungalow package costs $690–$790 in 2026, a two-storey $966–$1,100. Adding rim joist insulation — often the single leakiest part of a Calgary basement — brings a bungalow to about $1,345.
Can a house be sealed too tightly?
It can. We check that your furnace and hot water tank still get the combustion air they need, and if sealing would push the house past safe levels we say so and recommend ventilation rather than more sealing.
