After being flooded in July with the rest of the GTA, we re-did our basement and opted to insulate what wasn't done previously. We were told that sprayfoam was the way to go but make sure to get someone "good" and at the right level and price. Boy did Airseal deliver. Prompt, professional and courteous. Thanks to Airseal, we have said good bye to our drafty basement and look forward to "warm winters" and "cool summers"!
