How much does it cost?

Not as much as you might think.  Depending on the selections you make during our consultation your spray foam insulation will cost you between 20 and 75% more than traditional insulation.  An average 1400 square foot bungalow insulated with spray foam insulation would only cost about $ 1700.00 more than with professionally installed fibreglass. On your mortgage  based on a 25 year amortization this is only about $ 9.00/month or $ 108.00/year.  Spray foam insulation will save you many times this cost every year so the repayment period is basically the first month you turn on your heater or your air conditioner.
