Since we bought our home we had two more children, a set of twins. Our house is only a three bedroom, so we’re building two room addition onto the back.  We’ve been running over budget ,so we’ve been looking for ways to cut back on total cost. My husband is considering Do it Yourself Spray Foam Insulation as a way for him to complete some of the project without the cost of labor. The labor cost is what has been eating us alive. The cost of supplies have remained the same, but because of numerous setbacks, we have had to schedule more hours of expensive labor.
