How long does Spray Foam Insulation last?

"They worked very efficiently and the crew leader Mike explained to me very clearly about the whole process before the work got started. They did what they say they’d do and I am very happy with them. We are having a third heat wave (90+ *F) in NY and I don't have to use AC as much as the year before."

"Excellent . The Estimator showed up 2 minutes before the appointed time & after a quick 20-minute survey of the exterior of the house, was able to give me a written estimate. The rest of the job was conducted in similar fashion. The installation crew showed up on time, were competant & courteous & completed job on time. When completed, I was asked to walk the job to make sure the cleanup was acceptable. Not enough "cold" time has gone by for me to comment on the reduction in heating costs but as for the work, this outfit gets my unqualified recommendation."
