I recently read a newsletter in the Spring on HomeStars with respect to a product called Insuladd. I live in a century home (double brick) no insulation. I decided to give this product a try and hired Dan of Greener Pastures painting to paint the entire exterior of my house using the Insuladd additive. Dan was very professional (as was all of his tradesmen). The job was completed on time and looks fantastic. No mess, no fuss. what a wonderful team Dan has. Thanks for the great job Dan. Maureen
