Mr. Louis did an excellent job, he was very polite, courteous and knowledgeable about your products. He answered all of our questions, explained the installation and provided good after installation warranty assurances. After the installation the exterior and interior Solatube components looked so good, it was as if they were part of the original house construction, except now we have a well lit bathroom. Before leaving Mr. Louis did a excellent job cleaning up any construction debris inside and outside of the house. The Solar Guys can be proud to have an employee like Kevin Louis representing their company.
