We just want to say "Kudo's for a job well done!" Rob and his team did an excellent job on the installation and they were careful to respect our home and exceeded our expectations. The install went smoothly and looks very professional..."

I was very impressed with Steve and his son. The communication was great either by phone or email. They came to the house on time and got right to work. The install was clean and looked very good. His price was very competitive and lower than these large companies. I will use S&L for all my properties.
