Recent Review: In 2012, we had all our windows replaced by SIW and the quality and support was excellent. Dave Martina was our main contact and he was very responsive. At the end of 2013, we continued the replacements by having SIW install 2 sets of French doors at the patio and a door on the side of the house that opens into the laundry room. Again, top quality and great installers. we will soon have the last couple of doors done and will again go to SIW. After nearly 2 years, our windows still look new and function perfectly.
