Vinyl Tech quoted us on a Sunday. He made sure to explain all intricacies of their windows and showed us a variety of their work in a picture album. They were in the pictures too so I'm confident it wasn't just pictures of nice windows!
Windows were made within 2 weeks and installed in 1 day. One was made incorrectly so he advised us to hold back some payment and he'd be back in a few days. Windows look great. Some smudging as a result of dirty hands and fresh silicon but they promised to clean that up when they installed the last window.
