We first had Ascon 3 years ago replace 4 windows. The work was of excellent quality, done on schedule, and the people honest, hard working and a pleasure to deal with. Last but not least, the price was reasonable and the owner knows his job and can provide valuable advice. This company takes pride in their work and ensure their clients are satisfied. We were so pleased with them that we had the rest of our windows, a total of 14 (including 4 bay) as well as sliding patio doors and a front door done by them as well. Each time we received the same great service. This company is a gem!
