What your neighbours say.
Bruce was fantastic when we were choosing a new exterior door. He gave us good suggestions and helped us find a door that looks great without going over budget.
We dealt with Steve for our window replacement and had a great experience. He was honest, helpful, and made sure we understood what we were getting. The Vinylguard windows are a big improvement.
Cliff installed a few new windows at our home and did a great job. He was on time, worked neatly, and cleaned up once he was finished. The rooms already feel warmer and quieter.
We had Steve help us with new vinyl windows from KV. He was easy to deal with, explained everything clearly, and didn’t make us feel pressured. The whole process went smoothly and the new windows look great!
Windows and doors that change how a home feels.
Black or white, classic or modern: a few looks to spark ideas for your own project.
Replacing windows shouldn't be complicated.
Most homeowners only do this once or twice, so it's easy to feel lost between salespeople, measurers and subcontractors. We handle every step ourselves, so you always know who to call.
Our team, start to finish
Consultation, measuring, ordering and installation all come from us. No hand-offs, no finger-pointing.
Efficient in every season
Insulated vinyl frames and glass options that keep winter drafts out, summer heat down and energy bills in check.
