  • Window Contractor in Thornhill, Ontario

    Hi there! My name is Kalen Shewan. I have about 10 years of experience in construction, starting out as a general labourer and now working professionally as an electrician. Over the years I’ve worked on a wide range of projects — from horse farms and residential homes to high-rise condos, data centers, and municipal pumping stations. This experience has given me a strong, practical skill set that I’ve used to help friends and family with all kinds of small projects, which I genuinely enjoy. I bring my own hand tools, power tools, ladders, and a vehicle to transport materials, so I’m fully equipped for most small jobs. If you're in York Region, I'd be happy to help with small projects around the house, including: -Minor repairs and patch-ups -Furniture assembly -Mounting and Installations -General handyman work If you’re not sure whether I can help, feel free to ask — I’m always happy to chat about your project.
