    From pool openings and closings to demolition and foundation waterproofing — I do it all. I’m a versatile handyman serving the Greater Toronto Area with experience spanning landscaping construction (interlock, pavers, retaining walls), roofing repairs, drywall, carpentry, concrete work, fencing, garage doors, painting (interior/exterior), window and door installations, light electrical, plumbing fixtures, appliance installs, pressure washing, pool maintenance, junk removal, gardening, welding, and pretty much everything in between. My skills come from the ground up. My father is a condo developer in Mongolia — I grew up on job sites, watching and doing real construction work from a young age alongside experienced crews. That hands-on upbringing, combined with my Civil Engineering Technology diploma and current studies toward a Civil Engineering degree at McMaster University, means I bring both deep practical skill and technical knowledge to every job. I’m 30, reliable, have my own vehicle, and will show up on time. I’m trilingual in English, Russian, and Mongolian, and I work with integrity — if I’m ever unsure about something, I’ll say so and figure it out properly rather than guess. No shortcuts, no excuses. Do it once and right
