No excuses. No runaround.

Three things that separate a crew that actually builds things from one that just talks about it.

Your job stays with our crew

We don't broker your project to whoever's cheapest. The same people who give you the quote are the ones doing the work. Every time.

No sub-contractors — your job stays with one crew

Your quote is your price

We write it down before work starts. We stick to it. If something unexpected changes the scope, we tell you before we act — not after.

Written quote locked in — no surprise invoices

Built to last outdoors

London winters are real. Every structure, fence, and wall we build accounts for freeze-thaw cycles, drainage, and the long haul — not just what looks good for photos.

Materials and methods chosen for the Canadian climate

London projects. Real results.

Every photo is a real job completed for a real London homeowner — no staged shots, no stock images.

Simple. Straight.

Nine years of word of mouth.

Leeonitis has operated on reputation since 2017. These are the kinds of projects that built it.

Our backyard went from a muddy mess to something we actually want to spend time in. The retaining wall alone was a massive project and they handled it like it was nothing. Solid crew.
James T.
Old South, London ON · Retaining wall + patio
They gave us a number and stuck to it. Did exactly what they said, when they said it. The interlocking stone patio is the best thing we've added to this house in 15 years of owning it.
Maria R.
Hyde Park, London ON · Interlocking patio
Got the fence, deck, and concrete pad all done at the same time. They coordinated everything themselves — I didn't have to manage a thing. Fast, clean, and exactly what we wanted.
