JMack Exteriors
Why we built this division

For twenty years, our clients kept asking: can you do the outside too?

Now the answer is yes. JMack Exteriors is a dedicated division under the same JMack Builds Inc. roof — same Jesse, same crew, same standards. We focused on the categories homeowners trust us most to get right: the structural outdoor work where shortcuts show up two winters later.

The exterior commitment

Built to last. No shortcuts. Ever.

The structural work matters most on the outside — footings that hold, drainage that works, joints that stay tight through Ontario winters. We build with the same rigour you'd expect indoors.

  • 01Proper drainage and grading — not just what you can see
  • 02Frost-rated footings for decks and posts (not surface blocks)
  • 03Wood, PT, and composite — we'll match it to your house
  • 04Polymeric sand, edge restraints, and base prep that lasts
  • 05Permits handled when required (and we'll tell you when they are)
Cedar wrap-around deck with bench seating Featured
01 — Decks

Decks & restoration

From small back decks on city semis to multi-tier builds behind suburban homes. Pressure-treated, cedar, and composite — proper structural framing and footings, finishing details that match the house.

We also do honest deck restoration: sometimes the bones are good and we just need to replace surface boards and railings. We'll tell you which one you actually need.

  • New cedar, PT, and composite decks
  • Multi-level and roof decks
  • Frost-rated footings & proper structural framing
  • Glass, aluminum, and wood railings
  • Stairs, built-in benches, and planters
  • Restoration, board replacement & re-staining

Wood privacy fence
02 — Fencing

Fence repair & replacement

Horizontal, vertical board-on-board, lattice tops, gates with proper hardware. We work in the wood species that suits your home, budget, and privacy needs — and we build them right: real post holes, concrete set below frost line, stainless or hot-dipped fasteners. The small things that make a fence last ten years instead of three.

  • Horizontal and vertical wood fences
  • Privacy walls with cap and trim
  • Custom gates with self-closing hardware
  • Post replacement & section repair
  • Post-on-pipe systems for soft soil
  • Staining, sealing, and maintenance

Interlock paver walkway
03 — Interlock

Interlock & re-setting

Driveways, walkways, patios, and pool surrounds. Proper base prep, edge restraints, and polymeric joint sand — and yes, we re-set existing interlock that's heaved, sunk, or shifted. That's the call we get most often, and it's one of the things we love to fix.

  • New driveways, walkways, and patios
  • Re-leveling and re-setting existing interlock
  • Concrete & natural stone pavers
  • Permeable interlock options
  • Borders, soldier courses, and accents
  • Polymeric sand & sealing
