Same standard, now in your backyard.
Two years in the making. Precision repairs and custom outdoor builds — decks, fencing, interlock, retaining walls and full landscape design across Toronto and the GTA.
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.
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)
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
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 & 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
Retaining walls & landscape
Engineered retaining walls, gabion baskets, decorative stonework, garden bed builds, and full backyard design. We can take a sloped, neglected yard and give you flat usable space — done right so it stays that way through Ontario winters.
- Engineered & decorative retaining walls
- Gabion baskets & natural stone features
- Raised garden beds & planters
- Drainage & grading correction
- Mulch, soil, and planting installs
- Full-yard transformations
