Carpentry is where a renovation earns its character

You can renovate every surface in a home and still have it feel flat. Custom carpentry is what gives a space presence — the weight of a properly hung door, the line of a staircase that follows the geometry of the house, trim that sits tight against every angle, every time.

We have delivered custom carpentry and millwork in Kitchener, Waterloo and Cambridge for over 10 years. Every piece is held to documented tolerances.

Trim and door installation

Trim, Casing and Door Installation

Trim is the frame your renovation lives in. We install interior trim, casing, and door packages to tolerances that make the difference between a home that looks finished and one that looks crafted.

  • Baseboard, casing, and crown moulding installation
  • Interior door hanging and hardware fitting
  • Wainscoting, board and batten, wall panelling
Custom stair and railing

Stairs and Railing

A staircase is one of the first things you see in a home. We design and build custom stair systems that are structurally sound, code-compliant, and visually distinctive.

  • Full staircase design and construction
  • Hardwood treads, risers, and stringers
  • Custom wood, glass, and metal railing systems
Custom millwork and built-ins

Custom Millwork and Built-Ins

Custom millwork is the element that makes a renovation feel complete — built-ins, shelving, and architectural woodwork designed and built specifically for your home, not selected from a catalogue.

  • Built-in shelving, bookcases, entertainment units
  • Fireplace surrounds and mantels
  • Mudroom and entryway built-in systems
Cabinetry installation

Cabinetry Installation and Fitting

Cabinet installation is one of the most tolerance-sensitive trades in a renovation. We install kitchen, bathroom, and utility cabinetry to reveals and alignment standards most installations do not achieve.

  • Kitchen cabinet installation and levelling
  • Bathroom vanity and storage installation
  • Hardware installation and alignment

Carpentry held to documented tolerances

Most contractors work to a loose standard of "it looks good." We work to documented tolerances that define what good actually means, measured against every installation.

Tile lippageUnder 1mm
Grout line consistencyWithin 0.5mm
Stair riser height varianceUnder 3mm
Moulding joint gapHairline only
Craftsmanship detail
The same standard that governs our renovations governs every piece of carpentry we install.

Pillar Six, Tradesmanship, defines the exact tolerances every carpenter on our team is held to. Cabinet reveals within 1.5mm. Tile lippage under 1mm. No exceptions.
