Interior door installation
Replacing one door or every door in your home? We handle both.
Same crew from first measure to paint-ready finish — with a ten-year workmanship warranty on every install.

Single door swap to whole-house package: supplied, machined, hung, cased, and finished. Every material and style we install.
Lightweight builder-grade slabs. Cost-effective for bedrooms and closets, hung with the same care as solid-wood installs.
Heavier door, heavier hardware. Solid slabs need sized hinges and reinforced jambs to swing right for years, not just months.
New slab into your existing frame. We assess on site whether your jambs can carry the new weight, and tell you straight if reframing is needed.
Real interior doors on track systems — never cheap MDF closet kits. Solid framing, smooth tracks, soft-close hardware.
Flush doors with no hinge visible. Precise mortising with the manufacturer's template — TECTUS and other premium concealed hardware.
Why this work matters
Interior doors are touched dozens of times a day. When they’re hung right, they disappear into the trim line. When they’re not, you live with the friction — every season, every day.
You know the kind — the one you have to slam to latch. The one that scrapes the floor every July. The one with the wobbly handle you keep meaning to fix. Properly installed doors don't do any of that. They open with a fingertip, close with a soft click, and keep working that way for decades.
Ever been in a house where the doors are fine on their own, but the trim around them doesn't match the baseboards? Or the woodwork upstairs is a different style than down? That happens when different contractors do different jobs over the years. We install the whole trim package together — doors, the trim around them, baseboards, the works — so the home reads as one finished space.
Why hire us
Most contractors install doors. We finish them — frame, hinge, latch, casing, baseboard — with the precision of furniture work and 20+ years of practice across Toronto, Vaughan, Markham, and the GTA.
20+ years installing interior doors as finish carpentry — every reveal plumb to laser, every hinge mortise machined on jig, every casing scribed to wall. Family-owned since 2004. The kind of careful work that doesn't need callbacks six months later when seasons change.
Premium doors and hardware sourced through trade partners — not big-box stock. MDF, solid wood, hollow core, panelled, shaker, flush, French — we deliver the right material for your spec and recommend the appropriate hardware tier (ball-bearing, concealed, or European cassette) when you ask.
Real warranty on alignment, hardware function, and frame fit — covered for ten years. The catch: doors must be sealed on all six sides (face, back, top, bottom, both edges). Unsealed doors absorb humidity and warp; we walk through the painter handoff during the estimate visit so your warranty stays clean.
Hollow-core to solid-door upgrade? You probably need new jambs — builder-grade frames sag under solid-door weight and the door starts dragging within months. We assess the jamb structure on the estimate visit and tell you what's reusable and what isn't. No surprise change-orders mid-install.
How we work
From your first estimate visit through final cleanup — every door, every opening, every step planned and executed by the same team. No subs, no learning curve, no surprises.
Premium hardware
For flush doors and minimalist custom builds. We own the manufacturer’s jig — most contractors learn on your doors. Standard installs are fine with $10 ball-bearings; concealed pairs run $340. We’ll tell you straight when they’re worth the spend.
Cassette mortise locks need millimeter-precision pockets. We own a Virutex mortiser ($2K of European-engineered machinery) — not a $30 jig from the hardware store. Silent operation, factory fit, every time.

"I will never find a better contractor to do crown moulding than Expert. Arnie and another gentleman came to do my kitchen back in 2019 — from the time the bell rang till they left I timed them: only one hour and twenty minutes to do the entire work, from covering the floor to sizing, cutting, installing, and caulking. I was amazed how they were able to hide the joints. Recommended them to my sister the same year and she was super happy."
"I've used Expert Crown Moulding in both my old and new house. They do a fabulous job taking a boring hallway from drab tunnel to stunning. The guys are meticulous and consulted with me before making any design changes. Their ideas were great and I'm really happy with the finished product. Highly recommend."
"Excellent workmanship. Great attention to detail. Clean and professional. Great crew. We were very happy with the extensive work completed."
