How to Specify Interior Doors for Multi-Unit Projects in Calgary
Interior doors are one of the most repeated line items in any multi-unit project — and one of the most commonly under-specified. Getting the material, finish, and supplier right early saves significant cost and time at close-out. This guide covers what Calgary builders and developers need to know before they commit to a door schedule.
Start with the Right Material
The material decision shapes everything downstream — cost, lead time, maintenance, and warranty exposure. For multi-unit residential in Alberta, three materials come up most often: hollow-core, solid wood, and WPC (Wood Plastic Composite).
Hollow-core doors are the cheapest option at point of purchase but generate the most callbacks. They dent easily, transmit sound poorly, and have a short effective lifespan in rental and high-occupancy environments. For any project where quality is part of the sales pitch — condos, townhouses, show suites — hollow-core undermines the finish.
Solid wood doors carry a premium price and perform well aesthetically, but Alberta's climate creates real long-term risk. The humidity swing between dry winter heating and humid summer conditions causes solid wood to expand, contract, and eventually warp or stick. In multi-unit buildings where consistent performance across all units matters, this variability is a liability.
WPC interior doors have become the specification of choice for builders and developers who want the aesthetic of solid wood without the maintenance exposure. The composite core is dimensionally stable, waterproof, and termite-resistant — it performs consistently across all rooms, including bathrooms, ensuites, and laundry spaces where moisture is a constant factor. For projects where the door needs to look good on day one and still look good five years later, WPC is the lowest-risk material choice.
Build a Door Schedule Early
The biggest mistake builders make with interior doors is treating them as a late-stage decision. Doors are manufactured to order — lead times for custom sizes and finishes run 6–12 weeks from confirmed order. On a project with 50, 100, or 200 doors, a late door schedule means a delayed close-out.
A door schedule should be confirmed alongside rough-in framing — certainly no later than lock-up. It should include:
- ✓Door quantity per unit and total across the project
- ✓Opening dimensions for each door type (width, height, swing direction)
- ✓Design or style selection per room category (e.g. all bedrooms one design, bathrooms another)
- ✓Finish selection — paint, melamine, wood grain laminate, or high gloss
- ✓Hardware requirements — lever handle sets, hinges, frames, and casing
- ✓Any non-standard openings that require custom sizing
A complete door schedule submitted to your supplier early allows for accurate quoting, production scheduling, and staged delivery that aligns with your construction timeline — not your supplier's.
Volume Matters — Use It
Multi-unit projects create buying leverage that single-home purchases do not. Most quality door suppliers offer volume programs — tiered discounts that scale with the number of doors on a single order. If your supplier does not offer volume pricing on orders of 10 or more doors, you are leaving money on the table or working with the wrong supplier.
Beyond the per-door discount, a volume relationship with the right supplier unlocks other practical benefits: a dedicated account manager who knows your project, priority production scheduling, site delivery coordinated to your construction phase, and pre-sale support for show suites or model homes. These are not extras — they are the baseline for how a professional door supply relationship should work on a development project.
When evaluating suppliers, ask specifically about their developer program — not just their catalogue price list. The difference between standard retail pricing and a developer rate on a 50-door order is material.
Specify All-In Pricing — No Hidden Extras
Door quotes have a way of expanding between initial estimate and final invoice. The door slab is quoted, then ironmongery is added, then casing, then delivery, then installation. On a large project, line-item surprises at close-out create budget problems that are difficult to resolve after the fact.
When requesting quotes, be explicit that you want all-in pricing: door slab, hardware (hinges, lever handles, lock set), frame, and casing included in the per-unit rate. Any supplier unwilling to quote on this basis is signalling that their headline number is not their real number.
At Cyrus Doors & Joinery, every quote to builders and developers includes ironmongery and casing as standard — no separate line items, no close-out surprises. If pricing changes at all between quote and invoice, it is because the project scope changed — not because we found items to add.
Show Suite and Model Home Doors
The show suite is where buyers make their decision. Interior doors are one of the most tactile elements in a show suite — prospects open and close them, run their hands along the finish, and judge the build quality of the entire project by how they feel. Specifying a premium WPC door with a high-gloss or wood grain laminate finish in a show suite sets a quality standard that is achievable and repeatable across all units.
Many of our developer clients use show suite doors as a design anchor — presenting the premium finish option as standard in the suite, with alternative finishes available at different price points for purchasers who want to customise. This creates an upsell opportunity while giving every buyer a strong first impression.
We offer sample door display support for show suites and model homes — contact us to discuss what makes sense for your project.
Evaluating a Door Supplier in Calgary
Not all door suppliers are set up to handle development-scale projects. When evaluating a supplier for a multi-unit project, the questions that matter most are:
- ✓Can they supply custom sizes, or only standard dimensions?
- ✓What is their realistic lead time from confirmed order to site delivery?
- ✓Do they offer a developer or volume pricing program?
- ✓Is their pricing all-in, or will hardware and casing be quoted separately?
- ✓Do they provide a dedicated contact for the duration of the project?
- ✓What does their warranty cover, and what does it exclude?
- ✓Can they coordinate staged deliveries to match your construction schedule?
A supplier who cannot answer these questions clearly at the quoting stage will not be easier to work with once production has started. The door schedule is one of the cleaner lines in a complex build — your supplier should make it feel that way.
See the Doors Before You Specify
Finish decisions — particularly between melamine, wood grain laminate, and high gloss — are difficult to make from a catalogue image or a small physical swatch. On a project where the same door is repeated 50 or 100 times, a finish decision made from a screen is a risk.
Our Calgary Viewing Centre has a selection of door designs and finishes on display, giving you a real sense of the quality, texture, and finish options available. Bring your floor plans, your interior colour palette, and your door schedule — we will help you confirm the right specification before you commit. No obligation, no pressure, and no samples shipped to site.
