What a Custom Door Manufacturer Actually Does
Custom door manufacturing means the door is built after you order it, to your measurements. It is not pulled off a shelf and trimmed to fit. At EHI Custom Doors, we make the slab, the frame and the brickmould from fiberglass in our own workshop, then install the finished set ourselves.
Plenty of companies that call themselves door makers are really dealers. They take your order, pass it to a factory, and hand the finished door to a separate installer. We do the whole job. The design, the manufacturing and the installation all happen under one roof, with one team, and they have for over 20 years.
We only build front and back entry doors, and only in fiberglass. No wood, no steel, no side projects. Every hour in the shop goes into doing that one thing well.
- Built to order, never pulled off a shelf
- Fiberglass slab, frame and brickmould
- Made in Ontario by the same team that installs it
- Front and back entry doors only

Inside an EHI Door: How We Build It
Anyone can show you a photo of a door. This is what is inside ours, layer by layer.
1Wood-Grain Surface
High Definition Panel Embossments give the skin the look of real oak or mahogany grain. You get the warm look without the fading, rotting or warping of a real wood door.
2Composite Rails on Every Edge
Composite PVC rails run around the full edge of the door, joined with mortise and tenon joints. They are 100% waterproof and hold the door together so nothing shifts over the years.
3LVL Frame Components
Laminated Veneer Lumber is one of the strongest engineered wood products made. Ours is wrapped in a PVC cap with a tongue-in-groove rail lock, so the structure is strong and sealed from moisture.
4Insulated Foam Core
A high-density, CFC-free polyurethane foam core gives six times the insulation of a traditional wood door. It also cuts down the sound that comes through the door.
5Executive and Recessed Panels
Both panel styles have deep shadow lines worked into the detail. The result is a door with real presence from the street, not a flat slab.
6Moulded Fiberglass Skin
The outer layer is a moulded fiberglass skin made to hold its finish through sun, rain and Toronto winters without cracking, warping or fading.
What We Build to Order
Every door starts from your opening and your taste. These are the choices you make with us, and each one changes what we build.
Front Entry Doors
Single doors and double doors, with or without sidelights and transoms, in classic panel styles or flush modern slabs.
Back Entry Doors
Back doors built from the same fiberglass as the front, in solid panel or glass styles for the yard, deck or patio.
Sizes and Heights
Doors in 6'8" and 8'0" heights, widths from 28 to 42 inches, and a 48 by 108 inch custom order size for openings that are not standard.
Decorative Glass
Glass from RegaLead, Verre Select, Fusion and ODL, plus frosted and privacy options, so you choose how much light and privacy you get.
Finishes and Colours
Oak Grain, Mahogany Grain and Smooth lines, plus Climatec two-tone doors with one colour inside and another outside.
Hardware and Locks
A multipoint locking system that engages at several points along the frame, in satin nickel, oil rubbed bronze or matte black.
Made to Order or Stock: What Changes
A stock door is built to a standard size and sold as is. A custom door is built to your opening. Here is how that plays out in practice.
| EHI made-to-order door | Typical stock door | |
|---|---|---|
| Size | Built to your measured opening | Standard sizes only, so the opening is often adjusted to fit the door |
| Who builds it | Our own workshop in Whitchurch-Stouffville | A factory, sold through a dealer or store |
| Who installs it | The same team that built it | Often a separate installer or a subcontractor |
| Materials | Fiberglass slab, frame and brickmould with a foam core | Varies by brand and price tier |
| Lead time | 4 to 6 weeks, plus 1 to 2 for custom glass | Sometimes in stock, sometimes ordered in |
| Warranty | Lifetime warranty on the fiberglass | Varies by brand |
Stock doors have their place, and we say so in our guide to custom doors vs stock doors. If your opening is standard and you need a door this week, a stock door may suit you.

Frequently Asked Questions
What is a custom door manufacturer?
A custom door manufacturer builds each door to order, to your measurements and design choices, instead of selling a standard door from stock. At EHI Custom Doors, we build front and back entry doors in fiberglass in our own workshop.
Are you a manufacturer or a dealer?
We are a manufacturer. Every door is made in our workshop at 4261 Bloomington Rd in Whitchurch-Stouffville, and our own team installs it. We do not use dealers or subcontractors.
How long does custom door manufacturing take?
Plan on 4 to 6 weeks from a confirmed order. If you choose custom glass, add 1 to 2 weeks.
What are your doors made of?
Fiberglass. The slab, frame and brickmould are fiberglass, built around a CFC-free polyurethane foam core with composite rails. We do not make wood or steel doors.
Can you build an oversized or unusual size?
Often, yes. Our standard range covers 6'8" and 8'0" heights, and we have a 48 by 108 inch custom order size. Send photos and measurements of your opening and we will tell you what is possible.
How much does a custom door cost?
A single door starts at $2,500 and a double door starts at $5,100, both installed. The final price depends on size, glass, finish, sidelights and hardware.
Do you make interior doors?
No. We build exterior front and back entry doors only, so that is where all of our experience sits.
Custom door manufacturing in Toronto should not mean waiting on a distant factory or settling for a stock size. EHI Custom Doors is a custom door manufacturer and builder that makes fiberglass front and back entry doors in its own workshop, to your opening.
Every door is backed by a lifetime warranty on the fiberglass, priced plainly from the start, and installed by the team that built it. To start, call 647-952-2311 or send us your quote request.
