What We Manufacture
From Victorian and Gothic style homes on Main Street Unionville to the walkable streets of Cornell and Berczy Village, we build every front and back entry door to fit your home's real opening. Every door leaves our workshop in solid fiberglass, finished the way you picked it.
Custom Front Doors
Your front door has to hold up whether it sits on a 230-year-old streetscape or a brand new build near the tech corridor. We build it in solid fiberglass to your exact size, in finishes from Oak Grain and Mahogany Grain to Smooth and Contemporary.
Custom Full-Glass Front Door with Sidelights
Custom Back Doors
Markham's mix of older lots and newer townhome-style streets means back doors see a lot of different daily use. We build it from the same solid fiberglass as our front doors, sized to your opening and finished to hold up.
Custom Back Door
Why Markham Homeowners Choose EHI Custom Doors
Markham stretches from a Main Street that has barely changed since 1794 to a Highway 7 corridor full of tech offices, and the right door company should be able to work with either end of that.
Built for Markham's Tech-Corridor Pace
A lot of Markham homeowners work in the Highway 7 tech corridor and do not have an evening free for an in-home sales pitch. Our whole process runs on photos and a digital quote instead.
Respecting a 230-Year-Old Main Street
Main Street Unionville has barely changed since 1794, with heritage Victorian and Gothic style homes still standing along it. We build doors that respect that history instead of pushing a stock design that clashes with it.
Clear Pricing, No Guesswork
Single doors start at $2,500 installed and double doors start at $5,100, with the final number set by size, glass, finish, and hardware, not a surprise after a home visit.
Our Services
Every Markham order goes through the same three steps under one roof in Whitchurch-Stouffville, with nothing handed off between a manufacturer, an installer, and a separate sales office.
Door Manufacturing
Your Markham door starts as raw fiberglass at our Whitchurch-Stouffville workshop and comes out built for your exact opening, not sitting pre-made on a shelf.
Get Your Door ManufacturedDoor Installation
The same crew that builds your door installs it, so nothing gets lost between a factory and a subcontractor on install day.
Get Your Door InstalledDoor Replacement
If your current door is warped, drafty, or has been patched too many times, we replace it with a custom fiberglass door built to your real opening instead of a generic stock size.
Get Your Door ReplacedWhat Makes an EHI Door Different
Every door we build for a Markham home shares the same foam core and moisture barrier, which is why we back it with a lifetime warranty on the fiberglass. Here is what actually goes into it.
CFC-Free Polyurethane Foam Core
Every door is built around a CFC-free polyurethane foam core, giving roughly six times the insulation of a plain wood door, which adds up over a full Markham winter.
Tongue-in-Groove Moisture Barrier
A tongue-in-groove rail system with composite PVC rails keeps every seam sealed against water. No warping, no swelling, no rot working in from melting snow.
Lifetime Fiberglass Warranty
Fiberglass will not crack, rot, or break down the way wood and steel eventually do, so every door we build carries a lifetime warranty on the fiberglass itself.
Multipoint Lock System
Every door comes standard with a multipoint lock engaging the frame at several points instead of one deadbolt, in finishes like satin nickel, oil rubbed bronze, and matte black.
How It Works
Getting a new entry door for your Markham home does not require clearing an evening for a sales visit. It starts with a photo and a form, and stays simple from there.
Request Your Digital Quote
Send a few photos of your entrance or fill out our online form and you will hear back with an accurate digital quote and some design direction, no appointment required.
Choose Your Perfect Design
Work with our team to lock in the door style, glass, finish, colour, sidelights, and hardware. Pricing updates as you make each choice.
Approve Your Quote
Once the design and the number look right, approve the quote. Skipping the in-home sales visit is what keeps that number honest.
Final Measurement Visit
After your quote is approved, one of our installers visits your Markham home to take exact measurements before manufacturing starts.
Custom Manufacturing and Professional Installation
Your door gets built specifically for your home, then installed by our own crew, with a full check before we leave to confirm everything opens, closes, and locks right.
Door Styles That Fit Markham Homes
Markham's housing splits by era and by design philosophy as much as by neighbourhood. Main Street Unionville keeps its 19th-century character, Cornell and Berczy Village were built as walkable New Urbanist communities, and Milliken Mills is one of the town's oldest pockets.
Heritage-True Doors for Main Street Unionville
Victorian and Gothic Revival details are still visible along Main Street, and a door with real panel depth in an Oak Grain or Mahogany Grain finish tends to suit that streetscape far better than a flat modern slab.
Walkable New Urbanist Style for Cornell and Berczy
Cornell and Berczy Village were both designed with front porches facing the street and garages tucked to the rear, so the entry door is seen up close. A clean, well-proportioned design matters more here than on a typical subdivision street.
Built to Fit Milliken Mills' Older Stock
Milliken Mills is one of Markham's oldest neighbourhoods, with openings that do not always match a modern size chart. We measure and build to the real opening instead of forcing a standard size.
Real Pricing, No Guesswork
No vague estimates here. This is a real starting point for a new custom fiberglass door installed at a Markham home, before your specific choices are added.
Single Door
A single custom fiberglass door for a Markham home starts at $2,500 installed, backed by a lifetime warranty on the fiberglass. The final number depends on size, glass, finish, and hardware like a single point versus multipoint lock.
Double Door
A double door, sized for a wider Markham entrance, starts at $5,100 installed. The same factors that shape a single door price apply here, scaled across two panels.
Serving Markham From Our Whitchurch-Stouffville Workshop
Our workshop sits in Whitchurch-Stouffville, about 21 kilometres and roughly 20 to 25 minutes from Markham depending on traffic and which part of town you're in.
That short drive means the same small team that manufactures your door also installs it, without a regional dealer network or an extra subcontractor in the mix.
Awards & Recognition
Efficient Home Improvements, the company behind EHI Custom Doors, won a HomeStars Best of Award in 2021 and has held HomeStars Verified status every year since, renewed annually on real customer reviews and a background check.

Frequently Asked Questions
How much does a custom door cost in Markham?
A single custom fiberglass door starts at $2,500 installed, and a double door starts at $5,100 installed. The exact number moves with size, glass, finish, and hardware, but those two figures are the real starting point.
Can you match a door to a heritage home on Main Street Unionville?
Yes, though homes inside Markham's heritage conservation districts may need a design that fits the area's guidelines. We can build to match a Victorian or Gothic Revival look, and we are happy to work around any heritage approval your home requires.
How fast can I get a quote if I work in the tech corridor and do not have time for a home visit?
Send us a few photos of your entrance or fill out our online form and we will get back to you with an accurate digital quote, usually without needing to schedule anything in person until the final measurement.
A custom door in Markham should not have to choose between fitting a 230-year-old Main Street home and keeping up with a fast-moving tech corridor. EHI Custom Doors manufactures, installs, and replaces fiberglass front and back entry doors from our own workshop in Whitchurch-Stouffville, about 20 minutes away.
Every door carries a lifetime warranty on the fiberglass, gets priced honestly from the first quote, and is installed by the same team that built it. If you want a door built for your actual home instead of a standard size, call us at 647-952-2311 or fill out the form above for a free quote.
