What We Manufacture
From heritage homes near Old Milton's Main Street to the newer streets out toward Harrison and Willmott, 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 needs to handle real weather swings this close to the Niagara Escarpment. 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
With Rattlesnake Point and Crawford Lake nearby, a lot of Milton households are in and out the back door for the outdoors. We build it from the same solid fiberglass as our front doors, sized to your opening and finished to last.
Custom Back Door
Why Milton Homeowners Choose EHI Custom Doors
Milton sits right on the Niagara Escarpment and has grown faster than almost any other town in Canada over the past two decades, and a door here needs to handle both the terrain and the pace of growth.
Built for Escarpment Weather
Milton sits right on the Niagara Escarpment, and the elevation change around Rattlesnake Point and Crawford Lake means real wind and weather swings that flatter towns do not see as much. Our foam core and moisture barrier are built for it.
Character for Old Milton's Main Street
Old Milton's downtown core has real heritage character, and the homes around it deserve a door with real panel depth, not a big box import.
Real Pricing While the Town Grows
Milton has been one of Canada's fastest growing municipalities for years, and a lot of that growth comes with builder-grade pricing baked into a mortgage. Ours is separate and honest, starting at $2,500 installed.
Our Services
Every Milton order goes through the same three steps under one roof in Whitchurch-Stouffville, whether your home is downtown or in one of the newer subdivisions.
Door Manufacturing
Your Milton door starts as raw fiberglass at our Whitchurch-Stouffville workshop and comes out built for your exact opening, not picked from a warehouse shelf.

The crew that installs your door is the same crew that built it, so nothing gets lost between a factory and a subcontractor on install day.

If your current door is warped, drafty, or was simply the cheapest option the builder offered, we replace it with a custom fiberglass door built to your real opening.
Get Your Door ReplacedWhat Makes an EHI Door Different
Every door we build for a Milton home shares the same foam core and moisture barrier, which matters more this close to the escarpment. 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 counts for a lot at Milton's higher elevation.
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 or spring rain.
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
A new entry door for your Milton home does not start with a commissioned sales rep at your door. It starts with a few photos and a form.
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 Milton 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 Milton Homes
Milton's housing splits by when it was built almost as much as by neighbourhood, from Old Milton's heritage core to the east end's 2000s growth and the newer west end streets.
Heritage Panels for Old Milton
Around Old Milton's Main Street, a door with real panel depth in an Oak Grain or Mahogany Grain finish suits the historic downtown better than a flat modern slab.
Contemporary Style for Milton's East End
Dempsey, Clarke, Beaty, and Coates lean toward smoother, more contemporary panel doors in matte black or charcoal, often with a single glass insert.
Built to Fit a Fast-Growing Town
Milton has been one of Canada's fastest growing municipalities for years, and a lot of what went in came straight from a builder's standard list. We build to your home's actual opening instead of a stock size.
Real Pricing, No Guesswork
No builder-grade upgrade fees here. This is a real starting point for a new custom fiberglass door installed at a Milton home.

Single Door
A single custom fiberglass door for a Milton 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 Milton entrance, starts at $5,100 installed. The same factors that shape a single door price apply here, scaled across two panels.
Serving Milton From Our Whitchurch-Stouffville Workshop

That drive is still worth it for the same reason it is everywhere else we serve, the same small team that manufactures your door also installs it, with no regional dealer network or subcontractor in the mix.

Frequently Asked Questions
How much does a custom door cost in Milton?
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.
Will a fiberglass door hold up to the weather swings near the Niagara Escarpment?
Yes. Every door uses a tongue-in-groove rail system with composite PVC rails that keeps every seam sealed, so the wind and moisture swings common at Milton's elevation do not lead to warping or swelling.
How far is your workshop from Milton?
About 84 kilometres, roughly an hour depending on traffic. It is on the longer end of where we serve, but the same team that builds your door still makes that drive to install it, so there is no separate dealer involved.
A custom door in Milton has to handle real escarpment weather and stand out in one of the fastest growing towns in Canada. EHI Custom Doors manufactures, installs, and replaces fiberglass front and back entry doors from our own workshop in Whitchurch-Stouffville, about an hour 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.
