What We Manufacture
From Tudor-style buildings around Pickering Village to post-war homes built for the DIL munitions workforce, 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 work whether your home dates back to Ajax's wartime origins or went up last year in Northeast Ajax. 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 7 kilometres of Lake Ontario waterfront running through Ajax, a lot of back doors here see steady traffic to the yard and trail. We build it from the same solid fiberglass as our front doors, sized to your opening and finished to last.
Custom Back Door
Why Ajax Homeowners Choose EHI Custom Doors
Ajax was built almost overnight in the 1940s as a wartime munitions town, and a lot of that original housing stock is still standing today with doors that were never meant to last this long.
Built to Outlast Ajax's Original Wartime Bungalows
A lot of south Ajax homes started as post-war housing built quickly for the DIL munitions workforce in the 1940s, and the doors that came with them were never meant to last 80 years. Ours are.
Tudor Character for Pickering Village
Pickering Village's Tudor-style buildings around the old cobblestone courtyard give that part of Ajax real character, and we build doors that match it instead of a plain modern slab.
Real 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 vague ballpark quote.
Our Services
Every Ajax order goes through the same three steps under one roof in Whitchurch-Stouffville, whether your home dates back to the 1940s or went up last year.
Door Manufacturing
Your Ajax door starts as raw fiberglass at our Whitchurch-Stouffville workshop and comes out built for your exact opening, not picked from a warehouse shelf.
Get Your Door ManufacturedDoor Installation
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.
Get Your Door InstalledDoor Replacement
If your current door is decades past its prime, warped, drafty, or has been patched too many times, 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 an Ajax home shares the same foam core and moisture barrier, which is why we can back it with a lifetime warranty on the fiberglass instead of hoping it lasts. 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 matters more than it did when a lot of Ajax's original housing went up.
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 lake humidity or 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
A new entry door for your Ajax home does not start with someone driving out for a sales pitch. 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 Ajax 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 Ajax Homes
Ajax's housing runs from Tudor-style character near Pickering Village to established south Ajax streets and newer builds in the northeast, and each one calls for something different.
Tudor-Inspired Panels for Pickering Village
Around the historic courtyard and Tudor-style buildings of Pickering Village, a door with real panel depth in an Oak Grain or Mahogany Grain finish tends to suit the character better than a flat modern slab.
Lakefront Style for South Ajax
South Ajax's established streets near the 7 kilometre waterfront trail tend to suit a clean, modern finish in matte black or charcoal, often paired with a single glass insert.
Built to Fit Northeast Ajax's New Streets
Northeast Ajax has grown quickly with newer builds, and we build to your home's actual opening so your entrance is not identical to the one three doors down.
Real Pricing, No Guesswork
No vague estimates here. This is a real starting point for a new custom fiberglass door installed at an Ajax home.

Single Door
A single custom fiberglass door for an Ajax 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 Ajax entrance, starts at $5,100 installed. The same factors that shape a single door price apply here, scaled across two panels.
Serving Ajax From Our Whitchurch-Stouffville Workshop
Our workshop is out in Whitchurch-Stouffville, about 34 kilometres and roughly 30 to 35 minutes from Ajax depending on traffic.
That drive is short enough that the same small team building your door also installs it, without a regional dealer network or a subcontractor added into 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 Ajax?
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.
My house in south Ajax is one of the original post-war homes. Can you replace a door that old?
Yes, and it's a common job for us in Ajax. We measure your existing opening, even if it does not match a modern size chart, and build a solid fiberglass door to fit it exactly.
How far is your workshop from Ajax?
About 34 kilometres, roughly 30 to 35 minutes from Whitchurch-Stouffville depending on traffic. The same team that builds your door makes that drive to install it, so there is no separate dealer or subcontractor involved.
A custom door in Ajax has to work for a town with a genuinely unusual history, from Tudor-style Pickering Village to post-war homes built almost overnight for the wartime workforce. EHI Custom Doors manufactures, installs, and replaces fiberglass front and back entry doors from our own workshop in Whitchurch-Stouffville, about 30 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.
