What We Manufacture
From King Street's 19th-century heritage buildings to homes near Victoria Beach and Victoria Hall, 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 real character whether it's inside one of Cobourg's four heritage conservation districts or a block from the beach. 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
This close to Lake Ontario and Victoria Beach, a Cobourg back door sees plenty of daily use. We build it from the same solid fiberglass as our front doors, sized to your opening and finished to last.
Custom Back Door
Why Cobourg Homeowners Choose EHI Custom Doors
Cobourg packs four heritage conservation districts and a real sand beach into one compact waterfront town, and a door company here needs to respect both instead of treating it like a generic small market.
Built for Four Heritage Conservation Districts
Cobourg has four separate heritage conservation districts under the Ontario Heritage Act, more than almost anywhere else we serve, and homes inside them deserve a door that respects that history.
Steps From a Real Sand Beach
Victoria Beach runs more than a kilometre of white sand along Lake Ontario, and homes near it deal with real lake wind and moisture. Our foam core and moisture barrier are built for exactly that.
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 Cobourg order goes through the same three steps under one roof in Whitchurch-Stouffville, whether your home is in a heritage district or near the beach.
Door Manufacturing
Your Cobourg 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 has taken a beating from lakefront weather, 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 Cobourg home shares the same foam core and moisture barrier, which matters this close to the lake. 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 near an open Lake Ontario shoreline.
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 Cobourg home does not start with a long drive 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 Cobourg 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 Cobourg Homes
Cobourg's compact downtown means heritage streets, beachfront homes, and grand civic architecture all sit close together, and each calls for a different look.
Heritage Panels for Downtown Cobourg
Along King Street's 19th-century commercial core, a door with real panel depth in an Oak Grain or Mahogany Grain finish suits the streetscape better than a flat modern slab.
Beachside Style Near Victoria Beach
Homes closer to the sand and the waterfront tend to lean toward clean modern lines with larger glass panels to take in the lake view.
Grand Character Near Victoria Hall
Homes around Victoria Hall's National Historic Site setting suit a door with real detail and hardware, built to match a more elevated architectural standard.
Real Pricing, No Guesswork
No vague estimates here. This is a real starting point for a new custom fiberglass door installed at a Cobourg home.
Single Door
A single custom fiberglass door for a Cobourg 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 Cobourg entrance, starts at $5,100 installed. The same factors that shape a single door price apply here, scaled across two panels.
Serving Cobourg From Our Whitchurch-Stouffville Workshop
Our workshop is out in Whitchurch-Stouffville, roughly 105 kilometres and about an hour and a half from Cobourg depending on traffic. It is on the farther end of our service area, and we are upfront about that.
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.
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 Cobourg?
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 in one of Cobourg's conservation districts?
Yes. Cobourg has four separate heritage conservation districts, and homes inside them may need a design that fits the area's guidelines. We build with real panel depth and finish options that suit a heritage streetscape, and work around any approval your home requires.
How far is your workshop from Cobourg?
Roughly 105 kilometres, about an hour and a half depending on traffic. It is on the farther 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 Cobourg has to hold up to four heritage conservation districts and a real lakefront beach, all packed into one compact town. EHI Custom Doors manufactures, installs, and replaces fiberglass front and back entry doors from our own workshop in Whitchurch-Stouffville, about an hour and a half 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.
