Steel vs Fibreglass Entry Doors
Both Dorplex steel and Dorplex fibreglass doors are built for Canadian weather and carry strong manufacturer warranties. The best choice depends on your budget, design preferences, and how much maintenance you want long-term. :contentReference[oaicite:1]{index=1}
Steel Entry Doors
- Great value – typically more budget-friendly than fibreglass
- High strength and solid feel for everyday security
- Smooth or woodgrain textures available
- Factory-painted finishes in a wide selection of colours
- Energy Star® certified options for better comfort and efficiency
Fibreglass Entry Doors
- Premium look that closely mimics real wood grain
- Won’t dent, crack, split, or splinter like wood can
- Excellent energy efficiency with insulated cores
- Ideal for stains and richer colours on the exterior
- Often the best long-term durability with minimal maintenance

During your consultation, we’ll bring catalogue examples and photos so you can see the different Dorplex collections and glass options that fit your home.

Factory Paint & Stain Colours
Dorplex entry doors are finished with durable, factory-applied coatings so your new door looks great and stands up to the elements.
Paint Colours
Choose from a wide range of solid paint colours — from classic whites and browns to deep blues, greens, and bold accent colours. The finish is smooth, low-maintenance, and designed for exterior use.
Stain Finishes
Fibreglass doors can be finished in rich woodgrain stains that closely mimic real wood without the upkeep. Perfect if you want the look of a wood door with the durability of fibreglass.
During your estimate, we’ll show you actual colour samples so you can see how different paint and stain options will look with your brick, siding, and trim.

Quality Hardware, Locks & Hinges
Your front door should feel solid, secure, and easy to use every day. That’s why we pair Dorplex entry systems with quality hardware packages and proper installation.
- Deadbolt and handle sets available in modern and traditional styles
- Multiple finish options to match your interior and exterior décor
- Heavy-duty hinges and reinforced strike plates for better security
- Multi-point lock options available on select door configurations
We’ll review hardware styles and finishes with you in person so your new entry door both looks the way you want and feels secure every time you close it.

Complete Entry Door System – Frame, Sill & Weatherstripping
An entry door is more than just the slab. A proper replacement includes the entire Dorplex door system so you get better performance, security, and long-term reliability.
- New door frame and jambs custom-sized to your opening
- Insulated sill/threshold to help reduce drafts at the bottom of the door
- High-quality weatherstripping around the perimeter of the door
- New exterior brickmould or cladding for a clean, finished look
When Great Northern Home Exteriors installs your new Dorplex entry door, we remove the old frame and install a complete, insulated system — not just a new slab into an old opening.
Our Entry Door Installation Process
We take the time to install your new Dorplex entry door properly so it looks great and operates smoothly from day one.
- Careful removal of your existing door, frame, and trim
- Inspection and preparation of the opening, including shimming and leveling
- Installation of the new Dorplex door system with frame, sill, and weatherstripping
- Foam insulation around gaps to help reduce drafts

Dorplex Entry Door Warranty
