Choosing the Right Entry Door Material for Your Home
Not every entry door serves the same purpose. Whether you’re replacing an older front door or completing a newer build, the right material comes down to security, energy performance, and how the door fits your home’s exterior style.
Steel Entry Doors
- High-impact strength with excellent resistance to forced entry
- Smooth, clean panel design with sharp architectural lines
- Cost-effective option without sacrificing durability
- Ideal for most front entrances in both traditional and modern homes
Fibreglass Entry Doors
- Realistic woodgrain appearance without ongoing maintenance
- Resists dents, moisture, and warping over time
- Strong insulation values for consistent indoor comfort
- Great choice for style-focused upgrades and custom finishes
Not sure which option fits your home best? We’ll walk you through the differences, show material samples, and help you choose an entry door that balances curb appeal, comfort, and long-term value.
Adding Light, Privacy, and Character with Decorative Door Glass

The right design can brighten your entryway, enhance security, and add personality without overpowering the exterior. Our Dorplex steel and fibreglass entry doors offer a wide selection of glass styles suited to both modern and traditional homes.
- Frosted or satin glass – lets in soft daylight while preserving privacy

Whether you’re aiming for a bold statement or a subtle, refined entrance, we’ll help you choose decorative glass that fits your home’s architecture, lighting needs, and personal style.

Why Full-Frame Door Replacement Matters for Long-Term Performance
When an entry door is replaced properly, the work begins at the framing — not the surface. That’s why our installations focus on a full-frame replacement process, allowing us to address alignment, sealing, and structural support before the new door is ever secured in place.
This approach is especially important for older homes and properties exposed to wind, moisture, and seasonal temperature swings, where shortcuts can lead to drafts, sticking doors, and premature wear.
- Remove the existing door system, including frame and exterior trim.
- Inspect the rough opening for moisture damage or framing movement.
- Position the new Dorplex door frame level and square.
- Shim and secure the frame at key structural points.
- Seal the perimeter using low-expansion foam to limit air movement.
- Install new brickmould and exterior trim for a finished look.
- Apply exterior-grade caulking and complete final hardware adjustments.
What a Full-Frame Installation Solves
Installing a new door inside an older frame can hide issues such as out-of-square openings, air leakage, and compromised sealing. A full-frame replacement gives us access to correct these problems before the door is finalized.
The result is better door alignment, smoother operation, and reliable performance year after year.
Built to Handle Exposure, Age, and Everyday Use
Entry doors in this area face a combination of strong winds, temperature swings, and seasonal moisture that can quickly expose weak installation work. Drafts, shifting, and water intrusion are especially common in older homes where original framing has moved over time.
In many cases, simply swapping the door slab isn’t enough. Frames that are out of square or no longer sealed properly require a full-frame replacement to correct alignment issues and restore long-term performance. This allows us to remove the existing frame, reset the opening, and seal it correctly using low-expansion foam and factory-applied weatherstripping.
Whether the home is a traditional brick build or a newer residential layout, every Dorplex steel or fibreglass entry door we install is matched to the structure, exposure, and daily use of the entryway. The result is a quieter interior, improved comfort, and a secure entrance built to perform year after year.
What Happens on Installation Day — Clear Steps, No Guesswork
On installation day, our focus is on delivering a smooth, respectful experience from the moment we arrive. Your entry door replacement is handled with care, clear communication, and attention to your home — not rushed work or unnecessary disruption.
Before any removal begins, we review the plan with you and take steps to protect floors, walls, and nearby finishes so the process stays clean and organized throughout the day.
- ✓ Careful removal of the existing door, frame, and exterior trim
- ✓ Inspection of the opening and sill to identify moisture or structural concerns
- ✓ Precise installation of your new Dorplex entry door system so it sits level and operates smoothly
- ✓ Perimeter sealing using low-expansion foam to limit drafts and air movement
- ✓ Installation of new exterior brickmould and interior casing for a finished, professional appearance
- ✓ Final hardware setup, weatherstripping check, and operation testing, followed by a complete cleanup
Before we leave, we’ll walk you through the finished front, garden, or French door, answer any questions, and confirm everything opens, closes, and locks properly — so you’re fully comfortable with the installation.

Entry Door Installation Questions Homeowners Often Ask
How long does a typical entry door installation take?
Most entry door installations are completed in a single day. Our crew removes the existing unit, installs your new Dorplex door system, seals the opening using low-expansion foam, completes exterior trim work, and performs a full cleanup before leaving.
Do you install garden doors and French door systems?
Yes. We install steel and fibreglass entry doors, including garden doors and French door systems, sized specifically for your opening. Each door is installed using a wood frame, factory-applied weatherstripping, and low-expansion foam for a tight, reliable seal.
Can the door colour and exterior trim be matched to my home?
Absolutely. We offer a range of factory-applied colours, realistic woodgrain finishes, and colour-matched exterior capping so your new entry door blends cleanly with your home’s brick, siding, and exterior details.
Will replacing my entry door help reduce drafts?
Yes. Modern entry doors feature insulated cores, high-quality weatherstripping, and are installed using a proper full-frame replacement method. This helps reduce drafts and improves comfort, especially in homes with older or shifting door frames.
