We are so happy with our garden door installation from Great Northern Home Exteriors. Clodette was great to work with. She is very professional and knowledgeable and provides a superior quality product. Clark, her installer, provides quality workmanship with great attention to detail. I would not hesitate to use GNHE again for any future window or door installations and would confidently recommend them to anyone looking to have any window or door installations.

Choosing Between Steel and Fibreglass Entry Doors
Every home has different priorities when it comes to durability, appearance, security, and long-term performance. For many local homeowners, deciding between steel and fibreglass entry doors comes down to how the door will be used and what conditions it needs to handle year after year.
Why Homeowners Choose Steel Doors
- Excellent strength and impact resistance
- Clean, smooth finish with crisp architectural lines
- More cost-effective than fibreglass options
- Well suited for both modern and traditional homes
Benefits of Fibreglass Construction
- Realistic woodgrain appearance without ongoing maintenance
- Resists dents, scratches, and moisture exposure
- Strong thermal performance for year-round comfort
- Handles temperature swings and seasonal weather changes well
Still weighing the pros and cons? We’ll walk you through real door samples, explain how each material performs in Niagara’s climate, and help you choose an option that fits your home’s style, budget, and long-term goals — so you feel confident before making a decision.
Decorative Glass Styles That Balance Light and Privacy
A new entry door can brighten your foyer and elevate curb appeal — but the right glass choice also affects privacy, natural light, and the overall look of your home. Our Dorplex steel and fibreglass entry doors are available with a wide range of modern and traditional glass designs.
- Frosted and satin glass that provides privacy without sacrificing daylight
- Wrought-iron glass inserts that add depth, character, and visual interest
- Clear glass with internal grills for a timeless, balanced appearance
- Mini-blinds between the glass for added control in garden and French doors
- Textured privacy glass well suited for side-lights and transoms
Whether you prefer a bold statement panel or a subtle frosted design, we’ll help you select a glass option that complements your entryway and fits the overall style of your home.
Finishing Touches That Complete Your New Entry Door
The right hardware and finishing details make a noticeable difference in how a new entry door looks and performs. We install high-quality components designed to last, operate smoothly, and complement your home’s style.
- Heavy-duty hinges that support smooth operation and long-term durability
- Decorative glass options available in clear, frosted, and privacy styles
- Energy-efficient weatherstripping that helps reduce drafts and moisture intrusion
- Quality knobs, levers, and deadbolts offered in modern and traditional finishes
- Custom-painted frames and brickmoulds matched to your home’s exterior colours
Our Full-Frame Entry Door Installation Process
A proper door installation starts with the opening, not just the slab. Our crews follow a full-frame replacement process to ensure your new entry, garden, or French door fits correctly and seals tightly against the elements.
- Remove the existing door, frame, and exterior trim down to the rough opening.
- Inspect the sill and surrounding framing for moisture damage or rot.
- Set the new Dorplex wood frame level, square, and plumb.
- Secure the frame using proper fasteners and shimming where required.
- Seal the perimeter with low-expansion foam and integrated weatherstripping.
- Install new exterior brickmould and trim for a clean, finished appearance.
- Apply exterior-grade caulking and complete final alignment adjustments.
Why Full-Frame Installation Matters
Reusing an older frame can lock in drafts, alignment problems, and worn sills. A full-frame replacement allows us to correct these issues and gives your new door system the best chance to seal properly and operate smoothly.
It requires more care on install day, but it delivers better long-term performance in homes exposed to seasonal temperature changes and moisture.
What to Expect on Entry Door Installation Day
When you book an entry door replacement with Great Northern Home Exteriors, we treat your home with the same care as our own. Our crew arrives on time, reviews the plan with you, and protects the surrounding area before work begins.
- Careful removal of the existing door, frame, and trim
- Inspection of the opening, sill, and surrounding framing for any concerns
- Precise placement of the new Dorplex door system so it is level, square, and plumb
- Sealing the perimeter with low-expansion foam and integrated weatherstripping
- Installation of new exterior brickmould and interior casing where required
- Final hardware check, weather seal review, and full cleanup before we leave
Before wrapping up, we’ll walk you through the finished front, garden, or French door, answer any questions, and confirm everything opens, closes, and locks smoothly.
