Upgrade your home's security, energy efficiency, and curb appeal. We install beautiful, high-performance steel and fiberglass doors across Grimsby, Hamilton, and Burlington.
Make a stunning first impression. Our front entry doors come in heavy-duty steel or elegant fiberglass designed to mimic real wood grain without the maintenance. Highly insulated and extremely secure.
Seamlessly connect your indoor and outdoor living spaces. Our patio sliding doors feature easy-glide tracks, maximum glass area for natural light, and premium thermal seals to keep winter drafts out.
Add a touch of classic elegance. Traditional swinging French doors provide wide access and brilliant architectural detail, paired with sophisticated multi-point locking hardware.
A door is more than an entry point; it's the centerpiece of your homeβs aesthetic. Apex offers thousands of customization combinations across Grimsby and Hamilton.
Boost natural light and curb appeal with frosted, textured, or stained glass inserts and matching sidelight panels.
Choose from factory-applied, scratch-resistant paints in everything from classic Iron Ore to modern Slate Grey and vibrant Navy.
Add architectural height with overhead transoms and heavy-duty, thermally-broken aluminum sills for maximum draft protection.
We don't settle for standard deadbolts. Our premium exterior doors can be fitted with advanced multi-point locking systems that grip the doorframe at three separate points, virtually eliminating the risk of forced entry while ensuring an airtight seal against Niagara's heavy winds.
Don't wait until your home is exposed to the elements or security is compromised. Look for these warning signs.
If you feel cold air near the floor or see light peaking through the frame, your seals have failed. A new fiberglass door can pay for itself in energy savings.
Doors that are difficult to open or close usually have structural frame damage or warped materials, creating a major safety hazard in emergencies.
Peeling paint, rusted steel, or soft spots in wood-core doors are indicators that moisture has penetrated the core. Replacement is the only permanent solution.

We exclusively install doors engineered to survive Canada's climate extremes, meaning zero warping, cracking, or severe expansion.
The ultimate choice for structural strength and security. Steel doors offer smooth finishes perfectly suited for modern aesthetics and boast massive insulation cores.
The gold standard for durability and beauty. Fiberglass resists denting and scratching, requires virtually no maintenance, and can be stained to mimic the exact texture of rich mahogany or oak wood.
Every home shifts over time. Our experts measure your doorframe down to the millimeter to ensure an airtight, perfectly level custom fit before manufacturing begins.
We don't just hang a door. We inspect the underlying rough opening, repair any wood rot, and inject high-density insulating foam deep into the frame gaps.
Your home will never be left exposed. Our removal and installation process happens entirely in a single day, followed by a meticulous clean-up and hardware testing.
Costs vary based on material (steel vs. fiberglass), glass inserts, framing needs, and hardware. Our basic steel entry doors are highly affordable, while custom fiberglass configurations represent a premium investment. Contact us for a free, exact quote.
