Now THIS is a siding transformation!

We replaced the home’s dated Tudor-style stucco and wood exterior with new Brownstone board-and-batten siding—and the difference is incredible.

The vertical siding gives the home a cleaner, more modern appearance while complementing the existing red brick perfectly. The Brownstone colour also works beautifully with the dark brown soffit, fascia, eavestrough and exterior details.

Swipe through to see the before-and-after transformation from every angle.

Thinking about replacing your siding? Great Northern Home Exteriors provides professional siding installation throughout the Niagara Region using our experienced in-house crews.

Why can two entry doors that look similar have very different installed prices?

Because homeowners aren’t buying only a door slab. The complete project may include:

🚪 Steel or fibreglass construction
🪟 Decorative glass, sidelites or a transom
🔐 Handlesets, locks and hardware
📐 Full-frame removal and installation
🏠 Interior trim and custom exterior capping
🛠️ Work required around the existing opening

Our newest guide explains how entry door pricing works in Niagara—without confusing “starting prices” or unrealistic one-size-fits-all numbers.

How much does eavestrough installation actually cost in Niagara? 🤔

The answer depends on more than the number of feet around your roof. System size, roofline complexity, downspouts, fascia condition, soffit work, and gutter protection can all affect the quote.

Our newest homeowner guide explains:

✓ 5-inch versus 6-inch eavestrough
✓ Repair versus complete replacement
✓ What should be included in your estimate
✓ When soffit, fascia, or gutter guards affect the cost
✓ Why the lowest quote may not provide the best value

🏡 Why do so many older Welland homes eventually need new windows?

Not every window problem is obvious. Drafts, foggy glass, condensation, rising energy bills, and windows that are difficult to open can all be signs that it's time for an upgrade.

We recently put together a new guide explaining why many older Welland homes experience these issues and what homeowners should look for before deciding between repair and replacement.

If you're thinking about replacing your windows, we hope you'll find it helpful.

🚪 Think a door installation is just swapping one door for another?

Most homeowners never see what happens behind the trim or under the sill—and that's exactly where the quality of an installation is determined.

A professional entry door installation should include:

✅ Sill reinforcement and sealing
✅ Frame insulation
✅ Exterior capping
✅ Interior trim finishing
✅ Hardware installation
✅ Proper weatherproofing

We've pulled back the curtain and explained what should be included in every quality installation, along with the shortcuts that can cost homeowners thousands in future repairs.

If you're planning to replace your front door, this guide is worth five minutes of your time.
