A clean exterior upgrade in beautiful Niagara-on-the-Lake 🍷🏡

We recently completed this project featuring:
✔️ New shake siding feature wall
✔️ Custom arched picture window installation
✔️ Fresh modern contrast with clean white trim
✔️ Improved natural light and curb appeal

The new arched window completely changes the look of this home and creates a bright, open feel inside while the shake siding adds texture and character that really stands out.

Projects like this are why custom exterior work makes such a huge difference — especially on unique homes where standard layouts just don’t cut it.

Just wrapped up this window upgrade in St. Catharines 👇

We installed a new black bay window out front and replaced older basement slider windows to tighten up the home and improve efficiency.

A lot of homes around St. Catharines still have original basement windows that let in drafts and moisture. Upgrading them makes a noticeable difference right away — especially with humidity and temperature changes.

The new bay window also gives the front of the home a completely updated look 👌

If your windows are foggy, drafty, or starting to show their age, it might be time to take a look.

New Entry Door & Window Upgrade in St. Catharines 🚪🪟

Just wrapped up another clean install right here in St. Catharines — and this one made a huge difference in both curb appeal and comfort.

✔️ Brand new steel entry door system
✔️ Added storm door for extra protection & airflow
✔️ Installed a large front picture window with double hungs for better light + ventilation

This setup gives the homeowner:
• More natural light in the front of the home

A lot of homes in St. Catharines still have older front windows like this — once they’re upgraded properly, the difference is night and day.

Thinking about installing your own siding? 🏠

A small repair like replacing one damaged panel may be manageable for some homeowners, but larger siding jobs often become much more complicated than they look.

One of the most common mistakes we see is siding being nailed too tightly, which can cause buckling and uneven lines as temperatures change through the seasons. We also often see messy trim work around windows that leaves the exterior looking unfinished.

In our latest blog, we break down when a DIY repair may be okay and when it’s smarter to bring in a professional siding installer.

✨ Another clean exterior upgrade completed in St. Catharines!

We recently finished installing new white eavestrough, fascia, and soffit, giving this home a fresh, clean roofline and improved protection against water runoff.

Not only does it brighten the exterior, but it also helps protect the home from moisture issues while improving curb appeal.

If your existing gutters are sagging, leaking, or your fascia and soffit are starting to show wear, now is a great time to upgrade.

A window warranty should protect more than just the product itself.

Before choosing a contractor, it’s essential to understand the differences between manufacturer coverage, workmanship warranty, WSIB protection, and who will be available to answer the phone if service is ever needed later.**

We just published a new homeowner guide that breaks it all down in plain language.

Read it here 👇

At Great Northern Home Exteriors, every installation includes our **5-Year Workmanship Warranty**, and we’re always here if you need service.

Not every window problem is caused by the window itself — sometimes it comes down to **poor installation**.

If your window feels drafty, doesn’t lock properly, sticks when opening, or shows signs of water getting in, the issue may be how it was installed.

We just published a new homeowner guide:

**How to Tell If a Window Is Installed Incorrectly**

In this article, we break down what to look for, including:
✔ windows not sitting square
✔ locks not lining up
✔ messy or missing exterior finishing
✔ water infiltration concerns
✔ signs a measurement mistake may have been covered up

As installers, we’ve seen situations where a poor fit ended up causing bigger issues inside the wall over time.
