Unfortunately, many homeowners make unnecessary mistakes when shopping for new windows. These mistakes can lead to energy loss, poor design choices, and wasted money.
Let’s ensure this doesn’t happen to you.

Purchasing new windows is an expensive decision. It’s not all about style or aesthetics: it is also about performance, price, and installation. Before you begin to shop for windows, learn how to avoid these five costly mistakes so you end up with the best windows for home use and a more energy-efficient, beautiful space.

Windows that receive poor ratings can leak heat in the winter and allow heat gain in the summer, raising your utility bill.

All windows aren’t created equal. Picking the wrong window styles for the home can lead to poor airflow, awkward layouts, or even water damage.
Here’s a breakdown of standard styles and when to use them:
| Window Style | Where It Works Best | Why Choose It? |
| Double-hung | Bedrooms, family rooms | Easy to clean, classic appearance |
| Casement | Kitchens, bathrooms | Cranks open, seals tightly |
| Picture | Living areas, stairwells | Bright, fixed for a scenic view |
| Bay/Bow | Front exterior walls | Elegant, adds space and value |
| Awning | Basements, bathrooms | Hinged at the top, suitable for rain |
| Slider | Patios, wide openings | Simple and space-saving |
Choose styles that match both the purpose of the room and the architecture of your home. Mixing a few can work, but stay consistent with trim and frame colour.
