Learn More About the Windows We Offer
If you’re searching for a “window company near me,” you want one with several options. If you’re unsure about what you need for your windows, the experts at BestCan Windows & Doors help you choose from the following and more.
Double-Hung Models Improve Ventilation Control

These windows feature two sashes, allowing you to open them from either the top or the bottom. They’re a popular choice because they provide more nuanced control over ventilation. They also tip inward, making them easier to clean, even on the top floor.
You’ll pay a premium price for these windows in Ottawa, which feature a more modern look. Double-hung windows also require a little more maintenance and are more vulnerable to developing leaks as they age.
Single-Hung Options Fit Well With Classic Home Styles

We’re the window installation company in Ottawa that suggests this version for homes on a budget. Their traditional design complements homes that have maintained a classic style. They also keep their energy efficiency longer because they have fewer moving parts.
You’ll find single-hung windows slightly harder to clean on the upper floors. They only open in one direction, which limits your ventilation control.
Casement Models Offer European Style and Increased Safety

Casement windows are popular in Europe and come in many forms. They use a lever or crank to open outward, either vertically or horizontally. You can only open them from inside the home, making them among the safest and most secure options.
Awning Windows Provide Ventilation in Rainy Climates

These models are similar to casement windows, but they only have a hinge at the top. When you open them, they resemble an awning windows. This significantly improves the building’s ventilation without putting it at risk of rain, snow, or other environmental factors.
Bay and Bow Varieties Impart Incredible Curb Appeal to Any Property

Bay Windows
You’ll immediately recognize these distinctive frames for their curved layout. They’re perfect for living rooms, as adding a bench provides the ideal spot for reading or a pet bed. They add distinctive curb appeal to every property that uses them.
The curve from a bay window is more pronounced than that of a bow model and features three panels instead of four or five. Our experts can convert any opening to accommodate these features.
Caring for Your Windows & Doors
A little regular care goes a long way toward keeping your windows performing at their best for decades to come.
- Clean regularly: Use a soft microfibre cloth with mild soap or glass cleaner monthly to keep frames and glass clear
- Inspect occasionally: Check frames each season for chips, cracks, or warping. Catching small issues early prevents bigger problems later
- Repair quickly: If you spot damage to a pane or frame, call us promptly; delays can lead to full replacement sooner than necessary
- Re-seal when needed: Worn weatherstripping and caulking cause drafts; resealing keeps energy bills low and your home comfortable
- Schedule annual maintenance: A professional inspection once a year helps your windows last up to 25 years
