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 Doors and Windows Helps Maintain Curb Appeal and Property Value
After we install windows in Ottawa, how can you care for them and help them last longer? If you want to make an excellent first impression, practice the following habits:
- Clean regularly: At least weekly, use a soft microfibre cloth and a mild soap or glass cleaner to remove smudges and debris.
- Inspect occasionally: Inspect your window frames for damage about once a month. Look for chips, cracks, or warping.
- Repair quickly: If you notice damage to the pane or frame, call for repairs. Delaying a solution could destroy your window and require full replacement.
- Seal when needed: Over time, the weatherstripping and caulking in a window can wear away, and you’ll feel a draft. Replacing the sealant keeps your energy bills low and your home comfortable.
- Maintain annually: Have a professional inspect your windows at least once a year. This helps the feature last up to 25 years.
