t
Sunbusters Windows & Doors recommends considering replacement if you notice drafts, cold spots, condensation between panes, sticking/hard-to-operate sashes, visible rot or damage, or rising heating and cooling costs. New windows can improve comfort, energy efficiency, and noise reduction.

How do I know if I need to replace my windows?

t
Sunbusters Windows & Doors can help you choose from popular residential styles like casement, sliding, picture, awning, bay/bow, and more—matched to your home’s look, ventilation needs, and budget.

What types of replacement windows can I choose from?

t
Yes. Modern windows often use insulated frames plus glass upgrades like Low‑E coatings and sealed insulated units. Sunbusters Windows & Doors will recommend the best glazing package for your home and Alberta’s climate.

Are replacement windows really more energy-efficient?

t
Lead time depends on custom manufacturing and scheduling. Once your windows are ready, many homes can be installed in 1–2 days (sometimes longer for larger projects). Sunbusters Windows & Doors will confirm timing during your estimate.

How long does a typical window replacement take?

t
In many cases, yes. Experienced installers use techniques to minimize heat loss during the swap. Sunbusters Windows & Doors will advise on seasonal considerations and the best approach for your home.

Can you replace windows in winter?

t
Either works. You can replace one window at a time if needed, or do a full-home upgrade for consistent appearance and performance. Sunbusters Windows & Doors can help you prioritize the windows that will make the biggest difference first.

Should I replace one window or the whole house at once?

t
Often, yes. New windows can improve curb appeal, comfort, and efficiency, features buyers care about. Sunbusters Windows & Doors replacements are a strong upgrade when renovating or preparing to sell.

Do new windows increase home value?

t
Yes. Sunbusters Windows & Doors provides warranty coverage on products and installation (details vary by product line and configuration). Your quote and paperwork will outline what’s covered.

Do Sunbusters windows include a warranty?

t
Remove blinds/curtains, clear furniture and breakables near the windows, and provide clear access inside and outside. Sunbusters Windows & Doors will share a simple prep checklist before your install.

How should I prepare my home for installation day?

t
Cost depends on window size and style, quantity, glass package upgrades (double vs. triple pane, Low‑E, etc.), access/installation complexity, and any required repairs. Sunbusters Windows & Doors provides a clear written estimate based on your exact project.
