Window cleaning in Calgary typically starts at $149 for exterior-only cleaning. At N3ST we price by the pane — exterior cleaning is $9 per pane, and exterior plus interior is approximately $16 per pane. French or divided windows are an additional $3 per pane. If you book window and gutter cleaning together you save $40. Use our free quote tool to get an exact price for your home in under a minute.

For most Calgary homes, we recommend cleaning your windows 2 to 4 times per year. Calgary's dry climate means dust and mineral deposits build up quickly, especially in spring after the snow melts and in fall before winter sets in. Our most popular plan is quarterly — four cleans a year keeps your windows consistently clear and saves you $75 per visit compared to one-off pricing.

For exterior-only cleaning you don't need to be home — we just need access to the outside of your home, all windows shut, and an outdoor water tap accessible. For interior window cleaning someone does need to be present. Either way we send automated text confirmations and reminders so you're always in the loop.

We offer a 7-day rain guarantee on all window cleaning services. If it rains within 7 days of your clean and your windows are left with spots or streaks, we'll come back and re-clean at no charge. Calgary weather is unpredictable — we think that risk should be on us, not you.

We operate spring through fall for window cleaning in Calgary — typically April through October. Calgary winters make exterior window cleaning impractical due to freezing temperatures and ice. However, we do offer permanent LED light installation year-round, which is actually best installed in the fall before the busy holiday season. We'll reach out ahead of each season to get you scheduled early.

Most residential window cleaning jobs in Calgary take 1 to 3 hours depending on the size of the home and whether you've booked exterior-only or exterior plus interior. Adding gutter cleaning typically adds another 30 to 60 minutes. We'll give you an estimated time window when you book and send a text when we're on our way.

Permanent LED lights are architectural lighting installed once along your roofline and controlled year-round by a smartphone app. Unlike traditional Christmas lights, they stay up permanently and can display any colour or pattern — holiday lights in December, green and white for Canada Day, or just a warm white glow year-round. Pricing varies by home size. Get a custom quote here.

For exterior cleaning: make sure all windows are closed, move any fragile outdoor items away from windows, and ensure your outdoor water tap is accessible. For interior cleaning: remove any valuables or breakables from windowsills, and clear a small workspace around each window. We'll take care of the rest.
