How far ahead should I book window installation if I want them done in spring?

For spring window installation in Ottawa, you should book 2 to 4 months in advance — meaning January through February is the ideal time to secure your spot for April or May installation.

Spring is one of the busiest seasons for window and door installers in Ottawa. Homeowners who waited out the winter want work done before summer, and contractors fill up quickly. The most experienced installers with strong reputations tend to book out the fastest, so waiting until March or April often means settling for whoever is still available — or pushing your project into summer.

Booking in January or February gives you several advantages. You'll have more flexibility to choose your preferred installation dates, and you'll have time to properly select products without feeling rushed. Custom or specialty windows — like bay windows, bow windows, or non-standard sizes — can take 4 to 8 weeks to manufacture and deliver, so early booking ensures your windows arrive on time for your scheduled install date.

There's also a practical financial benefit to booking early. Some installers offer off-season pricing or promotions during the winter months when demand is lower. Locking in your project in January or February can sometimes save you money compared to booking during the spring rush.

If you're considering energy efficiency upgrades like triple-pane or ENERGY STAR certified windows, early booking also gives you time to explore the Canada Greener Homes Grant and ensure your chosen products meet eligibility requirements before installation day.

If you already know you want spring installation, now is a great time to reach out. Ottawa Window Pros offers free consultations and can walk you through product options, timelines, and pricing — so you're not scrambling when the weather warms up.
