Bow Windows Installation & Replacement

A bow window is a multi-panel window that curves outward from a home’s exterior wall, typically built from four or more equally sized panels arranged in a gentle arc. Unlike a bay window, which uses three angled panels for a sharper, more angular projection, a bow window’s rounded shape lets in light from a wider range of angles and creates a softer, more panoramic sightline.

1st Choice Home Solutions provides custom bow window installation and replacement for homeowners across London, Ontario and throughout Middlesex, Lambton, and Elgin County, using Canadian-manufactured vinyl frames built for our local climate. Bow windows are a popular upgrade for living rooms, dining areas, and front-facing walls, where the added curve creates a brighter, more spacious feel and a distinctive architectural focal point.

What Is a Bow Window?

A bow window is a curved, multi-panel window unit that projects outward from an exterior wall, most often built with four, five, or six equally sized panels arranged in a gentle arc. Because every panel is the same size, a bow window creates a smooth, rounded profile rather than the sharper angles of a bay window.

Bow Windows vs Bay Windows

Bay windows typically use three panels — a large fixed centre window flanked by two smaller angled side windows — while bow windows use four or more equally sized panels curved into a wider arc. Bow windows generally let in light from more directions and create a larger interior shelf, while bay windows are often the simpler, more budget-friendly option to install. 1st Choice Home Solutions installs both styles across London and Southwestern Ontario, so if you’re weighing a bow window against a bay window, our team can help you decide which shape best fits your room.

Why Choose Bow Windows?

Bow windows offer both a design upgrade and a functional one, and homeowners across London and area choose them for a mix of these reasons:

Curved, Panoramic Design: Bow windows feature 4 or more connected window panels in a soft, rounded angle — offering expanded views and boosting curb appeal.
Let in More Light: The graceful arch of bow windows captures sunlight from multiple directions, brightening up your interior space throughout the day.
Flexible Functionality: Choose a combination of fixed and operating windows to enjoy airflow without sacrificing the wide-angle view.
Energy Efficient & Insulated: Our premium vinyl frames outperform traditional wood and aluminum by preventing drafts and improving home comfort.
Adds a Focal Point & Curb Appeal: A bow window’s outward curve creates a distinctive architectural feature that stands out from the street, often becoming the visual centerpiece of a front-facing room.

How We Install Your New Bow Windows

Every bow window project starts with a free, in-home consultation. Our team measures your existing window opening, walks you through fixed-and-operating panel combinations, and shows you frame, grille, and glass options in person, before providing a written quote.

Because a bow window spans a wider opening than a standard window, our installers assess your wall structure during your consultation and confirm what framing or support your specific installation needs before your windows are built to order.

Frequently Asked Questions About Bow Windows

Do bow windows open for ventilation?

Yes. Bow windows can be built with a mix of fixed and operating panels, so you can choose airflow without giving up the wide-angle view. Many homeowners keep the centre panels fixed for an unbroken view and make the side panels operable for ventilation.

Do bow windows need extra structural support?

Sometimes. Because a bow window spans a wider opening than a standard flat window, installation can involve additional framing or support beneath the unit. 1st Choice Home Solutions’ installers assess your home’s structure during your free consultation and outline exactly what your installation will require.

How much does bow window installation cost?

Cost depends on the number of panels, the size of the opening, your glass and grille choices, and whether any extra structural support is needed. Because every home is different, 1st Choice Home Solutions provides a free, no-obligation quote based on your specific project.

What rooms work best for a bow window?

Bow windows are most popular in living rooms, dining rooms, and other front-facing rooms, where the wider curve creates a bright focal point and extra interior shelf space. They also work well anywhere you want a panoramic view of the yard or street.
