Give Your Herbs the Best Seat in the House
Most windows just sit in their opening and let light through. A garden window does more than that. It steps outward from the wall, catches sunlight from three angles instead of one, and gives you a little ledge to set plants, herbs, or whatever you want to keep close to the sink.
At Gerry's Roofing & Siding, we've been installing windows and doors for Hamilton homeowners since 1980, and we've completed more than 30,000 exterior projects across the region. For garden windows, we install vinyl units from Del Windows & Doors, a Canadian manufacturer, and every project comes with our Transferable Lifetime Workmanship Guarantee. It’s time to add sunlight, fresh greens, and architectural character right where your kitchen needs it most.

More Than a Flat Pane of Glass
Picture a standard window, then imagine it pushed out from the wall by four to fourteen inches, with glass panels on the front and sides and a sloped pane up top. That's a garden window, and the shape is what gives it its personality. Because the glass wraps around three sides, sunlight can reach the room from more directions throughout the day.
The shelf created by the projection gives you a spot for potted herbs or a few plants, and the added depth can make a kitchen wall feel more open, even if you haven't changed the room's footprint. For older Hamilton homes with kitchens that face a shaded side of the property, this kind of window can be the difference between a room that feels closed off and one that finally gets some natural light. A small change in the window can shift how the whole room feels.
The Details That Make It Yours
We source these windows through Del Windows & Doors, a manufacturer we've worked with for years on window and door installations throughout Southern Ontario, and their vinyl construction makes a lot of sense for a window sitting right above a busy kitchen sink. It won't need repainting, it withstands the humidity from cooking in the room, and it handles Hamilton's temperature swings with little trouble.
Your opening and your goals for the window both play a role in which features make sense:
Frame Sizes: We can adjust the width and projection depth to suit your existing opening and the room it sits in. That level of customization helps the window look as if it were planned into the kitchen from the start.
Operable Side Vents: Side panels can crack open to release steam or trapped heat. This comes in handy on busy cooking days when your kitchen could use a quick way to clear the air without turning on a fan.
Low-E Glass: A coating that helps manage heat transfer, keeping the room cooler in summer and warmer in winter. It also reduces how much your HVAC needs to run to keep that part of your kitchen comfortable.
Frame Colours: A selection of colours to help the new window blend in with your siding and trim. Picking a shade that complements the rest of your exterior keeps the addition from standing out as a replacement.
We're also certified with the manufacturers we install, which gives our experts hands-on training on the products themselves. You pick the details, and we’ll make sure they work together.

A Guarantee That Goes the Distance
Installing a garden window takes more than putting glass in an opening. The framing that supports it, the flashing that protects it, and the finish work that rounds out the project all factor into how long this type of window performs.
That's why every installation from Gerry's Roofing & Siding comes with our Transferable Lifetime Workmanship Guarantee. You get workmanship coverage for as long as you own the home, and if you decide to sell, that coverage can transfer to the next owner for up to 20 years. We also offer payment plans for homeowners who'd rather manage this as a monthly expense.
Coverage that outlasts a sale gives you one less thing to worry about down the road. That peace of mind is part of what you're getting alongside the window itself.
What It Takes to Build Beyond the Wall
Because it extends beyond the exterior wall and needs proper support beneath it, a garden window requires a bit more planning than a flat replacement window.
Here's how we'll approach your project from beginning to end at Gerry’s Roofing & Siding:
Clearing the Way
Our crew will start by removing your current window, working slowly enough to avoid unnecessary damage to the surrounding wall. This step lets us see the true condition of the opening and framing behind it before anything new goes in.
Preparing the Opening
Since garden windows project outward from the wall, we'll assess the framing and make any necessary adjustments to support the extra load. This might mean reinforcing existing studs or adjusting the header above the opening, depending on what your home needs.
Sealing Out the Weather
Once the opening is ready, our technicians will install flashing and seal each point where the window meets your exterior wall, paying particular attention to the top and sides of the unit. This is where rainwater and melting snow need a safe place to drain.
Finishing the Details
After the window is set, supported, and sealed, we'll complete the casing, trim, and any surrounding exterior work the project calls for. Our goal is for the finished window to look like it's always been part of your kitchen rather than an obvious addition.

Frequently Asked Questions
Both project outward from the wall, but a bay window is typically larger and can create an alcove inside the room. A garden window has a smaller footprint, a built-in ledge, and glass on several sides, which is part of why it works so well over a kitchen sink.
Often, yes. Older homes sometimes need framing adjustments before a projecting window can be installed correctly, which is exactly why we inspect the opening first. Our process accounts for whatever support and sealing your specific home needs.
The cost depends on the size of your opening, the configuration you choose, glass options, and any framing work needed to support the projection. Once we've taken a look at your window and heard what you're hoping for, we'll put together a quote that reflects your project.
Many configurations include operable side vents, which are handy in a kitchen when you want steam or cooking heat to escape. What's available depends on the size and style you choose.
