The View Can Stay. The Drafts Can Go.

Windows don't usually fail all at once. They give out gradually, through years of temperature swings, moisture, and constant use, until you notice a draft that wasn't there before or a lock that doesn't quite catch. That kind of decline often shows up in Hamilton homes, especially those that have been through a few winters and summers without an update. 

Once seals or frames start failing, replacing them can restore both the room's feel and the exterior's appearance. Gerry's Roofing & Siding has served Southern Ontario homeowners since 1980, with window replacement among our most common projects. Say goodbye to cold air seeping in and high energy bills, and hello to windows made for Hamilton weather.

More Than One Way to Frame a Room

Not every window in your house has to do the same job. A bedroom might call for something that opens to improve airflow, while a living room might be better served by an uninterrupted view. That’s why we install a full lineup of Del Windows & Doors products, so you have plenty of room to mix styles to suit each space.

Vinyl Windows

Vinyl is where many window projects start, since the frames withstand freeze-thaw cycles without warping, cracking, or fading. They also need little upkeep beyond an occasional wipe-down, which counts for a lot during busy seasons when window care isn't top of mind.

Awning Windows

Awning windows hinge at the top and swing outward from the bottom, providing ventilation without swinging into the room. That design makes them a solid option for bathrooms, basements, and other spots where room is tight and a wide-opening window wouldn't work.

Casement Windows

Casement windows swing outward from a side hinge using a crank, opening the entire sash for maximum airflow when you want it. When closed, the sash sits flush against the frame, giving you an uninterrupted view without a center bar cutting through the glass.

Picture Windows

When the goal is more natural light, picture windows deliver. Because they're fixed in place, there's no hardware, no crank, and no sash to interrupt the glass from top to bottom. That's why homeowners often choose them for rooms where the view outside is worth showing off.

Bay Windows

Bay windows extend beyond the exterior wall, drawing in light from multiple angles rather than a single flat pane of glass. That projection creates extra room inside for a bench, shelf, or reading nook. Bay windows also tend to be a focal point from the street, adding architectural interest.

Sliding Windows

Sliding windows move side to side along a track instead of swinging open. That horizontal motion makes them practical for larger openings, where furniture or landscaping limits how far a window can extend. Operation also remains consistent because there are fewer moving parts.

Double-Hung Windows

Sliding windows move side to side along a track instead of swinging open. That horizontal motion makes them practical for larger openings, where furniture or landscaping limits how far a window can extend. Operation also remains consistent because there are fewer moving parts.

Garden Windows

Garden windows push outward, forming a small glass box. They're popular above kitchen sinks, where the extra light gives an otherwise plain wall an unexpected boost. Homeowners often use the interior shelf for small plants that need sun but don't have anywhere else to sit.

Hopper Windows

Hinged along the bottom and tilting inward from the top, hopper windows open in a way that takes up minimal room inside. That compact design still allows for decent airflow, and they’re a top choice for smaller openings where privacy and ventilation both come into play.

Architectural Windows

Some openings call for something beyond a standard rectangle, and that's where architectural windows come into their own. These bring unique shapes into play, such as arches, half-circles, and trapezoids, highlighting entryways, rooflines, and other standout features.

Ready for Whatever the Forecast Brings

Many of the windows we install come from Del Windows & Doors, a Canadian manufacturer that designs its products around homes like the ones here in Southern Ontario. That detail matters when a single window has to handle brutal winters, sticky summers, and everything in between.

We’ll help you pick styles and exterior colours that pair well with your siding, brick, roofing, and trim, instead of treating every window as interchangeable. Gerry's Roofing & Siding is also certified to install the products we work with, which means every installation meets the standards set by those manufacturers.

You can find more on the product line over on our Del Windows & Doors page. New windows deserve a manufacturer that understands the conditions they'll face season after season.

When Your Windows Start Falling Behind

An old window doesn't automatically need replacing just because it's old. What tells you more is how it's functioning today. You might be due for new windows if you're dealing with:

  • Fog or condensation trapped between the panes

  • Drafts you can feel even with the window shut tight

  • Windows that stick, jam, or won't lock properly

  • Warped frames, visible damage, or staining around the opening

  • One or two rooms that never seem to keep pace with the thermostat

Some problems show up right away, like a cracked frame or a lock that no longer catches. Others creep in slowly enough that you stop noticing them altogether. If any of these sound familiar, it's worth having someone take a look at them before they turn into a bigger repair.

What to Expect During Your Project

Replacing windows doesn’t need to feel overwhelming. Our process is built around clarity, pacing, and making sure you’re informed about each step before we begin.

We’ll kick everything off with a conversation.

An in-home visit gives us a chance to assess your existing windows, take measurements, discuss what’s bothering you, and learn about your goals.

We’ll help you narrow the choices.

With a variety of window styles and more than 20 exterior colours, it can feel like a lot at first. We take a long list of possibilities and turn it into a short list you can feel good about.

Installation is handled carefully.

Our technicians remove your old windows with care and install the new ones, paying close attention to sealing, trim, and finish.

We’ll review everything together.

Before wrapping up, we’ll walk through the work with you, make sure each window opens and closes properly, and answer any last questions you may have.

Two Layers of Coverage for the Years Ahead

A manufacturer's warranty and an installation guarantee protect two separate parts of your project. Del Windows & Doors backs its products under the applicable manufacturer's terms, and Gerry's Roofing & Siding backs the labor that installs those products in your home.

Our Transferable Lifetime Workmanship Guarantee covers the original homeowner for the lifetime of the installation. If you sell the home, that coverage can transfer to the next owner for up to 20 years. Knowing who stands behind the product and who stands behind the labor gives you two forms of protection instead of one.

Breaking Up the Cost of an Upgrade

Replacing one window and replacing every window in the house call for very different budgets. For larger projects, Gerry's Roofing & Siding offers payment plans that let you spread the cost out instead of paying the full amount upfront.

Taking on more windows shouldn't mean taking on more financial pressure all at once. Ask about our current financing options when you request your free estimate, or visit our dedicated payment plans page for more information.

Frequently Asked Questions

It depends on the project's scope and whether the opening's size or structure is changing. Your consultant will go over what applies to your specific project during your in-home consultation.

Timelines vary based on how many windows you're replacing, the styles you've chosen, and the condition of the existing openings. We'll go over the expected schedule with you before installation starts.

Newer windows can cut down on drafts and heat loss, especially if the ones you're replacing have failing seals or worn-out frames. How much of a change you'll notice depends on their current condition and the rest of your home's exterior.

Yes! We serve communities within about 45 minutes of Hamilton, including Ancaster, Dundas, Stoney Creek, Waterdown, Burlington, Oakville, Grimsby, and Brantford, along with several others nearby. Check out our service area page to confirm coverage at your location.

Get Ahead of Failing Windows

Perhaps there's one window you've learned to work around, or maybe your whole house isn't keeping heat the way it used to. Or maybe the originals have simply reached the point where new ones make more sense than another repair.

Either way, your home deserves windows that don't ask for a workaround. Contact Gerry's Roofing & Siding to request a quote for window replacement in Hamilton.
