Ottawa Sunrooms Built for the Full Four Seasons
Three-season comfort from April through November. Year-round living when you need it.
Three-season comfort from April through November. Year-round living when you need it.
Ottawa’s climate makes serious demands on any structure that bridges indoor and outdoor living. Winters regularly fall below -30°C. Summers push into the mid-30s. The shoulder seasons arrive without much notice — a week of April warmth followed by a late snowstorm, a September evening that drops twenty degrees by midnight. Standard construction doesn’t hold up to that range. That’s why every Craft-Bilt sunroom installed in Ottawa is engineered specifically for it.
We build three-season rooms and fully insulated four-season additions. A three-season room runs comfortably from early April through late November, handling the shoulder seasons that outdoor furniture can’t, and the cool evenings in May and October that send most people back inside. A four-season addition is a permanent, heated room — functional in January, comfortable in August, and indistinguishable from the rest of your home except for the glass walls.
Every installation is custom-fitted to your home. Whether your property is a century home in Old Ottawa South, a new build in Barrhaven, a semi-detached in Orleans, or a rural property in Manotick, the system is designed and installed for your specific foundation, roofline, and exposure. No off-the-shelf kits. No subcontractors working from a manual.
Three-season: Built for Ottawa’s long shoulder seasons. Insulated panels hold warmth through the cool spring evenings in May and the sharp fall mornings in October — well past the point a standard screen porch would be uncomfortable. Open-panel options keep things breezy during Ottawa’s humid July and August. The system closes tight when the temperature drops. Most Ottawa homeowners with a three-season room report using it from the first weekend in April to Remembrance Day or later.
Four-season: A fully insulated, climate-controlled room addition. Heatable through Ottawa’s January lows, coolable through the summer heat. Built with the same structural integrity as the rest of your home — this is not a porch enclosure or a temporary solution. It is a permanent addition to your living space, fully custom-fitted to your home’s footprint and finished to match.
Grand Vista is a Canadian-made aluminum sunroom system designed for the shoulder seasons — the months when Ottawa’s weather is interesting rather than extreme. Unlike fully insulated four-season systems, Grand Vista prioritizes connection to the outdoors: larger glass panels, a lighter structural frame, and a feel that puts you genuinely outside while keeping the wind and rain out. It’s the right choice for Ottawa homeowners who want to extend the season without building a full room addition. Custom-fitted to your home, backed by the same warranty as all Craft-Bilt installations.
Screen rooms are the most open-air option in the Craft-Bilt lineup. An aluminum frame fitted with insect screening gives you a bug-free outdoor space without blocking the breeze or the view. For Ottawa’s warm months, from May through September, a well-built screen room gets used every day.
Vista Windows are the stacking and sliding window systems that take a screen room further. Add them to an existing porch or screen enclosure to gain weather protection on rainy afternoons and cooler evenings, while still being able to open the space fully when the weather is right. They slide and stack to one side, leaving the opening completely clear.
Both options use the same durable aluminum framing as our structural sunroom systems. Available in White, Sand, Earthstone, and Black.
Retractable pleated screens drop down or retract across an opening on demand, giving you insect protection when you want it and an unobstructed view when you don’t. They work well on covered porches, under pergolas, and across large patio door openings where a fixed screen room isn’t practical.
In Ottawa, they’re popular for decks that face east or back onto green space, where mosquitoes and blackflies are heaviest in June and July. The pleated fabric folds away cleanly when retracted and holds its position reliably in light wind when deployed.
These install with minimal structural change to your existing porch or overhang. Available in manual and motorized operation.
A freestanding aluminum gazebo gives you a defined outdoor room without attaching anything to your home. The structure stands on its own footings, which makes it a good option for Ottawa properties where the deck layout or setback restrictions make an attached enclosure complicated.
The aluminum frame handles Ottawa’s snow load and won’t rust, rot, or need repainting. Roof options include solid aluminum panels for full shade and rain coverage, or polycarbonate panels that let diffused light through while keeping rain out.
Available in White, Sand, Earthstone, and Black frame finishes. Can be combined with screen panels or Vista windows for added enclosure.

Q1. Are Craft-Bilt sunrooms built for Ottawa winters?
Absolutely. Ottawa winters are no joke, and we build for them. Craft-Bilt sunrooms use heavy-duty aluminum frames that won’t rot, warp or crack through freeze-thaw cycles, and our double-pane glass options keep the space genuinely usable when it is minus 20 outside. Whether you want a three-season retreat or a four-season room you heat all winter, we have an Ottawa-ready option for you.
Q2. Do I need a building permit for a sunroom in Ottawa?
In most cases, yes. The City of Ottawa requires a building permit for sunroom additions, and the specifics depend on the size of the room, whether it attaches to your home, and your property’s zoning. We have worked with local homeowners through this process many times and are happy to walk you through what to expect before your project starts.
Q3. How long does sunroom installation take in Ottawa?
Every project is a little different, but the sunroom installation itself typically takes 2 to 3 days in Ottawa. That does not include any foundation work, deck construction, or site-specific preparation that may be needed beforehand. The bigger variable is lead time: spring and summer are our busiest seasons in your area and Eastern Ontario, so the earlier you book, the sooner you are sitting in your new sunroom. Get in touch and we will give you a realistic timeline for your project.
