Sunroom FAQ for Winnipeg, MB Homeowners

A three-season room is an aluminum-frame glass or screen room, not heated or insulated to house standards, used from spring to fall. A four-season room is an insulated addition with thermal glass, a frost-protected foundation and its own heat, used all year. In Winnipeg, the four-season room is the one families use most.

Typical installed ranges in the Winnipeg area in 2026: patio covers $6,000 to $14,000; screen rooms $8,000 to $20,000; three-season glass rooms around 12 by 12 feet $30,000 to $60,000; four-season rooms the same size $60,000 to $100,000 or more; larger custom additions $100,000 to $150,000 and up. Your exact quote follows a site visit.

Often, yes, for a screen room or a three-season room, if the deck is sound and its footings are below frost. A four-season room needs frost-protected footings or a slab, so it usually gets a new foundation. We check the deck at the site visit.

A four-season room always needs a building permit, drawings and engineering. Most three-season rooms do as well, and any electrical work needs an electrical permit. Rules differ between the City of Winnipeg and the rural municipalities, so we confirm them for your address as part of the quote.

A four-season room gets its own heat sized to the glass area: electric baseboards, a cold-climate ductless heat pump that also cools in summer, or a tie-in to the furnace when the ductwork allows. Thermal, low-emissivity glass does most of the work. Three-season rooms are not heated.

A glass roof can be. Most Winnipeg rooms get a solid insulated roof with optional skylights, low-emissivity glass that rejects summer heat, and a ceiling fan or the heat pump for cooling. Orientation matters: a west-facing room takes the most afternoon heat.

Materials take four to eight weeks to arrive after the quote is signed. On site, a screen room or three-season room is usually finished in one to two weeks and a four-season room in four to eight weeks. Most Winnipeg rooms are installed May to October; design and permits are best done in winter.

A well-built four-season room is counted as living space by appraisers and adds value in line with other additions. A three-season room is not counted as living space, but it is one of the features buyers remember. Either way, a room built for the climate holds its value; one that leaks does not.

Yes. We serve the broader Capital Region including Headingley, Oak Bluff, East St. Paul, Niverville, Steinbach, and Selkirk, alongside Winnipeg. The deeper lots outside the city are often the easiest places to fit a larger room.

Yes. The foundation, structure and installation are warranty-backed, and the glass and panel systems carry their manufacturer's warranty. We explain the specific coverage as part of your written quote.
