Serving Winnipeg & the Capital Region
Three-season sunrooms, four-season additions, screen rooms and patio covers for Winnipeg homes. Send your deck or patio measurements and get a room recommendation with an estimated cost before anyone comes out.
A sunroom adds a room without a full addition. Three-season rooms go up on an existing deck or a new concrete pad in a week or two, cost a fraction of a framed addition, and give you April to October outside without the mosquitoes. Four-season rooms are insulated, heated and used every day, which is why they are the most common sunroom built in Winnipeg.
The part that decides whether a sunroom here lasts twenty years is not the glass. It is the base and the roof. Winnipeg sits on heavy clay that heaves with dozens of freeze-thaw cycles every winter, and roofs here carry real snow. A room that was designed for Ontario or the US south cracks at the seams within a few winters. A room built for Winnipeg sits on frost-protected footings or a properly built pad, and its roof is engineered for the snow load the City of Winnipeg requires.
That is why we built Winnipeg Sunrooms around one job: helping Winnipeg homeowners pick the right room for the space and the budget, see real ranges before anyone comes out, and get it built by an installer who has done it through a prairie winter.
We start with measurements, not a sales visit. Send the width and depth of the deck or patio, a photo of the wall the room will attach to, and whether you want three-season or year-round. We come back with the room that fits and an estimated range. If the numbers make sense, the site visit and the written quote come next.
Most Winnipeg sunrooms are installed from May to October, and the best ones are designed and permitted in winter so the crew can start the moment the ground allows.
From the first measurement to the final inspection, we handle the whole room: design, permit, foundation, structure, glass, electrical and finishing.
Aluminum-frame glass rooms on your existing deck or a new pad, used from April to October in Winnipeg.

Learn more →Mosquito-free patios: screen enclosures, solid-roof patio covers and three-wall porches.
Learn more →Layout, roof style, orientation, engineering and the City of Winnipeg or rural municipality permit, handled before the quote.
Learn more →Fogged or cracked panels, failed seals, leaking roofs and screens on existing sunrooms.
Learn more →Sunroom work follows a logical order, and the rooms that leak or fog in year three are the ones that skipped a step. Here's how we approach every Winnipeg home, start to finish.
You send the width and depth of the space, a photo of the attachment wall, and how you want to use the room. We tell you what fits: a screen room, a three-season glass room, or a four-season addition, with an estimated range for each. No visit needed for this step.
We measure the wall, check the deck or pad, the grade, the roofline and where the sun sits in the afternoon. Then you get a written quote with the room, the foundation, the glass package, electrical and the permit.
Drawings, engineering for snow load, and the permit application with the City of Winnipeg or your rural municipality. A four-season room is an addition and always needs a permit; most three-season rooms do too.
Footings or pad, structure, roof, glass, screens, electrical, heating for year-round rooms, trim and cleanup. A three-season room is usually finished in one to two weeks on site; a four-season room in four to eight.
A sunroom company's job is not finished when the last panel goes in. It is finished when the room is warm in January and dry in April. Here is what that commitment looks like.
Send your measurements and get a room recommendation and an estimated range before anyone comes out. We publish our typical ranges on this page.
Frost-protected footings, engineered snow-load roofs, insulated panels and thermal glass. Every room is designed for Winnipeg, not copied from a warmer market.
Foundation, structure, glass, electrical and permit on one quote, so you can compare it line for line with anyone else.
We're focused on Winnipeg and the Capital Region, not a national franchise. We know the permit rules, the lot sizes and the winters here.
Every home is different, and your exact quote depends on size, foundation, glass package, roof style and whether the room is heated. That said, homeowners deserve a straight answer instead of "call for pricing," so here are the typical ranges we see in the Winnipeg area in 2026.
| Service | Typical Range | Notes |
|---|---|---|
| Screen room or solid-roof patio cover on an existing deck | $8,000 – $20,000 | Aluminum frame, screens or open sides, no glass, no heat |
| Three-season glass sunroom, about 12 x 12 ft | $30,000 – $60,000 | Aluminum frame, glass walls, solid or glass roof, on a sound deck or new pad |
| Four-season sunroom, about 12 x 12 ft | $60,000 – $100,000+ | Insulated walls and roof, thermal glass, frost-protected foundation, heating and electrical |
| Larger four-season rooms and custom additions | $100,000 – $150,000+ | Bigger footprints, vaulted roofs, tile floors, full HVAC tie-in |
| Sunroom repair: fogged or cracked glass unit | $400 – $1,500 per unit | Varies by size and glazing type; roof and seal repairs quoted after inspection |
These are typical installed ranges for the Winnipeg area, not a quote. Site conditions (a new pad or footings instead of an existing deck, a tall attachment wall, tight access, electrical runs) move a project within its range. Your exact price is confirmed in writing after a site visit.
We publish these numbers because a sunroom is a real investment and you should be able to budget for it the way you would a kitchen or a garage. Send your measurements and we will tell you which row you are in and what moves the number.
Winnipeg Sunrooms serves Winnipeg and the surrounding Winnipeg Capital Region communities, including Headingley, Oak Bluff, East St. Paul, Niverville, Steinbach, and Selkirk. Each area has its own page below with local details on sunroom installation.
We built dedicated coverage for these communities because the deeper lots and bigger decks outside the Winnipeg city line often make the best sunrooms. Soil, snow and frost across the Capital Region are the same, so homeowners in Headingley or Niverville get the same engineering and the same written-quote process as anyone in Winnipeg proper.
A three-season room is an aluminum-frame glass or screen room with single or double glazing and no heating, 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 people end up using the most.
Typical installed ranges in the Winnipeg area: screen rooms and patio covers $8,000 to $20,000; a three-season glass room around 12 by 12 feet $30,000 to $60,000; a four-season room the same size $60,000 to $100,000 or more. See the full table above.
Often, yes, for a screen room or a three-season room, if the deck is sound and the footings are deep enough. A four-season room needs frost-protected footings or a slab, so it usually gets a new foundation. We check this at the site visit.
A four-season room is an addition and always needs a building permit and engineering. Most three-season rooms do as well, and electrical work needs an electrical permit. We confirm the current rules with the City of Winnipeg or your rural municipality as part of the quote.
Width, depth, a photo of the wall, and three-season or year-round. We reply with the room that fits and an estimated range.
