Winnipeg, MB & the Capital Region
Three-season sunroom installation in Winnipeg, MB. Aluminum-frame glass rooms on your deck or a new pad, with estimated costs before a site visit.
A three-season sunroom is an engineered aluminum frame with glass walls, usually sliding windows with screens, and either a solid insulated roof or a glass roof. It is not heated and not insulated to house standards, so it is a spring, summer and fall room. On a sunny March day it is warm; in January it is a storage room. Most are built on an existing deck or a new concrete pad.
Three-season rooms suit Winnipeg homeowners who want the deck without the mosquitoes and the rain, and who do not need the space in winter. Common sizes are 10 by 12 to 14 by 20 feet. The room needs a straight attachment wall, a deck or pad that is level and sound, and a roofline that lets the sunroom roof tuck under or flash against the house.
Single-glazed vinyl windows keep the price down; double-glazed glass with screens is the usual Winnipeg choice because the shoulder seasons are long. Solid roofs with insulated panels keep the room cooler in July than glass roofs and carry snow better. Options include ceiling fans, LED lighting, a door to the yard, and a tile or composite floor over the deck.
We quote only after measuring the wall and checking the deck or pad, we specify the snow-load rating of the roof in writing, and the structure and installation are warranty-backed. If the existing deck will not carry the room, we say so and quote the pad.
