A detached garage is a full construction project, not a weekend add-on. It starts with a permit application to the City of Mississauga, then a footing and foundation pour, framing, roofing, siding to match (or intentionally contrast) the house, an overhead door, and usually electrical for lighting and outlets. Depending on the lot, a builder may also need to deal with setback rules, tree protection, drainage away from the neighbor's property, and grading. Some homeowners add a workshop layout, a loft for storage, or rough-in for future heating.
We're tracking 25 businesses in this category around Mississauga, ranging from small crews who specialize in garages and additions to larger general contractors who take on garages as one part of a bigger portfolio. That range matters because a garage builder should be comfortable pulling permits, coordinating an engineer's stamp when required, and standing behind the concrete work, which is where most long-term problems (cracking, heaving, poor drainage) actually start.
Our ranking weighs permit and code experience, quality and consistency of past builds, communication during the project, and how disputes or delays get handled. The full breakdown of how we score is on our methodology page. See the current results on the ranked list of detached garage builders in Mississauga.
