What are the pros and cons of a stick-built vs prefab garage in New Brunswick?

A stick-built garage offers maximum customization and typically better long-term durability in NB's climate, while a prefab (pre-engineered or kit) garage offers faster construction and potentially lower upfront cost for simple designs. Both approaches are common across New Brunswick, and the right choice depends on your budget, timeline, site conditions, and how you plan to use the garage.

Stick-built garages are constructed on-site from the ground up — foundation, framing, roofing, siding, and finishing are all done by your contractor on your property. The major advantages are complete design flexibility (any size, shape, roof pitch, door placement, or feature you want), the ability to match your home's architecture exactly, and superior structural performance when built by an experienced NB contractor who understands local snow loads of 2.4 to 4.8 kPa, frost depth of 4 to 5 feet, and Maritime wind conditions. A stick-built two-car garage (24x24) in NB typically costs $40,000-$70,000 including foundation, and the build takes 3-6 weeks depending on weather and complexity. The main drawbacks are higher labour costs, longer construction timelines, and greater dependence on your contractor's skill and reliability.

Prefab or kit garages arrive as pre-cut, pre-engineered packages that are assembled on a prepared foundation. These range from basic panelized wall and truss kits (you provide the foundation, siding, roofing, and labour) to fully pre-engineered steel building packages. A prefab wood-frame kit for a 24x24 garage runs $12,000-$25,000 for the kit alone — but you still need to add foundation costs ($8,000-$15,000), assembly labour ($5,000-$12,000), siding, roofing, electrical, and finishing, which can bring total costs to $35,000-$60,000. The advantages are faster assembly (walls and roof can go up in 2-3 days versus 2-3 weeks for stick-built), consistent quality of pre-cut components, and simpler project management.

NB Climate Considerations

The critical question for any garage in New Brunswick is whether the structure can handle the province's heavy snow loads, deep frost, high winds, and Maritime moisture. Stick-built garages designed by a local contractor are inherently tailored to NB conditions — the truss engineering, foundation depth, and fastening schedule all reflect local building code requirements. Prefab kits, on the other hand, are often designed for national or North American markets and may not meet NB's specific snow load requirements without upgrades. Before purchasing any prefab kit, verify that the truss engineering is rated for your specific NB location's ground snow load — a kit designed for southern Ontario's 1.5 kPa snow load will fail under Bathurst's 4.0+ kPa loads.

Foundation requirements are identical regardless of which approach you choose. Every garage in NB needs a foundation that extends below the 4 to 5 foot frost line — no prefab kit eliminates this requirement. Some prefab sellers advertise "no foundation needed" for floating slab designs, but these are not appropriate for NB's frost depth and will heave within the first winter.

Prefab steel building garages (Quonset-style or rigid-frame) are a third option worth considering. These are discussed in a separate article, but briefly — they offer excellent snow-shedding, long lifespans, and lower maintenance, though they can be more difficult to insulate and finish for workshop or heated use.

Practical advice: If you want a garage that matches your home, includes features like a bonus room, workshop wiring, or heated space, and will last 50+ years in NB's demanding climate, a stick-built garage from an experienced local contractor is the better investment. If you need a simple, unheated detached garage for vehicle storage and have a tight budget, a prefab kit assembled on a proper NB-spec foundation can save 10-20% on overall cost. Either way, the foundation and electrical work must be done by licensed professionals — these are not areas where shortcuts are safe or legal in New Brunswick.
