From initial site assessment through final finishing, find the right professional for every aspect of your garage project:
Detached Garage Construction
Complete new-build detached garages from single-car (12x24 feet) to oversized multi-bay structures (30x40+ feet). Includes site preparation, foundation engineering to meet NB frost depth requirements, wood or steel framing, roof trusses rated for regional snow loads, siding to match or complement your home, and overhead door installation. Detached garages offer maximum flexibility in size and placement and are ideal for workshop, storage, or hobby use where separation from the house is preferred.
Expect $25,000-$75,000+ depending on size, finishes, and whether the space includes heating, insulation, or plumbing.
Attached Garage Addition
Garage additions that integrate with your existing home's foundation, roofline, and exterior finishes. Requires careful structural engineering to tie new foundation walls to existing footings, match roof pitch and drainage, and install proper fire separation between garage and living space as required by the NB Building Code -- including 5/8-inch Type X drywall on the garage side and a self-closing, fire-rated door. Particularly popular in established NB neighbourhoods where lot sizes limit detached garage options.
Costs $35,000-$90,000 depending on size, integration complexity, and whether the addition includes a bonus room above.
Garage Conversion & Renovation
Transform an existing garage into functional living space -- home office, in-law suite, family room, rental unit, or workshop upgrade. Conversions involve framing and insulating exterior walls to R-24 residential standards, upgrading the concrete floor with insulation and finished flooring, installing egress windows for bedrooms, adding HVAC for year-round comfort, and ensuring the space meets NB Building Code requirements for habitable rooms including ceiling height, ventilation, and electrical.
Costs $20,000-$60,000 depending on the scope of conversion and level of finishing.
Garage Door Installation
Supply and installation of sectional overhead doors, carriage-style doors, and commercial roll-up doors in standard and custom sizes. Includes proper header framing, weatherstripping for NB's freeze-thaw cycles, insulated door panels (R-6 to R-18) for heated garages, spring systems rated for 10,000+ cycles, and smart opener installation with battery backup for power outages common during NB ice storms. Door selection must account for wind load ratings appropriate for your location -- coastal communities face higher exposure requirements.
Costs $1,200-$5,000 per door including installation, with insulated steel doors in the $2,000-$3,500 range for most NB homes.
Garage Insulation & Climate Control
Insulation upgrades for garage walls (R-20 to R-24), ceilings (R-40 to R-60 if living space above), and doors to create a year-round usable space. Includes vapour barrier installation, air sealing around door frames and penetrations, and climate control options ranging from electric baseboard heaters to mini-split heat pumps. Proper insulation is essential for any NB garage used as a workshop, home gym, or storage for temperature-sensitive items, and is required by code for attached garages sharing a wall with heated living space.
Costs $3,000-$15,000 depending on garage size, insulation type, and heating system selection.
Garage Foundation & Slab
Foundation engineering and construction including concrete slab-on-grade with thickened edges, frost wall foundations extending below the frost line, and full basement-style foundations for garages with planned living space above. NB's frost depth requirements (1.2 metres in southern regions, 1.5 metres in northern NB) make foundation work the most critical phase of any garage build. Includes excavation, forming, concrete pouring, waterproofing for below-grade walls, and drainage systems for sites with high water tables.
Costs $4,000-$18,000 depending on foundation type, garage size, and site conditions.
Garage Electrical & Lighting
Complete electrical systems for new and existing garages including dedicated sub-panel installation (100-200 amp), interior and exterior LED lighting, GFCI-protected outlets for power tools and vehicle charging, 240V circuits for welders, compressors, and EV chargers, and heated garage floor circuits. All garage electrical work in NB must be performed by a licensed electrician and inspected by the NB Department of Public Safety's Electrical Inspection branch. Proper electrical planning at the design stage prevents costly retrofits later.
Costs $2,000-$8,000 depending on service size, number of circuits, and specialty requirements like EV charging.
