Calgary Detached Garages

Demolition

Demolition of existing garage includes the removal and disposal of existing materials, including concrete pad, fencing, wall and roof structure removal, electrical and gas lines removal and capping. The standard price to remove existing detached garage is tarting at $17.5/per sq.ft., some factors can affect the overall cost. Where hazardous materials such as asbestos are present, their removal must be carried out safely by qualified specialists in accordance with applicable regulations. The extent of demolition required will depend on the existing site conditions and the materials encountered during the work.

‍Difficult Access

Tight lots, narrow driveways, restricted construction access or limited space for equipment and material deliveries can make a project more difficult and increase labour and equipment costs . Occasionally, additional concrete aggregate delivery costs may apply when delivery truck access to the site is limited or unavailable.

‍Soil and Site Conditions

Poor soil conditions, drainage issues, slopes, or other site conditions may require additional excavation, grading, site preparation, or foundation work. If a retaining wall is required, additional permits, development approvals, and structural drawings may be necessary, resulting in additional costs.

Concrete Requirements

The concrete work for the detached garage foundation will vary depending on the garage design, site conditions, and overall size. Additional excavation, thicker slabs, extra reinforcement, engineered foundations, or other structural requirements may increase the project cost. Garages with slabs exceeding 55 m² (592 sq. ft.) require an engineered foundation design, which will add costs for structural drawings, engineering, as well as additional labour and materials required to construct the foundation pad.

Garage Doors Extras

The cost of the garage door will depend on its size, style, material, insulation level, and operating system. Upgrades such as windows, decorative finishes, painting, higher insulation ratings, or automatic openers are available through our company. Varies door sizes are available in case tall or wide vehicles are being parked in future garage. Let us know your plans and we will provide the price based on your needs.

Insulation

If you want a garage that stays more comfortable during Calgary’s cold winters, insulation and a poly vapour barrier can be added to the garage wall cavity. The overall cost will depend on the size of the garage, wall thickness, and the level of insulation required. Additional insulation in the ceiling or garage door can also be considered for improved energy efficiency and comfort.

Drywall

A basic unfinished garage and a fully finished, drywalled space are two very different projects. If you're looking for a clean, complete finish, we highly recommend completing the drywall and painting during the initial garage construction. This helps avoid the hassle of moving and protecting your belongings later when finishing the garage.

Heating

Keep your garage comfortable and functional year-round with professional garage heater installation. We can help with heater selection, installation, venting, and required connections to ensure your space is heated safely and efficiently. Our current price for garage gas heater pckage is $6,600, which includes heater and undergroung line installation and trenching, permitting and dedicated electrical services.

Upgraded Siding

Premium siding profiles, colours, and materials are great options to give your detached garage an upgraded look. Darker colours and wood-grain finishes typically cost more from the supplier, so this should be considered when matching the garage to a home with darker siding. James Hardie siding can be selected for its authentic appearance, durability, and added protection to the garage against Calgary’s harsh weather conditions, including hail.

Electrical

Electrical requirements can vary significantly depending on how you plan to use your garage. Additional outlets, lighting, circuits, EV charging, and workshop equipment can add functionality to your custom garage. At Corsac Construction, all of our detached garage packages include a 40-amp electrical service and dedicated garage panel, compared to the 15-amp service commonly offered as a standard by other builders. A 40-amp service provides a solid base for EV charging. However, if you plan to use high-powered tools or workshop equipment, we highly recommend upgrading to a 60-amp service and subpanel.

Windows

Our standard package included 30"x36" picture frame window. We offer various window sizes and functionality. Consider other options as stock windows are available in a variety of styles and sizes. If you’re looking for a custom window colour or size, let us know, and we’d be happy to look into the available options for you.

Architectural and Engineering Requirements

More complex custom garage designs, unusual lot conditions, structural requirements or permit requirements typically involve architectural or engineer services. We can provide a consultation on what is required for a successful permit application and fast approval.

Retaining Walls

If you are building a detached garage but your property has a significant slope or grade change, retaining walls may be required. In Alberta, retaining walls over 1.2 m (4 ft.) require engineering and permitting. The cost of the retaining wall varies depending on the height, length, permitting and structural requiredments.
