For a detached garage addition, how long does it take to build?

Briefly, depending on the specific garage, it can take anywhere from a couple of weeks to a couple of months. Why?

First of all, will the new garage have a standard floorplan or a custom design? When building any garage that is truly a custom design, the first stage is the completion of the custom design (the blueprint). Further, it is always important to consider the specifics of the soil and terrain to make sure that the design is a good match for the actual property and ground.

Once the design is ready and the permits are issued (plus the financing has been secured), then one of the next big factors that can influence the how long the actual construction takes is... the weather. If there are no delays from severe weather, then the construction of the garage addition can at least begin to be built in as little as a week (if there are absolutely no delays relating to all of the initial "paperwork"). So, completion time for custom garage construction can range from over two months (for large custom garage additions) down to a few weeks for a small free-standing garage of a common design.

What are the stages in the process of building a custom detached garage?

Before the actual construction stages, there are the pre-construction stages, including the survey of the property, the architectural drafting of the blueprint, the obtaining of building permits, and the financing of the construction. In some cases, people will have completed all of those steps before contacting the building contractor. However, our garage builders can also help you to complete all of these steps of planning and preparation.

Next comes the actual construction of the free-standing detached garage. Typically, that involves preparing the ground (leveling the dirt) to be ready for pouring the concrete foundation. Then, the crew will set up the boards that will form the wet concrete as it dries (plus place the grid of steel for reinforcement). Once the slab is ready for framing, then the frame can be built. Roof trusses can eventually be attached and then the roof decking, exterior roof, and interior walls can be finished (including insulation). Besides later steps like the siding and painting, one of the last steps is typically the installation of the garage door and the opener.

How much will it cost for the garage builders to construct a free-standing garage addition?

Naturally, the cost of custom construction jobs will not be easy to estimate until after the main details of the desired garage are clear to the estimator. With any big job, there will be a few variables that will allow people to keep the initial costs low (like the angle and materials of the roof). When you contact a garage construction supervisor through this site, it is best to let us know your top priorities, such as "curb appeal," keeping the budget modest, urgency of fast completion, or something else.
