Is 18 feet wide enough for two cars?

It is tight. Two compact cars can fit, but you won't be able to open doors comfortably. For two vehicles we recommend at least 20 feet wide, and 24 feet if you also want storage.

Can I insulate an 18x25 garage?

Yes. Insulation reduces condensation and keeps the space more comfortable, which matters if you plan to work in it.

How tall should the door be?

An 8-foot door suits most cars and SUVs. If you'll store a lifted truck or a boat on a trailer, step up to a 10-foot leg height and a taller door.

One-Car Garage

18x25x9 One-Car Garage

Six extra feet of width turns a single-car garage into a garage and workshop. The 18x25 parks one vehicle comfortably and leaves a full side wall for a workbench, tool chest or freezer, so you're not squeezing past the car every time you need something.

Priced for your address and local wind and snow requirements. Usually by 9am next business day.
