How to Clean the Exterior of Your Garage

If it’s not been all that long since your new garage was built, then now might be the perfect time to clean the exterior. After a few years, the brickwork can start to appear darker than it was originally and the windows can gather dirt, taking away the gleam that was once present. In this case, you may wish to give the garage a clean and restore it back to its original condition.

Cleaning the whole exterior could take as long as four hours, depending on how thorough you are looking to be. Therefore, make sure you have enough time dedicated to carry out the task in one go, maybe doing so on the weekend when you have more spare time. Here’s a look at how you can clean your garage, without causing any damage to its features and structure.

    Use a jet wash machine to clean the walls of the garage. This will get rid of the build-up of dirt and make the brickwork look fresher. However, don’t use the jet wash machine on the garage door or the windows as this may cause damage to these more fragile surfaces. Remember that these machines can be extremely powerful, so you might take some of the cement away when cleaning the brickwork.

    Once the walls have been treated, use a cloth and a bucket of warm soapy water to clean the windows. Make sure you tackle the built up of dirt in the corners and along the window fixings too, so that the both the windows and the surroundings look clean.

    Clean the garage door in the same way by using a clean cloth and a bucket of warm water. Again, you don’t want to use the pressurised jet wash on this part of the structure as it may cause paintwork to peel away, or leave small dents on the surface.

    If you’ve worked your way around the walls of the building, the last area you will need to address is the roof. This is where moss, twigs and leaves can gather, so you may need to use a ladder to get on to the roof and sweep away any debris. Make sure you have assistance during this stage and take care as you obviously won’t want to fall off the roof.

    After completing these stages, make your way around the garage and see if all areas have been treated. If you notice any sections that you have missed then simply clean them and then stand back and admire your newly cleaned garage.


  • Be careful when using the jet wash machinery on the garage walls and don’t use it for the main doors and windows.
  • Always have assistance when going on to the roof.
