Replacing the door to your home can be a messy process so it is good to apply some forethought and tidy up a little before you begin. Not only will this improve the process but it will ensure that any operations do not damage the surrounding area. Begin by clearing out any furniture, wall hangings and other items from the front of the home. If you will be installing doors in the interior of the home, make sure that the path from the exterior to the door in question is properly cleaned and cleared. You will also need to clean and clear the area around where the employees will be working.
