Power Washing

Before you think about repainting the entire exterior of your house, first do a thorough cleaning by power washing it. Make sure you invest in a good cleaner that is specifically made for siding. You can purchase at any of the big box stores or any hardware store. Don't cut corners by just hitting the siding with high pressure water - it won't come completely clean.

Once your cleaning is completed, then analyze and see what needs to be done. You may find the entire house needs repainting, but you may also find you only need to do minor repairs and painting.
