"Protect your investment" Throughout my years of being in this business I have seen nice homes, cars, RV's and boats. What really get's me about this issue is that those owners really don't care about protecting them from the elements. I can tell you that the more attention you pay to your investments the more you will get in return when you decide to sell them. If you are a vehicle owner you need to have your vehicle waxed and sealed every six months.
Once before Winter and once before Summer. If you own a home or property you should get the exterior Pressure Washed and have Algae, Mold or Mildew removed as it grows. The longer you let it grow the worse it will stain your property. Those three funguses can cause health issues to the occupants of those properties.
