Many of the services we provide must be done professionally to prevent damage to your structure. If you do not have the proper knowledge of pressure washing, you could end up breaking, damaging, or cracking the structure you are cleaning. Unfortunately, this happens frequently when people try and DIY a job themselves. We recommend always consulting a professional. Wood, older brick, roofing shingles, and other softer substances can be destroyed or damaged if an incorrect pressure washing method is used.
