Pro Seal helps to restore the beauty of your hardscapes. As a premier Northern NJ power washing and sealing company, we preserve the value of your concrete, pavers, natural stone, tile roofing and more. Our high-end systems for power washing and sealing help to prevent mold and mildew growth for five-plus years. Weather, vehicle and pedestrian traffic, and sunlight can cause your stone to deteriorate over time. Our proven power washing and sealing options prevent the penetration of water, resulting in greater strength and durability, enhanced natural colors and reduced mold and mildew - all of which leads to the need for less frequent power washing, decreased maintenance costs and increased curb appeal.
