Mold and mildew can damage exterior structures of a home such as the sidings, decks, balconies and patios. Wooden materials might get significantly damaged if such microorganisms are allowed to grow rampantly. Homeowners can take several steps to eliminate and prevent unsightly mold and mildew. Professional power washing services provide effective solutions for thoroughly cleaning exterior surfaces. High-pressure water can penetrate deep into any cracks and openings in different materials such as plastic, wood, metal, and other natural or synthetic textures. Mold and mildew thrive in hard-to-reach areas that are moist and have poor air circulation. Before a power wash, exterior surfaces are treated with soap that penetrates deep into different types of materials. The soaking application is designed to loosen up any dirt, grime and microorganisms that might be physically bonded to surfaces. A burst of high-pressure water then effectively sweeps away all of the debris. After a power wash, a sealant should be applied to provide long-lasting protection. Wooden decks and patios can be covered with several layers of thin coatings that prevent mold and mildew from forming. Additionally, most sealants provide protection against UV rays that could gradually cause wood to fade away in texture. Termite control is also an element of wooden sealants that are designed to last for several seasons. Wooden decks and patios that are infested with bacteria can be treated with a powerful chemical shock that includes chlorine as the main ingredient. After all of the bacteria is effectively killed, special polymers can be applied all over a deck or patio for protection. Deck cleaning and staining solutions can save homeowners thousands of dollars in future remodeling and repair costs. Homeowners should realize that sidewalks, driveways and steps could also be infested with microorganisms. It's important to power wash concrete and stone surfaces on a seasonal basis. Power washing also removes any debris that might be stuck in porous openings of driveways and sidewalks. During the wintertime, such small cracks might enlarge due to freezing temperatures and the accumulation of ice. Sealants should be applied to prevent such problems that might eventually require an entire resurfacing procedure. Tiles around the perimeter of a swimming pool are especially susceptible to algae growth. A distinct green or yellow layer might quickly develop around the edges of a pool's basin. Chemical algaecides can be used to clean infested tiles.
