Looking for exterior mold & mildew removal for concrete in Conroe, TX? We look at the surface first, choose the right method and pressure for it, and give you a price before any work starts. With concrete, the right approach is pressure wash with a surface cleaner.

How we clean it

Pressure wash with a surface cleanerCleaning method
Usually 2,500-3,500 PSI with a rotary surface cleaner for even resultsPressure

Cleaning solution: A degreaser for oil spots and a pre-treatment for organic growth; post-treatment slows regrowth.

Caring for concrete

Plain broom-finish concrete is the surface pressure washing is made for. A rotary surface cleaner gives an even finish without the stripes a wand leaves, and hot water helps with grease and oil.

Avoid: Holding a narrow tip close to the surface, which etches lines into the cream layer of the concrete.

How often: Every year, or every 6 months in shaded, damp spots.

Local exterior mold & mildew removal for concrete for Conroe, TX

Mildew and algae are the main reason Texas homeowners wash their siding. Shaded walls can turn green within months, and pressure alone doesn't kill the growth, so we use a soft wash solution that does.

Parts of Texas are exposed to hurricanes and tropical storms. After a storm, washing removes mud, debris and salt spray from siding, screens and walkways. Check for damage first: loose siding, broken screens and roof damage need repair before anyone washes them.

Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.

Much of Texas has hard water. Sprinklers and misters leave white mineral spots on walls, windows, fences and pool tile, and those spots need a mineral-safe cleaner, not more pressure.

Some cities in Texas limit outdoor water use, including washing hard surfaces with a hose, especially during drought declarations. Pressure washers use far less water than an open garden hose, but rules vary, so it's worth checking your city's current restrictions. Wash water should also be kept out of storm drains.

Do you use high pressure for exterior mold & mildew removal for concrete?

For concrete: usually 2,500-3,500 PSI with a rotary surface cleaner for even results. What we avoid: holding a narrow tip close to the surface, which etches lines into the cream layer of the concrete. We keep the pressure even and controlled, with the right tools for the surface.

Is exterior mold & mildew removal for concrete safe for my plants and pets?

We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.

How often should I schedule exterior mold & mildew removal for concrete?

Every year, or every 6 months in shaded, damp spots. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.

What if it rains on the day?

Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
