Exterior Mold & Mildew Removal for Concrete in New Mexico

Pressure wash with a surface cleaner for concrete. Killing and removing mold, mildew and algae from siding, decks, walkways and fences, with treatment that slows regrowth. Typical cost $250-$700.

Grime, mildew and stains build up a little at a time until one day the outside of your property looks years older. Exterior Mold & Mildew Removal for Concrete in New Mexico brings it back, usually in a single visit. With concrete, the right approach is pressure wash with a surface cleaner.

Method and pressure

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.

Serving New Mexico and nearby towns

In New Mexico, siding and stucco get dull from dust and spotted from sprinkler overspray more than from mildew. Hard-water spots need a different treatment than dirt, so we identify the stain before choosing the cleaner.

Much of New Mexico 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 New Mexico 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.

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.
