A cleaner patio you’ll actually want to use.

Getting Rid of Algae and Mildew on Houston Concrete

Houston’s heat, humidity, and frequent rain create ideal conditions for algae and mildew. If your concrete patio is turning green, dark, or slick,
the right cleaning method can restore the look and help slow down regrowth.

Common Houston patio problems

Green algae in shade and low spots
Black mildew speckling
Slippery film after rain
Oil and grease stains near grills
Rust stains from furniture and planters

What a proper clean solves

Removes organic growth and discoloration

Reduces how quickly stains return

Why Concrete Patios Get Dirty Faster in Houston

Concrete is porous, so it absorbs moisture and holds onto grime. In Houston, that moisture can linger for days, especially under trees, near fences,
and in spots where drainage is poor. The result is recurring algae and mildew that can make concrete look permanently stained.

High humidity feeds algae and mildew growth
Frequent rain keeps patios wet longer
Shade prevents surfaces from drying quickly
Puddling and sprinkler overspray accelerate staining

Best Way to Clean a Concrete Patio in Houston

In many Houston backyards, a rinse alone won’t cut it because organic growth bonds to the surface and sits inside the pores. The most effective approach
usually combines pre-treatment, proper dwell time, and a controlled rinse to avoid striping or etching.

Pressure Washing

Great for heavy dirt and grime
Works best with a cleaner pre-treatment
Too much pressure can damage older concrete

Soft Washing

Low pressure, cleaner-driven results
Often better for algae and mildew
Typically safer on worn or aging slabs

Many Houston patios do best with a hybrid process: treat the growth first, then rinse thoroughly to lift embedded grime and reduce residue that can
attract new staining.

Concrete Patio Cleaning Cost in Houston, TX

Pricing depends on patio size, stain severity, accessibility, and local rates. In Houston, patios with heavy algae or mildew often require stronger
pre-treatment and a more thorough rinse cycle to slow down regrowth.

Houston Concrete Patio Cleaning FAQs

How often should I clean my concrete patio in Houston?

Most homeowners do well with a deep clean once or twice per year. If your patio stays shaded, holds water, or turns slick after rain,
you may need cleaning more often to control algae and mildew.

Why does algae and mildew keep coming back so fast?

Regrowth is usually caused by moisture that doesn’t dry out, shade, and runoff. Improving drainage, redirecting sprinklers,
and reducing puddling helps your patio stay cleaner longer after a deep clean.

Is pressure washing safe for Houston patios?

Yes, when done correctly. The key is the right tip, consistent distance, and avoiding excessive pressure on older or already-worn concrete.
For organic staining, a cleaner-first approach (soft washing) is often safer and more effective.
