Exterior Cleaning
Katy, TX.
Full exterior package: house, driveway, walkways, and gutters. Serving Cinco Ranch, Cross Creek Ranch, Firethorne, and all of Katy.
Why Katy homes choose PrimeStar for exterior cleaning.
Katy homes built during the 2000s and 2010s along the Grand Parkway and I-10 West corridor use a mix of brick, Hardy board siding, and stucco that each require different cleaning approaches. Hardy board develops green mildew streaks within 12–18 months in full Gulf Coast humidity without annual treatment. Brick in newer Katy subdivisions accumulates white efflorescence from mortar joints plus organic green film on the lower courses near lawn sprinkler spray zones.
We clean all exterior surfaces using a low-pressure soft wash process — no high-pressure blast that can force water behind siding, lift caulk, or etch stucco. Biodegradable detergent is applied, allowed to dwell, then rinsed from the top down. Gutters and downspouts are cleaned of black streaking (oxidation from inside the gutter) using a non-abrasive exterior cleaner.
We dispatch via I-10 West / Grand Parkway — most Katy neighborhoods are within 25 minutes. Frequently combined with roof soft wash or driveway cleaning in the same appointment — ask about bundle pricing. Free 24-hour written quote.
