Katy splits into two very different cleaning jobs: deed-restriction work in the master-planned communities, and flood residue on properties near the reservoirs. They are not the same problem and they do not respond to the same treatment.

In the master-planned sections — Cinco Ranch, Cross Creek Ranch, Firethorne and the rest — the exterior cleaning conversation is usually about deed restrictions. The association inspects, a letter arrives, and the driveway or the siding needs attention by a date. Straightforward work on relatively new construction.
Closer to the reservoirs it is a different conversation. Properties in and around the Barker and Addicks flood pools carry a history that shows on the exterior: silt lines on brick and fence posts, a grey tidemark on garage walls, mud pressed into the texture of a concrete driveway. That is not algae and it does not respond to the same treatment.
Flood residue is mineral rather than biological. It sits in the pores of the surface instead of growing on top of it, which changes the approach in two ways.
If your property took water, say so when you call. It changes the quote, and a crew that has done post-flood work will ask about it before you mention it.
Katy is still building, and a house in its first year often carries things a five-year-old house does not: mortar splash on brick, paint overspray, adhesive marks on concrete, a driveway stained by whatever was parked on it during the build. These are builder's mess rather than weathering, and several respond to specific treatments rather than a general wash. Point them out rather than assuming they will lift.
The deadline mechanics are the same across the Houston master-planned communities, and they are covered in full on the Cypress page. The short version for Katy: read the date rather than the tone, and tell the association the work is booked.
