House washing and pressure washing inColleyville

Start with the shaded wall, because it is what people actually call about. A north elevation under an oak in Woodbriar or Creekside grows a green-black mildew film that no amount of pressure removes, because pressure only takes the top off and leaves the root structure in the brick pores. It has to be treated with chemistry and dwelled. Cleaned properly it stays clean for a full cycle; blasted, it is back before the next season — and you have opened the mortar joints for nothing.

The canopy sheds tannin-heavy leaf litter and pollen year-round. That debris breaks down, washes over the drip edge, and bonds to the gutter face as tiger striping — which is why Colleyville has more brightening work per house than anywhere else on our list. Bonded oxidation does not come off with house wash solution, so it is a separate process and a separate line on the quote.

Third is the ground. Long broom-finish driveways under a dense canopy stay damp, and damp concrete in shade grows the same organics the walls do. The green cast on a Montclair Estates driveway is almost never dirt — it is growth, and it comes off with a surface cleaner and the right pre-treatment rather than more pressure.

Trimming limbs back off the house is the highest-return thing a Colleyville homeowner can do, and we will tell you that even though it means we see you less often.
