Pressure washing costs in Kansas City

A Kansas City driveway spends the winter freezing, thawing and wearing salt. NOAA's 1991–2020 normals for Kansas City International count about 107 nights a year at or below freezing, but only about 26 days that stay below freezing all day. So on roughly 81 days a year, a night freeze gives way to an afternoon thaw. The airport also averages a bit over 18 inches of snow a year.

The concrete industry's guide to scaling, CIP 2, explains why that matters for the slab. Concrete that freezes and thaws with moisture or deicing salt on it can flake and peel at the surface, starting as small patches that later merge. For a new driveway, the guide says no calcium or sodium chloride the first year. Use clean sand for traction, and hose off the salt your car drops on the slab when the weather allows. It also says never to use ammonium sulfate or ammonium nitrate as a deicer, since they are chemically aggressive and destroy concrete surfaces.

A spring wash here does two jobs: it lifts the winter's salt film, and it shows you whether the top layer has started to scale. If you see pitted patches or exposed stones, tell your washer before they start. The same guide lists a high-pressure washer as one of the tools for stripping weak, unsound concrete off a slab before a repair, which is the last thing you want on a driveway you only meant to clean.
