Field note 03

What lifts,and what’s forever.

Every driveway has two kinds of marks on it, and they behave nothing alike. The first kind sits on the concrete: dirt, algae, mildew, tire film, leaf tannins. The second kind lives in it: oil that soaked into the pores years ago, rust that oxidized in place, etching from acid or fertilizer, and the ghost of anything that sat wet on the slab for a season.

Surface marks lift. With the right pre-treatment and an even, section-by-section clean, most driveways come back dramatically — often close to the day they were poured. That’s the honest good news, and it’s most of what we see.

Permanent staining, oxidation, rust pitting and etching are in the material itself, not on top of it. We’ll tell you which is which before we start — not after.

How we tell the difference

At the assessment we test the stain, not guess at it. A surface mark responds to chemistry immediately; an embedded one barely changes. Each stain on your property gets a line in the written report: what it is, what treatment it gets, and how far we expect it to go. Deep-set oil and rust get stain-specific chemistry and lighten substantially — the report says so in exactly those words, so nobody is surprised on either side.

One more honest note: freshly cleaned concrete can reveal marks the grime was hiding — old sealer lines, patch edges, sprinkler shadows. They were always there. The report flags them ahead of time, because a surprise on cleaning day is a failure of the assessment, not the wash.
