Why a Michigan driveway needs sealing on a schedule
Most Sterling Heights driveways were never sealed, which is the single biggest reason driveways from the 1970s and 1980s show surface spalling and pitting today. Sealing a driveway is the cheapest, simplest, and highest return maintenance step in the entire life of the slab. A 2 to 3 year reseal cycle keeps water from soaking into the slab, keeps road salt from chemically attacking the surface, and keeps the freeze and thaw cycle from blowing the top layer of concrete off. The slab itself lasts decades longer when the surface is sealed and the chemistry is kept off it.
A proper driveway sealing job runs in three steps over a single working day. First, the slab gets pressure washed to remove loose dirt, deicer residue, oil drips, and any old failing sealer. The slab needs to dry fully (typically 24 to 48 hours depending on weather) before the new sealer goes on. Second, the sealer gets applied in a roller pass, with care taken to avoid puddling at the low spots and to keep the coat consistent. Third, a second coat goes on once the first has set up, usually a few hours later the same day. The two coats together give the penetrating siloxane time to wick into the surface pores and form a hydrophobic barrier that water beads off instead of soaks into.
- Penetrating siloxane sealer wicks into the slab, not a film on the surface that peels.
- Hydrophobic barrier rejects water and road salt without sealing in moisture from below.
- Same day install on most residential driveways with no closure beyond a few hours.
- Reapplied every 2 to 3 years for ongoing protection, much cheaper than replacement.
- Visible wet look sheen after cure is a side effect, not the goal.
Sealing is the cheapest service on this site. It prevents the most expensive ones (repair, resurfacing, replacement) from being needed in the first place. Most Sterling Heights driveways with surface spalling, pitting, or scaling damage today were not sealed on a 2 to 3 year cycle. The contractor doing the sealing will note any cracks or joint openings that need attention before the sealer goes on. Sealer over an open crack just traps water inside the slab. That accelerates the damage rather than preventing it.
If a Sterling Heights driveway has never been sealed or has not been resealed in 3 or more years, the form or the phone above books a free walk through to assess the slab and quote the sealing job. Most residential driveways are a same day job with no driveway closure beyond a few hours.
