How it works
How do you choose a concrete sealing company in St. Louis?
Hire a sealer who applies penetrating silane/siloxane sealers (not topical acrylic), seals between May-June or September-October when air temps hold 50-90 degrees, inspects drainage and caulked joints first, and backs sealing timing around your driveway's age and winter schedule.
