Concrete Sealing

What This Service Involves

Bare concrete in western Washington soaks up rain like a sponge, and that trapped moisture feeds the moss and dark staining you see returning within a season. We first clean and fully dry the slab, then apply a sealer matched to the surface finish so the pores are protected rather than merely coated. A properly sealed driveway sheds water, resists de-icer and oil intrusion, and stays brighter far longer between washes. Because our winters keep concrete damp for months, sealing during a dry stretch is what makes the treatment actually bond.

Benefits

Blocks rain and groundwater from wicking into porous concrete; Slows the return of moss, algae, and dark biological staining; Makes future oil and rust spots far easier to lift; Extends the life of the slab by reducing freeze-thaw surface spalling; Keeps the finish looking freshly cleaned through the wet months

Our Process

1) Deep clean the concrete and remove any existing failing sealer or contaminants; 2) Allow the slab to dry to the moisture level the product requires; 3) Apply the chosen penetrating or film-forming sealer in even coats; 4) Cure and inspect coverage before returning the surface to use

What Affects the Cost

Total square footage of driveway, patio, or walkway being treated; Condition of the concrete and amount of prep or stripping needed; Type of sealer selected, from penetrating silane to acrylic topcoats; Number of coats required for the porosity of the slab; Access, slope, and how much surrounding masking is involved

Best Time of Year

Plan concrete sealing for a warm, rain-free window from late June through September when the slab can fully dry and cure.
