If the surface is still sound, yes, and it's the cheapest protection it will ever get. Old concrete that's already spalling badly or heaving is past what a sealer can do, and Todd will tell you honestly which side of that line yours is on.
What does resealing cost?
It depends on square footage and surface condition, so the honest answer is a written estimate, not a guess. The estimate is free, Todd writes it himself, and sealing runs a small fraction of what replacing concrete costs.
Will sealing change how my concrete looks?
On flat concrete, no. The penetrating sealer soaks in with no film, no gloss, and no change in traction. On stamped concrete, yes, in the direction you want: the color and depth come back.
When can concrete be sealed in Englewood?
Late spring through early fall is our busy season, while surfaces are dry and temperatures hold. Fall timing pays off fastest, because the concrete goes into freeze-thaw season protected.
