A typical residential driveway ranges from $8-$15 per square foot. Q: How long does concrete take to cure? A: Initial set within 24-48 hours, full curing takes about 28 days. Walk on it after 24 hours, drive on it after 7 days. Q: Do you remove old concrete? A: Yes. Full demolition, haul-away, and disposal included in project quotes. Q: Do I need a permit for concrete work? A: Most residential work doesn't require a permit. Retaining walls over 4 feet typically do. Q: Can you pour concrete in the rain or during winter? A: Yes. We work year-round in Seattle. 90% of a concrete project is prep work that can happen in any weather. For the actual pour, we build temporary tent structures to keep rain off the concrete.
