Walter Stewart Asphalt Sealcoating
Walter Stewart Asphalt Sealcoating is a family business that seals and repairs existing asphalt driveways around the Denver metro, and its site also mentions commercial parking lots. Its site and reviews describe sealcoating and crack filling, with cracks filled with hot rubber and a coating applied over them, and no new paving. It is a service-area business, with hours from 7 AM to 7 PM, Monday to Saturday.
What people praise
- Cracks filled with hot rubber and coated for durability, said a customer who re-seals a 180-foot driveway every three years
- Clean edges along concrete and rock walls, with no overspray
- Repeat customers who come back for another seal coat
- Honest, upfront and thorough work, according to several reviewers
- Spotless equipment and a family crew
Worth knowing
- Its site and reviews describe sealing and repair but no new paving, so ask before hiring it for a driveway that needs replacing
Our take: A perfect 5.0 from more than 70 reviews, for sealcoating a driveway that is still in decent shape. When the surface needs to be repaved, ask about that work first or call a paving contractor.
