Arch City Sealcoating

Arch City Sealcoating focuses on repairing and preserving asphalt for property owners in St. Louis, Missouri, and the surrounding area. The business is family run and locally owned, states that its team is licensed and insured, and is available seven days a week for estimates, which are free.

Sealcoating is the company's namesake service. It uses commercial-grade sealants to protect driveways and parking lots from UV exposure, heat, water, salt and chemicals, and to restore an even black finish that gives fresh striping strong contrast. Before sealing, the crew evaluates the pavement and advises whether cracks, potholes or weak spots should be handled first. The company suggests resealing every two to five years, depending on traffic and weather.

Cracks are treated in two ways. Narrower cracks are sealed with hot- or cold-applied material, while large or widespread cracking is filled with asphalt and then sealed. Potholes are repaired by cutting out the damaged section, rebuilding the subgrade and placing new asphalt, using either hot or cold mix. For lots with widespread pitting, cracking and minor potholes, the company recommends repairing those areas and the subgrade beneath them and then placing an asphalt overlay, provided the pavement has no structural problems.

Pavement marking services include line striping, ADA-compliant accessible parking layouts, and custom markings and signage. For homeowners, the company installs new driveways and widens, extends, patches, resurfaces or replaces existing ones, and it resurfaces roads and parking lots as well.

Every customer is enrolled in a complimentary annual inspection program. Each year the company checks driveways, parking lots and walks for edge erosion, pitting and cracking, reviews the condition of the seal coat and markings, and sends a cost estimate when repairs or restriping are needed. Its work is guaranteed for both materials and workmanship.
