We are very satisfied with National Sealing Company! We finally have peace of mind knowing our pool area is safe. We did the an anti slip application and it turned out great. Don’t make the mistake of going through any other company. We paid another company to seal our patio and do an anti slip coating and it was a nightmare, making our deck more slippery than it was before. This company does quality work and specializes in anti slip applications. Our applicator Mark was great. I spoke with Kenny initially and he coordinated the appointment and educated me about their product. I can’t thank you enough!!! ????
