Castles Home Service restores, cleans, and maintains all types of natural stone surfaces for residential and commercial clients in Monterey, Santa Cruz, Santa Clara, San Mateo, San Francisco, and Alameda Counties. In addition to working on everything from countertops and floors to interior and exterior vanities, the family-owned and operated company has the in-house capabilities to clean and seal stone, tile, and grout in high-traffic areas like kitchens and bathrooms.

Owner Brian Franta says Castles Home Service’s customer-oriented approach to the stone restoration process has been vital to its success. “Our favorite part of the job is solving our clients’ problems and seeing their faces when we show them the results of our work. We’re often able to make a dramatic difference in what they considered to be a lost cause, which is always rewarding.”

Castles Home Service educates its customers about their stone surfaces so they know how to avoid expensive issues like etching in the future. “A lot of homeowners don’t know the best ways to care for their surfaces, so we walk them through maintenance procedures that help them get the most value from their purchases,” says Mr. Franta. “Our treatments are designed to protect surfaces for many years.”
