Riverock Surfacing Company was contracted to repair fiberglass in a pool and reseal our riverock deck that was installed by RSC 18 years ago. 15k latter the pool has 10 times the cracks and the deck is stained in over 15 locations. Tom the owner states this will be resolved and dose not return calls now. They changed payment terms in the middle of the contract. I am sorry to say I could not recommend them.
