These guys are the best. Before you call anyone else, call Rainy Day. They were responsive and at my house quickly with genuine concern. The work was excellent, thorough, and professional. Through the entire process, there was excellent communication and follow-up. This is how a business should be run.

Rainy Day came to my grandmothers house when she had a slab leak in her bathroom. They were extremely helpful and knowledgeable about every step we had to take to get everything fixed. They would always answer promptly with any questions we had and made everything easy on our part. I highly recommend them!!
