1. Full septic system replacement

Larry Fockler Construction did a great job for us replacing our septic tank and bed. We had a saturated bed due to tree root infestation, an old tank, and a challenging property to access. They provided us with a detailed design for the new system, helped us get the permit through the Town of Richmond Hill and easily passed the inspections. Their estimate was reasonable, and at the end they came in right on budget and on schedule. Great customer service as well. We would be happy to recommend them, email cathyjhunter@hotmail.com.
