A 2026 customer said Ratta arrived on time every time over six years and was careful not to damage the landscaping to reach the septic tank. A 2025 customer who could not be home said they pumped the tank, inspected it, left no mess, then sent a report and pictures a day later without trying to upsell. A 2025 reviewer said a pumping visit turned up an issue with the basement alarm system, which the company diagnosed as a float problem before recommending Hall Pump for the repair. A recent customer with a septic emergency said Ratta changed its schedule around to fit them in, then quickly diagnosed and resolved the issue. A 2026 customer said Rob Ratta and his team replaced their septic system and leach field. A 2025 customer said Rob and his team excavated and replaced a leaking underground water line, restored and reseeded the soil, and replanted a few shrubs. A 2025 customer said the office staff pushed the water testing company and the town inspectors to meet a tight closing schedule on a new septic system and Title 5 requirements. A 2026 customer said RM Ratta came right out for a clogged french drain backing up into the basement, a septic pumping and a portable toilet for a party. Its BBB grade is A+. A 2024 customer said they dug the hole and pumped the tank but left a mess, after being charged 140 for the digging. A recent reviewer wrote that a driver almost rammed into them and warned others to be careful on the road.
