Septic Designs of NH, LLC

Septic Designs of NH holds 5 stars from 130 Google ratings and an A+ grade from the Better Business Bureau. The company says that during an inspection it walks customers through what it will do and why, and answers their questions before it leaves. A recent customer said the company designed a new septic system, secured the permits and finished the design faster than expected. A 2026 customer working through a Durham septic permit wrote that the company received State and Town approval in less than 10 days, covering the design layout and permitting application. A 2025 customer said the soils test was done, the design completed and the plans submitted to the State, with approval the same day. A recent customer said they re-lined a sewer pipe and were in and out in a few hours. A 2026 customer said they lined the drain lines of a 1960s ranch home underneath the basement slab. A recent customer said the company fixed a broken pipe, dug up and removed a plant, and was careful putting it back. A recent customer said the inspector, Chris, explained everything about their setup and was patient with their questions. A recent reviewer said the tech scoped their septic line for a possible lining, which turned out not to be needed, at a reasonable price. A 2025 customer said the company inspected the septic system before closing on a lakefront home in New Hampshire and had the detailed inspection report ready within 24 hours; that customer named the owner as Micah Denner. A 2023 customer said the company installed a new tank, hooking into the existing system, for a small cottage being built, and believed the installation side of the company is Rock Solid LLC. In a 2020 HomeAdvisor review, a customer said Zach and Chris brought jetting equipment and cleaned out a large root that was blocking the pipe.
