Garside Sewer & Septic Service LLC

Garside describes itself as a family-owned and operated septic company that has served New Hampshire residents for over 40 years, with septic system installation, pumping, cleaning, inspection, certification, repair and fracturing in southern New Hampshire. Its stated service area includes Bedford, Derry, Hudson, Londonderry, Merrimack, Nashua, Pelham and Windham. A recent customer said Zach came out on a weekend emergency call for a septic that had backed up, found a blockage in the waste pipe leaving the house and used his hose to suck it out. That customer also said they plan to schedule work on Zach's suggestion to replace a pipe. A recent customer who has used them exclusively for 20 years called them very professional and responsive. In a 2023 review, a customer who bought a house with a septic that hadn't been pumped in years said the owner himself drove the truck and did the service. That 2023 customer said he explained how the tank was functioning and got special risers for the tank the same day so it didn't have to be dug up again. A 2023 customer said Keith showed up within 10 minutes of a Saturday-evening call about a septic backing up into the bathrooms, basement and attached garage, and quickly diagnosed and fixed the issue. That 2023 customer called the pricing for the Saturday-night emergency call fair and reasonable. A 2024 customer said Keith advised them a Sunday emergency could wait until a work day to avoid weekend charges, was there by 8:30 am and returned later to fix the issue. A 2025 customer said Keith came out to look at a septic issue and opted for a less expensive repair. A 2023 customer said the company stopped responding to emails and never answered back after a request to schedule a service.
