Commercial drain cleaning is offered for restaurants, hotels, apartment buildings, hospitals, offices, and industrial facilities, using free video inspections, free second opinions, high-pressure jetting, sewer snaking, line location, and no-dig pipe patch repair for broken pipes, tree root intrusions, and pipe separations. Electrical services center on panel upgrades, including SPAN smart panels, and electric vehicle charger installation, with whole-home electrical work such as new circuits and troubleshooting. Seasonal camp services cover winterization and openings.

The business sits on Roosevelt Trail, about half a mile from the highway of the same name and from Gray Road. Black Brook Preserve is roughly 0.4 miles away, Nash Hill about 0.6 miles, and Windham Town Hall about 0.7 miles.
