About DON THERIAULT CONSTRUCTION

Don Theriault Construction in Azilda focuses on restoring failing leaching beds rather than digging them up. Its bacterial treatment is applied through a hand excavation about two feet square, which it says avoids heavy equipment and leaves little mess, and it can also be used on a working system to extend its life. A money back guarantee is offered. The company states more than 25 years in septic system services, installation, repair and design as a licenced contractor, and lists field bed repairs, field bed design and installation, excavation, and private and public sanitary sewer and water line work. An emergency response service handles sewage backups. Pages explain why systems fail and cover buying or selling a home with a septic system. Rated 5.0 from 3 Google reviews, with hours posted.
