Welcome to Main Ex



MainEx is an earth excavation company with our home office located in Augusta, Maine.  Commercial and residential projects are both performed with the same focus: an attention to details and a solid commitment to customer satisfaction. MainEx strives to provide the highest quality of workmanship in a competitive manner while maintaining a safe and environmentally sound work place for all.  

MainEx performs projects for general contractors and homeowners across the central Maine area. We primarily concentrate our efforts in the Kennebec County area, but are willing to travel to adjourning counties to accommodate our customer's needs. Our projects range in size from complete residential sites to large commercial buildings.  MainEx also works closely with local utility districts to install new water and sewer main lines, as well as repair or install catch basins and manhole structures. 

MainEx is fully insured and bonded. Specialty insurance is readily available, if a particular project requires it.  We work closely with our agent and the owners to be sure we meet or exceed a project’s insurance requirements.

MainEx also has several employees who are certified in DEP erosion and sediment control practices. This allows all of our jobs to be environmentally compliant, and enables us to be able to anticipate potential concerns before they develop.  This training makes MainEx qualified to work on any project within delicate shoreland zones of Maine.

We are proud to have an extremely knowledgeable team.  Most MainEx employees are 10 or 30 hour OSHA trained.  We have members that are also Flagger Certified, and all members are taught the benefits of defensive driving through routine safety meetings. 

MainEx is proud to be a pre-qualified contractor with the Maine Department of Environmental Protection for petroleum contaminated soil excavation since 2010.  This is a process in which a company’s past work experiences, their safety training and general business practices are highly scrutinized by a team of DEP experts. To stay qualified, we must maintain our team’s HAZWOPPER training, maintain a high standard of workmanship and abide by all environmental regulations.  MainEx proudly continues to be included on this selective list of contractors.

Our team is focused, knowledgeable and all MainEx members understand the value to the owner when a project moves forward efficiently.  MainEx is capable of accomplishing all of your excavation specifications in an efficient, safe and professional manner, and we look forward to helping you exceed your goals.
