Another septic system successfully brought back to life!

When a septic system reaches the end of its service life, the best long-term solution is a new replacement system —not just another repair. On this project, our crew removed a failed EnviroSeptic system and installed a brand-new conventional stone and pipe leach field, designed to provide the homeowner with years of dependable performance.

The project included:
✔️ Excavation and removal of the existing failed EnviroSeptic system
✔️ Careful site preparation of the new leach field area
✔️ Installation of new distribution piping and distribution box
✔️ Placement of washed stone and a new stone & pipe absorption system
✔️ Final grading and restoration of the property

Every septic installation starts with proper excavation and precise elevations. Taking the time to build the system correctly ensures even wastewater distribution, proper drainage, and a longer-lasting septic system.

Whether your current septic system is failing or you’re building a new home, David O’Neil Construction has the experience and equipment to handle your project from start to finish.

📍 Proudly serving Cheshire County and the Peterborough area.

📞 Call our office today at 603-876-9000 to discuss your septic replacement or new installation project.

Driveway Season is in Full Swing! 🚜

We’ve been busy completing several driveway projects, and one thing never changes—a great driveway starts with a great foundation.

At David O’Neil Construction, we believe the key to a long-lasting driveway is building a solid, properly compacted gravel base before applying the final surface. A strong base provides proper drainage, reduces settling, and helps prevent ruts and potholes over time.

One of our most popular finishing options is asphalt grindings (millings). Asphalt grindings offer several great benefits:
✔️ Cost-effective compared to new asphalt
✔️ Creates a durable, hard-packed driving surface
✔️ Helps reduce dust and loose gravel
✔️ Holds up well to everyday traffic
✔️ Recycles existing asphalt, making it an environmentally friendly option
✔️ With proper compaction and time in the sun, it binds together to create a smooth, low-maintenance surface

Whether you’re replacing an old driveway or building a new one, taking the time to install the right base makes all the difference in how your driveway performs for years to come.

If your driveway needs an upgrade, we’d be happy to provide an estimate.

Big progress on this house lot project in Nelson, NH! 🚧

Our crew has been hard at work digging and prepping the site for the foundation—carefully excavating, grading, and setting the stage for concrete basement walls. Precision is everything at this stage, and we’re making sure the base is solid and ready for the next phase.

From raw land to a future home; it’s always great to see a project start taking shape.
