At Northeast Site Works, we’re a local New Hampshire excavation company that homeowners trust to get the job done right. From driveways and backyard pools to foundations and site prep, we bring experience, care, and attention to detail to every residential project—treating your property like it’s our own.
From concrete work to underground utilities, we provide complete site work solutions backed by decades of experience

We offer a wide range of residential concrete services in New Hampshire including foundations, driveways, patios, and flooring. We work closely with our clients to ensure that their project is completed to their exact specifications, and we are there every step of the way to ensure a successful outcome.
Driveways can be a focal point of any home, and we offer driveway repair solutions to address any problems that may arise. If the concrete is still structurally sound, we will repair it instead of replacing it, saving our customers a significant amount of money.
Outdoor decorations, designs, and appearances are important because they add value and curb appeal to a property. We make sure that our concrete patios surpass our clients' expectations in terms of quality, beauty, and longevity. Our concrete contractors can turn your vision into reality, whether you want a modern concrete patio design or a completely custom look.
Concrete may not be the most visually appealing material, but stamped concrete can give it the look of natural stone, brick, or pavers. This is a more affordable and cost-effective way to improve the appearance of any property, and it is also low-maintenance. Stamped concrete can add aesthetic appeal and value to any outdoor space.
Saving the existing concrete is often the most economical way to provide a level and safe surface. Leveling a concrete slab before it becomes too damaged can extend its lifespan for many years. Our team will evaluate the concrete to determine whether it can be repaired or replaced.
We excel in our methodical approach to installing gravel driveways. Initially, we focus on precise grading to ensure effective water drainage. Following this, we select the optimal gravel, tailored to the specific environment, to ensure both durability and aesthetic appeal. The outcome is a robust and attractive driveway that enhances the value of any property.
If your gravel driveway or recycled asphalt driveway isn't looking as good as it used to, or if you need to repair cracks & erosion caused by difficult weather conditions look no further than our Gravel Driveway Services. Servicing New Hampshire and surrounding areas, no job is too big or too small. Contact us today to get a quote and discuss your upcoming project.
