I run excavation jobs across the New Hampshire Lakes Region from a shop in Hill, which sits roughly in the middle of everything. Newfound to the north, Webster Lake and Franklin to the south, Squam and the Pemi corridor to the west, Winnipesaukee shoreline to the east. Most weeks I'm somewhere on Route 3A, Route 104, or the back roads off them, working a foundation, a septic replacement, a driveway rebuild, or a drainage fix. Every lake and every corridor has its own quirks, and the work has to fit them.
I'm a solo owner-operator. The same person walks the site, runs the machine, and writes the estimate. Fifteen-plus years working Lakes Region land. NH Business ID 878196.
What "Lakes Region excavation" actually covers
The work splits into a handful of categories that show up over and over across every town in the region:
- Foundations and site prep. New builds on cleared upland lots, rebuilds and additions on older year-round housing, foundation work on lakefront homes converting from seasonal to year-round.
- Septic excavation. Replacing older lakefront systems, new installs on buildable lots, repairs on systems that have failed or are about to. The licensed designer handles the design and the state permit under RSA 485-A; I handle the dig.
- Driveway construction and grading. New gravel installs, washout repair after spring melt, regrading when the pitch is wrong, base prep that holds through mud season.
- Drainage and curtain drains. Foundation drainage on older homes, curtain drains on hillside lots, regrading to pitch water away from buildings, perimeter rock beds. Lakes Region groundwater is high in spring and the soils don't always drain well.
- Utility trenches. Buried propane and oil-to-propane conversions, water and power lines, septic effluent runs. Everything goes deep enough to clear the four-foot NH frost line, with proper bedding and lift-compacted backfill.
- Lot clearing and site prep before the dig. Brush, small trees, and stumps cleared off a buildable lot before excavation starts. More on lot clearing & site prep →
The waterbodies and what excavation looks like on each
The Lakes Region is named for its lakes, and the lakes shape the work. Each one has its own setback rules, its own access patterns, and its own typical job mix. Here's how it breaks down.
Newfound Lake (Bristol, Alexandria, Hebron, Bridgewater)
Newfound is a public water body covered by NH's Shoreland Water Quality Protection Act, RSA 483-B. The first 250 feet of shoreland from the reference line carries real restrictions on excavation, tree removal, and impervious surface. The first 50 feet (the Waterfront Buffer) is even tighter. Inside that envelope, work is permitted but sequenced carefully. Equipment stages outside the buffer where possible, and shoreland permits get pulled before the dig when the scope requires them.
The most common Newfound excavation jobs: septic replacement on shoreline camps still running 70s and 80s systems, driveway rebuilds on the steep camp drives off the shoreline roads, foundation work on year-round conversions, and drainage fixes on lots that handle a lot of spring runoff from the surrounding hills.

Squam Lake (Holderness, Center Harbor)
Squam falls under the same RSA 483-B shoreland framework as Newfound, with similar 250-foot and 50-foot buffer rules. The difference is the Squam side tends to see stricter local-level oversight on top of state rules. Local conservation commissions are active, and the housing stock is a mix of generational family camps and high-end residential. Access is often steep, lots are sometimes large, and the right answer to "can a big machine fit" is frequently no. A smaller excavator with the right operator does more on a Squam lot than a bigger one would.
Most common Squam jobs: septic excavation on long-tenure family camps where the system predates the current setback rules, foundation work on additions that thread the buffer rules, and drainage on the steep approach driveways.
Winnipesaukee shoreline (Meredith, Gilford, Laconia, Center Harbor)
Winnipesaukee is the largest lake in NH and gets the heaviest shoreland scrutiny under RSA 483-B because of its size and the development pressure around it. The 250-foot and 50-foot buffer rules apply the same way they do on Newfound and Squam, but enforcement is more visible on Big Lake because the property values are higher and the inspections are more frequent. The work on Winni shoreline jobs is usually high-end residential: foundation upgrades, year-round conversions, driveway and grading work tied to landscape projects, septic upgrades on older camps.

Webster Lake (Franklin)
Webster Lake sits inside the city of Franklin and falls under RSA 483-B as a public water body. Webster has fewer shoreline lots than the bigger lakes, and the housing is closer to a true year-round mix than to summer-camp prevalence. The Franklin side of my service area also includes Three Rivers Junction, where the Pemigewasset, Winnipesaukee, and Merrimack rivers meet. Excavation in that corridor sees groundwater that comes up fast in spring and stays high. Older shoreline septic systems past their design life are common. Excavation in Franklin, NH →
Pemigewasset River corridor (Plymouth, Ashland, Bridgewater, Hill)
The Pemigewasset is an RSA 483-B public water body. The setbacks read 250 feet from the reference line, 50 feet for the waterfront buffer, and septic separations of 75 to 125 feet depending on soil. The Pemi corridor is where the Lakes Region transitions into the White Mountain foothills, and the soils transition with it: more glacial till, more ledge, steeper grades on the back roads. Plymouth itself is the largest town in the corridor and sees foundation, driveway, and drainage work tied to both the historic downtown housing stock and newer development off the Tenney Mountain corridor.

What makes the Lakes Region different from southern NH
If you're comparing quotes from a southern NH or Seacoast excavator and one from a Lakes Region excavator, a few things are genuinely different up here:
- Shoreland regulations. RSA 483-B applies anywhere a public water body is within 250 feet, which in the Lakes Region is a lot of properties. A southern NH dig usually doesn't have to deal with shoreland permits at all. A Lakes Region dig often does.
- Soils. Glacial till with ledge boulders showing up in unexpected places. Some lots have pockets of better-draining sand or sandy loam, especially toward the Pemi corridor and the Bristol uplands. Other lots are mostly stone. The difference moves cost.
- Frost line. Four feet typical, sometimes deeper on exposed lots in Plymouth, Ashland, and the upper Pemi. Foundations, water lines, and septic effluent runs all need to clear it.
- Mud season. March and early April. The frost is leaving, the ground is saturated, and dirt roads are under posted weight limits. Most foundation excavation pauses during this stretch. Septic and drainage can sometimes start earlier depending on access.
- Distances. The Lakes Region is geographically larger than a single suburb. From Hill to Holderness is about 30 minutes, Hill to Gilford about 35, Hill to Bristol about 15. Travel is built into how I schedule the week, not into every estimate.
What I do on a Lakes Region site visit
The site visit is free and there is no obligation. I walk the work with you, ask questions about scope and timeline, look at access, soils, shoreland setbacks if the lot is near water, and any constraints the previous contractor missed. You get a written estimate within a few days that's itemized and honest about what could move the number once the dig actually starts. If shoreland permits are needed, I tell you that up front and walk through who pulls them. If there's something about the lot that affects price, like ledge or high groundwater or a long machine route, I tell you in plain language so it's not a surprise.
Common questions from across the Lakes Region
What towns are in your Lakes Region service area? All of the obvious ones (Bristol, Plymouth, Franklin, Laconia, Meredith, Gilford, Holderness, Ashland) plus the smaller ones (Sanbornton, Belmont, Tilton, Northfield, New Hampton, Andover, Hebron, Bridgewater, Alexandria, Center Harbor). If your town isn't on this list, call. Most weeks I'm passing through it anyway.
How do shoreland setbacks affect cost? The setbacks themselves don't add a fee. What adds time and cost is the sequencing: more erosion control, sometimes smaller equipment for tight access, and a Shoreland Permit pulled before the dig starts when the scope crosses the threshold. I price it honestly in the estimate.
Do you handle older lakefront septic systems? Yes. This is one of the most common excavation jobs I run. The licensed designer draws the new system and pulls the state permit. I handle the dig, the bedding, the tank set, and the final cover-and-grade.
What about excavation in winter or mud season? Frozen ground in January and February is fine for some jobs (clean access on otherwise soft sites, stump pulls without summer rutting). Mud season in March and early April is the hardest stretch, and most foundation work waits until late April or May. Septic and drainage can sometimes start earlier depending on the site.
