Why Jamestown Homeowners Choose Aqua Solutions
Jamestown is a borough of about 683 residents in Mercer County, set inside Greene Township (population about 1,032). The borough sits in glaciated northern Mercer County immediately beside Pymatuning Reservoir and Pymatuning State Park, which dominates the regional hydrology. Combined with the local glaciated soil setting (recurring Ravenna, Frenchtown, and Canfield map units in Mercer County), bedrock in the Cuyahoga Group and Cussewago Formation, and an older small-borough housing stock, basement moisture is a recurring concern for properties throughout the borough and surrounding township.
Jamestown sits in the Pymatuning area of northern Mercer County. The published geology and groundwater framework for this part of the county is documented in the USGS Pennsylvania Bureau of Topographic and Geologic Survey report on northern Mercer County, with USGS Mercer County observation well MR 3306 (120 ft, completed in the Cuyahoga Group) showing recent water levels in the mid-20-foot range in 2025. Recurring Mercer County soil series include Ravenna silt loam (somewhat poorly drained, hydrologic group D), Frenchtown silt loam (poorly drained, group D), and Canfield silt loam (moderately well drained, group C/D). Recent USGS Pennsylvania reporting notes that bedrock observation-well depths do not rule out shallow perched water at the parcel scale, so seepage profiles vary noticeably from one Jamestown property to the next.
About Jamestown, PA
- Population
- 683 (borough, ACS 2024 5-year); ~1,032 across Greene Township; 356 housing units in the borough
- Housing Stock
- Small-borough housing stock in the 356-unit borough core, plus 503 housing units across Greene Township; older homes typically on stone or early concrete-block foundations, newer construction more often on poured concrete
- Soil Conditions
- Recurring Mercer County soil series: Ravenna silt loam (somewhat poorly drained, hydrologic group D), Frenchtown silt loam (poorly drained, group D), and Canfield silt loam (moderately well drained, group C/D); township-boundary-specific acreage ranking still to be confirmed from USDA NRCS Web Soil Survey AOI export
- Annual Rainfall
- Approximately 42 to 44 inches per year in glaciated northern Mercer County (per NRCS soil series climate context and regional Mercer County climate normals); a Jamestown-specific NOAA station ID is pending verification against the NCEI 1991-2020 normals
- Water Table Depth
- Bedrock observation well USGS MR 3306 (Cuyahoga Group, 120 ft deep, ~9 miles from Jamestown) shows recent water levels of 25.27 ft below surface (July 2025) to 25.66 ft below surface (December 2025). That bedrock value does NOT rule out shallow perched water on Jamestown parcels, especially on lower lots near the reservoir or in poorly drained Frenchtown/Ravenna soils where seasonal water can sit within inches of the surface

Jamestown Waterproofing Questions Answered
Common questions from Jamestown homeowners. Can't find your answer? Call us.
Does Pymatuning Reservoir cause wet basement problems in Jamestown?
The reservoir watershed elevates lateral water pressure on lakeside and creek-adjacent foundations, and Pymatuning State Park's drainage system shapes runoff across the surrounding township. Borough homes set back from the immediate shoreline are less directly affected but still inherit the regional water table, soil drainage characteristics, and seasonal recharge patterns of the broader Pymatuning landscape.
What soil conditions drive wet basements in Jamestown?
Mercer County's recurring soil series include Ravenna silt loam (somewhat poorly drained, hydrologic group D), Frenchtown silt loam (poorly drained, group D), and Canfield silt loam (moderately well drained, group C/D). Group D soils are the slowest-draining classification and produce significant runoff, hydrostatic pressure against foundation walls, and slow-to-drain footing zones. A township-specific Web Soil Survey export will identify the exact map unit on your lot.
What foundation types are common in Jamestown homes?
Jamestown is a small borough with 356 housing units in the borough core and another 503 across Greene Township. Older homes (especially in the borough core and around Pymatuning State Park) typically have stone or early concrete-block foundations not engineered for modern hydrostatic loads. Lakeside vacation homes converted to year-round use often need crawl-space encapsulation. Newer township builds more often have poured concrete.
How do groundwater levels around Jamestown actually behave?
The closest verified USGS observation well (MR 3306, completed in the Cuyahoga Group at 120 feet, about 9 miles from Jamestown) shows recent water levels in the mid-20-foot range. That is bedrock-level data, not the shallow perched water that actually affects basements. Parcel-scale shallow water can sit within a foot of grade in poorly drained soils, especially during spring snowmelt and reservoir-watershed recharge.
What does basement waterproofing cost in Jamestown, PA?
Costs depend on basement size, soil conditions, and the severity of the water problem. Interior French drain systems for a typical Jamestown home run $3,000 to $8,000. Full perimeter systems with sump pump and crawl-space encapsulation can run $8,000 to $20,000 or more. Lake-margin and reservoir-adjacent properties often need additional exterior drainage. We provide free in-home estimates with itemized pricing.
Can a sump pump handle a Jamestown lakeside or near-reservoir basement?
Sometimes, but in reservoir-watershed conditions a layered system usually does better. That includes interior drainage to capture seepage, a sized sump basin and pump (often with battery backup given regional storm patterns), exterior grading and downspout corrections, and crack injection or wall reinforcement where movement is present. We diagnose what your specific Jamestown property actually needs.
