Kittery basement waterproofing — local context
If your Kittery basement keeps taking on water, the town's geography is usually the reason. Per Wikipedia, Kittery is a low coastal town where roughly 76% of its area is water and the land sits near sea level between the Gulf of Maine and the Piscataqua estuary, drained by tidal Spruce, Spinney, and Chauncey creeks. The Piscataqua Regional Estuaries Partnership reports that as tides rise and stormwater backs up through the 9.5-square-mile Spruce Creek watershed, flooding is becoming more common. Underneath, USDA-NRCS maps poorly drained Scantic and moderately well-drained Buxton soils — fine marine clays that hold water against a foundation instead of letting it drain. As Maine's oldest town (incorporated 1647, per kitteryme.gov), Kittery also has plenty of old fieldstone-foundation homes — our specialty. For those conditions we install an interior Forever Dry System: a full-perimeter drain, a sump per 120 ft, a wall vapor barrier, and a dehumidifier, kept healthy with annual drainage maintenance. Basement waterproofing runs $3,000–$30,000.
What a recent customer said
I hired 603 to waterproof my basement at the beginning of spring this year. They were a little on the pricey side but the work came with a lifetime guarantee and we haven't had any water issues in the last 6 months. Communication was great all the way through and they were in and out in 3 days.
Frequently asked questions
Why do Kittery basements flood so often?
Kittery is a low coastal town — per Wikipedia, about 76% of its area is water and the land sits near sea level between the Gulf of Maine and the Piscataqua estuary, drained by tidal Spruce, Spinney, and Chauncey creeks. The Piscataqua Regional Estuaries Partnership reports that as tides rise and stormwater backs up through the 9.5-square-mile Spruce Creek watershed, flooding is becoming more common. Low, tide-influenced ground keeps groundwater high against foundations.
What kind of soil is under Kittery homes, and why does it matter for a wet basement?
USDA-NRCS Official Series Descriptions map Kittery's coastal lowlands as poorly drained Scantic and moderately well-drained Buxton soils, both formed in fine-textured glaciomarine and glaciolacustrine deposits. Poorly drained marine clay holds water against a foundation rather than letting it drain away — which is exactly the condition an interior perimeter drainage system is built to manage.
Do you waterproof old fieldstone-foundation homes in Kittery?
Yes. Kittery is the oldest town in Maine (incorporated 1647, per kitteryme.gov), so its housing stock includes some of the oldest homes in the state, many on fieldstone foundations — our specialty. We install an interior Forever Dry System: a full-perimeter interior drain, a sump per 120 ft, a wall vapor barrier, and a dehumidifier, rather than exterior excavation.
