Waterproofing a basement in Chatham
Chatham sits at the elbow of the Cape, surrounded by water on three sides, with shingled capes and summer cottages from its fishing-village past.
Near the sound, Pleasant Bay, and the ocean and in low areas, groundwater can rise after heavy rain. In Chatham, we start with the outside, gutters and grading, and add an interior drain and a sump pump only where the water keeps coming in.
Much of the Chatham shoreline is in FEMA flood zones, and the town is extending sewer neighborhood by neighborhood. A sump pump drains into neither the sewer nor a septic system, so we plan the discharge line to run outside, away from the foundation, whichever one your street has.

Waterproofing permits in Chatham
We prepare the drawings, file the applications, and schedule the inspections. Here is what a project like this usually needs:
- Electrical permit for a new sump pump circuit, pulled by a licensed electrician.
- The Chatham Conservation Commission review if digging is within 100 feet of a wetland, coastal bank, or the shore.
- Inspection to find where the water gets in
- Gutter, downspout, and grading fixes
- Foundation crack and pipe gap sealing
- Interior perimeter drains
- Sump pumps with battery backup
- Exterior waterproofing and footing drains
- Moisture control before finishing
- Permits where the work needs them
Basement Waterproofing in Chatham: FAQ
Do you waterproof basements in Chatham Village and North Chatham?
Yes. We waterproof basements all over Chatham, including Chatham Village, North Chatham, South Chatham, West Chatham, and Chathamport. Our base in South Yarmouth is about 13 miles away.
My Chatham basement takes on water only in big storms. What helps?
Start outside, with gutters, downspouts, and grading. If storm water still comes in at the base of the walls, an interior drain with a sump pump and a battery backup handles it, since storms are also when the power goes out.
Can a sump pump drain into my septic system?
No. A septic system is built for wastewater only. The discharge line runs outside, away from the foundation and the leach field.
