Wet Basements in Gilford, NH

Gilford runs from the Winnipesaukee shore up the flank of the Belknaps, and basements at the two ends have opposite problems. Down on the water, the issue is a high water table. Up on the hillside, it is water arriving from above — springs, seasonal seeps and runoff moving downslope through the soil.

Why Gilford Basements Get Wet

Hillside properties in Gilford deal with a problem that lakeside houses never see: water moving laterally through the ground. On sloping terrain in the Belknaps, snowmelt and rain do not simply soak down — they move downhill through the soil above the bedrock and encounter whatever is in the way. If that is your foundation's uphill wall, you have a seasonal spring running against it every March.

The signature of that is water appearing on one wall only, the uphill one, and appearing reliably in the same weeks each year. It is a grading and drainage problem far more often than a foundation problem, and the solutions start outside the house rather than inside it.

Down on the shoreline, the picture reverses: a water table that rises with the lake, water arriving through the floor-wall joint, and seasonal properties whose foundations were built for summer use. Gunstock-side properties add the runoff volume that comes with elevation and a hard spring melt.

Gilford Note

If water shows up on one wall of your Gilford hillside basement and always the same wall, look uphill before you look at the foundation. You probably have a seasonal spring, and the fix is usually grading and drainage outside rather than anything done to the wall.
