Why Gilmanton Basements Get Wet
A Gilmanton farmhouse cellar is a different animal from a modern basement and should be judged by different standards. Dry-laid fieldstone, an earth or partially poured floor, and a level of ambient damp that has been there since the house was built. Some of that is normal — these were root cellars and storage, not living space, and they were built to breathe.
What is not normal is standing water, water arriving in volume during a melt, active washing of soil from between stones, or a noticeable change in a cellar that used to be dry. On ridge-and-hollow ground the usual culprits are surface water and grading rather than a rising table: roof runoff dumped at the foundation, ground sloping toward the house after decades of settling, or a seasonal seep on the uphill side.
Those are fixable from outside and comparatively cheaply, which is why we always look at grading and gutters before proposing anything expensive on a Gilmanton cellar. And where repointing is genuinely needed, it must be a lime-based mortar — hard modern mix on antique stonework causes its own damage.
Gilmanton Note
On a Gilmanton farmhouse cellar, start outside. Roof runoff at the foundation and ground that has settled to slope toward the house cause more wet cellars in this town than anything happening below grade.
