NN7
The Porous Stone Protocol: Non-abrasive cleaning for the limestone belt.
As you move south into NN7, the geology shifts to limestone. This stone is soft, porous, and prone to 'Green Algae' in the humid Nene Valley. Pressure washing destroys it. Our stewardship here is strictly non-abrasive. We use a 'Bio-Cidal Foam' that dwells on the stone, killing the algae at the root and allowing the rain to wash it away gently over time.

Connecting NN4 to the NN12 Towcester corridor, NN7 requires Soft Washing and Heritage Restoration to preserve the character of these high-value commuter villages.
