If within five (5) years of the date of work, water infiltration reoccurs at the same location patched by KELLIN, and such recurrence is caused by defects in materials used by KELLIN, or by the failure of KELLIN to apply the materials in a workmanlike manner, KELLIN shall, at its own expense, re-patch the previously treated area to the extent necessary to prevent further water infiltration. 2. In addition to the provisions of paragraph 1 hereof, in no event shall KELLIN be responsible for any reoccurrence of the infiltration which is caused by additional settling or movement in the foundation or any part thereof. 3.
