I have a listing with a stone foundation and it is scaring off several buyers. Although i have seen worse looking basements, i thought i would find more information to put some of you at ease.
missing or shifted stones, crumbling mortar cracks that run through multiple stones and areas of where the foundation is sinking
- every 100 years or so a stone foundation must be repointed, a process that involves chiseling old mortar away from accessible stone and replacing it with fresh material.
- repairing old stonework may require jacking up the house, re-laying the stones, bolting a wood or steel beam to sound portions of the old masonry or setting it on new steel posts
- to waterproof an older stone foundation, curtain drains may be installed.
- exterior curtain drains are effective, but cost $5,000 to $10,000 or more for a single wall.
- or install a sump pump.
- this fairly simple project costs less than $1,000, though adding a battery backup pump to work during power outages brings the price closer to $1,500.
It is best to consult a home inspector and or structural engineer about your home concerns.
