Foundation Repair Cost can be cut by increasing pier spacings. Discount foundation repair companies will claim to save you money by installing less piers than you need.
The Foundation Performance Association has adopted standards for concrete cylinder pier placement along the exterior walls for residential construction. Below are few excerpt from the report:
Single story brick veneer house shall have piers spaced no more than 8 feet apart.
Two story brick veneer house shall have piers spaced no more than 6 feet apart.
When a porch, patio or dormer extends more than 3 feet, there shall be a pier/piling at each inside corner, each outside corner, and with separations not to exceed 6 or 8 feet as defined above.
Where a wall changes direction, a pier or piling shall be placed at each corner.
Interior pier spacing is 8 feet on single story and 7 feet on two story.
There is a lot more to pier placement than these excerpts, but by now you should get the idea.
Compare repair plans. Ask each company about the logic behind its pier placement.
We are not suggesting that every house exterior and interior needs to be wrapped with piers, but we are suggesting that a contractor can offer a cheap price by cutting out much needed piers.
