Question

What does a sill plate do?

Community Answer

The sill plate transitions between the foundation and the wood framing of the walls. The sill plate is treated to act as a barrier, keeping out termites and other critters, and keeps moisture from getting under the wall framing and causing water damage. The sill plate is also what you attach your framed walls to. Always wear proper safety gear when using power tools. Also a clean work site is a much safer work site.

Question

How much distance is needed between J bolts on a 16 foot board?

Community Answer

J bolts should be a minimum of 2 ft on center to attach a sill plate to the foundation. Check your local building code, as this could differ from state to state or city to city. Your city planning department should provide you with all the building code information you need when applying for a permit.

Question

How do I go about underpinning a foundation?

Community Answer

You don't. You call a foundation repair specialist company that's done it numerous times and can give you references as well as a license number and proof of insurance.
