Building standards have changed significantly, and many homes in Amherst were constructed before modern codes were established. In older homes, support beams may be undersized or support posts spaced too far apart, particularly in crawl spaces that were never designed for long-term durability. This places additional stress on the floor system and increases the likelihood of sagging over time.
Homes more than 50 years old may also contain materials that were never intended to last indefinitely. Builders often used wood shims to level framing during construction. As these shims age, they compress or decay. At Acculevel, we replace failing shims with steel shims to prevent compression and improve overall load distribution.
