Editorial summary
ONYX FOUNDATION is listed in Arlington as a foundation repair contractor, though the Google category in the source is construction company. The record confirms crawl space repair and foundation repair, and the business carries a perfect 5.0 Google rating from 6 reviews. That is a positive signal, but the sample is small, so it should be read cautiously. There is no website in the source, and no years in business or service-area text are supplied. For homeowners, the useful part of this record is the direct connection to structural repair work below and around the home. Crawl space repair often comes up when floors feel uneven or when moisture and structural concerns overlap, but the listing does not spell out any specific methods. Because the profile is compact, it is best treated as a basic directory entry rather than a full service page. Readers looking for deeper scope details will need to call and verify what the company handles.
