Since evictions do not appear on your credit report, a credit repair company will not be able to remove an eviction from your credit. If a credit repair company advertises that it can remove evictions from your credit, it is a good sign that you are dealing with a scam credit repair service.
Legitimate credit repair companies remove inaccurate information from your credit report and identify areas in which you can quickly improve your credit. You can do this credit-building work on your own too.
