The answer to 'which is better rewiring or' is that rewiring is generally better than just replacing old electrical wiring in a home. Rewiring involves completely replacing the existing wiring system with new, up-to-code wiring that is safer and more reliable. This provides several benefits over just replacing individual wires or outlets, including improved safety, increased electrical capacity, and the ability to add new circuits and outlets as needed.
Rewiring is a more comprehensive solution that addresses the root issue of aging or inadequate wiring, rather than just treating the symptoms. It ensures the entire electrical system meets current safety standards and can handle the increased electrical demands of modern homes. While rewiring is more expensive upfront, it provides long-term peace of mind and protects the value of your home.
