Faulty wiring is never a DIY repair. It's best to hire a professional electrician to assess the problem and begin repairs so that your home is safe and your electrical system works properly. If cracks in the foundation are suspected, a structural engineer should inspect the house to determine the extent of the damage and recommend a plan to fix it. Your builder may be able to fix the damage in several ways, such as steel braces bolted to the house, helical screws, or concrete pillars.
In extreme cases, a new base may be necessary. It's important to get a permit for any remodeling project, as it safeguards you legally and financially, and ensures that all city codes and codes for each part of the project are met and maintained. When remodeling an old house, it's important to be aware of potential plumbing or electrical problems. If you find any, it's best to hire a professional plumber or electrician who is licensed by the state and knows up-to-date codes and standards.
A licensed professional can help with more difficult projects such as creating a new bathroom, installing plumbing in a laundry room, adding a shower or bathroom, or installing plumbing in a new or remodeled kitchen. Faulty wiring can create unsafe working conditions for contractors and delay the remodeling project. Make sure that a professional performs necessary electrical repairs before resuming your remodeling project. If you're remodeling your entire home, make sure you have a safe place to stay while the work is completed.
Building codes change over time, so your renovation project may reveal that your electrical and plumbing systems don't meet current codes. It's best to hire a professional for sensitive electrical, HVAC, and plumbing jobs.
