Always get written estimates for any mobile home repairs you may be considering. Look for professional repair people that have experience specifically on mobile homes as well as have a good record of standing by their work. Ask for references and be sure to follow up.
Don't just use the first mobile home repair person you talk to, especially if this is a costly repair. Get three or more written estimates and compare what services, warranty and timelines the various companies are offering before deciding which professional can best meet your repair needs.
