Purchase surety bonds. Surety bonds essentially act as a kind of agreement between the contractor and the person hiring them that the job will be performed to standard. You can obtain these through your current insurer as a separate form of financial protection. As a contractor, many states require you to be bonded before you can begin working legally.
I have a few properties and I always call Kamco for any work I need for the roofs or any leaks and odds and ends that the properties may need. They are very responsive! They are prompt and reasonable with their price. They are a very busy company but always make time even if you must wait a few days it’s worth it because they are great at what they do. I have been using them for over 7 years and am very happy! Thank you Kamco Family!
