"Bob the Builder was a blessing to my family. After getting no where with other contractors and dealing with the insurance company. Bob the Builder step in and handled everything that needed to be done to get my mother’s house repaired. Me and my siblings were searching to find a contractor to repair my mother’s house since December 2020. We even asked our insurance company for recommendations but those contractors gave us the runaround. When we hired Bob the Builder they gave us outstanding customer service and kept us updated on everything. If you are looking for a trustworthy contractor, Bob the Builder is that contractor.
