Hired this company to remove/replace a leaking fuel tank on my boat. Their personnel are completely knowledgable,totally focused on the task, take no shortcuts, do everything needed for A-1 work, and everything was done ON TIME. Their work is impeccable. I would hire them again and cannot recommend them highly enough. If you have questions about them do NOT hesitate to call me as I will tell you exactly how they handled my scenario and I do not mind bragging about them. They are ACES in my estimation......Neil Truka (949) 813-2822
