I have used Jim Lozar for many of the different plumbing issues that have occurred during my care and maintenance for my senior friends' homes and rentals the last several years. Jim has proven very timely, very knowledgeable, helpful, courteous with them in fixing their plumbing issues. I now count on him doing very professional work because of my experience with his work skill, his knowledge and pleasing personality. When I call and have to leave a message, I know he will call back that day or within 24 hours and let me know his availability.
