Hello everyone, We just had a big plumbing problem, and used RDN Plumbing. I found out about them through the referral list provided from this site. They were really great, and we would use them again. They were prompt, reasonable price, pleasant, left everything clean when finished, and most important did a fantastic job. Our plumber was Joe and he told me that he usually does most of the Highland Park work. RDN Plumbing 412-462-1435 1060 Forest Ave West Homestead,PA 15120 Kind regards, Rebecca & Esko Polvi
