What a great find! We live in an older home with older pipes. These guys are real plumbers. They have been around for a long time and are clearly very skilled and experienced, and able to handle any job, any situation. Albert was the plumber that came and responded to the call with our severely backed up sink. He was kind, courteous, professional, and got the job done right. He also gave us a very fair price for the work he did. I would recommend WJ Maloney Plumbing Company to anyone in need of Plumbing work. Two thumbs up, and five stars for these guys!

They replumbed my house and did a phenomenal job. Not only were they professional and good at their job, they were clean, neat, and worked to the highest quality. I would easily hire them again for any other plumbing job.
