These guys did the best job--and at the best price--of any plumbers or other household repair people that I've ever hired. They are fast, professional, courteous, and more than fair in their pricing. Discovering a leak coming through cinder block in my garage, I called Qualified Plumbing Services on a Friday morning in hopes of having the leak evaluated before the weekend. Within an hour, the owner, Mr. Parker, was at my house tracing the source of the leak, and within two hours, two of his employees had arrived and begun the extensive excavation process required to reach the leaking pipe. By extensive, I mean the use of a jackhammer and lots of digging were needed to create a hole underneath the house large enough for one of the plumbers to crawl in to, in order to make the repair. Once they had fixed the pipe, the workers removed the debris and poured fresh concrete over the hole, with the result that by the time they were done, one would hardly have known that they had ever been there... except, of course, for the repaired leak. The cost of this job, which required more than ten man-hours of hard labor and professional know-how, and which lasted until 7:00pm on a Friday? Just over $600 with the Angie's List coupon, a figure very much toward the low-end of Mr. Parker's original estimate, and about half of what I expected to pay. Based on my extraordinarily positive experience with Qualified Plumbing Services, I am happy to recommend them for any and all plumbing jobs.
