"I claimed one of the “2 Toilet Tune-Up” Angi’s special with 4 Service Pros (Snell). When I contacted Snell I talked with a very nice lady who scheduled me to get 2 plumbers to come out the next day from Noon - 4pm. I was told they would call 20 minutes to 30 minutes before hand to let me know they were coming. I waited from Noon to 4:05pm, never received a phone call, and so I called Snell to find out if my plumbers were still coming. I was told that there was an emergency situation in Chantilly, VA, that required my 2 plumbers to go to Chantilly instead of my place that morning. I understand emergencies do happen, but Snell knew that my plumbers were needed for that major Chantilly, VA, leak from the morning. They should have called me once they found out that my assigned plumbers would not be able to come out to my place within my scheduled time appointment. I should not have had to wait from noon to 4pm and then have to call them to find out that they were not coming. I rescheduled with them, and set another appointment for the next day The next day Brandon Thomas came out, and he was outstanding. He is very friendly, professional, knowledgeable, efficient, and a very good plumber. My problems turned out to be quite different than I originally had thought and he explained my options. I went with the option that he recommended and am very happy with the results. He also gave me discounts to help make-up for my inconvenience for having to re-schedule the appointment. I definitely recommend Snell (4 Service Pros) to all my friends and family."

Stang Plumbing
Stang Plumbing
10 Employees. No subs. Cost is determined by the job itself. Service Fees Apply for certain equipment. Extra charge applies for after hours and weekend services.
"I contacted Stang Plumbing to give me an estimate on replacing the copper water supply piping (hot and cold) in my house with PEX A. Stang gave me a reasonable estimate right from the start. The two other estimates I requested further confirmed that Stang’s estimate was very reasonable and after they promptly responded to several questions I had concerning their proposal, I chose them to do the work. The workers showed up promptly on the first day to start the work and every day thereafter. The lead plumber, Rob, did a great job of communicating the progress at the end of the day and what he intended to accomplish the next day. Each day Rob made sure that water service was restored through out the house and that there were no leaks from the work that had been performed. The piping replacement was completed on the schedule originally proposed. Rob, and his helper Mark, were very professional and courteous and a pleasure to deal with. I will happily chose Stang Plumbing for any future work and highly recommend them for any plumbing services you may need."
