McMullen Septic Service, Inc.
McMullen Septic Service, Inc.
At McMullen Septic Service, Inc., we are your premiere source for septic system work. Our company offers the finest service for pumping, inspection, installation & repair. We generally offer same day/ next day service for your pumping needs. We have been a family owned and operated business serving Sussex and Kent county and surrounding regions since 1953. When it comes to professionalism and customer service, we are unmatched in the region. For the best of the best, call today for your next project.
"At the time I made the appointment I told I could pay by credit card however after they were done I was told I had to pay by check or cash. I called the following day to express my displeasure and to point out that not everyone has an extra $325.00 available at any given time. I spoke with one of the owners. He refused to even acknowledge they were in the wrong and instead made excuses as to why his employee couldnâ t use my WiFi to accept the credit card payment. He was extremely rude and very condescending. Instead of apologizing for their miscommunication he actually hung up on me. It appears as if this is another company that had its good reputation built by the father but has now been taken over by his spoiled son who has zero business sense and horrible customer service. I would not recommend them."

Sussex Plumbing LLC
Sussex Plumbing LLC
Over 30 years experience.
"Late on a Friday, we experienced a leaking water line behind the fridge- and the shutoff valve was broken. Sussex plumbing promised to come out, showed up on time, promptly fixed the leak and did a quick repair on the shutoff valve. They planned to come out the day before we were to get a new refrigerator to replace the faulty valve and did not charge for this urgent repair at that time. Instead Sam told us Cindy would give us a quote the following Monday that would include the urgent repair and the work required for the replacement valve. Sam showed up on time, did a fantastic job, and was very professional. The price for both jobs was extremely reasonable. We will never use a different plumber for any plumbing job we need done. Thank you for the great work!"

"We had water in our crawlspace after heavy rain. We hired Adam Basement to remedy the problem after consulting with three companies. We hired Adam Basement because of their excellent reputation in our neighborhood and because Bob of Adam Basement is a superb communicator, who explained the problem and proposed solution to us in a logical and easy-to-understand manner. Adam Basement installed a pressure relief sub-floor drainage system with a drainpipe and two sump pumps. They treated the crawlspace for mold and mildew and wrapped the floor and walls with a vapor barrier. Adam Basement’s technicians were hard-working, technically proficient, and professional, and their office staff were responsive and helpful. We’ve had the system for six months and are very pleased. The crawlspace has remained bone dry after heavy rain, and it looks and smells great. Adam Basement stands behind its work, as it provides a 10-year sump pump warranty and a lifetime, transferable waterproofing system warranty. We wholeheartedly recommend Adam Basement for basement repairs or waterproofing."
