"Alec from Aqua Sewer & Drain Service very professional when he showed up to check the water leak we had. Alec diagnosed the issue and said we needed an expansion tank since it cracked and that’s where all the water was leaking from. He said we don’t need a water heater because that is functioning properly. He took some pictures and then went to get the parts and came back within 30 mins and started the work. You can tell he really knew what he was doing. He had all the right tools in his work truck. He removed the old expansion tank and put in the new expansion tank and a shut off valve and he also strapped the expansion tank so it got added support. He also check the water pressure and looked for leaks before he left. We had this issue Friday night around 11pm and we call his company Saturday morning and he should up at 8am. It took about 2 hours before he finished. Alec was very knowledgeable, he also wore booties on his shoes in our house. I would recommend Aqua Sewer & Drain Services to anyone who has any plumbing issues. We live in South Brunswick NJ."

"received an estimate much lower than Horizon Services for same brand of water heater.  Installed the heater, expanded and redirected the vent pipe.  Good service, very polite, responsive and tidy.  I have used them before to install a sink.  I would use then again.

"Excellent customer service. My Hot water heater busted on Christmas night and i called advanced professional 26th early morning, tech at my home in no time to provide estimate and work was done within next 4-6 hours. Technician name Abe who came to my house for service is one of the best. Very polite, professional and make sure work is done neat and clean. Only one thing i am not happy is i think it was little pricey but since it was urgent service i can't complain."

"Keith came out the same day I called and identified the water leak under our hot water heater. He and his son came out three days later and jackhammered the slab and replaced the broken pipe. They then refilled the hole and laid new cement and replaced the hot water heater. Keith then took the extra trouble to re-route and replace the water supply lines to meet code. Now we have hot water and NO LEAK! Other than a slight change of concrete color you can't tell the repair was ever done. We are extremely pleased with the team Keith and his son and highly recommend Blue Boxer Plumbing!"

In 1993, Tom Raynor began taking on electrical construction and service jobs across southern New Jersey. With just one assistant and one beat-up truck, Tom crisscrossed the state, building a reputation for his small outfit as one that offered professional, hands-on service and reliable, high-quality results. By 1994, it was official—Raynor Services was born! \n \nSince then, that red pick-up has been upgraded to a fleet of ten fully stocked trucks. We are now a “one-stop shop” service company, specializing in electric, heating, cooling, and generator services. Raynor Services has never lost the spirit of professional, hands-on service that it was founded on. Family-owned and operated, we combine small-business service with big-business expertise. \n \nRaynor technicians are among the best in the industry. Each must complete a rigorous hiring process – including a background check, a drug test, and an HVAC or electrical proficiency examination.
