"well there were delays but i forgive that. they did NOT get permits. a new hot water heater was brought and hooked up. But connections were loose and made it inoperable! its taken another plumber and an Electrician to fix what was wrong to actually get hot water. the original cost was $2500. Now add the $500 for 2nd plumber to reinstall the emergency shut off box that was installed improperly. AND an Electrician for $800 To fix the rest. They have not responded to email requesting attention. Technician was great - altho did not know everything necessary to complete my job. this has been a two week nightmare! i am NOT happy!"

"We use Laury for repair and maintenance of our heating and cooling units for our rental properties and each time we need something done, the staff at Laury never cease to provide quality service. The technicians are always knowledgeable, thorough, courteous and pleasant. We recently had an HVAC system installed in one of our units and the home is rather large and is over 100 years old and there was not a whole lot of empty space to work with. The guys at Laury were able to install the system and all of the duct work and components involved neatly with the age and make-up of the home in-mind. They were pleasant throughout the entire installation which took almost a week. They were always on time and always communicated the process with us. Laury is a trusted business with many years of experience behind them. Prices are also extremely reasonable given the cost of services right now. Warren you are the man!"

"It was amazing 🤩 I made a call to MAS and Harold and Lauren were at my home the next day. Harold, Pete and Gabrielle were extremely hard working and so courteous and such a joy to work with!! I actually was so pleased with the deck that I asked for a quote on vinyl fencing. I would strongly recommend this company for any work needed. It means so much when the actual owner of the company comes and does the work alongside his employees. I did happen to see one horrible review from someone who was 100% 😑. It was actually the only bad review so clearly it was not the fault of MAS but rather the idiot that posted such an incredibly inaccurate and incorrect review. I will definitely recommend this company to my family and friends and take it from me, I can really be a PITA when things are getting done at my home but not once was I ever meant to feel like I was being a PITA. The customer service skills of Harold and Lauren and their team is remarkable!!!"

FAQs for water heater repair or service projects in Williamstown, NJ

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
