"I can’t say enough great things about Best Sewer and Drain. The owner personally responded to my call and was at my home within two hours — truly impressive responsiveness! What started as a simple clog turned out to be a much bigger issue, but they worked tirelessly until everything was completely resolved. The owner was not only professional and highly skilled but also genuinely kind and helpful. He went above and beyond, even cleaning up the area far more thoroughly than expected. It’s rare to see that level of dedication and care these days. If you’re looking for honest, dependable, and top-quality service, I highly recommend Best Sewer and Drain.

Jones Services is now a NO CONTACT service company. Our plumbers, electricians and HVAC technicians are running NO CONTACT service calls. We literally stand in different rooms than our customers, emailing or reading out loud our findings. No handshakes, no paperwork, not even allowing customers to touch iPads. Our technicians wear disinfected gloves, use disinfected tools and whip down anything their gloves and tools touch after servicing equipment. We practice NO CONTACT at work now too. Technicians are not allowed in the office, equipment and parts are delivered to their trucks in the parking lot. Only one employee per vehicle. All company meetings are conducted via Zoom. Most office personal are working from home. Those in the office work apart from each other. No one wants to be quarantined with their toilets backing up, without water or electricity or heat or hot water and now without air conditioning or air filtration or air purification. We are doing everything we can to help all our employees stay health to protect ourselves and our customers.

"Rick, the initial assessor for the (HVAC, electrical and plumbing work), was superb! He efficiently inspected the areas and subdivided the work while giving useful feedback. I look forward to the help from Jones Services!"

Welcome to Veterans Tile LLC, A veteran owned and family business. We do Tile installation, removal and repairs, from bathrooms, kitchens and floor remodeling!

"“Veterans Tile”, Sergio Jr, and his crew came highly recommended by our neighbor who had her own work done by them. We had a massive project in front of us, as our existing back patio and front porch (circa 1957) was a crumbling mess of concrete. We had multiple contractors come in for estimates, and most of them told us that the scope of work was too much for them to handle, and others came in with astronomical estimates. Being fairly new to the Hudson Valley, this made us uneasy on whether we would ever get this done? When Sergio Jr accompanied with his dad came, their demeanor was with complete confidence, respectful and with a smile. Every aspect was explained to us from start to finish. The work started, and finished in exactly 9 days, as we added more projects on like an additional walkway, as well as shoring up the footings on our rear deck. The crew did phenomenal and professional restoration. We look forward to working together again. Very satisfied!"

"We have a smaller upstairs bathroom that had not been touched since 1975. The shower had been unusable for over a decade due to leakage. The space had to be completely gutted down to the studs and completely redone. The contractor we had used several times over the years retired, so we needed someone new who we could trust. Radical Renovations (Angelo) was recommended to us by N & S Supply in Kingston and I'm SO happy we hired him! He's professional, responsive, patient and finds solutions to all issues that invariably come up when you're dealing with old homes. Plus, the crew who he brought in to work with him was also pleasant and professional. I would absolutely hire Angelo again...in fact I already am!"

Boiler Repair questions, answered by experts

HVAC maintenance is crucial for the longevity of your unit. Without proper care, your HVAC unit can break down frequently. In addition, a system that is dirty and not cleaned correctly will not heat or cool as efficiently and will increase your energy bills due to the increase in energy consumption. Additionally, you will probably have to replace your unit sooner than you would if it were properly maintained, which will cost you more money. 

It can be difficult to determine the cause of a coolant leak unless you have the unit inspected by a certified professional. Most coolant leaks are caused by wear and tear on seals and joints. This typically happens five years after a unit is installed. Additionally, faulty or worn compressors, evaporator coils, and condenser coils can also cause leaks.

There are a couple of signs that will tell you it’s time to bleed the radiator. If the radiator is making noises, it’s typically because of trapped air, which you can release by bleeding the radiator. You can also test the radiator by turning on your heat and then placing your hand near the top and bottom of the radiator. If you feel cold spots, particularly at the top of the radiator, it’s time to bleed it.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Annual servicing, checking for leaks, and maintaining proper pressure extend the system’s life.
