"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!"

"Where do I start?! Let me just say, from beginning to end, it was 100% professional. These guys came on time, they did their job, they cleaned up, very professional, straightforward, hard-working, and much much more! They installed a water heater with no issues. The old water heater was picked up. I recommend them to do any HVAC for you! I will be calling them to install an air conditioner unit in the Spring. They were so kind, quiet and just did their job. I am so happy that I chose them amongst other HVAC quotes. Call them today! You will not be disappointed! Thank you guys for a job well done!! Now I can sleep at night, knowing my water heater will be working correctly!"

"The men arrived on time. The original assessment was that the interior wall would have to be cut open and wainscoting removed then replaced in order to access the pipes. However they first tried to remove the faucet from the outside wall and were able to do so. The faucet was replaced at minimal cost and in a short period of time. They were very polite and left no mess. I have used Eddie B for several years and will continue to use them in the future. Thanks Eddie B."

"We had two plumbers out to our house who weren't even willing to get in and diagnose the problem in our crawl space. We ended up with a $9k quote to reroute and replace our water line (not even the entire line) even though they did no tests to confirm an issue. We called Chris, who was very accommodating and came out quickly. He actually listened to us and explained options in terms we could understand. He and his team clearly know what they are doing and are honest people. Lucky for us, Chris didn't jump right to a quote to do the biggest job. He gave us some advice on trying to locate the leak to avoid completely replacing the water line (though we were completely comfortable having Roesly on board if we did need this!). He was spot on! We found it and it turned out to be an uncapped old plumbing line! Dan at Roesly came out within 30 minutes and had no issues getting into our crawl space and fixing it the right way! Had we gone with the $9k quote, we would have turned the water back on only to still have leaking water! Roesly's team are hard honest workers and overall great people! We won't use anyone else for our plumbing needs!"

FAQs for water main install, replace or repair projects in Williamstown, NJ

If you notice puddles or standing water in your yard, a sudden drop in water pressure, cracks forming in your foundation, frequent clogs in your plumbing fixtures, or water that looks or smells unusual, you might have a leak in your main water line. These signs mean it's time to call a professional to evaluate the issue and prevent further damage.

A professional water main inspection is a comprehensive evaluation performed by a licensed plumber who checks every section of your plumbing system. The inspection costs $165 and uses advanced diagnostic techniques to identify hidden leaks or wear. This service clarifies the exact condition of your water main, enabling precise repairs that prevent future damage and ensure the overall health of your plumbing system.

Protect your water main by scheduling a cleaning and inspection every two to five years. The average cost of a sewer line cleaning is $400. It’s also important to never dig in your yard without first calling the dig line (811) to ensure you don't accidentally hit the water or sewer lines. Watch for soil erosion, low water pressure, or wet spots in your yard, and take immediate action if you suspect a leak. Remember, the longer you leave it, the worse the problem gets and the more costly it is to fix.

When properly maintained, your water main is engineered to remain functional for 50 years or longer. A durable water service in excellent condition should consistently perform without major issues for half a century. In contrast, metal pipes exposed to acidic soil corrode faster, whereas modern plastic pipes resist corrosion and function for decades beyond metal alternatives. Regular maintenance and inspections are essential for confirming your system’s longevity.

No, homeowners insurance does not cover the cost to repair a water main. Insurers fund only sudden, unforeseen events like a burst pipe and exclude gradual issues or normal wear and tear. Damage resulting from leaks, such as mold remediation or property claims, is not covered. It is essential to contact your insurance provider immediately to confirm your policy’s details and any potential adjustments needed.
