"Moose and the team at Complete Heating and Cooling / Complete Construction were excellent to work with. 3 business days after signing the contract equipment is on-site and installing the header units. A day or two after that (mainly due to weather) the condenser was installed. The HVAC had to be charged and with any other contractor a homeowner would be thinking "when is he coming back?" - I didn't have to chase them down they came to me and within a day they setup a time to come and charge the units up ensure there were no leaks. Very professional and I look forward to future projects as they cover a vast array of construction areas."

"Called after 530pm on Saturday night. Received call back in 5 minutes with attempt to trouble shoot. In did not fix the problem and technician was dispatch and arrived within 20 minutes. Greg upon arrived identified himself and immediately started servicing furnace. Diagnosed that furnace fan limit control switch was not functioning and needed to be replaced. I noted that he tested the switch 3 times before confirming. Being a part not on truck, Greg apologized for not being able to fix the furnace tonight. He ordered the part ,advising parts warehouse closed until Monday morning. He advised me to call office after 10AM Monday if I don’t hear from main office. Greg was professional and courteous throughout the service call explaining everything he performed. Arctic Air came highly recommend and I am looking forward to them complete the repair in coming days and I will be scheduling yearly tune up for my 2 air conditioning units this spring and all my furnace needs in the future"

"Ramon from Gold Medal ran new 20 amp circuits and replaced 2 hardwired sconces. He was very professional, checked in with me every step of the way, walked me through everything he did, and stayed within my budget. I would definitely hire them again. The only thing that was less than ideal happened when I called the office. Maybe I called at a bad time, but I was on hold more than once for a very long time, so it took a total of 10 minutes to reach someone to answer one question."

"Rob and Jean came in as scheduled. They were professional and courteous. We had to snake out the main sewer line. They cleared the blockage. Rob also recommended DIY items that could improve overall condition of the basement. Overall, Rob was pleasant to work with. Even when my nanny accidentally flushed while drain was open!

"Louâ s plumbing is the best! I know that plumbers are suspect most of the time. I donâ t know if it is totally deserved or not, but Iâ m a car salesman so I know what itâ s like to have people think youâ re going to take them. I called Lou on Sunday and my call was returned the same day even though it wasnâ t an emergency. The first day I could be home was Tuesday and the boys were at my house Tuesday morning as promised. My problem was one of the pipes going into my water heater was severely corroded, if it blew there would be quite a mess. When the heater was installed, it wasnâ t done properly. If it couldnâ t be corrected, it would mean a new water heater probably costing around $1400 before installation. Lou explained that it was going to be a challenge to replace the pipe but they would do their best. They had to leave to get some parts but were back in ten minutes. Ten minutes after that, the job was done and no new water heater was needed. What a relief! The price was terrific! Thereâ s another job I need done in the spring and you can bet Iâ ll be calling Louâ s Plumbing. Reliable, trustworthy, polite and affordable. What more can be said? Use Louâ s plumbing!"

FAQs for sewer main install, replace or repair projects in Flemington, NJ

Most trenchless sewer line replacements can be completed within one to three days, though this varies based on your situation. Simple repairs on accessible lines might be finished in hours, while complex systems or challenging soil conditions could extend the timeline. The reduced excavation requirements result in faster completion compared to traditional trenching methods.

Trenchless pipe lining may reduce the interior diameter of your pipes, which could affect flow capacity in already narrow lines. This method also requires the existing pipe to maintain sufficient structural integrity to support the new liner. Severely collapsed sections, major joint separations, or completely misaligned pipes might not be suitable candidates for lining and could require alternative approaches.

Trenchless sewer pipe liners are rated to last up to 50 years when properly installed and maintained. Actual longevity depends on installation quality, usage patterns, and environmental factors like soil movement or tree root intrusion. Regular maintenance and avoiding problematic disposal practices (like flushing non-biodegradable items) can help maximize your system's operational lifespan.

Trenchless technology availability varies by region, with greater accessibility in metropolitan and suburban areas where specialized contractors operate. Some rural locations may have limited access to trenchless equipment and expertise. Local regulations and soil conditions also influence availability. A professional assessment of your property and local contractor options will determine if trenchless methods are feasible for your specific location.

Professional video inspection provides the most reliable assessment of whether your sewer issues suit trenchless repair. Generally, pipes with moderate damage, like small cracks, minor leaks, or partial blockages, respond well to trenchless techniques. Completely collapsed sections, severe misalignments, or extensive structural failures might require traditional excavation. Consulting with contractors who offer both methods ensures you receive unbiased recommendations.

Quality trenchless sewer replacement often includes a workmanship guarantee from the contractor. The specific terms vary by company and region, but many professionals stand behind their installation for at least one year. Material warranties may extend longer, depending on the pipe products used. Always request written warranty information before hiring, and understand exactly what's covered and what might void your protection.
