"After dealing with roto rooter and Losch plumbing with very bad experiences. Thank God for finding Once & Done. Very professional crew, they did a great job in installing the new sump pump that we definitely needed. Jeff was very honest and nice and explained everything that had to be done in detail. Highly recommend."

"We had an older Heatmaker combination unit boiler that was 32 years old that needed to be replaced. We started out with several estimates and first decided what could be used in our space constrained garage. We decided on a Navien combination unit and focused a obtained a couple more estimates. Dawson in fact was one of the last estimates we obtained. While Dave from Dawson had the benefit of us being well along the learning curve, he was able to answer all of our questions about the new unit and how best to solve the condensate dilemma. He even was spot on with regards to treating our well water to minimize scale buildup in our new boiler. We knew we had reached that point where we felt we had found the best installer in Dave. Dave verified his condensate solution with the local township inspector and we scheduled the install date in two weeks. Carlos and Pablo showed up on time and dismantled the old unit and piping and did a first rate and well thought out installation job. Carlos had extensive experience installing these Navien units and it really showed. They managed to work in a tight space that PSE&G’s installers would not have with relocating a well tank. After all the plumbing was done, Ricky did the electrical work and adjusted some final dip switch settings before firing up the new boiler. Dave and his crew really are top notch. His front office staff (Wanda and Ondrea) made the PSE&G interest free financing and permitting approval process seemless. We are looking forward to the operation and efficiency of our new high efficiency boiler for years to come. If you are installing a Navien high efficiency combo unit, we highly recommend using Dawson Mechanical!"

"Hi, I am an old customer of Select Basement for many years. This is my incredibly happy and satisfied review on the service call by Kenny M. First the backstory. The alarm went off on my battery backup on Wednesday early evening I called Select several times and no one got back to me. I just wanted to know if this was a serious problem. Considering all the rain we were having that week. This was unusual for Select not to return my call in a timely manner from the great service I had received from Select Basement for many years. I explained to the customer service representatives who took my calls who were very professional and tried to help but to no avail no one called me to answer my question. I received a called back Friday morning to set up an appointment for Monday to look at the alarm on the battery backup to the sump pump. I inquired if our annual maintenance check could be performed at the same time and was told yes. Monday morning Kenny called to say “He was on his way”. My appointment was at 8, he arrived 7:45. This was great because I had a 9:00 virtual business meeting. I explained my frustration with Select Basement and merging with Groundworks. Kenny took the time to explain the system changes and how things work now with Groundworks. Kenny proceeded to look at the battery and said it is working properly now. He asked how long we have had it. I said several years he recommend changing the battery, which he did. Kenny also performed the maintenance of flushing the French drain system to make sure that is still working fine. He took several pictures along the way to validate what he was doing. He addressed the dehumidifier that we have, he adjusted it so it would drain into the nearest little french drain hole. Kenny did a great job. He was careful to address all the issues that he thought needed to be addressed. Kenny was very professional and respectful technician leaving no mess behind. Our water has a lot of iron ore, Kenny cleaned the ore around the pump and also offered a recommendation on how to reduce the ore around the pump. He also explained the difference in the service pricing for the warranty offered. I appreciated Kenny taking the time to explain everything that Groundworks now offers to their customers. I know Select Basement and Groundworks merged only a few months back. However, the most important thing is customer service. If I called on Wednesday night thinking I am having an emergency, I should not have to wait for my call to be returned on Friday morning. I text Jason from Select Basement late that evening since no one got back to me right away . Jason responded right away and put my fears to rest and suggested a few options for the alarm shut off that did not work. He said he would pass the issue to the one of the managers. There has to be better response to customer when several calls are made with not even a touch point call back. Thank God by basement was not flooded. Select would have lost a customer."

"I had their technician (Julian) hook up & tested my pool pump, also fix a clogged toilet. Julian was very thorough and explained everything that needed to be done through the entire job. Couldn’t be more happier with their service, I do find their price is on the high side, however I would definitely recommend & hire them again as not all plumbers or even pool company would come & hook up existing pump"

"We have worked with Quality First Basement for 20 years. First job was the triple sump pump which has been excellent. Next was the refinishing of our basement. Another superb product and experience. Today we had new flooring installed. Once again, the product and workers were excellent! They were on time and so respectful. The floor is so attractive. This is a company that has only gotten better over the years! I highly recommend it! Rachel Padian"

Sump Pump Installation questions, answered by experts

One common reason a sump pump stops working is improper sizing. Different locations need different sizes and power ratings of sump pumps depending on the typical amount of water the pump needs to manage. If your sump pump is too small for the quantity of water, it can overwork and either burn out or reduce the life of the unit. If the pump is too big, it can overwork and burn out early. 

If your sump pump isn’t engaging, it might be clogged with dirt and debris. Check to see if the fitting lid is loose and has been letting debris in. Next, check the float and make sure it’s not obstructed by rust or gunk, which results from insufficient maintenance. Tangled wires or damaged switching systems can also stop your sump pump from engaging.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.
