"I had a great experience with this company installing my new boiler. Their pricing was fair compared to other estimates I received. Dave walked me through the entire process and answered all my questions, and his team came in and did a great job with the installation. With so many scammers out there, I truly felt comfortable working with this company and will absolutely use them again in the future."

"Joe had done work for me in the past; He worked on my heating furnace during the winter; he installed a hot water boiler in my two family house one year ago; Recently, my other twelve year old hot water boiler was leaking. I called Joe this morning and he came within the hour and we agreed on a fair price for installation; then he came back this afternoon with the new hot water boiler to install. When it comes to expert quality work and affordable pricing, Joe at AAA HVAC is the guy to call."

"They were great to work with and came in with a competitive price. They were clean and efficient. Had 125 feet of French drains installed through our basement with 2 sump pumps done in one day. Came back a few days later to complete what was needed outside the house."

"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 been dealing with issues with my utility sink pump for over three months and had tried other services, but no one seemed to have the solution. I finally called ProsWay Plumbing, and Iâ m so glad I did! They were able to come out on the same day and resolve the problem completely. Their team quickly identified the underlying issue with my utility sink pump, explained the repair process in detail, and fixed it that very day. The plumber was professional, highly skilled, and respectful of my time and space. I was impressed not only with their technical expertise but also with how fast and efficiently they handled everything. I had almost given up on finding a reliable plumbing service in Randolph that could truly fix this ongoing utility sink problem. ProsWay Plumbing exceeded my expectations in every way and finally gave me peace of mind. If you're in Randolph and need sink repair services whether it's a kitchen sink, utility sink, or any type of sink plumbing. I canâ t recommend ProsWay Plumbing enough. Their same day service, professionalism, and commitment to solving problems make them the best choice for sink repair services in the area!"

"He came out same night after I called to assess the burst pipe from the lake. Next day he arrived early, brought the necessary materials, and got straight to work. Fixed the problem correctly and quoted a fixed price upfront. When he identified a better long-term solution, he explained the options clearly, laid out the actual costs for each, and let me decide without pressure. He delivered what he said he would, when he said he would, at the price he quoted. That's the standard but apparently rare enough to note."

Sump Pump Installation FAQs, answered by experts

There are several indicators that your washing machine’s drain pump is bad, including incomplete cycles, water not draining, lack of spinning, a foul odor when the machine is running, and a loud grinding or buzzing noise when the pump is trying to move water down the drain.

Costs range from $300 to $1,200, depending on the pump type, issue, and installation complexity.

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

The cost to repair a sump pump ranges from $400 to $550, depending on the extent of the repair and your location. Minor repairs, like fixing a switch or replacing a float, can cost just a few hundred dollars. However, more significant issues, such as motor replacement or addressing electrical problems, may cost closer to $550. Keep in mind that regular maintenance can help prevent costly repairs, and if a sump pump is beyond repair, a full system replacement ranges between $650 and $1,400.

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor.
