"It was excellent - because the serviceman was in my area, he came over almost immediately, diagnosed the situation, and offered several solutions. I opted for a new faucet which he promptly offered to go purchase and install that afternoon. I was thrilled that within a matter of hours the problems was diagnosed and corrected!!"

"They were the first to give us a quote and were able to come out as soon as we needed them to. Installation was smooth, and they have been good at following up to make sure the system is working. Because our radon is still slightly high, they are doing another radon test and will follow up if it comes back high yet again. We would definitely recommend them to others!"

"I appreciated Michael's professional and friendly manner. We needed two new parts. He installed only the necessary replacement parts to avoid the job costing more than necessary. Also, his explanation of what he was doing was important. He corrected and completed the work in a reasonable amount of time. Thank you, Micheal!"

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"We hired Todd for an extensive remodel of our home and couldn’t be more thrilled with how nice it turned out, how smooth the process was, and how helpful Todd was along the entire way. The project has been complete for a while, I am just now following up with a long overdue review. Downstairs Todd removed 2 walls including a staircase to create an open living space for us. Where the walls were removed, he installed 3 new support beams per the engineer’s design, and then wrapped them with rustic oak boards to make them look like original beams, and they turned out beautifully. He installed all new trim around the downstairs windows to match the rest of the house. Todd gutted our old kitchen and built an island for us, installing all new cabinets, crown molding, and the appliances. He even custom modified 2 drawers in the island so that we could conceal the electrical outlets behind part of the drawer panel but not lose the entire storage space of the drawer. He did such a great job with the drawer modification they look like they came that way from the factory. The entire kitchen turned out perfect. During the same remodel, we also hired Todd to combine 2 bedrooms into a new master suite. This involved removing walls, installing a beam, and installing new walls for the new master bathroom and closet. While the ceiling was opened up Todd noticed a drip coming from above on a rainy day, and after finding the source, he offered us a very reasonable price to replace a small section of siding to ensure we wouldn’t have any water issues. We are grateful he was so observant and willing to go the extra mile for us by fixing this issue that was not originally in our scope. In the new master bathroom the extensive amount of tile and the new glass shower enclosure that he installed couldn’t have turned out any nicer, all the lines were perfect. He took great care in his tile usage, minimizing waste with his cuts which we appreciated especially on the expensive tile he installed in a decorative strip. Todd was great to work with throughout the entire project and very professional day in and day out. Being such a large project, as it progressed there were several things we realized we wanted to add to the workscope while everything was opened up. Todd was very accommodating and gave us reasonable prices for each addition we threw his way. We appreciated his flexibility very much. Todd also helped us with various design considerations, and had some great ideas that helped us work with the engineer to get the upstairs beams laid out in a way that optimized our new space. He pays close attention to detail and worked hard to ensure we would be happy with the end result of the project. Overall Todd is a real pleasure to work with and we highly recommend him and the quality of his work."

Sump Pump Installation FAQs, answered by experts

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

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

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, many providers offer warranties for new pumps and labor. Confirm terms before scheduling.
