"Jeff, Rob and his crew were exceptional They answered all of my questions even took the time to show me how things worked. They installed a water catch basin and sump pump to replace our smaller 25 year old equipment. Jeff suggested a better pump They were meticulous in their work and cleanup except for the new pump you would not even know they're there. I would recommend ONCE&DONE for any of your waterproofing needs Thank you ONCE&DONE"

"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."

"Dave at DM Solutions was great! A flooded basement knocked out my boiler. With sub-freezing temps on the way, I was anxious about getting heat back on in the house as quickly as possible. Dave got back to me right away--much faster than any of the of the other Home Advisor-recommended contractors--and he was onsite within 2 hours of communicating with me. He quickly diagnosed the problems with the boiler, helped me get the house prepare the house for a period of cold weather while I worked with my insurance company, then when my ins company gave the go ahead, he fixed everything post haste. Excellent experience."

"I was really impressed, the work was completed in just one day! The crew was super great, they had a bunch of people out. They did everything too I didnâ  t need to get really anything set up. We just made sure the walls were clear of anything so they had room. I needed 148 feet of drain installed and ordered 2 new sump pumps with it. It came out to $13k (I found a coupon too!) and Iâ  m just really glad to get this taken care of. My basement usually floods with heavy rain, legitimately half way full of water and we just had a rain (semi heavy) and itâ  s dry. This is the first time Iâ  m actually excited to see it rain next to check out the basement lol. I went into it expecting this to just help mitigate the flood waters but Iâ  m really hopeful this install will actually deliver 99% dryness ð   ð   . I do have to say, I wasnâ  t sure Iâ  d choose DryTech at first because I must have gotten 3-4 phone calls a day from their calling team after looking into waterproofing on HomeAdvisor. They were reallly trying to get me to schedule with them but I wasnâ  t ready just yet. It was a tad bit annoying but after looking at the reviews and whatnot I was definitely onboard and so glad I went through with them."

"The installation went very well. The installation team, Rabi, Moe, and Murad, did an excellent job. They were hard working, courteous, respectful of us and our property. They explained the steps for the work carefully and involved us in decision making for several steps of the process. They cleaned up after themselves each day. They were with us for four days and each day they provided the same level of service. Our case manager, Rachael, kept us informed each step of the way. She answered questions quickly. Good experience. I would hire them again."

"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 FAQs, answered by experts

Sewer ejector pumps need to be cleaned at least once a year by a professional. You shouldn’t attempt to clean it yourself because it can release sewer gasses that are toxic to humans and can be fatal. But to keep the system as clean as possible between professional inspection and cleaning services, be sure to only flush human waste and toilet paper. Avoid flushing items that can clog the system, like paper towels, grease, oil, or menstruation products.

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.

Submersible and pedestal sump pumps are two popular types of sump pumps. Submersible models are covered by water in a sump pit, which helps keep the motor cooler and quieter. Pedestal sump pumps stick out of the sump pit, so the motor stays dry and is easier to access. Submersible sump pumps are the pricier option, but they also have longer life spans.

Costs depend on pump type, labor rates, and the extent of repairs or installation needs.

Installing a battery backup for your sump pump is recommended, particularly if you live in an area with frequent power outages or severe rainstorms. A sump pump requires electricity to function, and a battery backup ensures it can continue to move water out of your home if the power goes out, providing crucial protection against flooding. Additionally, frequent power outages can create electrical surges that might damage the sump pump's motor. A battery backup system offers an additional layer of protection, ensuring your basement stays dry.
