"I placed an Angi service request and choose the first responder. I needed to replace the sewage ejector sump pump, and during the total basement plumbing inspection, a leak was discovered on the main line of the hot water boiler, with evidence of water around the base of the tank of the boiler area. After a discussion with the technician, I eventually decided to replace both items."

"I had a wall in my basement that was filing up with water from runoff outside. The wall started leaking into my basement. The crew jackhammered a trench along the wall in my basement and installed a drainage pipe, fill and a sump pump. They cemented over the trench and it looks like they were never here. Lots of rain since then and my basement is dry. Timely and professional- highly recommend"

"We had numerous issues with water in our basement in the 5 years we owned our home, it was not an easy fix and we received numerous ideas and quotes. The rep from Worthington came out and was amazing, did not try and up sell us, and identified and fixed every problem. Worthington was not the cheapest firm we spoke with but would you really want the guy with the lowest price for a job like this? We would recommend this company emphatically."

Sump Pump Installation FAQs, answered by experts

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

If your water pump fails, the first step is to turn off the power to the pump to prevent any further damage. Check for common issues such as clogs, electrical problems, or mechanical failures. If you cannot identify the problem, contact a professional who specializes in pump repairs. Prompt action can help minimize damage and repair costs.

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.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

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