"Only company that returned call during hurricane and sent quote within days. Scheduled sump pump installation and crew was the most professional workers I have seen in a long time. They took care not to make a mess and made sure everything was clean before they left. New sump pump installation looks like it was always there. I would recommend them every day of the week if you need sump pump work."

"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."

"Excellent communication from the office. Steven came at the time that I was told and completed a sump pump replacement. He was patient and communicated with me very well. I have been looking for a new plumber so Good Tidings maybe the one. In terms of price, I don't know how much this would have cost but honestly I have too much in my furnished basement to be concerned when a huge storm is coming. I will be back to install a new backup pump from Good Tidings!"

Sump Pump Installation questions, answered by experts

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.

Sump pump repairs are typically handled by plumbers or waterproofing specialists who are experienced in handling basement and foundation-related issues. Plumbers can address issues like clogs, electrical problems, and mechanical failures, and waterproofing professionals may be ideal if the sump pump is part of a larger drainage or waterproofing system. 

Some people may also call on a general handyperson for minor sump pump repairs. However, for complex problems, hiring a certified plumber or waterproofing expert ensures the work is done correctly and prevents further issues.

Sump pumps remove excess water from the lowest point of your home, which prevents flooding. When a sump pit fills with water, a sump pump pushes that water outside of the basin and into an exterior discharge pipe. From there, the water flows away from your home, so it doesn’t damage your foundation.

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.

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.
