"It was installation of a sump pump. Craig, Tyler and a third gentleman whose name I canâ t remember were great. Arrived on time, did a wonderful job, were professional and answered all my questions. I highly recommend them. Took only a day and a half from start to finish."

"Called in claim on 6/18; tech assigned on 6 /19; so far so good. Claim was for failed well pump with NO water to my home with two disabled seniors. Due to heavy workload and no extra pay on weekends the tech came for diagnostics 4 days later. He verified the failed pump and tried to purchase one at Home Depot. None in stock, had to be ordered. Pump came in on 6/30 and tech arrived today, 7/1, and expertly installed the new pump. Choice has a $ 500 limit on well repair, which is 1/3 of a typical bill. That dollar cap is riduculous. On a positive note, C-Force provides expert work for Choice and would be my choice for any future work."

"Goettl & Verbracken did a very competent job for us under difficult conditions in an older home. Working side by side was helpful for both parties, as questions always come up. Location of installed flex gas line (next to and in the same opening as the metal dryer vent) was not anticipated. I drilled a new hold with spade bit and extension and rerouted the gas line. Otherwise, we are happy with the work done and would hire again!"

Sump Pump Installation questions, answered by experts

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.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

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.

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

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.
