"Connecticut Basement Systems prides themselves on their superior customer service, and they really live up to that. Their communication, quality of products and service, and attentiveness to customer needs is unsurpassed. Here are a couple of examples of how they go the extra mile for a satisfied customer: They installed their basement drainage system around my existing heating oil tank, but as I'm planning to convert away from oil this summer, they offered to come back AT NO EXTRA CHARGE once the tank is removed, to reroute the drainage system. Also, I was scheduled for a 3-day project, which included the replacement of some flooring in my basement. On the day the project began, we reconsidered the need for the flooring, and asked if we could cancel that portion of the job. They could not have been more accommodating to that adjustment, and made the change with no questions asked or negative attitude, even though it significantly lowered the price of the project and eliminated a whole day of scheduled work on 2-days' notice. That sort of total customer dedication is rare. I recommend them highly."

"Excellent work.  Was refreshing to work with a contractor who did the simple things such as showing up when they said they would, completing work as specified, completing in a timely fashion and communicating all along.  AJ was great to work with and originally came out for drainage work and tying our sump pump discharge into buried PVC pipe to drain in the backyard away from the house.  We were also in process of running a gas line to the house and when asked if they'd be interested in excavating the trench, which was no small task at ~450 ft along driveway and several trees/stumps/rocks, AJ was more than willing to take on the job.  AJ coordinated with the gas company and dug the trench per their specifications and backfilled with sand all within a couple of days.
Once the gas line was installed, AJ and his team completed the drainage work which consisted of tying in sump pump discharge, three gutter downspouts and a yard drainage box to pick up excess surface water at a low spot near driveway.  The discharge was run approximately 100 ft to the rear of our yard and a pop up emitter was installed to keep all water away from the house.  All excavation was backfilled and top soil added and graded with seed and straw laid.  Grass seed began coming up within a week and has filled in nicely.  
Throughout the process AJ kept in contact with what was going on and what they would be doing next.  The work was completed faster than we anticipated and the crew kept the site clean each day when they were done.  AJ went out of his way to make sure we were happy with the work and made sure the job was completed to satisfaction including following up with me to make sure we were happy after the job was complete and he had already been paid.  The crew was great, worked hard and put in a full work day and then some everyday.  The were several challenges with this job including a tight work space with many trees, roots and rocks.  The crew took great care to make minimal disturbance to surrounding trees, shrubs, etc.  We were very happy with AJ and crew and would happily use them in the future especially considering the reasonable price.  We even had the neighbors comment on the quality of the work done and how fast the work was completed.

"It is very convenient, and reasonably priced.  The only thing that they could work on is the punctuality of the pick up times.  The rest of the experience was satisfactory.  My daughter has also used them.  I would highly recommend this service."

Sump Pump Installation questions, answered by experts

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.

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.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.

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.
