"Our service person was Bill Fanning. He was excellent and explained everything in full detail! Bill was polite and respectful, and advised us on the best new sump pump to replace our non-working sump pump."

"Plumber was punctual and completed work in professional manner.  In fact, he found a potential plumbing problem with gas dryer connection that could have caused additional problems.  I have used this company before and once again they lived up to their A rating.

"SILA is never going to be the cheapest but if you want something diagnosed swiftly and fixed or replaced just as quickly, you can't go wrong with these guys. They were the only ones to correctly diagnosis and fix our ailing furnace three years ago, so we trust them. For this problem, they tried to get the old pump into working order (turns out it was the kind that needed to be oiled; the contractor, not SILA, who installed it along with a heavy duty basement dehumidifier, never told us it needed oiling for routine maintenance). The SILA tech did all the diagnostics on the drain hose (no blockage there) and then tried oiling the motor. It was running but not well enough to push the water up the hose and down the drain. A new pump was the last alternative. Within 20 minutes, the SILA tech replaced the pump with one identical to our furnace condensate pump, which never needs oiling. Everything is working fine now! They also have good coupons/deals when you get on their email/mailing list."

"I posted an initial review on 2/21/19 on a job done on 1/11/19 to fix groundwater from coming into our basement. The drainage system and sump they installed was not collecting all the water that was coming in, as we had leaking from several areas along an uneven rock ledge. I had reached out to our salesperson by phone and email and never heard back, so I was very frustrated. About 3 weeks after I posted the review, I did get a call from Jeff Allen, one of the supervisors. To make a long story short, he sent out one of their waterproofing specialists to look at the problem. We had already hired an independent mason to try to remedy the problem but he had not yet had a chance to do the job. Jeff convinced me that CT Basement systems would do absolutely whatever it took to fix my water problem. I cancelled the independent mason. Danny, a mason from CT Basement Systems came out and used a very ingenious method to divert all the water to the originally installed water guard trough and then to the sump. It is working beautifully!! I think Danny is a genius and I am so impressed and thankful for Jeff's perseverance and kindness in making this happen. I am now a very happy customer."

"These guys were great! We got turned down by two large companies because our dryer vent was almost at the peak of our roof on the second floor, but these guys took it on. They came out the same day we spoke with them to take a look and draw up a quote and then came back the following day to do the cleaning on our dryer vent and put in a new vent on the house. The previous owners had on the wrong cover which caused most of our issues to begin with. I would recommend them to anyone we know. They were professional and explained out everything."

"They came out on a weekend and we're our saving grace during one of the most frustrating experiences we've had in this house. We couldn't use any plumbing without flooding the basement with sewage, it was early stay at home days, and we felt like we would go mad. They showed up and gave us an price for replacing the broken pipe, and set in to work. They worked for the entire weekend essentially, staying extremely late at night and showing up early the next morning, and at one point driving far out at night to get supplies since their usual local place was closed (again, quarantine time) . The reason it took so long was because after opening up the floor to get to the end of the pipe to replace it they found more damaged pipes, and replaced those as well. By the end of it they had spent the entire weekend on a job they expected to only last an afternoon, had charged us not nearly enough for the amount of work they did, and fixed a leaking bidet we had for free for good measure. They also advised us to do camera scan to look for any other problems, which they couldn't do until the water drained out, and even did an initial mop of the basement (which, remember, sewage flooding). I'm honestly half convinced these people are magic helpful brownies or something, it's unreal how helpful they were! Somehow our drier which has not succeeded in drying clothes for over a year has started working in a single cycle since they left, despite the fact they didn't even do anything with it, and in fact specifically said they don't do driers and offered to recommend someone else when we mentioned it. Suffice to say, I cannot recommend them highly enough"

"Extremely satisfied.  Company was responsive (My initial call to them was on Xmas Day when I noticed the sewer backed up in my back yard).  They called me back immediately and  agreed to send someone to look at it the next day (after ansering some questions, we agreed it was not an emergency) - they came the next day as promised and even called prior to their arrival.  The plumber assessed the situation and took pictures to send back to Larry.  I spoke with him and agreed to have them come back on Monday when the equipment  needed to address would be available (needed an extra long hose and camera set up given the location of the cleanout cup).  Each time dealt with the company (Larry) he would call to let me know status and options.  On the day they came, Larry and his associate were at my home at the time promised.  Spent nearly 3 hours and all is well.  So although a bit pricey, well worth it given the responsiveness and professionalism of the company.  Would highly recommend them for any of your plumbing needs.

Sump Pump Installation questions, answered by experts

Common problems include motor failure, clogged discharge lines, and float switch malfunctions. Regular maintenance prevents many issues.

DIY is possible for simple repairs. Professional services ensure proper diagnostics and long-term reliability.

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.

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 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.
