"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."

"Again! I call on Perez Asphalt and paving. And again they did a great job! They also did my driveway. Prompt, Efficient, they were neat. They were focused on the task at hand. They showed up they did the job with patients, cleaned up and left. The best part was the fair price, someone else tried to charge me more than double for the same job. Good experience throughout!"

"We hired Budget Dry to review our basement problems and hired them to do the waterproofing project, install new basement windows, install the Santa Fe dehumidifier, and recently they installed our back-up battery system. We highly recommend them -always courteous, get the jobs done quickly and neatly, and always respond when we need their advice/want to purchase new filters. A great company!"

"it was great, Kris and his team were great to work with, they came in and got the job done quickly and professionally, they cleaned up every day before they left. If it wasn't for his team our basement would've flooded multiple times a year. We feel like we got our basement back, doubling the size of our living space in the house"

Foundation Drain 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.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

Yes, many contractors offer warranties for their work. Confirm terms before starting the project.

A sump pump battery backup can typically run for 6 to 24 hours. The factors that affect its runtime include the battery capacity and pump usage. 

When purchasing your backup system, take these factors into consideration to determine which system is best for your home. If you live in an area with frequent and long-lasting power outages, consider a longer-lasting backup battery.

Yes, many modern water pumps are designed with energy efficiency in mind. Look for pumps with high efficiency ratings or those with an Energy Star certification. These pumps consume less power and can reduce your utility bills. Additionally, variable-speed pumps are more efficient since they can adjust the flow based on demand, providing significant savings over time.
