Job Stories From Cromwell, CT
Smart Jacks in Cromwell, CT

This Cromwell, CT basement had sagging beams that was causing a great concern to the homeowner. The homeowner wanted the foundation of his home to be strong, stable and level. After seeing an ad on television, he decided to trust Connecticut Basement Systems who are the experts in all things basementy! 

On the day of the appointment, Sales Representative Matt Kraus arrived at the home to inspect the problem. He instantly noticed the sagging beams and knew that we were able to help. He explained that this is a common problem where beams are often undersized and wooden posts can rot, shift and settle. Luckily, our Smart Jack System would be able to provide a solution. Matt explained that Smart Jacks can support loads of more than 60,000 lbs. which will correct the sagging beam. This is exactly what the homeowner wanted and decided to move forward with the project.

On the day of production, Foreman Victor Alves and his team installed the Smart Jacks efficiently and professionally. The job only took one day and the results were what to be expected: a more stable foundation! The homeowner was pleased with the work and was happy he trusted the experts at Connecticut Basement Systems.    

Business Foundation Transformation in Cromwell, CT

This Cromwell business was in a building that was built in 1928, and the foundation was beginning to crack. They called on Connecticut Basement Systems to help them repair this problem, and we were happy to come out, and offer them a full-proof solution!

We quickly decided that our Push Pier system was the best way to give the foundation solid soil to support the weight of the structure. Push piers are made with heavy duty steel and connected to the foundation by a steel foundation bracket. Best of all? They can be installed inside or outside of the foundation, and work year round! This company can now rest assured in having a foundation that is safe and sturdy for their business for years to come! Give us a call today for your FREE push pier installation quote!

We currently have a sump pump in the basement, but no back up (other than our generator) if we lose power. Would like an estimate on installing a back up pump should the main one fail and a battery back up if power is lost. I'm guessing our existing pump well would have to be enlarged to accommodate this.
