"Aaron Lenker add Corbin Gillichbauer of Groundworks leveled concrete walks around my corner lot in Montoursville Pa. They arrived around noon time and were finished about 5 1/2 hours later. They did their work very professionally. They did an excellent job. I would rate their work 5 of 5 stars."

"Honestly, I have never had such a positive experience with a contractor. they showed up on time, were friendly, polite, courteous, clean and efficient. In a single day they installed the entire system and left the place clean (within reason). This included jack hammering more than 30 feet of concrete floor and complete water ejection. Unbelievable. They will never be the cheap solution, but they are worth it!"

"At times there were some communication issues, but overall Wilson did a good job and was attentive/repsonsive whenever an issue was raised and brought to his attention. I cannot say that we would hire again..ONLY because this a Board decision and I am not a voting member of the Board. (I answered yes, as this is the only way to submit the review)"

FAQs for concrete foundation raise projects in Thornwood, NY

On average, it takes two to seven days to physically raise your house. However, this does not include the preparation work, which is often the most lengthy process. The entire project, including preparation, obtaining permits, disconnecting utilities, and any subsequent landscaping, can take four to eight weeks. This timeline ensures everything is done safely and that your home remains structurally sound.

If proper safety protocols are not followed, raising a house can cause severe damage, as the process involves applying controlled force to the home's structure. The risks involved make it crucial to hire a skilled contractor who uses engineered methods to secure your home and prevent any harm to your household.

If your foundation shows signs of instability after raising your home, you might need to add structural support. A structural engineer can assess your foundation and recommend reinforcements to ensure your house stays stable and safe for the long term. Available support options include installing additional piers or pilings, reinforcing existing footings, or using steel beams to distribute the load more evenly.

You will need a structural engineer to assess your home before you begin. These professionals determine whether your house is suitable for lifting and identify any issues that could compromise its stability. Their expertise ensures that the project is designed correctly and all risks are managed to achieve a successful lift.
