"Tim was fantastic. We live out of state and we felt so comfortable and confident that he and his staff could handle the whole house renovations. Tim went above and beyond his role of contractor. He understood the issues that we needed to get the house in shape and quickly to get it sold. We would not hesitate to hire him again."

"They did an excellent job. Put a threshold drain in front of a sliding door to my patio. They had to remove pavers, install a 4 inch pipe across the lawn and replace the pavers and sod. Hard workers did a really good job."

"We are very please with our new bathroom, it's a perfect addition to the master bedroom. During the demo and constrution phases a dummy wall was built to seperate the work space from the rest of bedroom, that allowed us to still sleep in the room. The craftmenship was excellent, and the work was done on time."

"We started out looking for an architect/designer, and met the owner of Tseranos Construction, Sterg, in the process. He referred us to a design architect, which we used, and we ended up then hiring Tseranos Construction as our general contractor. Sterg was really great to work with. He found ways to keep costs down while doing everything that we wanted to have done. In the end, the garage construction project took about 5 months, but we are thrilled with the results. Would hire Sterg again for future projects."

House Leveling FAQs, answered by experts

Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it’s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The exact time can vary depending on the size of the project. Because the slurry mixture contains cement, it must fully harden to ensure that added weight from walking, furniture, or vehicles won't shift the concrete slab. A professional contractor can advise you on when the surface is safe to use. For comparison, if you use polyjacking instead, the polyurethane foam can dry in just a few minutes, but it's best to wait about an hour before use.

Concrete leveling can last anywhere from five to 10 years or more, and in some cases, it can be a permanent solution. The longevity depends on the method used and whether the underlying cause of the sinking is addressed. For example, mudjacking typically lasts five to 10 years, while polyjacking can last for 20 years or more. It's best to consult a professional for an accurate timeline based on your specific situation and any factors that could cause the issue to recur.

On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.

Costs range from $500 to $1,500, depending on the size and condition of the area.
