"Ron and his assistant arrived on time to do some fall cleanup landscaping at my house. What would have taken me three days to do, plus hauling away the debris, took them under two hours. It was the very best money I ever spent - more so because I got to meet such lovely people, but also because they helped me a great deal. I will be calling them in the spring for a clean up and masonry work."

"We moved into a lovely house with many unsuspected problems including a very wet basement back in Nov of 2017. I did much research to find the best outfit to fix the problem. Ct Basement was not the cheapest. In fact, they were the most expensive by far. But, they were also the yardstick every other company compared themselves to. The job cost us 19,300. And we had to wait weeks for the work to start. BUT, everything went perfectly. As soon as the old debris was removed, I was shocked to find that the garbage of the old walls and flooring they removed had black mold under it. And, with its removal, my wife’s athsma cleared up and left town! They did a beautiful job, were very polite and the new installed basement, new sump pump with back up battery, perimeter trench, flooring, etc., all is great. They put a lot of work and material in to do this job with very skilled workmen who worked very hard. Sometimes you get what you pay for."

"The gentleman who came to my home were absolutely great! Explained everything and made sure I was happy with the work every step of the way. I was nervous in the beginning but my fear subsided after Robert Charlesworth, Marcelo largo, Isaiah belcher and Johnathon Lopez made for a great experience. The attention to detail and dust control, tapping off areas they felt I wouldn’t want getting dusty exceeded my expectations! Thank you for your hard work and kindness. Trucks looked awesome new as well as tools and equipment. Great job guys!!"

"My mom loves greenery, so I decided to get some landscaping done outside her house. I called their professionals to inspect the area and suggest designs accordingly. Their team gave me such beautiful ideas entirely within my budget. My mom got super happy to see the entire landscaping done. It has become her favorite part of the house. I do not have the right words to thank you guys enough and suggest them to all."

"The contracted the work off to a third party. Jon took longer than expected. The windows was installed pretty good from the looks. Communication could have been better with knowing the job will take longer and what types of trims I wanted for the windows. As the contractor that was hired for this job by this company. Did a good job with putting up decent trim. As for the new windows they look great. I purchased the myself and hired sentri homes to install them. I will need to have a my siding on my house redone to be closer to the new windows so the gaps are not so obvious. That was not expected at first. But from old storm windows and not knowing how they were put in originally. There was some unknown things that was learned from the job being completed. I will have the siding of the house slightly done to match really good for what I wanted later on. My only concern is better communication with sentri homes. Overall they were great when I did talk to them."

House Leveling questions, answered by experts

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.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking.

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.
