"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."

"Budget Dry Waterproofing was great communicating appointments, the work to be done and the cost. The guy who came out to do the work putting in window wells at our house was very courteous and did the work in the amount of time estimated and explained everything clearly. I definitely recommend this company for your basement waterproofing needs and will consider them for any related job in the future."

"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!!"

House Leveling FAQs, answered by experts

A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces.

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. 

It restores concrete, prevents replacement cost disruptions, reduces trip hazards, and provides stability at a lower cost.

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

Address drainage issues, avoid heavy loads, and seal cracks to prevent future settling.
