"We had Arnold and his team repoint the mortar in the stone foundation of our old (around 200 years) house. They did a wonderful job and it looks fantastic. They worked quickly and were very personable. We look forward to having him back during the winter to fix the inside!"

"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!!"

"Outstanding! John took our vision and brought it to life in a way that went beyond anything we could have imagined. What could have been a simple repair turned into a complete transformation. The stonework they created not only improved the look of our home but made it stand out in the neighborhood. People keep stopping in front of the house to admire it. The quality, craftsmanship, and attention to detail are second to none."

House Leveling FAQs, answered by experts

Most projects take 1-3 hours, with immediate usability after completion.

It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.

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.

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.

Concrete leveling is not typically covered by insurance. In some cases where the shifting concrete is caused by a natural disaster or storm, you may be able to file an insurance claim if your policy specifically covers those circumstances. In most cases, though, you’ll pay out-of-pocket for concrete leveling.
