"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."

"CT basement did a phenomenal job finishing our basement and we could not be happier with the results. They made every step of the process from design to the finished project simple and straightforward, everybody was easy to work with and made our opinions and needs the top priority and they were able to perfectly translate our vision into the final product. This was a fairly large project involving finishing 1200sq ft with an office, gym and full bathroom and their experience and expertise was obvious. They definitely understand the specific needs of a basement while making it look like any other room in the house. We would use them again in a second, we’ve even been joking about tearing down the rest of the house and just living in the basement!"

"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!!"

"Vincent did an absolutely beautiful job on my cement and asphalt driveway. Their craftsmanship was top-notch. They finished the job quickly, and left the work area clean when they were not there. They stayed in touch throughout the process, and they take tremendous pride in their work. I have worked with hundreds of contractors over the years and these folks are among the very best and most reliable. Cannot say enough good things, also the prices were competitive, and they delivered a better quality of work than I would expect for a similar price."

"Excellent basement waterproofing service! The team was professional, knowledgeable, and worked extremely hard from start to finish. They explained everything clearly, repaired the problem areas, waterproofed the basement properly, and left everything clean when the job was completed. The difference has been amazing ? our basement is now dry and protected, even after heavy rain. Great workmanship, reliable service, and very fair pricing. I would highly recommend them to anyone needing basement waterproofing or foundation repair."

House Leveling questions, answered by experts

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

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.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.

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 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.
