"We hired them to build a retaining wall to level out our sloped backyard and install a new patio. They recommended natural bluestone bordered by classic bricks, and wow?what a difference! The stonework is flawless, perfectly level, and handles heavy rain with zero drainage issues. It looks like a high-end resort back here now. Worth every penny."

"I have worked with Uprise twice now and both times they did great work. The first house they found and repaired a leak, and in the second house I had them install a new roof. I would not hesitate to call them again for future needs."

"Honestly speechless with the work that they did on my house, everything is just so unbeatable compared to other companies. Their prices are amazing and they clean up around the house very well. It?s like they come, work very hard, leave and it looks like they were never here. The new roof looks amazing and I will definitely be recommending this company to my family and friends."

"Extremely knowledgeable and highly professional. Would never even think of using/hiring another waterproofing company. Elaborate waterproofing system put in by this company that has allowed us to breathe easier during flooding rains. They fully understand water flow, slope, and all aspects of keeping the inside of our house “dry”. Lou and the group are tremendous and care about the product they produce."

House Leveling questions, answered by experts

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.

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.

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.

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.
