"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."

"Full waterproofing of the basement in our 95 year old house, including demolition of walls and shelves/cabinets/sinks and plumbing. Additional service of adding a footing to the basement walls. All the work took three days. Excellent work and looks great, though a bit costly."

"I hired Progressive Renovations to repair many cracks in my concrete patio area and level off the cobble stone walkway to my front door. Sam and his crew did a fantastic job. I am happier than ever with the quality work. His crew is great."

"Ani and Igli from Solid Choice Construction are truly exceptional contractors. They recently rebuilt our deck, and the transformation is stunning — the craftsmanship, attention to detail, and overall quality exceeded every expectation. Beyond their skill, they are incredibly personable and easy to work with. They communicate clearly, and carry themselves with a level of professionalism that immediately builds trust. They’re already lined up to renovate our closet next, and based on our experience so far, I have full confidence it will turn out just as beautifully. I would recommend Solid Choice Construction 100% to anyone looking for reliable, talented, and genuinely great people to work with. Thank you both so much for such an amazing job!"

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.

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.

Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete—it’s a budget-friendly option suitable for DIY enthusiasts.

A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.

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.
