"KN Remodeling redid my floors, removed a wall and got my JADU permitted, plus many more random fixes. Whatever project I threw at Nathan and his team he got done. They were great and I would use them again."

"After dealing with frequent roof repairs, we finally decided on a complete replacement for our Livermore home. Avi kept us informed every step of the way, and the finished roof exceeded our expectations. It's made a noticeable difference during hot summer days."

"This is THE company to use. I had an old 1907 wooden house sitting on a decaying brick foundation and needing a sister foundation installed and a complete seismic retrofit. Even during the bidding process, Brad from Alpha was extremely attentive without being assertive. I contacted four other companies although one I eliminated since they charged a fee for inspecting. Alpha was very timely with their bid and flexible when I needed help with the budget. All the way through the process, every single person at Alpha was extraordinarily good at customer relations, returned emails immediately, and stayed in constant contact throughout the entire process. Whenever there was a slight change to the original plan due to permitting or a plumbing adjustment, Alpha was very proactive and made sure everything was communicated clearly and promptly. I have really NEVER worked with a company that had such excellent communication skills. This is really one reason I selected them to do the work and, even though they may not have been the least expensive, it is worth the extra price for this reason alone. And Alpha Structural's work speaks for itself as well. Everything was done precisely and well beyond code, an unbid section of foundation was provided under the front porch without increase to the budget, and all materials used were of the highest quality. The project went on somewhat longer than estimated due to permit changes and a short weather delay but was still finished in a timely way. My home is our family's largest asset and it is a great relief to now know it is sitting on a solid foundation. The entire process from first to last was excellent and I cannot say enough good things about the way Alpha Structural handled the project. From the front office to the boots on the ground: A++"

"Was contacted directly by Phil quickly after submitting my info. He was at my house the next day. We had him transform our kitchen and bathrooms. He was very professional and prompt with communication. He worked with my wife on all the materials and textures and even finished 2 days earlier than quoted. Very happy with the services and will use Ramapo again!"

"We had an addition built into our home to accommodate our growing family. We were a little nervous about having contractors in our home as I was pregnant at the time but the guys from RS Construction could not have been more professional. They always made sure things were kept clean and safe around the house as they worked. They did a beautiful job with the addition and the price was very fair. I highly recommend their services."

"Karl knows what he is doing and has the right key support. The house that he built us demonstrates lots of attention to detail. Price was reasonable and he works right along with various phases and can keep you in the loop, all the way. I will be hiring him for future builds. He seems to have a solid relationship with the city; he is a seasoned professional. Definitely recommend this man."

House Leveling questions, answered by experts

The average cost for mudjacking is around $1,200, though prices can range from $300 to $3,400. On a per-square-foot basis, you can expect to pay between $3 and $8, with an average of about $5 per square foot. The final cost depends on several factors, including the square footage of the concrete, the type of slab, its accessibility, whether it is load-bearing, and the type of material used to lift it. Generally, lifting a driveway, small patio, or sidewalk is less expensive than lifting a slab foundation or garage floor.

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.

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.

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.

The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ.
