"We just finished a four bedroom/ three bathroom full remodel in Santa Monica. We are very happy with the end result. Nathan, who is the owner, was very involved in all phases of the job. Nathan got the job done on time. The workmanship and attention to detail was great. He had good communication and relationship with his team. Whenever we had a concern or question, Nathan was easy to get a hold of and handled it quickly. We were worried about the process of a remodel with all the stories you hear about bad experiences. But Nathan made this so easy on us and we would definitely use him for any future projects."

"We found McCormick home builders through Angie’s list. They were not one of our original contacts, but they contacted us and came out to give us a quote. Matteo was extremely helpful, informative, honest, and gave us reasonable realistic prices, and did not try to inflate the prices or pressure us in anyway. We felt very comfortable with him immediately. We felt like he was a member of the family that we could just talk to and ask questions he was very personable. He gave us his contact number in case we had other questions and he was always available when we needed him for any type of questions or concerns. Mateo‘s team did a beautiful job. They were fast. They were efficient. They cleaned up beautifully. They did a wonderful job. They were very considerate of our time our needs and our neighbors. They were an absolute pleasure to work with. I would highly recommend Matteo from McCormick home builders for any home building projects, and we will be calling him again in the future!"

"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++"

"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."

"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!"

"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

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.

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.

Yes, you can mudjack cracked concrete, but the cracks will need to be repaired once the concrete has been leveled. If the concrete is severely cracked in multiple places, replacement may be a better option, but for less severe cracking, mudjacking is a good solution as long as cracks are correctly caulked and sealed.

Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.

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.
