"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"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 worked with Kevin recently on an addition to our home and a full interior remodel. We're very happy with how it came out. Kevin came in with reasonable pricing and we stayed on budget and finished relatively quickly. Kevin at times went above and beyond for us to get us to our desired aesthetic. He's always very willing to work with you to get to what you want to achieve. He makes himself available to answer questions and concerns. He has never once not called me back. Thanks Kevin for our beautiful home."

"Working with aright builders was an unbelievably satisfying experience …..Jorge and his brother Andy were consummate professionals and they accommodated every request and change order with positivity and good humor and never made me feel like I was asking too much. The finished product was better than I imagined it would be and they got it done in record time to accommodate my granddaughters high school graduation which was no easy feat with the COVID restrictions. I would highly recommend these guys for any home improvement project and if I need something done in the future these would be my guys."

"The contracted the work off to a third party. Jon took longer than expected. The windows was installed pretty good from the looks. Communication could have been better with knowing the job will take longer and what types of trims I wanted for the windows. As the contractor that was hired for this job by this company. Did a good job with putting up decent trim. As for the new windows they look great. I purchased the myself and hired sentri homes to install them. I will need to have a my siding on my house redone to be closer to the new windows so the gaps are not so obvious. That was not expected at first. But from old storm windows and not knowing how they were put in originally. There was some unknown things that was learned from the job being completed. I will have the siding of the house slightly done to match really good for what I wanted later on. My only concern is better communication with sentri homes. Overall they were great when I did talk to them."

House Leveling questions, answered by experts

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.

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.

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.

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.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation.
