"They were good. Matt was our inspector. We needed to get an inspection done on a new home and they came out with little notice and gave us a great breakdown and report. We are looking to hire them for the foundation repairs so I will let you know how the service goes beyond the inspection!"

"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"I couldn’t be happier with Amir, I am glad that I found him. I’ve been dealing with many contractors and they all have been unprofessional, dirty, and they slowly neglect the job to work elsewhere, leaving mine incomplete. I’ve had to be on top of them just to get the work done, they would usually show up when it was time to get paid. I had lost faith with all contractors, that is until I found Amir. He is the opposite of what I’ve dealt with, professional, to the point, honest and works cleanly. He recently paved a four garage driveway. He got the job done so quick, that my head still spinning, not only that, when I showed him the respective area, he took the measurements, got on his phone to run some numbers, and made an impromptu quote. We picked the dates and the job got done. No B.S. no chasing after Amir. DONE!!. He is currently working on a historical home for me. I will come back and add additional details about my experience with Amir once the whole job is completed, but, as of right now, I am extremely happy. The work is getting done, and quickly. The foundation work started with in a couple of days after we signed the contract. If this was a different contractor, I can positively say that I would still be waiting for the work to begin. If you want to have a horrible experience, do not hire Amir, because you will only have a good, professional experience. Amazing work Amir."

"Sept 2020 =Paramount Pavers replaced our ugly cracked circular driveway with beautiful Belgard pavers. We selected Paramount pavers because of the excellent reviews on Angie's list. Isaac was always responsive and answered many of our questions. Can't find many contractors like him. The employees consistently came to work for 10 days. They did a beautiful job. Minor issues: the transformer to the step lights had to be replaced after 2 days and broken sprinklers were replaced. Highly satisfied. Highly recommend. See also my Yelp review that included pictures."

"Etan Home Construction was a pleasure to work with. Ed, Richard, and crew installed the foundation for our single-family home. Excellent attention to detail and quality of work; Ed caught a discrepancy made by our civil engineer and surveyor, which would have been an incredibly costly error. I could not be happier with the end result, I highly recommend!"

Foundation Repair FAQs, answered by experts

Yes, you can replace a cinder block foundation. If a block foundation is too severely damaged to repair cracks and other issues, replacing the entire foundation is a viable option. The job will require a professional and can take between one to seven days on average to complete, depending on how complex the problem is.

You can buy a home with foundation issues, but understanding the extent of the problem and what solution you need is critical. If you learn that a home you’re trying to buy has a foundation problem, it’s not necessarily a deal breaker, but you should have a professional assess the issue to see how severe it is and know when to walk away from a foundation problem. Foundation issues can necessitate simple and affordable solutions or complex work that costs thousands. 

Yes, a house can collapse from severe foundation problems if they are left unchecked. However, this is a rare occurrence that typically takes many years to develop, and a partial collapse is more likely than a full one. Homes on hillsides or in areas with frequent washouts are at a higher risk. Barring a natural disaster or other extreme circumstances, clear signs of major issues will be apparent long before a collapse is imminent. It is crucial to conduct routine foundation inspections and address any problem, no matter how minor it seems, as soon as possible to avoid threatening the structural integrity of your home.

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

Yes, thicker concrete is less likely to crack. The thicker the concrete is, the less susceptible it is to extreme changes in weather conditions that often cause concrete to crack or chip. If you’re unable to install a thicker concrete driveway for any reason, you can also ask your professional to install more rebar or wire mesh to provide greater strength and better resilience to damage.
