"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

Underpinning is a specific type of foundation repair where a specialist installs deep piers under a foundation to provide additional support. This method is often used when the soil beneath the foundation can no longer evenly support the structure. Foundation repair is an umbrella term that includes many methods. Besides underpinning, other common repairs include foundation crack repair, waterproofing, cosmetic repairs, and concrete block wall stabilization. Often, underpinning is accompanied by other work to address the root cause of the foundation issue, such as regrading the yard to ensure water drains away from the house.

No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.

Not all cracks in brick indicate foundation problems. For instance, small hairline cracks can occur as a new construction settles. However, larger cracks are often a sign of a more severe issue. Indicators of a potential foundation problem include long horizontal cracks, "stair-step" cracks, vertical cracks that appear indoors, or any crack that widens at the top. Other signs of structural damage to look for are uneven floors and doors or windows that stick. These issues could be caused by problems with the soil beneath the home or an overgrown tree.

If you don’t have any access to or knowledge of any area underneath your home, chances are it’s built slab-on-grade. You can also look for the concrete around the bottom edge of your structure; if it’s just a few inches tall, it’s likely a slab. If it’s more than that, has any windows, or you have steps leading to your main entrance, you likely have a different foundation style.
