"We needed a reliable contractor to fix problems with our foundation. Lux Foundation Solutions was recommended to us based on previous work by the West Virginian realtor we worked with for our house. First, Matt came out, performed an assessment and explained everything well. He was friendly and answered all my questions about the work being performed. That set the tone for a great experience! After the estimate was received I made an appointment. The day of the appointment Adam’s team arrived exactly on time: I live somewhat remote and that his team was on time really speaks for the company and it’s work culture and ethics! Adam and his team worked in the crawl space, which was difficult for me to get into. Adam kept me informed throughout the process and even took pictures after the job was done to show me the results. The quality of the work speaks for itself! I’m very happy to have hired Lux Foundation Solutions and they are my first company to call if another job needs to get done! I highly recommend the company for your crawl space work!"

"Mauricio and Crisjan were the initial sales reps who came to examine the issue and they took the time to test drainage that might have potentially been creating the water issue. They offered a reasonable solution (sealing the visible cracks and holes in the concrete and I was contacted within a couple of days with an estimate and scheduling options. Sean was our tech and he did a fantastic job diagnosing the issue beyond just the cracks. He not only address all the holes and cracks in the concrete and mortar, he sealed up additional entry points above the foundation. He sourced additional materials to cover openings for cable lines. He went above and beyond and gave us measured information on how we should continue to monitor and treat this area as the house settles. He was thorough, informative, and provided excellent service in his work. I'm very glad that Sean was the technician sent to us and I would specifically request him for your projects."

"Howard Glancy came to inspect cracks in my home's concrete walls where the foundation was sinking. He, as a Certified Field Inspector, went over the whole house with me, explaining why the walls were cracking, and what should be done to alleviate the problem. Howard explained what JES Foundation would do, approximately how long it would take, and provided a quotation for the repairs. Besides raising the problem walls and ensuring they would be structural sound and guaranteed to stay that way for the remaining life of the house, he also advised me of how JES would repair minor cracks in the remaining building as well as having s sump pump installed to wick away any ground water from damaging any other parts of the structure. Mr. Glancy was very courteous; knowledgeable of his profession; and walked us through any questions we might have had concerning the processes. Due to the permit process taking so long, the work on the house won't start for a few months, and if Mr. Glancy is any indication of the professionalism of the rest of the JES Foundation personnel, I'm confident that the work will be done properly, in a timely manner and to my complete satisfaction."

"This past year, as we were removing the old wood paneling in our basement, we found a diagonal crack along one of our exterior walls. If a crack in a wall is not terrifying enough we had signs of previous water damage and the possibility of a crack in the foundation. We called AA Action Waterproofing to give an assessment and these guys were thorough. Robert spent 3 hours explaining in detail the process by which the damage occurred, the methods to repair said damage, and the steps necessary to maintain the integrity of the basement. He then followed up with a comprehensive report a day later. Based on the quality of this initial assessment we decided to go with them and could not be happier. The work crew lead by Marvin was timely, polite and efficient. They installed an underground drainage system, repaired the wall with carbon fiber slats, and underpinned the rear portion of the house. Unlike other contractors, AA Action provides a guarantee for their work. They are also very easy to work with, prompt with paperwork, and always willing to answer questions. We strongly recommend this company for their service and quality workmanship. Thank you Robert, Marvin and Rhonda."

"My experience with this company was great. I was able to tell them my issues and they gave me several options. Ultimately we went for the full French Drain system. Everything was done on time and the estimates were very fair. Warranty on the work is great. I would call them again if needed."

"I was having some issues with water coming into the basement through the foundation and walls during rainy weather. Not flooding, or even shop vac-able volumes, just enough to be annoying and require mopping. Dominic and his crew were here today to install an under-floor drainage system and a new sump pump. I was dreading the demo (I have a concrete floor) and the mess involved, but these guys came prepared for everything! They used dust abatement measures to protect all my basement-stored items, and they removed and hauled all the debris away when finished with the excavation. What really impressed me was the concrete restoration upon completion. I've previously had a sewer line replaced through the basement floor, and the contractor really "botched" the floor repair. I can't describe how different this experience was! The concrete installed today is immaculate! Dominic takes pride in his work and with good reason! The new concrete is perfect! I am thrilled!"

"They fixed two leaking cracks in the basement exteriorly in May 2019. Also, they regraded the patio so that the rain water runs away from the house. I am happy with their works. I am glad my basement is dry now. Thank you."

"I could not recommend DES enough! If you have any kids related to keeping your house, safe from water, you must talk to Mark Lane. We had four contractors assess and recommend solutions. All of them were more expensive and none gave us the confidence he did. The work was done under the time estimated and for the exact amount of the quote. Mark came three times to check on progress, and even gave us some groundcover to plant for holding the new soil in place. We recommended our neighbor have DES repair his drainage and water intrusion issue and he was extremely satisfied as well!"

Foundation Repair FAQs, answered by experts

Barring extreme home foundation problems, most horizontal foundation cracks are fixable using one or more methods. Most of the repair methods require professional expertise to accomplish, and include plate anchors, steel reinforcement, soil anchors, reconstruction, or carbon fiber strip applications. Contacting a professional to diagnose the problem early can minimize repair expenses.

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.

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.

Yes, all basement floors crack in response to the natural settlement of the soil around them and from concrete shrinkage as it cures, and you’ll see hairline cracks as a result. However, you should keep an eye on your basement floor to see if cracks continue to lengthen or widen or show signs of water intrusion. In any of these cases, the problem is likely not settling or shrinkage, and a professional repair is necessary.

The actual foundation repair costs will depend on the extent of the damage, how many blocks you need, labor costs, and material costs. As an estimate, the average repair costs for a cinder block foundation fall between $350 and $25,000. Because the range is so large, it’s important to call a professional foundation repair company and have them assess the damage and estimate the repair costs.
