"I am not pleased with the service I received! They damaged my waterline and stated someone would be out to fix it. It's been 9 months and no one will return my calls nor have they come to fix what they damaged! They ruined my lawn and never came back to replace the soil they dug up! They ruined my basement floor and I had to replace my entire floor! They said they would be out to test the sump pump and drains that were installed, again, it's been 9 months and no one has followed up with me! I'm really concerned that the lifetime warranty they say I have even exists!"

Construction company and consulting engineering firm for residential, industrial, commercial, institutional, and retail clients.

"Had Betts Structural Engineering come and look at the foundation of a house we were in contract on. Josh came out and was professional and informative. He informed us the foundation was failing and explained what needed to be done. He throughly explained everything and told us how we could do it ourselves for much cheaper than a contractor could do it. In the end he saved us from a long and expensive process if we proceeded with the house."

26 years in business ...All waterproofing methods available...50,000 satisfied customers....

"This company is a joke. Steve is a snake oil salesman who pressured us into a $10k job. He came out and misdiagnosed the problem resulting in him switch the plans several times. When it came time to get the work done, my brother and I had to finish the job. If your job is to take water from the foundation how is exterior work not included in the quote. Furthermore, Steve has ZERO man management and LIMITED knowledge of his field. His crews have no idea what they're doing, and his front office is a joke. I had to explain to them that they do indeed make male pipe fittings despite Steve and his associates persistence that they don't. If it's a choice of having water in your house or working with these jokers l'd recommend just letting the house fill with water. Pathetic, unprofessional, and a waste of time and money. SMD Stevie."

Foundation Repair questions, answered by experts

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.

Home foundations are designed to last a lifetime when properly constructed and well-maintained. A poured concrete slab can last 200 years, while concrete blocks can last 80 to 100 years. A pier foundation can last about 75 years. Brick or stone walls can last 100 years or more.

Underpinning is a type of foundation repair in which a repair specialist installs piers under your foundation to provide additional support for the concrete and structure above. Foundation repair is an umbrella term that includes many other repair methods, including foundation crack repair, waterproofing, cosmetic repair, concrete block wall stabilization, and more.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

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.
