"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

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.

Not all cracks in the basement floor signal foundation problems. As the house settles, you’ll notice very thin hairline cracks, which you don’t need to worry about. Cracks that are 1/8 inch or wider should require sealing, while ones that are 1/2 inch or wider require leveling. However, if you have cracks in your basement floor with heaving, you should call a pro to assess the situation. Heaving can lead to uneven flooring, structural issues, and foundation problems.

New constructions need time to “settle” and sometimes, small hairline cracks occur as a result. Larger horizontal or “stair step” cracks, however, are usually a sign of a deeper, more severe issue. It could indicate an issue with the soil beneath the home, a problem caused by an overgrown tree, or another problem.

Foundation repair costs $250 for a minor crack that doesn’t affect the structure’s integrity, although it can cost as much as $800 if it’s a major crack. Call a pro to get it fixed as soon as possible if your crack is bigger than 1/8 inch wide. Additionally, if you need to seal the foundation to fix leaks, it can cost approximately $2,000 to $7,000.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
