"Bill and his crew exceeded our expectations. Both our water damaged basement and our failing garage foundation required a change in course and they communicated options and provided excellent and economic solutions. They arrived early and stayed late 6 days a week to work around our weather. They provided extras as we went along and worked through some tough weather conditions. The daily communication was the best. Their prices saved us so much money. Their clean-up left our place in better condition than when they arrived. This company is going places. We will use them for any future needs."

Foundation Repair questions, answered by experts

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.

It depends on the severity of the damage, lasting from a few days to several weeks.

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.

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.

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.
