"It was a complex project. They were very careful with their procedures and raised sunken concrete sections next to the house and around a pool to allow for drainage. They filled the major cracks. They were courteous and on-time over several days. After many years the water in the basement problem has been resolved."

"Capital Chimneys and Masonry Repairs contacted me the same day i requested a quote, and were able to visit to provide a quote within day or so. They then visited, and completed the chinking on an outside wall, repaired a wall in the basement, and were able to install a gutter to ensure the water no longer damages that wall. They also pointed out future repairs that would be good to do in the future, but not urgent. They also pointed another wall in the basement. The three masonry repairs, as well as the gutter, were installed with professionalism and skill. I look forward to working with Capital Chimneys and Masonry repair again in the future."

Foundation Repair questions, answered by experts

Mudjacking is usually reserved for light-duty slabs, like patios, driveways, and sidewalks. However, it can be an effective way to lift garage slabs and concrete around the perimeter of the home, which could harm your foundation if it’s not done properly. The risk of damage is why having a professional mudjacking company carry out the work is important. This type of slab or foundation repair is relatively inexpensive, especially if you consider that a DIY job requires that you pay to rent the necessary equipment.

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.

Concrete spalling can be fairly serious, especially if left untreated or in a public area. It can be a tripping hazard and, if not resolved, can lead to structural instability.

Although it is possible for a house to collapse from a sinking foundation, it will likely take many years, and signs of major issues will be apparent for a while. Homes on hillsides or in areas that experience frequent washouts are at a higher risk of collapse. Still, barring a natural disaster or extreme circumstances, houses are unlikely to fully collapse from foundation damage.

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.
