"Outstanding! John took our vision and brought it to life in a way that went beyond anything we could have imagined. What could have been a simple repair turned into a complete transformation. The stonework they created not only improved the look of our home but made it stand out in the neighborhood. People keep stopping in front of the house to admire it. The quality, craftsmanship, and attention to detail are second to none."

"Jon is professional and a man of his word. My wife and I had some leakage in our finished basement. After substantial research, I contacted several companies in the area. Jon and his crew at Eastern responded faster than every other company and offered us the best price for the least hassle. The crew works hard and fast. They were respectful of our home and property and cleaned up after themselves when they were done working. Our interior foundation drain is working great and can sleep in peace knowing that our basement is dry, even on the wettest nights.They stand by their work and even came out to install a false floor under our oil tank after we replaced it., at no additional fee. I would 100% recommend Jon and his crew for all of your waterproofing needs."

Foundation Repair FAQs, answered by experts

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.

Whether you need a permit for foundation repair depends on your location and the scope of the work. Major repairs like foundation stabilization typically require a building permit, while smaller projects such as sealing non-structural cracks or applying waterproofing solutions often do not. It's crucial that your contractor follows all local building codes, as an inspector will review the work to ensure it's up to standard. Failing to obtain the necessary permits can create issues when selling your home and may lead to further damage if the work is not done correctly. Your foundation repair specialist will usually know if a permit is needed and can handle the process for you. You can also contact your local building department or municipal office to confirm the requirements and verify that your contractor has filed the appropriate paperwork.

If your foundation is unfinished, has surface damage, or is just plain unappealing, foundation refacing can be another great way to increase your curb appeal and give your foundation a fresh look. Used in conjunction with foundation planting, refacing can completely change the look of your foundation and your home. 

If your foundation repair claim gets denied, the first step is to carefully read over your policy and denial letter so you understand the reason for the denial. Then, gather evidence and documents that can support your case and appeal the denial with your insurance company. If your insurer does not eventually honor your claim, you may want to file a complaint with the insurance department in your state. In some cases, it may make sense to work with an attorney and file a lawsuit.

Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.
