"OUTSTANDING! This company is so honest and leads with great integrity that the inspector Tony identified the root cause of where our water was leaking into our basement and said we may not need to install French drains which would have cost us about $4,000. Our previous owner drilled holes into our sidewalk outside of fireplace that leads to our basement for termite treatment. The cement covering holes eroded and water was leaking into the basement. We covered the holes with cement 2 days ago and with this passing rain not one drop of water is in the basement. We've had three other basement waterproofing companies come to her house and no one noticed it except for blue umbrella waterproofing. The owner even took the time to call me to ask how the inspection went. This is the only company I would use in the future."

"Those of us in Jersey can attest that the rain has been super problematic this year. After ten years in my home, my basement was flooding consistently. I contacted Bob at Westher Tite as well as 2 or 3 other companies for emergency diagnosis and repair. Bob was the first to reply, very informative and had the issue fixed within the week! He and his crew were punctual and professional. Once the work was completed, my basement was spotless. No signs of moisture or dust anywhere! Bob was helpful in explaining everything. Pricing was fair not the most nor the least expensive estimate. The VALUE, however was spot on! The rainfall hasn’t let up a bit and not a drop of water in my basement."

"The company is located in Ramsey NJ

The original inspection was completed for the original cost. The additional work, a check valve was performed on the same day the tech explained that this would prevent the back- up into the slop sink. However as the tech explained this is only a temp fix. We discussed different alternatives and his Boss , mr Fusco was suppose to call me with prices. He never called.
The tech who came was very polite and seemed knowledgable
For this reason I would not rate this provider as reliable

Foundation Repair FAQs, answered by experts

You can patch minor cracks and damage yourself using concrete fillers or mortar. Larger damage may require full replacement of affected slabs. However, water damage to your concrete will never disappear unless you address the root cause causing the water to cumulate. To prevent future damage, you can also waterproof your concrete.

You can buy a home with foundation issues, but understanding the extent of the problem and what solution you need is critical. If you learn that a home you’re trying to buy has a foundation problem, it’s not necessarily a deal breaker, but you should have a professional assess the issue to see how severe it is and know when to walk away from a foundation problem. Foundation issues can necessitate simple and affordable solutions or complex work that costs thousands. 

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.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

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.
