"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."

"As I did the first time I used Bob Lindsay's company, I waited six months to write my review. After withstanding nearly 13" of water from Henri and Ida, I cannot recommend this company enough. We used Bob at my first house and decided to use him again when our final walkthrough of our house revealed a wet carpet in the finished basement. Bob's guys replaced the shallow existing window wells with much deeper, galvanized ones, backfilled them with stone and piped them into a perimeter channel drain that was then flashed and cemented to the basement floor height. The sump pump pit was installed and a battery backup system was provided and wired in. The outside grading around the window wells was also redone to slope any surface water away from the foundation. Due to our Radon mitigation system, a polyurethane caulk was also used to seal the system. We remained absolutely bone-dry these last few weeks despite rain falling at 2-3" per hour in some cases. The work is efficient, his guys are extremely friendly and skilled, and despite the messiness of the job, they do a fabulous job cleaning up. There is a certain peace of mind that having this type of work done provides, and you cannot put a price tag on it, especially if you plan on finishing (or refinishing) a basement. At the end of the job, Bob was even kind enough to have one of his guys tie in a 2" piece of PVC from the floor with a cap (which I then drilled a hole in) so I can run my dehumidifier constantly without ever having to empty the bucket. We have since refinished our basement to our liking and know for certain that this was the best home investment we could have possibly made. A friend of ours has also done her entire basement with Weather-Tite and had an equally wonderful experience. Thanks Bob for saving us not once, but twice."

"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

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

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.

Cement companies offer a wide variety of services, including delivering and pouring concrete for home foundations, walkways, patios, driveways, concrete steps, pools, pool decks, and more, plus concrete repair and patching. Most companies also have the ability to demolish and haul away old concrete landscaping features. It’s a good idea to reach out to a few different companies before hiring to make sure you choose one that can tackle the entirety of the project you have from start to finish. This method will typically save you some money over hiring multiple contractors.

Foundation repair can affect home value positively or negatively. If you address the underlying issue and hire a foundation repair contractor to complete the work—especially one that includes a warranty for the work—then your repair will likely increase your home’s value. If you fail to pull proper permits and cannot prove that a licensed expert completed the work, there’s a chance buyers will view your home in a negative light and end up offering less for your property.
