"I can't say enough good things about American A-1 Waterproofing. Roland and his team were amazing. I had originally opted to go with another contractor to install a French drain and sump pump, but after exposing the foundation, they got spooked and said they wouldn't perform the work. Roland came by and assured me his team could get the work done and they did not disappoint. Through the initial estimate, permitting, construction and final sign off, Roland and his team were communicative, prompt, clean, and extremely professional. It was an absolute pleasure to work with them!"

"The team at Blue Umbrella was fantastic from start to finish. We all worry about our homes and who we choose to do work, especially when it comes to big projects like these. Tony, Steve and the entire team were fantastic. It started with Tony, coming to my house and giving me all the information I needed to understand what was happening and how to fix it. I got busy, and they did a great job following up. Not being pushy at all, just checking in. When I finally had time to schedule the work, they were able to accommodate my schedule. On the day of the project, they arrived on time, were neat, and cleaned up everything when they were done. The process was quick and easy and I feel confident that this will solve my water problems. Don't waste your time getting 3-4 quotes... These folks are great and are worth every penny."

"I hired Cesar and his crew to gut and renovate multiple bedrooms a kitchen and 2 bathrooms. Cesar, Armondo and Benjamin were an absolute pleasure to work with. Their knowledge, expertise and craftmanship are top notch. Cesar is easy to work with and truly cares about making sure his customers are happy. Cesar has an uncanny knack for finding a solution to any problem he encounters. I found his pricing to be very fair and reasonable and I quickly learned I could trust Cesar. If you are looking to remodel, finish off a room or repair any part of your interior, Cesar and his team should be your first call."

"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

"I had a great experience with the asphalt shingle roof repair. The team was professional, arrived on time, and clearly explained what needed to be fixed before starting the work. They completed the repair efficiently, cleaned up everything afterward, and the roof looks excellent. The quality of the workmanship gave me confidence that the repair was done right. I would definitely recommend them to anyone looking for reliable and honest roofing services."

Foundation Repair FAQs, answered by experts

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.

It’s crucial to hire a foundation company that’s professional, experienced, and reliable, starting by choosing local experts with at least five to ten years of experience with your type of project. Local foundation companies will understand the soil and weather conditions in your area and can carry out the best solution based on your property characteristics. You should ask for a list of customer references, read through online reviews, and check for customer complaints and unresolved issues filed with the Better Business Bureau (BBB) before hiring.

Yes, foundation repairs are worth it if you have a significant problem or see signs that could worsen if not dealt with. If your foundation fails, your home can lose up to 20% of its value. Protecting your home from serious structural damage and avoiding more costly repairs later is well worth the money.

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.

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.
