"We recently had our basement waterproofed by the American A-1 Waterproofing Company, and I couldn't be happier with the job they did. From start to finish, the team at American A-1 Waterproofing was professional, knowledgeable, and dedicated to ensuring that my basement would be completely waterproof. First, the team came out to assess my basement and provide me with a detailed estimate of the work that needed to be done. They took the time to explain the process to me, answer my questions, and address any concerns I had. I felt like they really listened to my needs and customized their approach to fit my specific situation. Once the work began, the team was punctual, respectful, and efficient. They took great care to protect our home and belongings, and they kept us updated throughout the process. They worked quickly but thoroughly, and we were impressed by their attention to detail. The waterproofing work itself was top-notch. The team used high-quality materials and techniques to ensure that every nook and cranny of my basement was completely sealed and protected from water damage. They also installed 3 sump pump and created a French drain to further safeguard our home. A-1 did a great job waterproofing our flooded and leaking basement. They kept coming back as bigger rainstorms showed smaller leaks and waterproofed the inside and outside until stayed dry. Overall, I highly recommend American A-1 Waterproofing for anyone in need of basement waterproofing services. They are professional, knowledgeable, and dedicated to ensuring customer satisfaction. Thanks to their hard work, I now have a safe and dry basement that I can enjoy for years to come!"

"The previous owner of our property used his French drain installation as a selling point, but shortly after we moved in we found water in the basement after a storm. It turned out that the "French drains" were a trench at the edges of the basement and a sump pump. The drains were not piped to the sump pump. We had Arid install real French drains with pipe to the sump pump well. Thus was in 2005 and we have not had any water in the basement since. Pat explained the job well and his team performed it quickly. They cleaned up well afterwards. The pump finally gave out last night (after almost 12 years). Arid is going to install new one on Friday."

We called Lou and he made a stressful situation a lot more easier to deal with. He let us know step by step everything that needed to be done and he was very responsive and answered all of our questions. We highly recommend them!!"

"Weather-Tite was recommended to me by a contractor who I trust to evaluate and repair water and moisture issues that I was having in my garage. Bob and his crew did a phenomenal job!! My husband and I are beyond thrilled with the results! They are professional, courteous, and fastidious. Half of my garage is underground, as there is a hill in my front yard leading up to the house. The repair involved excavating dirt along the front of my house next to the garage foundation wall down to the drain pipe, repairing cracks and holes, applying waterproofing and more. The interior wall was cleaned and drylock masonry paint was applied. My landscaping on the outside had to be removed and then put back. They did such a good job that you couldn't even tell it had been moved at all. We also had Bob and his crew complete a second job for us. This involved excavating another trench but in the back of the house along 16 feet of the foundation, replacing a drain pipe and waterproofing. They were at our house for three days. During that time and after we had torrential rain and everything stayed dry!!! I highly recommend Weather-Tite Waterproofing, Inc.!"

"We had French drains installed around the whole perimeter of the basement. They were very professional from start to finish. Very fair quote and to be honest the best we recieved. On the day of the project, Tony who had given the quote was there to walk us through everything and get it all going. Even Steve the owner came out and checked in with us. The crew was great. They answered any questions we had, were very hard working and left the house cleaner then they found it. Overall a great experience."

"I am not yet able to determine whether or not the expected results of the basement waterproofing work is satisfactory as I have not had a rainstorm or heavy rain since the basement waterproofing work was performed. I will, however, pay great accolades to Quality 1st customer service, especially to Kyle. I was troubled with the proposal for the job as certain aspects of the language would have left me at an unfair liability should something had gone wrong with the work. I explained this issue with Kyle who followed through until the proposal was acceptable to me. The work crew was exceptional in that they were punctual, worked quickly, neatly and were, without question, among the hardest workers ever to have done a construction project for me. The crew was headed by Wilver along with his guys - Manuel and Jose. Again, I will refrain from commenting on the expected results of the work performed until the appropriate circumstances occur. In summary, I would say that Quality 1st demonstrated A1 customer service and the crew that performed my basement work were hard workers with great attitude."

Basement Waterproofing questions, answered by experts

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.
