"Exceeded my expectation with waterproofing my entire basement + window wells. These guys are the real deal! I worked with Rob and I was educated and all my concerns were addressed. They do it right by you, the contract missed a window well and they were able to addressed that without having to go through a whole new quote/contract. Helped move some furniture around and left the place clean."

"We had a great experience hiring '58 Foundations to waterproof our basement! Lon was our salesperson, and he came and explained the work that would be necessary to ensure that water would never flood our basement again. We appreciated him taking the time to explain how the whole process worked, and providing us with the option to finance the project to make it affordable for us. We had Brett Boyles and his crew, John and Clarence, come to do the work, and they did a fantastic job! Brett even came to show us the progress in the middle of the project and explained every detail of the work that was being done. He was very professional and we appreciated how he gave us peace of mind about everything once the project was completed. I would highly recommend '58 Foundations for anything basement-related. We appreciate your business - thank you!"

"My husband and I came across 7th State Builders online. Eddie came out to our home for our initial consultation. He was punctual and professional. He listened to our vision and took the time to draw out a plan and explain the process. He was very knowledgeable and made some great suggestions. We decided to do a big project at our home. For the back: a rebuild and waterproofing of our previous deck and a large patio to go underneath it with a fire pit and sitting wall. The front of our house needed some repairs so we had them redo our sidewalk in the same patio pavers from the back. The whole area in front of our garage was cut out and they put in new concrete and leveled it out. They rerouted our gutters to prevent flooding as the previous design was doing damage to our foundation. The owner, Chase, was very hands on and kept us updated the whole time. He frequently made sure we were happy with the way things were going. The whole team made this project an enjoyable experience. Iâ ll admit, my husband and I can sometimes be difficult people to please-But wow!! They really knocked it out of the park for us! 7th Stateâ s precision and talent is unmatched. You are truly working with people that know what they are doing and they are the best at what they are doing. Communication from start to finish was consistent and open. They were very patient with our ideas and they added to our vision in ways we didnâ t think was possible. The whole crew was professional and extremely hardworking. Not only did they do an amazing job but you can tell this is their passion. The little touches they put on everything are amazing. The details they put in set them apart from the rest. On every area of this project they went above and beyond. The transition of starting another area after the completion of another was seamless. Once they had completed our deck they immediately came in and started working on our patio, and so on. They did not miss a beat. When you are working with 7th State you are truly working with the best in the area. We will use them again in the future and we recommend them to anyone that wants true quality and a modern take on what you are looking to do. Thereâ s nothing they canâ t do! Thank you 7th State for making our vision a reality!!"

"Roland jr and his crew from MD Waterproofing did a great job under difficult circumstances. A previous renovation by a previous owner dropped the basement floor. What we didnâ t realize is that they had never added underpins so the foundation was undermined. Once Rolandâ s crew broke into a wall to solve a leak, they saw this. They explained the issue clearly and explained the remedy. We were able to quickly get a new quote for the additional work from our company contact, Steve Maney, who was very professional throughout this. Total cost for our house was just over $20k for underpinning two walls and redoing the associated French drains. We will definitely go with MD Water proofing to finish the last two walls, once we have the money saved"

"Had difficulty nailing down date for crew to come out and install new sump pump & trench. Once we nailed it down, they arrived at said date of service and did the work quickly, efficiently, and professionally. However, they left a lot of dust and smeared mud on the floor of our basement. It took almost 4 hours to fully mop everything up and wipe everything down."

Basement Waterproofing FAQs, answered by experts

Periodic inspections and addressing drainage issues prevent further damage.

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation.
