"It went well - it is a beautiful product ( lift master) and operates like a charm. The installers actually took the extra time to go over everything with me and make sure it all worked properly before they left. Very happy and would definitely hire again."

"I had a great experience with Best Buy waterproofing. I contacted them for inspection due to water rising underneath my tile in the basement. They responded very quickly and had someone out for the inspection a day later. Ed completed my inspection and was very informative and communicative throughout the whole process. He didnâ t try to scare me into getting any services and was very patient with me. Any questions I had he was on it and available. When I made my final decision it was quick and a painless process. The crew cleaned up well and walked me through the work they had done. They installed a new drain and sump pump. Might I add they made my installation very esthetic by placing the line in the wall to hide the pipes when the dry wall is replaced. I will definitely recommend to friends and family!"

"I have waited some time to review as I wanted to make sure that we stayed dry and so far, we have! Always waterproofing has given us peace of mind that our home has been able to stay dry after flooding in our family room and master bedroom. I do recommend turning off your air or heat if they dig an indoor French drain as it clogged our AC unit. Estimate was quick, they squeezed us in ASAP after we had record rains and major flooding and gave us tips to help manage our water problems until they could arrive."

"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!!"

"Steve Norfolk (owner) returned my call quickly, came out to inspect my basement within 24 hours and gave me an estimate that was significantly less then another "national" provider.  He got me on his schedule promptly and his crew came out on time, performed the work, cleaned up after themselves and I have not had a water problem since that time.

Foundation Drain Installation FAQs, answered by experts

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Yes, many contractors offer warranties for their work. Confirm terms before starting the project.

The type of stormwater drainage system you need depends on your area’s storm severity and frequency. Your property’s location should also be considered, including the surrounding soil type, nearest roads, existing drainage systems, and slopes and hills. Your property’s structure, such as decks, walkways, crawl spaces, and foundation, also affects what drainage system will work the best.

Ideally, your sump pump discharge should run down a natural downhill slope 10 to 20 feet away from your home’s foundation. However, if your property is naturally flat, that might not be an option. Instead, you may be able to discharge it into a neighborhood storm drain or a nearby creek or pond. If that’s not possible, consider burying it underground.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.
