"The contractor and crew did a fabulous job of installing a permeable paved driveway and retaining wall. They were respectful of me, my time and property. They kept me updated and explained each phase of the project. I’m very very pleased with the company and the completed project. I highly recommend this company and would definitely use them again."

"Jose and his crew installed a~360 sq. ft. patio using Nicolock pavers and contrasting charcoal border pavers in 2.5 days. Outstanding job. When I asked them about using edging to prevent the pavers from shifting, I was told that he does not use edging. Instead the perimeter is first installed as retaining wall blocks set in mortar! After the perimeter is set, the site is then excavated, compacted, covered with weed suppressing fabric. The fabric is then covered with crushed stone layer, compacted and sand is then laid on top, compacted and leveled and properly graded. I chose the herringbone design shown in their logo and very happy with the choice. The border pavers are laid on top of the retaining wall blocks and are "glued" to them using mortar/liquid cement. After the border pavers had set, the crew applied polymer sand to fill in the gaps between pavers. This "grouting" was done twice. The final product is solid as a rock and not going anywhere! VERY HAPPY WITH THEIR WORK. Jose Espinal's company is insured and bonded, so hire them for your project and be worry free."

"Daniel and his partner installed new appliances and tile in my kitchen, I had new counter tops installed as well in my kitchen and master bathroom. I also used John Krause for a repair to my shed from water damage again Daniel and his partner did an excellent job for me. Very please with Daniel and his work. I believe Daniel is a sub-contractor for John Krause, but none the less in my opinion he did really good work and communicated with every step of the way."

"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!!"
