I had a great experience working with Junior López. He was professional, reliable, and paid close attention to detail throughout the project. The work was completed with quality craftsmanship, the job site was kept organized, and communication was clear from start to finish. He took the time to answer questions and made sure everything met expectations. I would definitely recommend Junior López to anyone looking for a trustworthy and skilled construction professional.
I highly recommend J Lopez Construction Corp. Junior and his crew built my pool deck, and the entire experience was outstanding from start to finish. Their craftsmanship was excellent, and the attention to detail really showed in the finished product. Every aspect of the project was completed professionally and with care, resulting in a beautiful pool deck that exceeded my expectations. What impressed me most was how clean and organized the crew kept the work area throughout the job. Junior and his team were always professional, respectful, and easy to work with. If you're looking for a contractor who takes pride in their work, delivers quality craftsmanship, and pays attention to the small details, J Lopez Construction is an excellent choice. I wouldn't hesitate to hire them again.
Junior and his crew did an excellent job on our deck project. The work included demolishing our old deck and building a beautiful new two-tier deck for our above-ground pool. From the start, Junior made the material purchasing process simple and straightforward, and his crew worked hard every day on site. His pricing was also very competitive compared to the other estimates we received. Most importantly, the finished deck came out great and was clearly built the right way using solid construction practices and attention to detail. Communication could occasionally be challenging due to language barriers, but overall we were very satisfied with the experience and extremely happy with the final product. I would definitely recommend Junior and his team.
El mejor gracias 🙏🏻👏🏻👏🏻👏🏻
Very unprofessional service. I scheduled three different appointments to meet at my house, and each time I waited with no one showing up. I lost about 4 hours waiting for Junior Lopez, who never arrived. I called multiple times and my calls were not answered. This was a complete waste of my time and showed a lack of respect for the customer. I do not recommend this company.
