Work Description: Deck addition and remodel

Comments: I recently had a luxury composite deck installed with cable railing and aluminum post
by cosmo deck contractor.
I found Cosmo and their team honest, committed, and on-time deck builder contractors in the area and I couldn't be happier with the experience and the result. From the very beginning, the team was professional and knowledgeable, offering expert pieces of advice on deck foundation, expansion, pulling permits process from the county, and the best different materials combinations and design options They worked with me every step of the way to ensure that the design was exactly what I wanted, and the materials used were of the highest quality from trex product and muzata cable railing product.
The installation process was quick and efficient, with a focus on quality and attention to detail. The final result is stunning, with a high-end look and feel that has already added significant value to my home. I highly recommend cosmo deck company to anyone looking for top-quality composite decks, custom design, and installation services. Thank you for the outstanding work!" Best luck Mohib😂
