Carlos and his amazing team did a full remodel of our backyard including installation of a pool, deck, pergola, outdoor kitchen, fencing, retaining wall and more. It was our dream that we planned for a few years and Carlos and his team did an amazing job. I couldn't give Carlos and his team higher praises. They were incredibly professional, meticulous and even months after our project has been completed have made themselves available to help with any questions or concerns or fix any small detail that we can come up with.

QS Construction did a fantastic job on our landscaping remodel, including pool, outdoor kitchen, shade structures, perimeter fence, irrigation, and hard & soft scape. Carlos and his construction and landscaping crews were great to work with and were very timely and responsive to all aspects of the job. Attention to detail and finishing quality was top notch, and they were also very flexible in working with us to refine the scope and details of the project along the way, since we were doing a considerable amount of the design plans along the way. Would absolutely call on them again in the future, and highly recommend anyone looking for quality landscaping and contruction work.Read More

Carlos and his team have been a joy to work with. They are responsive, professional, knowledgeable, timely and easygoing, all qualities I look for in a contractor and I highly recommend. They did a full build for us, from dirt to completed pool, fire pits, turf, bbq, bar, driveway and landscaping, all within schedule. Carlos was very responsive to any changes and additions we had during the build, and had a lot of good insight and ideas. Build quality was excellent and all of his team members are friendly, respectful and professional. We even hired them to do our weekly maintenance. It’s been a few years since we completed the project and we’re very thankful we choice QS Construction...Read More

We have completed two major projects with QS Construction. Both our back and front yards have been completely renovated and updated. This includes pool resurfacing and all new controls, beautiful hardscape and landscape - as well as electrical, lighting and touch pad controls. We couldn't be more satisfied! Carlos Ronquillo and his highly skilled staff designed and implemented both projects from inception to completion on time and on budget! I highly recommend QS Construction!
