**★★★★★ — Aurelia, Sept. 2025**

> Carlos and his team are very responsible! They listen to my needs and gave very knowledgeable recommendations and suggestions. He finished within the time frame he promised and dealt with the city for permits and inspections in a professional manner. Would definitely work with them again.

**★★★★★ — shellgar, Sept. 2025**

> Carlos and his team did an amazing job with our front and back yard remodel! Carlos is super responsive too! We are so happy with the end result!

**★★★★★ — John Austria, Sept. 2025**

> Carlos and his team did an AMAZING job with our landscaping project.  He is very experienced and has a very detailed eye which helped us stay ahead of potential project issues.  We appreciated that he kept an organized and clean worksite.  His crews cleaned up daily and Carlos effectively mitigated any construction impacts on our neighbors.  All the work was delivered on time, to budget, and with a very high quality standard and finish.  Carlos communicated with us frequently, escalated issues quickly, and did his best to keep our project on schedule.  Carlos is one of the best contractors we have ever worked with. We highly recommend Carlos and QS Construction!

**★★★★★ — minaroades32, Jan. 2024**

> I cannot recommend QS Landscape enough. They are very professional and knowledgeable. They take the time to perfect your design. This is a rare quality in a contractor. Excellent product. Gorgeous landscape construction.

**★★★★★ — Nathan Phail-Liff, Jan. 2024**

> 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.

**★★★★★ — Chris Tan, Dec. 2023**

> 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.  Everything is holding up great and Carlos is always easy to get a hold of whenever we have issues or new additions.  Among the best contractors we’ve worked with and our go to for any outdoor project.

**★★★★★ — HU-29947303, Dec. 2023**

> 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!

**★★★★★ — Debbie Stacknick, Oct. 2023**

> 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.  I've heard horror stories from many friends doing backyard renovations and I can honestly say that we had no issues.  I would highly recommend Carlos and QS Construction for any exterior construction and landscaping needs.
