Hello there! We are Guillermo and Shirley, a happily married couple with three decades of experience in the construction industry and proud co-founders of our successful construction business. With a shared passion for building and a strong work ethic, we have established a reputation for delivering high-quality projects on time and within budget.

Plan It

When it comes to planning for your home renovation, thoroughness is key. We always start by defining your goals and priorities for the project, whether it's updating the kitchen, creating a more open living space, or enhancing energy efficiency. Next, we will create a detailed budget that includes not only the cost of materials but also labor and any unforeseen expenses.

Build It

Once the action plan, budget, and timeline are established, our small but skillful team will begin the execution. What is so good about us? Our clients often say they are amazed by our attention to details and the creativity we pour into every project we take on.

Deliver It

We understand the importance of keeping our promises once they are made. We will always be straightforward and transparent with you about what is possible and what is nonnegotiable when it comes to your dream home. Everything we agree on at the beginning of the project will be delivered as they are.

Client Reviews

BRIAN LUGO

A string of bad experiences with contractors led me to essentially give up on my project. Guillermo was sent from heaven to save us, and he approached the work honestly, conscientiously, and as if it was his own home. I will never work with anyone else again.

Guillermo and Shirley took their time to explain the whole process and answered our questions. It was so easy working with them. Their team is super professional, and the best part is everything happened accordingly to the schedule we set from the start.

There are not enough positive words to describe GS Complete Builders. They are trustworthy, honest, and responsive. Guillermo transformed our poorly constructed and not-great-looking house into a beautiful home beyond our expectation. Not only is he an expert, his attention to detail is awe inspiring, and he treats your home as though it is his own. The entire team is filled with artists, mathematicians, and magicians. We are so grateful to have worked with GS Complete Builders – they’ve become like family.

Guillermo and his team performed a complete inside and outside renovation on our outdated home in less than 3 months. Guillermo expertly crafted our “forever home” with his creative ideas and attention to details. We are eternally grateful for the work and a new friendship.
