Client Testimonies

I am very satisfied with the work Southwest International Builders LLC has provided for me in the construction of my warehouse MAS Melons & Grapes. I strongly recommend Southwest International Builders LLC as a contractor and engineer.

Raul Martinez is a phenomenal builder in every sense of the word.

He built a wonderful home in Rio Rico that our family was very fortunate to purchase. It’s not only beautiful, but well designed with very high quality materials, finishes, and appliances. We were first time homebuyers, and Raul was a great resource for us during the buying process and long afterward. His professionalism and knowledge of the construction process was evident throughout every facet of this house.

We consider him a friend now, and we’re lucky that he is our neighbor.

Raul Martinez came highly recommended to me by a colleague to assist with the building site and structural engineering of my home. The site was particularly challenging due to its topographical layout and strict HOA building guidelines, but Raul provided innovative solutions that got my dream home started.

After seeing his excellent work, I hired Raul as the general contractor and builder. His dedication, skill, and professionalism have exceeded my expectations. He handled everything from finding contractors and subcontractors to providing competitive pricing for each phase of the project. Raul has managed the construction for over a year, resolving issues promptly and even navigating HOA concerns smoothly. I couldn’t be happier with his leadership and the progress of the project.

Over the past year, I have had the pleasure of working with Raul Martinez and Southwest International Builders on the construction of a large residential retaining wall. The scope of the project was complicated, due to an existing non-compliant wall and steep fall-off into a wash.

Despite the difficulties of the terrain and location of the home, the work proceeded with care and respect for the property and neighborhood. Raul’s attention to detail, follow-through, and the team's strong work ethic and expertise produced a successful outcome. Mr. Martinez and his team were approachable and positive and delivered high-quality results.
