We have been wanting to expand and enclose our patio for years, but it is so hard to find RELIABLE and RESPONSIVE people to do the job.We met Jose with MTZ Builds through a referral of a friend and right off the bat knew that this was the company that would see this project through. He replied to my initial message and arranged to come by to discuss job within a day or so. His crew was able to start the job on time and even with an entire week of drizzling rain, was able to complete the job in a timely manner.We did have a few issues with some of the work performed by subcontractors, but I was able to reach Jose. No excuses. He agreed that the work did not reflect the standards of MTZ Builds and he made sure it was done correctly!We couldn’t be happier with our outdoor living space! It has completely transformed the area and our ability to entertain guests!

Jose and his team were amazing when replacing my roof on my first home purchase. He was quick, very knowledgeable, and thorough in his work. I plan to use his company for all of my contracting needs going forward. Very happy with MTZ Builds.
We are so pleased with our new porch and patio! Jose and his team have been great to work with, very responsive, so polite and the workmanship is top notch. Highly recommend!

MTZ Builds is a quality company. I hired Jose and his crew to remove an old outdated patio deck and replace it with a new screened in deck. The new deck is “awesome”, quality craftsmanship, stylish design, and a beautiful addition to my home. They also removed and replaced a set of old concrete steps leading to the front porch and replaced them with wooden steps to match the new deck. A job well done, thanks Jose!

MTZ is top notch!!!! They turned our 1970’s bathroom into a beautiful walk-in shower. They always did exactly what they said they would do and when they said they would do it. I look forward to our next project with them.

Jose and his team did a fantastic job for my patio cover. I told him what I wanted and just let him go for it. Already had friends over and they love it. Very easy to work with and hope one day we can do business again.

I contacted several contractors and MTZ was the only one who responded in a timely manner. Jose was professional, understanding of our budget and needs, and very knowledgeable. We feel comfortable having him move forward with several large home projects and will definitely be updating our reviews as the work progresses! I’ve no doubt we will be using MTZ for several home projects and recommending them to everyone we know!
