Very high quality work a affordable prices

"From start to finish, Enrique was professional, knowledgeable, and easy to work with. I've never felt better about investing in my home. Our front porch steps were severely in need of repair. The flagstone was falling off the frame and became a hazard for our family and others visiting our home. We had struggled to find others who could meet our budget or were comfortable taking the job. However, Enrique assured us this was well within his skill and experience and that we would be happy with the results. He could not have been more right! Enrique removed the old flagstone, added additional support for the existing frame, and installed beautiful new steps using Trex decking material. He even included exterior lighting! We are thrilled with our new stairs, and his work gives us great confidence in working again with MTZ Modern Carpentry. Thanks again, Enrique!"

Hi, I'm Joe. I'm the General Contractor of the Z7Team. I run my own crew of dependable, loyal workers who love what they do. There's no salesmen, no middleman. Just the crew & I.

I'm hands-on, and come to the job site almost daily to ensure your project is going according to plan. Schedule an appointment today for a free quote!

"My wife and I worked with Joe to renovate our home in the South Bay. We basically tore everything down to the studs and did some reconfiguring of the interior, as well as redoing all plumbing and electrical. With Joe and his team, we transformed a home that hasn’t been renovated since the 60’s to the home of our dreams. We were referred to Joe by a trusted friend, and after a phone call with an overview of what our plans were, we met Joe in person at our home for an initial walkthrough. Both my wife and I were impressed with how thorough he was with details regarding the renovation; it was immediately obvious he was a master of his craft, with a vast amount of experience and knowledge in construction. More importantly, he’s down to earth and honest; his transparency was very much appreciated. Joe and his crew take pride in their work. He’d go above and beyond by suggesting certain looks or practical modifications to our original request; it often felt like he was renovating for himself! For the project, he provided a clearly marked timeline and walked us through all the options for both finished and unfinished materials. His encyclopedic knowledge of stores in the Bay Area saved us a lot of money, and we got exactly what we wanted to build our home with! Home renovation is never a easily forecasted task; there are many surprises or issues that come up. With Joe, we knew we were in good hands. When a challenge did come up, he made sure to explain the options to us and address it immediately. Communication is key in this process, and Joe excels at it - he’s very responsive by phone and text. His crew is polite and also share Joe’s willingness to educate and explain the process. All in all, we felt that Joe became a family friend in the construction business and have recommended him to multiple friends and family. If you are looking for top quality work, reasonable pricing, and a trustworthy expert, look no further than Joe Arielli and his team!"

FAQs for second story addition building service projects in Mountain View, CA

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
