Over 20 years in the business I install nearly all staircases. Curved stairs and spirals, iron and wood railings, deck railings and exterior stairs. As the owner operator I install all the work myself, except the painting and finishing for which I have someone I can recommend. Customer satisfaction is number one and I go out of my way to achieve this. Free initial consultation at your home or if you prefer at my shop in Mountain View. Very high quality work a affordable prices

"The full remodeling of my new house wouldn’t be possible wo Enrique. He built up my deck to backyard, which looks gorgeous with beautiful LED lights with affordable materials. Frontyard porch and side path are converted to fabulous walkway. Most of all, my crawl space has water flooding issue with winter rains, which many contractors said difficult to handle. But Enrique and Team did a great job with water pump and side ground works and i had no issue last winter. I would love to work with him again, definitely."

"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 Union City, 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.
