"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!"

FAQs for second story addition building service projects in San Jose, 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.
