"Excellent, no problems. My car was new the first year I used the service and there has never been any damage during the transports. The men picking up and delivering the car have always been pleasant and cooperative. Both Ely and Guy at United Transport has been highly responsive to my needs. I would highly recommend this company."

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."

Founded in 1989 by Dean Henninger, D.W. Henninger Construction has been recognized as a leading builder of custom homes and remodeling projects. Acting as a General Contractor, the entire Henninger team is known to exceed client expectations, leading to a steady stream of testimonials and referral clients.\n\nOver the past two decades, Henninger has managed projects in California: kitchens, bathrooms, room additions, entire home renovation, even complete construction of homes. Regardless of scope, Henninger approaches each project with the same foundation of principals: strong design aesthetics, comprehensive product options, sound project management, and a commitment to craftsmanship.\n\nDesign Aesthetics: With 20+ years of Bay Area experience, Henninger understands the many architectural quirks unique to Bay Area communities, making it easy to elaborate and integrate with established design aesthetics.\nProduct Options: Henninger is truly unique in being a single-source stop for design, remodeling, and product resources. Cabinetry, countertops, appliances, and plumbing fixtures are all available options for your project, and Henninger assists with selection, delivery, even vendor communication if there’s a problem.\nProject Management: Project management is essential to delivering a good customer experience. Henninger prioritizes project management to the same degree as design and crafting. Henninger is unique in using progress billing — a system that only charges for services following completion rather than pre-paying weeks or months before it starts.\nCraftsmanship: Henninger’s team of carpenters bring the best combination of experience and expertise to the table, but they offer much more than technical proficiency — by working with true craftsmen, Henninger projects balance design and functionality for maximum results on each and every project, regardless of scope.\nOur service areas: Oakland, Pleasanton, Livermore, Walnut Creek, Fremont, and surrounding cities. Projects in San Francisco and San Jose are also feasible — contact us for more information.

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.
