"Herman Construction is the best company that I have hired. Karol and his crew work diligently, precisely, accurately, and are punctual. The quotes and estimates are accurate and fair. The work performed was professional and immaculate. Karol and his crew came in to install laminate flooring as I was about to start moving in. The flooring in three rooms came out gorgeous. I approached Karol with a plea of help. I explained the situation with the three rooms that had old carpeting. The previous tenants had dogs that destroyed the carpets and closets. Karol came in with his crew and performed a miracle. The rooms look brand new and the closets refinished to a state where I have lots of room for my clothing. I highly recommend Herman Construction and will be using them for all of my projects. They deserve 10 stars for being the best company."

Diane was our main choice, she knew exactly how to invasion perfect layout of our bathroom remodel. They set up a group chat with everyone to coordinate and they communicated very well. Inspections were schedule very quickly, and they forwarded us the results & paperwork as soon as they received it. Alex, the designer, was helpful in helping to putt together our design and vendor recommendations.

"We were looking to remodel our kitchen or bath for a few years. We kept getting estimates from different companies and always felt the price was off or the person was not a good fit. Then, finally, we met Shai with Cal Green Remodeling. What a great guy! He is very upfront and honest about what we can expect in terms of cost and work flow. Because of his honest approach, we hired him. We felt he gave us the good and bad and how to resolve the bad as well. In the end, the process was fairly smooth, and the few hick-ups we had, for example, the city and their permit process, were well explained to us at the beginning, so we were ready. Our kitchen or bath looks amazing, and I plan to work with Cal Green Remodeling again. Thanks Shai!"

Family owned business with over 22 years of experience -Remodeling - General - Remodeling - Kitchen & Bathroom - full home remodels - room additions - ADU's - Full Roof replacement -

"Would not recommend them to anyone. We had the worst experience with these guys. Scope of project: kitchen complete remodel, replacing carpet flooring with vinyl tile flooring , redo electrical for kitchen area only cost: 100K+ what went to plan: - kitchen demo - made one nice dry wall - setting up and framing of the kitchen area what went wrong: - communication/scheduling : we would never be told ahead of time when work was being done. Sometimes there would be days stretches where no one showed up and then guys would show up randomly on a Sunday morning. At the start of the project we told them we were going to move into the back half of the house, so just have that clean. We moved into trash and debris everywhere. They also saw a vinyl strap , strapped to our tree, tied to our neighbor's fence (it was there keeping the fence up as the tree was leaning into the neighbors fence). In their brilliance, they decided to cut the strap and use it for themselves. How did we know? we found it on our roof, used to tie some electrical conduit. Who the heck does that?! We should've cut ties at that point, it was just the start...if we only knew. But we gave them the benefit of the doubt...but things kept going wrong. - Kitchen cabinet install was not leveled, we end up telling them to not bother coming back and we installed the whole kitchen ourselves (re-leveling the base cabinets, putting on the hardware, installing the cabinet doors. - broke several custom panels (to their credit, they did pay for the reorder) but we ended up installing it ourselves , which we were never offered refund the labor. - the kitchen counter was not leveled, we also had to redo it ourselves in order for the independent countertop guys to install it. - cut hole for electrical switch too big, huge gap now in our org Eichler panel that is not repairable unless we replace the whole wall. - cut hole in wood beam ceiling too big for ceiling vent even though they had the manufacturer's specifications. tried to fix it, but it looks terrible. - lied and said they had experience installing lux vinyl tile. They didn't. The flooring , which is supposed to be new, looks like flooring that has been there for years and hadn't been replaced. It was discolored, uneven, not leveled, and not even lined up. How can you mess up lining up squares? Our sales person Joe ,came and made excuses after excuses , telling us " no one can install it better than them" , that this is the "best" we'll get. I cannot believe he could look us in the face and say that. We ended up requesting 1500 back, though for us to reorder redo the tiles for the kitchen will be 3K+. - as a last F you to us, they gave us the bill for the permit fees which includes a 3% of project cost recycling deposit that is 100% refundable if they just do the paperwork and let the city know where they recycled the demolition material. Our kitchen project was 80K and so it was $2400. Guess what, they "never heard of this" and have no proof of where they recycled the material and so cannot get the refund. I have no idea where they dumped the material.....and we're out 2400. The best thing about this project is finishing and NEVER having to deal with them again."

FAQs for second story addition building service projects in Cupertino, 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.
