"My husband and I are so happy with the work they did. Our front porch looks great. I also hired them to fix a wall of our rooftop deck. I have recommended Justin to a neighbor and he will be working on his house soon."

"Our experience is identical to what other reviewers shared. And yes, you should run from this company as fast as you can. Do not buy what Abraham shared that the payment must be made when the inspection is passed. Check the Business and Professions code yourself, the payment only needs to be made when the job is completed. It is very COMMON that the job is not even done or poorly performed even the inspection is passed. Here are the issues that multiple families including us run into with this company:: The project was delayed for over 9 months. No one manages the job. He often employs young men from his own Jewish community. They are enthusiastic but had no prior experience. The worse part is that they don't get paid. Two of them even set up a new construction business knowing Abraham will never pay them. Subcontractors can put your house on lien also. Many reviews you see on Yelp, Google, Angi are NOT genuine. Even the references are fake with hindsight, we were given 2 references. One reference shared the exact same accent as the PM. The other reference was initially happy with their work, but then reached out to us and shared a similar horror story with them like what we experienced. You will lose a lot of $$$ on materials as the subcontractors will somehow leave a thousand dollars worth of quartz at home. Maybe they want to compensate for the money Abraham owed them? Let me tell you, reordering materials is not fun."

FAQs for addition to existing structure building service projects in Santa Cruz, CA

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
