"LECUT CONSTRUCTION did a marvelous remodeling of my kitchen and bathroom. I wanted my 1970s style condominium to look and be more modern. The contractor was attentive and considerate of my needs and walked me through the process and what would happen. Guy recognized that this was an experience I had never gone through before, and gave me assurance that I was a part of the team. He provided me with a designer that looked at my budget and the ideas I liked from the internet, and we came up with a great plan. The results are beautiful and although being out of my place for the time it took was stressful, it was all part of the expected process and was worth it. I have received so many compliments from friends and family, and I highly recommend LECUT Construction if you are looking to renovate your kitchen and/or bathroom."

For the past 10 years GAXL has gained a reputation as a well trusted general construction company in the Bay Area. We depart from the idea that our clients deserve the best remodeling experience. The main focus for us is finishing the work right the first time and on-time, always within budget. At GAXL General Construction we are aiming to be a company leader in the market in Northern California in which our clients can trust with 100% confidence their construction/ remodeling needs. We strive to be consistent as well as efficient in the delivery of our services, and offer our clients a one-stop source for their construction and remodeling needs. Once again, thank you!, we are looking forward to speaking with you about your next project; big or small, we are here for you! How about that new deck or gazebo? Are you ready for those family gatherings? Want to turn your backyard into your new summer/fall hang out spot? We will make sure we bring you creative solutions done perfectly right with the help of our experts. Let's talk today! -Building with Vision.

"We received quotes from 3 different contractors. We chose GAXL because it's close to Newark and I like how Jose explains everything in detail. Originally we thought the remodeling would take 4 weeks but it took close 6 weeks. The whole project was great, the craftsmanship was superb. At one point, we found some tiles that are not very nice (from the manufacturer) and we asked them to redo the bathroom wall. They don't complain and understand our request. The workers are great, especially Marvin and this other guy (forgot his name). They WORK very very hard from 8a to 6p everyday. Jose is on time and is very prompt in returning calls or text. In fact he's the only contractor who's very prompt and I like that! On one of the walls they discovered a mold due to rain leaking and they're able to fix it in 4 days which is great. Jose and his son pickup the materials from the suppliers and drop them in our house. Overall, Jose and his men are courteous. I will definitely use GAXL for future remodeling."

"Oscar truly stands out as a contractor who cares deeply about his clients, and that’s exactly how he made me feel. I reached out to five different contractors to assess my bathroom and offer ideas, but my experiences varied significantly. Some were overly sales-driven, others dismissed my ideas entirely, and one didn’t even follow up with an estimate. Oscar, however, was a breath of fresh air. He arrived on time, listened attentively to my ideas, and offered thoughtful suggestions. He was highly collaborative with the other workers on site, making sure everything was well coordinated. Oscar's expertise in the industry is evident, and he’s exceptionally creative when it comes to problem-solving. When he identified additional challenges during the project, he took the time to offer practical solutions, demonstrating his commitment to delivering the best result. Oscar has earned my trust and will be my go-to contractor for any future projects. I highly recommend him to anyone in need of a reliable, skilled, and dedicated professional"

"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."

"Excellent! I thought I needed a new thermostat since I wasn’t getting any heat. Juan came over , checked the circuit breaker and found that the breaker was worn out. He replaced the breaker and found that the thermostat was still functioning. He could have said that the thermostat needed replacing too but instead he just said you needed a new circuit breaker. I really appreciated the honesty. If he said I needed the thermostat too I would have paid for both thus increasing my bill. I just want to add a few more comments about the work that he’s done for me. I first met Juan when he came over to my house to stabilize a lose tile that was above my garage door. Then I showed him mold growing next to my shower door. He found a small crack that allowed water to seep into the sheet rock. He replaced the shower door and the sheet rock that was growing mold. Then I took him to the bathroom where I showed him a bulging floor board next to the toilet. He found a small crack in the toilet tank that slowly dripped water on to the backside of toilet dripping water onto the base board. He offered to repair the tank but I told him to go ahead and replace the toilet. I can’t say enough about Juan. Whatever the problem is he’ll figure out how to fix it. When he approaches a problem he approaches with a positive attitude. Another time my ceiling fan went out and I asked him to come out to see what the problem was. Instead over the phone he told me to check the remote control. I went on Amazon and ordered a new remote control . I placed in new batteries and the fan started working. He didn’t charge me anything for the advice. I was prepared to buy a new fan and all I needed was a new remote. Juan is multi talented. I’ve recommend him to my neighbor and he’s done a couple of projects for her (leaking roof). Lastly, in a couple of weeks he’s coming over to paint my front door and put a new latch on my side gate. I’m 77 years with an injured leg so fixing things around the house is difficult for me. Juan has made my life easier."

FAQs for addition to existing structure building service projects in Livermore, 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.
