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 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."

"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 plumbing installation for a remodel or addition projects in San Lorenzo, CA

Adding bathroom plumbing to a detached garage starts with the basic line installation cost of $900 to $1,300. On top of this base expense, you'll need to budget for each fixture. A toilet costs  $250 to $550, sinks cost $150 to $800, and a shower or bathtub costs $400 to $1,900. The project will also require ventilation, moisture-resistant materials, and possibly electrical work. Remember that these costs reflect only the plumbing aspects—additional construction, finishing, and permitting expenses will apply to complete a functional bathroom space.

While certain aspects of garage renovation might be suitable for DIY enthusiasts, plumbing installation requires professional expertise. Connecting to water and sewer systems demands specialized knowledge and equipment, and improper installation can result in severe water damage, code violations, and potential health hazards. Most municipalities require permits for plumbing modifications, and these often stipulate that licensed professionals must perform work. Consider limiting your involvement to simpler tasks like painting or basic finishing work.

The timeframe for adding plumbing to a detached garage spans one to three days for the actual plumbing work. However, this represents only the active installation period. The complete project timeline must account for planning, obtaining permits (which can take weeks depending on your locality), coordinating multiple contractors if needed, and addressing any unexpected challenges that arise during installation. Weather conditions can also impact excavation and outdoor connection work.

Adding plumbing to a detached garage will likely increase your property taxes. Tax assessors consider plumbing an improvement that enhances property value and functionality. The specific tax impact varies by location and project scope. Converting a garage into living space with plumbing facilities can trigger significant reassessment in many jurisdictions. Before proceeding with your project, consult your local tax assessor's office to understand the potential tax implications and factor this ongoing expense into your decision-making process.
