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."

We have been in the construction industry for over 10 years. From building ADUs, high-end kitchen remodels, bathroom remodels and home extensions, we have done just about everything under general construction. Our company prioritizes safety, quality and transparency.

"Me and my wife decided recently to get our kitchen remolded. After some time searching for the right guys to do the job we settled on RG Construction. Richard, who is the owner, is a great guy and super informative. He never left any question unanswered or left us uncertain about anything. His crew works quick, and they pay attention to the tiniest detail. They absolutely are worth every dollar and I would recommend RG Construction to any homeowner, and I for sure will be giving them a call back for any work I need done in the future. Me and my wife are absolutely in love with our remodel."

"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need.

Percolation Tests questions, answered by experts

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

Regulations require certified professionals for removals and disposal in compliance with local and federal guidelines, ensuring safety and legality.

The Environmental Protection Agency (EPA) banned the use of asbestos pipe insulation in certain applications in 1975. It released further bans in 1989 and 2019. While asbestos pipe insulation was common from the 1930s to 1970s, its use fell off after the 1970s due to public concern and the EPA's actions.

If you hire a dedicated asbestos inspector near you in addition to your local home inspector, it will cost between $200 and $800. If, however, your general home inspector happens to be certified as an asbestos inspector, they can charge you a smaller fee and tack on the cost to the home inspection. In general, home inspectors do not do physical testing, but will provide a visual assessment so you know what you are working with.

Asbestos siding can be dangerous if disturbed because the material itself poses a health risk. Asbestos is one of the leading causes of lung cancer as it causes mesothelioma—an aggressive cancer. Asbestos can also cause irreversible damage to your lungs by creating a buildup of scar tissue, called asbestosis. It has a habit of making its way through even robust personal protective equipment (PPE), which is why it’s not recommended that you perform any asbestos work yourself.
