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’re a family business: Sami, Pini and their sons are the core of Sami and Sons. When you work with us you’re treated like family. We value our customer’s time, needs, and opinions. We want to build beautiful things together and help your home fit your needs. We bring Silicon Valley to building: Whether we are remodeling your kitchen or building you a new home we have all the tools needed to make the process seamless. From 3-D designs to VR (virtual reality) walk-throughs you will know exactly how your project will look at completion. We are here for you every step: You will be taken care of and in touch with your own personal project manager that is assigned to you and your project. We are there for every development and every question. You’re family, we’ll take care of you. Our customers love us: And we love them too. Check out our Houzz, Yelp, and Facebook!

"We chose Sami and Sons over 3 other contractors we interviewed with to remodel our bathroom, and we couldn't be happier. After meeting with Abel and Sami himself we discussed a very reasonable cost estimate for the work that needed to be done. Abel even took us out shopping to several tile and home improvement stores to fan our imaginations of what could be possible for our new bathroom. Throughout the entire process the staff from their front office to their onsite project manager Paul were always very responsive and helpful. This was our first major remodel and laborers were very knowledgeable about creating the bathroom we wanted to achieve while keeping up to date with building codes and city permits. Mario and Erick always asked us questions on how we wanted details in the bathroom to turn out. Always gave us suggestions when we were clueless, and always advised us properly when choosing fixtures and other materials for the build. It was very helpful and reassuring that the managers used the BuilderTrend scheduling app so we knew what tasks were to be completed and on what days so my wife and I could plan things ahead of time. There was a miscommunication about the work at one point, but once we were able to talk to the project manager and other managers on the job they were able to resolve the issue very quickly and to our satisfaction. Scheduling work per day could've been more efficient, but overall we loved the results and our bathroom turned out exactly the way we envisioned and we've been loving it ever since it's completion. Thanks again Sami and Sons for making our dream come true."

Percolation Tests questions, answered by experts

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

You shouldn’t see a difference in your home’s value from your local property assessor if you have asbestos. Does asbestos affect home value when you are selling the home, though? If you are planning to sell the home, most jurisdictions require you to legally disclose the presence of asbestos to any buyer. Most buyers would have reservations about purchasing a home with asbestos, so they may offer less for the home. If you hire a pro to completely remove the asbestos, you do not have to disclose to buyers that the home once had asbestos.

Since DIY asbestos removal isn’t the best option to save money, there are other steps that you can take to help cut costs when dealing with this project. After speaking with your asbestos removal expert, discuss if encapsulation is an option. If it is, you can save between 15% to 25% on overall project costs over demolition and disposal. In addition, when speaking with your professional, discuss if there are any tax credits available for your removal project. Finally, check with your homeowner’s insurance to see if any removal costs might be covered. However, be aware that this is usually only applicable if the asbestos is due to a covered incident, like a tree falling into your roof.  

In the 1980s, the use of asbestos in house siding materials underwent a significant decline, ultimately being phased out by the mid-1980s to early 1990s. This change was largely due to a growing awareness of the severe health risks associated with asbestos exposure, particularly its link to lung diseases and cancers. With increased public concern and regulatory agency involvement, building codes and regulations were updated to restrict the use of asbestos in construction materials. 

When asbestos fibers become airborne, they enter a person's respiratory system. These fibers scar and damage the lungs and often lead to serious cancers like mesothelioma. Like many dangers in the house, asbestos isn’t easy to see when it could be causing serious damage. The amount of time exposed, combined with the person’s tolerance for asbestos inhalation and the amount inhaled, will all contribute to health problems.
