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 repair all types of damage, such as cracks, seam separations, chips and can refinish (remove scratches) & modify SOLID SURFACE (Corian, HiMacs, Livingstone, Staron, Wilsonart, & more). We also can repair cracks, nicks, seam splits & sink replacements in STONE countertops (Granite, Marble, Quartz, etc.) We can remove & replace sinks in both SOLIDS SURFACE & STONE TOPS including modifications to the countertop. WE WORK HARD TO BRING EVERY CUSTOMER A SUPERIOR RESOLUTION TO THEIR NEED. Our main office is in Central California so we cover from the greater Sacramento area to Fresno, the Bay Area to the foothills. We also have technicians who cover Northern & Central Oregon & Western Washington up and down I-5.

"Mediocre service and absolutely appalling customer service. Before having our granite countertops cleaned and sealed, I specifically mentioned how I had used acetone to treat certain olive oil stains and deliberately asked whether or not this would affect the cleaning and sealing process. Their technician assured me that it would not. After one hour of work, I observed that many of the areas that I had previously treated with acetone were significantly darker than other areas of our granite countertops. I am pretty sure this was due to the acetone-affected areas not having any prior sealant, so they absorbed water or cleaner or other liquids that were used during the cleaning. I asked the technician why certain areas on our granite countertops were much lighter than the darker areas. His response was ,I do not really have an answer for you. I found this answer unprofessional and unacceptable for someone who specializes in countertop repairs. As someone who is untrained and unskilled in countertop repair, even I could tell that my countertops had been cleaned and wetted by some cleaning agent and then sealed immediately without enough time for the cleaner to evaporate. The fact that I specifically asked beforehand over the phone whether or not acetone-treated areas would be affected by his cleaning and then immediately found darkening issues on these exact areas is an issue I cannot overlook. Furthermore, upon contacting Cole Restoration about my complaint, I was given a generic email response about how they want all of [their] customers to have a good experience and they asked for photos. I quickly replied with photos showing the areas of concern. This was over a month ago. Since then I have sent two follow up emails and left a voice message. Still ZERO response. All around dreadful, neglectful, and unacceptable. I can not and wont ever recommend Cole Restorations to anyone after being an afterthought to them for over a month."

Granite Countertop Companies questions, answered by experts

Engineered stone is known for its durability, lasting 15 to 20 years or longer. Of course, this range assumes high-quality materials and regular maintenance. After a couple of decades, the stone will start showing its age. Watch for discoloration, fading, stains, and burns, but it’s unlikely that engineered stone will experience structural failure.

A countertop contractor is the best person to install your quartz countertop. Because installing quartz countertops can be challenging, it’s important to consult a professional with experience installing quartz slabs to get the job done right. Repairing quartz countertops can be expensive, so it’s important to hire a professional to avoid damage.

There are many benefits of granite countertops, but it’s not unusual for them to have seams—especially if you’re working with small slabs joined together. Seams are common on larger islands where the installer needs to use more than one granite slab to cover the surface. Luckily, because seams are normal in granite countertops, pros know how to hide them properly, so you’d never know they were there.

Undermount sinks have clips that attach to the countertop, but they have pros and cons. They are heavier than drop-in sinks, so they only work with sturdy countertops like natural stone and are a more expensive option. You might need someone to help you install the sink, depending on its weight.

Stone can last anywhere from 15 to 100 years before it needs to be restored. You should clean your stone flooring or countertops regularly using cleaners designed for stone surfaces. Stay on top of vacuuming to prevent scratches from deteriorating stone faster, deep clean your stone surfaces using a pH-neutral cleaning solution at least once a year, and reseal the stone every one to five years, depending on foot traffic or usage.
