RG Construction
RG Construction
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."
