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."

"The employees were great. A couple of days there was only 1 man on the job due to illness. The company did not replace him, so the 1 man had to work alone, slowing down the completion of the project. Art and Johnny were great to work with. Communication with the office was a little lacking, but overall we are happy with the work."

"We could not be happier with the remodel of our dated, dysfunctional, tiny kitchen. Ruben was very professional, friendly and a real problem solver. He continually went above and beyond and we simply cannot say enough about what a great contractor he is. We had an unforeseen deadline and he and his staff worked very hard to make sure the job was finished. Their work was meticulous and the final result outstanding. Thank you Ruben and staff!"

"Jake is very friendly. In the end I felt over charged for the work done. It only took 4 hours for his hard worker, who only spoke Spanish, to do the job, Jake was gone95% of the time and didn’t return until the job was done. His estimate was significant for the end amount of work. He took some off the initial estimate after I brought up that it was instead of 2 workers only 1 and for 8 hours, which ended up being half. I was not thrilled. Job site cleanup charge for $250. there was no clean up. dirt all over my tile floor and dirt all over the ceiling attic cover that I had to then drag my ladder in to clean up. Materials charge for $600.? a few pieces of cheaper wood than the redwood the house was built with. a few screws? I’m sorry I am a senior as well. I honestly don’t feel this job should have cost 2k. I have owned 3 different homes, I will never go with 1 estimate again. Just being honest here."

FAQs for addition to existing structure building service projects in Guerneville, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
