"Excellent experience. The price was fair, Ofer was very flexible and responsive to what we needed, and his team were punctual, professional, and efficient. When other contractors would take days to respond and provide estimates, Ofer always got back to me in a couple of hours at most. Adding the skylight took only two days, and the only additional cost was for the skylight itself (about 200$) and paint (about 40$)."

"I have a beautiful master bathroom, thanks to Ruben Olivo, and the process was so smooth! Ruben does quality work, pays phenomenal attention to detail, and is a master of all trades: tile, plumbing, electrical, etc. Our remodel was completed on budget and according to schedule. It was relaxing to work with just one main person: no subs, no stress! You’ll notice Ruben’s professionalism and helpful, calm demeanor immediately and value his work ethic and enjoyable personality as he works at your home. We were nervous to select the right contractor for our first project and now we’re already saving to team up with him for another!"

"It can be really difficult to find the right contractor, one who is honest, shows up on time and does quality work at realistic prices. I found them in Bielefield Construction! This company has a great crew with many talents. Ray built us a dream deck that will last at least two life times. Thank you Bielefield Construction and crew."

"John sent Ross right away to put an emergency shower repair. The job was done quickly and very clean. I am very happy with the outcome with Bay Builders Inc. After 3 years the repair has held up very well."

"When I hired Brian I was out of town and unable to work on the project myself. I hired Brian over the phone, and he was able to assess my needs for the repair. He gave me a bid I was able to complete the job that we set out to complete. He met the price range that he gave in the bid. And the great thing was is we were able to do it over the phone without any difficulties. His knowledge base was strong, so we did not have any hiccups or difficulties during the construction process. I would recommend Review Concept Design and Development inc. as a quality construction organization."

"Marc was excellent at communication through out the whole project. He made sure everything met our expectations and he went above and beyond to follow up on anything that we had a concern about. We had two bathrooms that he remodeled for us and he never once left us with out running water or electricity and always made sure we know what was going to be worked on each day and would check back in with us before leaving the worksite for the night. 10 Star service, I am sure if we had asked he would have a rolled out a red carpet for us. It was by far the best experience we could have asked for."

"First String Home Improvement Company installed my bathroom door, and the results exceeded my expectations. I’m very picky when it comes to details, but with Skyler I didn’t have to supervise him at all—his professionalism and expertise were evident throughout the entire process. On top of that, he’s incredibly enthusiastic about what he does, which made the experience even better. This company is my go-to, and I’ll def hire them again!"

FAQs for addition to existing structure building service projects in Rohnert Park, 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.
