"Review from perspective of first time home owner/buyer who had a long list of projects and home improvements that required a general contractor. I recently purchased a two bedroom home in Mill Valley and after moving in quickly realized that there were a littany of projects that needed to be completed in order to make my new home more comfortable and presentable. I received 3 referrals for different general contractors from friends/family and went on the meet and receive estimates from them. I decided to go with Fred and FSP general contractors for my initial set of priority projects based on my favorable impression of Fred, his fair and straightforward estimates, and clear communication of timelines to both start and complete the initial projects. I decided to continue to work with Fred/FSP for my 2nd/3rd traunch of projects based the high quality of work performed during my first set of projects, adherence to estimates and timelines, and ease of communication during the process. In particular, I appreciated Fred's flexibility with my evolving priorities and his availability to meet/speak/text about questions and/or recomendation pertaining to ongoing work. The work that Fred/FSP did and continues to do for me was diverse but probably representative of the type of work many people are interested in: 1. Remodling of bathroom including istallation of new fixtures and replacement of original tile. 2. A tricky and unusual rebuild of a fireplace and mantle. 3. A custom designed/made concealed wiring scheme for tv mounted over the new fireplace mantle. 4. Replacemant and installation of lighting throughout house. 5. A full review, recomendation (s), and upgrades for electrical integrity of the entrie house. 6. A long list of random tings I thought of along the way! I feel fortunate to have crossed paths with Fred/FSP and will continue to work with them for all home improvement projects moving forward. I highly recommend this company based on the honesty/integrity of Fred and his crew, the adherence to reasonable estimates and timelines, and the high quality of all work performed."

Customers say: True professional

"Matt, Eric and team were great! they were here when they said they'd be here. Matt checked in almost every day even if he wasn't personally on the build that day. They had a "customer is always right" mentality and didn't penny pinch on change orders. Half way through the job Matt realized that the natural gas fire insert installation was more complex than his team's skills. He immediately sourced a specialized contractor to do that part of the job which gave us all a tremendous amount of confidence. The attention to detail was great and nothing was too big or too small to discuss. We are extremely satisfied with the end product. It looks great!"

"I found these company online and I hired them to replace all the existing windows and patio doors with new fiberglass (Milgard) Ultra windows and a double French door from them a few months ago for our renovation. They provided us with an awesome price for the windows and doors themselves and for the labor of the installation as well. The representative that I spoke to was very professional and he came over to my house on the time and day that was scheduled ahead of time via the office. The people that we were involved with (including the installers and the sales man), was definitely outstanding. We had a minor issues that accorded during install, and they provided awesome post-sale support as well. I recommended them to all my friends and family as a great company for any energy efficient products. They are fantastic. And have some Sunday hours, which is absolutely a great help. We purchased 2 additional exterior doors from them and this was an add on that we decided to do in the last minute and after the work was stated. We were sure that they won’t be able to do it during the same time… but they did it and it went so smooth and excellent. Should've gone to Landmark construction energy crew for those too. You can shop with confidence with them!"

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Our bathroom was outdated and cramped, so we decided to remodel with Ocean Seven Builders. Ron was involved throughout the process and made sure we understood each step. What stood out most was how organized everything felt once the work began. The team was respectful of our home and finished the project close to the expected timeline. The final result looks modern and much more functional!"

"I went with Expert Home Builders on a room addition. The big and expensive project and bog responsibility but I'm happy I hired this contractor. David and his team showed up on time and they were great from first day to end of this project. David was knowledgeable, honest and helpful. He informed me about working progress all the time and contacted me immediately if there was something important. His team worked hard, kept working area clean as possible, they were professional, friendly and quick also. The project was finished ahead of schedule and results are excellent. The quality of work is superb, overall experience excellent and price very acceptable. I would highly recommend Expert Home Builders to all people I know!"

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