"I had an amazing experience with Be home Remodeling, I want to thank Josh Zack's and his team of dedicated professionals for the amazing job they did on my master bathroom. Josh?s dedication and communication was crucial in ensuring the job was done quickly and professionally. He was is always available and provided quick response! We decided to do a bathroom remodel a couple of weeks ago. The entire process was done properly and as described to me at the start. Project was on schedule and went extremely smooth. The workers and staff were really professional, polite and easy to work with. I highly recommended BE Home Remodeling and specifically Josh Zack."

"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 highly recommend hiring Adrian Kovaci and his crew at Ceres Construction for your home construction project.The quality of their work was superb, the cost was comparible to the three other quotes I got from other companies, and their work presence at my home was unobtrusive as I could hope for. My two level 1923-built Richmond district home in San Francisco had a derelict passage to my garage - crumbling door, wobbly side stairs, and dry-rotted siding. Nothing was up to code. Adrian noted all the items that had to be reconstructed and said the project would take up to 20 days (it actually was finished in 18 days.) Adrian was very accommodating in giving extra finishing touches to my door hallway without extra charges, which I appreciated. I was concerned about the cost of the project and the disruption the work would cause, but Adrian's calm demeanor and the friendliness of the crew put my worries to rest. Thank you Adrian for leaving the work area spotless and for the quality work!"

"Prosper and the team at Prosper Construction just completed a beautiful renovation of my home. I badly needed new flooring and decided to add other updates as well. So we embarked on the journey to design an addition to our home and redesign the entire front of the house, which included a kitchen remodel as well. I knew that I wanted to replace my carpet with porcelain tile, but I thought that I would leave my existing kitchen tile in place, to save a little money. Prosper convinced me to eliminate all transitions in the flooring and replace the entire house with the new tile, and I am really glad that he did! The house now has a smooth flow and an expansive look that is just gorgeous. The entire experience was beyond worth the investment. The most amazing part of the transformation of my home is my stunning new master bathroom, which Prosper also advised me on."

"It was a pleasure to work with Eric, we hired him for a complete backyard renovation which included tree removal, leveling the surface and place pavers and a deck on top. Also built a retaining wall. The work came out very nice in part because of the great design ideas that Eric gave us. The project ran into some unexpected issues that Eric was able to overcome nicely. We were impressed how Eric handled the project and met all the deliverables, also his team was extremely polite an professional. Our backyard now looks like the ones advertised in magazines. All this led us to start a new project with him to replace the cracked driveway with nice new pavers."

"We found McCormick home builders through Angie’s list. They were not one of our original contacts, but they contacted us and came out to give us a quote. Matteo was extremely helpful, informative, honest, and gave us reasonable realistic prices, and did not try to inflate the prices or pressure us in anyway. We felt very comfortable with him immediately. We felt like he was a member of the family that we could just talk to and ask questions he was very personable. He gave us his contact number in case we had other questions and he was always available when we needed him for any type of questions or concerns. Mateo‘s team did a beautiful job. They were fast. They were efficient. They cleaned up beautifully. They did a wonderful job. They were very considerate of our time our needs and our neighbors. They were an absolute pleasure to work with. I would highly recommend Matteo from McCormick home builders for any home building projects, and we will be calling him again in the future!"

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