"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!"

"I could not recommend Ben Oded and his team more. I've now worked with Ben on multiple projects, including a new bathroom, renovations of existing bathrooms, electrical, plumbing, and most recently, an ADU, and on every occasion, Ben and his team have delivered. Ben is honest, reliable, and direct. When he says he is going to do something, I never have to worry about it getting done. He'll also be very honest with you about what's possible and at what price. There are also numerous examples of Ben going above and beyond. One such example was around my wedding. The week before the wedding, we lost all hot water...We had multiple plumbers over, but no one could find the solve. Two days before the wedding, we were scrambling. I called Ben, and within an hour, we had a plumber over, who fixed the issue and at a fraction of the cost. I could not recommend Ben more. Call him for your home or investment property renovation needs..you won't regret it!"

"I was looking for a reliable contractor on a room addition and after long searching I decided to go with Nir and LA Expert Builders. Not only they gave me competitive price, Nir completely understood what I wanted to do and he was available in most acceptable time. I worked with many contractors in the past and I can say that LA Expert Builders are one of the best I worked with, maybe the best. I am fully satisfied with the outcome and would continue to work with this company!"

He really educated us on what goes into an addition. He took care of everything and it went smoothly. We are really satisfied with the results and are so happy we went with Best Builders Group. They were always on time, honest and open to ideas and questions we had. If you are looking for a trustworthy and dedicated company then we recommend Best Builders Group!"

"The project manager, Tom Cohen, was so helpful from our first meeting. He was knowledgeable about the windows and explained the differences so I could make the best choice for the money I had to spend. The windows were replaced and I'm happy with my beautiful new sliding door. The work was done quickly and my home was left in great condition. I had no clean up to do after the workers finished. Tom helped me process all the paperwork and arranged for financing , also very helpful. I would use this company again and I would ask to work with Tom Cohen. I trust him to help with future projects."

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