"Arroyo Brothers are experts in every phase of the construction process. They can act as general contractors or specialized craftsmen. We have enjoyed their expertise for 20+ years. They completed a major exterior remodel for us, including cedar shingle siding, construction of 2 new decks, a new roof, and a portico addition. They also completed major interior remodeling including a complete kitchen remodel, bathroom remodel, and bedroom addition. They have remodeled our yard, including the construction of a magnificent flagstone firepit. They have worked with our interior designer to ensure impeccable results. The quality of their work is extraordinary. They are dependable, conscientious and efficient. Once you hire Arroyo Brothers, you will never hire anyone else!"

"Jorge did an outstanding job remodeling both of our bathrooms and replacing all of the water pipes throughout our house. The quality of his work was excellent, and everything was completed professionally with great attention to detail. Jorge is reliable, trustworthy, and extremely responsive. He kept us informed throughout the project, addressed our questions promptly, and always followed through on his commitments. He is someone you can truly trust to do the job right. On top of that, he went above and beyond by replacing a few additional items at no extra charge, including our kitchen sink and several shutoff valves. Those thoughtful extras showed that he genuinely cares about his customers rather than just finishing the job."

"Our roof was in bad shape and we needed to have it replaced. I had gotten estimates and decided to go with Home Pro Remodeling. Emil and Brian were our contact people for the project. Emil was very professional and paid attention to our concerns. He worked with us through the entire project to our complete satisfaction. Brian is extremely courteous and helpful as well! The project went very smoothly, was completed before the initial project end date, and the results were beyond our expectations. The job turned our beautifully! Our new roof looks FANTASTIC! Our neighbors have commented to us how great it looks. We are very pleased with our experience with Home Pro Remodeling and would definitely recommend them."

"We met Mike at the San Jose homeshow.  He seemed like he had a lot of experience.  We liked the idea that everything was handled in house, from design and engineering to building. 
Mike was great at returning calls, follow-up and making an appointment.  My husband and I had basic plans we had created showing the idea of our project and were trying to get an idea of if we could afford to start the project.
We made an appointment for Mike to come by.  He called when he was supposed to arrive to let us know he was running late but would be there.  When he arrived, he seemed like he was already off to his next appointment.  He was very much in a hurry.  He did a lot of talking about his ideas, but not a lot of listening as to what we were thinking.  He did have some great ideas as to what he would do with the project.  He dismissed the research we had already done on the project.
After this brief meeting, he took the drawings we had prepared and told us he'd get back to us with an estimate for architectural and structural engineering services.   He never got back to us.  We didn't follow-up with him because we didn't feel like we would be a good fit.

Mike gave me a call after seeing my review on Yelp and on Angie's List.  He apologized for my experience and explained that his mother passed away shortly after our meeting.  Due to his mother's passing he needed to take care of many of her affairs and deal with family matters.  I hadn't contacted him again as I decided we wouldn't be a good fit so knew nothing of his family circumstances.  He had misplaced my contact information.  Once he saw this review he could find me again and called me to apologize for this experience.  He offered some services with reduced rates to make up for my experience.  He also asked me to update this review.

I feel like Mike was sincere and apologetic and was really wanting to make things right.

"Jose was friendly and professional. My job was not considered large by any means (re-hanging a gate) but he completed it in short order and cleaned up after himself. I really appreciated the fact he wanted to insure I was satisfied with the work because he needed to cut an inch off of the gate.....which I was. I would certainly call him again."

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