"We recently remodeled our bathroom with McCormick, and it was a fantastic experience. Khaled was informative, patient, and genuinely helpful, guiding us through choices for a perfect design. The team’s professionalism showed in their punctuality and quality. Every aspect was done with care, from tile placement to lighting. The transformation is truly impressive; the bathroom now feels open and luxurious. We’re beyond pleased with the result and look forward to more projects with them."

"We hired Scott McQueen to totally renovate our existing barn, a very challenging project. We recently purchased this ranch property. The existing barn was quite old, probably built 50 years ago or more. Scott developed a plan to totally renovate it -- new trusses, new concrete floor (previously was just a dirt floor), new roofing, new siding, new electrical, new paint, new and strengthened interior walls, new doors, etc. Unfortunately we tackled the project at a time of high prices for materials and other elements, but Scott worked with us to significantly reduce costs from the original estimate by redesigning some elements of the plan and working with us to explore alternatives. We couldn't be happier with the renovation."

"Michael and team did such an amazing job on our bathroom remodel. They took our tiny, dysfunctional bathroom and turned it into a true master bathroom oasis in a short amount of time during the holiday season. When they had the space down to the studs, Michael sat down with us and discussed in detail the best possible use of the space and we couldn’t be happier with our final decision after going through the options. Michael was great at communicating and we still stay in touch to this day, which we truly appreciate. Great team who does great work and I will absolutely be giving Waters Construction a call for any and all future home renovations. I’ll let the pictures do the rest of the talking."

"Mr Neill Dougherty is an excellent custom builder, designer, communicator, and always professional. His prices are more than fair, especially when we saw the finished room!! We were somewhat unsure of exactly how we wanted the room, so Mr Dougherty helped us by showing several options that would work for our Mother-in-law studio addition. The room is absolutely beautiful! I love the flooring and custom tile work Neill created for the kitchen and restroom. Neill kept us up with all stages of the project, and was very accommodating and polite about my changes and "ideas" along the way. He even had an fantastic designer help me with Interior decoration after the apartment was ready! There has not been any issue we had to call back about. We will hire Mr Dougherty for any future building or remodeling we need! We highly recommend him for any project or home build."

"We had our deck rebuilt by The AI Construction, and we are extremely happy with the results. Angel and his team were friendly, hardworking, and kept the project moving from start to finish. The craftsmanship is top-notch, and the finished deck is sturdy, beautiful, and exactly what we wanted. If you’re looking for a reliable contractor for a deck project, I highly recommend Angel and his team!"

"Macc and his team did an excellent job on our deck installation project. Everything from helping us select the right materials, designing the layout, and completing the installation with quality and attention to detail. Everyone we interacted with was highly professional and left the work site clean. In addition to our decking project, Macc also subcontracted some really great concrete work for us which included a new driveway, front porch, and walkway, as well as some decorative stamped concrete in the backyard. This project went very smoothly and the end result met and exceeded all of our expectations. They also did some repairs to the exterior of our home/roof which included replacement of multiple facia boards at a reasonable price. Overall, we were very pleased with the quality of the work and the integrity and professionalism of Macc and his team, and we would hire them again for future projects. Highly recommended!"

"If you are looking for a knowledgeable, hardworking and trustworthy company, not to mention a kind, respectful, good communication and good person, Vitaliy owner of AVD Construction is who I highly recommend. Our project started as an owner build ADU garage conversion. We interviewed 3 subcontractors for each initial trade. Vitaliy was initially interviewed for framing, it was immediately evident that he was very knowledgeable about construction and codes. His pricing was fair and within other quotes, so we hired him. After a couple visits, and reviews of blueprints we discovered that Vitaliy was a general contractor. Since we were early on in our project, we would have him bid at each step, which we would choose him every time. As the project progressed Vitaliy would catch errors, by other trades and engineering. Most of these catches saved us time and money. There were times that he would fix some of these errors to help us out and save time. There is a specific example that comes to mind. Concrete sub had just poured their concrete, they took off the garage side door and our larger garage door wouldn't close. I was feeling very uneasy about having access to our garage and home from the street. Vitaliy pulled the door out of the pile of trash, cut it down to fit in opening, put hinges back on and wired garage door closed. I think he could see how happy and grateful I was, I remember saying "I think I'll be able to sleep tonight." Vitaliy said "treat other people's home like it's your own." That really stuck with me. Vitaliy made suggestions along the way, that made sense and often was overlooked by our novice eyes. He explained things, so that we could understand, he taught us so much. We are so grateful and lucky to have found him. We went on to hire AVD Contruction to frame, drywall, tape/mud walls, completely tile 2 bathrooms (floors and showers), Install 2 French doors, windows, all vents, stucco entire sides where new doors and windows were installed, plumb our kid's bathroom. Vitaliy was there for every inspection. Every job he took on, he and his workers were respectful, communicated each step of the way and they always treated our home like it was their own. If I had to do it again, I would have hired AVD Construction to do the whole project."

"Glenn and his crew from United Services went above and beyond my expectations. I had a bathroom gutted, water damage repaired and a whole new custom shower put in. The quality of the work is excellent, crew was reliable and very respectful. I also am having them build an oversized garage and cement handicap ramp for me, which is almost completed now, Glen even upgraded the garage door for me without charging me! Again, the quality of work is excellent. Glenn and the crew are very kind and patient as they explain things to me and helped me find the correct items for my projects. I unfortunately had several major plumbing emergencies recently while Glenn and his crew were working here. They jumped right in and worked with me to get the problems corrected offering me support throughout the whole process, making me feel more like family than just a customer. I highly recommend United Services to anyone who needs work done on their property, I guarantee you won't be disappointed."

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