"I had the pleasure of working with Ariel from My Construction Group for a fairly large remodel (two balconies, one room addition, and one great room expansion) project on my home. I was very pleased with the completed work and even more impressed with their attention to the customer experience. This truly differentiated them from other contractors I have worked with. I would highly recommend My Construction Group to everyone."

"After a failed attempt on my part trying to redo our kitchen we decided it was time to leave it to the pros. After getting several bids, we selected clever. The communication process was great, our GC was phenomenal, and the work was completed to a high degree of quality. I would definitely use them again. It is nice to have a kitchen that looks great and complements the rest of our house."

"The Hall and Master Bathrooms were fully renovated with new cabinets, countertops, showers and fixtures. Leo from Skytech assisted me along the way with option choices and recommendations. The crew was exceptional in their workmanship and were very detail oriented and made sure to clean the area prior to departure each day. I have received multiple compliments on the finished bathrooms. I would highly recommend Skytech Builders to anyone considering renovations and Leo in particular."

"We want to add to our earlier review. Carnhill Construction has been our go to for the past 6 years. They have dealt with a stone deck that kept leaking refuse down the facade, painted our entire house inside and out more than once, had our wood floors sanded and refinished, repaired cracks and leaks in the siding of the house, repaired a balcony. They have been very creative and innovative in coming up with fixes. As we stated earlier they are professional, reliable, consistent and their communication is immediate. We rely on them to deal with any house repair we need. They are a pleasure to work with. We would recommend them highly to anyone needing any house repairs whether a small or extensive project. "

FAQs for addition to existing structure building service projects in Portola 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.
