"I found these company online and I hired them to replace all the existing windows and patio doors with new fiberglass (Milgard) Ultra windows and a double French door from them a few months ago for our renovation. They provided us with an awesome price for the windows and doors themselves and for the labor of the installation as well. The representative that I spoke to was very professional and he came over to my house on the time and day that was scheduled ahead of time via the office. The people that we were involved with (including the installers and the sales man), was definitely outstanding. We had a minor issues that accorded during install, and they provided awesome post-sale support as well. I recommended them to all my friends and family as a great company for any energy efficient products. They are fantastic. And have some Sunday hours, which is absolutely a great help. We purchased 2 additional exterior doors from them and this was an add on that we decided to do in the last minute and after the work was stated. We were sure that they won’t be able to do it during the same time… but they did it and it went so smooth and excellent. Should've gone to Landmark construction energy crew for those too. You can shop with confidence with them!"

"Our bathroom was outdated and cramped, so we decided to remodel with Ocean Seven Builders. Ron was involved throughout the process and made sure we understood each step. What stood out most was how organized everything felt once the work began. The team was respectful of our home and finished the project close to the expected timeline. The final result looks modern and much more functional!"

"MGs General Construction is a professional, reliable and fair company. Mario is an excellent craftsman. He was on time to the job, courteous and thorough. There was an inspection made upfront to know what would be need for the job before or arriving. There was suggested material appropriate for my style and theme of my home. They did more then expected and had knowledge to look for issues of an older home, in which I had multiple service calls from another company to try to remedy the problem that Mario was able to pin point and tackle the problem. I recommend MGs to anyone who needs a professional, dependable and knowledgeable general contractor. His pricing was more then fair, and he did a total cleanup after the job was done."

"MJ builder exceeded our expectations. While most builders are struggling with supply chain and labor issues MJ didn’t miss a step. They are reliable, efficient and professional. They recently remodeled our living room; removed existing gas fireplace, installed new energy efficient fireplace, refaced/repainted, addressed numerous electrical issues, and retitled cracked travertine tile. They did this in 3 days and cleaned during and after they concluded our project. We LOVE the outcome! MJ will be our go to for all future projects and so grateful to have met Connie & MJ team who’s as honest and hard working as they get. Connie talked me out of unnecessary work. Who does that? Thanks Connie & MJ team!!!"

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