"Seth and the whole team at Stel has always met all of our expectations. We recently finished our 2nd project with them. They have an incredible level of creativity that has been so much fun to work with over the years. Our last project was an addition to accommodate our aging parents on a single level of the home and turned out great, our current project was a complete remodel that we achieved the same level of quality and design creativity just like we did before. They have always been able to find solutions for our projects even with budget constraints. They have a fabulous sense of how to design around existing conditions so you really feel like that new part of the house was always there. They really do listen to you and take into account how a family really lives. A+ keep up the good work!"

"This company is absolutely the greatest. We worked on two projects with them. The room addition about 2 years ago came out flawless and the process went smoothly, plans were correct the first time, all inspections were passed. The project was on time. The second time, we remodeled our kitchen: replaced cabinets (custom), new countertops (white marble - very trendy), paint, and flooring. I suggest everyone who is thinking to undergo remodeling or construction to consider BD Project & Design first. They would not disappoint. Utmost professionalism and the best customer service. Thank you Kevin and BD Project & Design."

"We were quoted by 3 other contractors and Shiro definitely ended up being the most reasonably priced and also the most professional at the same time. We had a retaining wall and pavers put in with drainage, along with installing an extra propane outlet for a fire pit, and everything went as planned and came out great! Smooth and easy process, would highly recommend Shir and his crew."

"Excellent! Appointment was on time, and friendly and professional service. I had a jammed garbage disposal that was quickly determined to be from a soda can tab. Additionally, I had two wall sconces hung. I am very pleased with the work that was done."

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"I cant say enough about Nucave construction. Ryan and his whole team were very professional. I remodeled my kitchen and was looking for some custom pieces. Ryan knew what I envisioned for my kitchen and really brought it to life. I was also very pleased on how quick they were able to get the work done. I had some last minute adjustments to my design. Ryan was on top of it and was able to bring someone in to get it done asap. I will be hiring them again for more work."

"First project: I am very pleased with Repairs & Remodels On Demand (RROD). I was in the process of selling a property that was about 75 years old. The buyer's mortgage company had sent an inspector who noted several issues. Obviously I was under time pressure. RROD responded very quickly. I needed a hearth built in front of an existing fireplace. RROD advised me on what the current code requirements were. I selected material and the hearth was installed the next day. The inspector also reported six electrical issues, four plumbing issues in the kitchen and four in the bathroom. RROD repaired them all in two days. RROD sent a three man team. The timeline for the project was: Day 1, evaluate job and create estimate; Day 2, install hearth, correct electrical issues and begin plumbing work; Day 3, complete plumbing. On the fourth day I notified the buyer's agent to schedule the re-inspection; the inspection passed with no problems. Sale completed. Second project: In a rental property I own, a tenant wanted a laundry area. I had had the area plumbed but the walls had been opened to accomplish the plumbing. I needed the walls closed up, a short wall built, and the appliances installed. First day, evaluate job and create estimate. Two days later start and complete the job in two additional days. On the day after the completion, the tenant reported a problem with a door that had been installed. I went over and checked and she was correct. It was in mid-afternoon and I called RROD and reported the problem. They immediately scheduled an appointment for 8:00 AM the next morning (and repaired it on that visit). It was a small job with a small problem. The work looked very professional and the paint for the new areas matched the existing room colors. The point is, they do high quality work and they really do stand behind their work. I shall certainly use them again. I am very satisfied with their responsiveness and the high quality of work. They are easy people to work with. They came through for me. Dan"

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