"Al and his assistant installed two window air conditioning units in windows that another installer said could not be done. The other installer from TaskR installed one of the units in a non-preferred window and left quite a mess, including crooked drill holes in my wooded sills. (My place is 105 years old, but my window sills have metal frames and modern windows.) Al and his assistant’s work was perfection! I was so pleased, I have already referred Al to 2 neighbors. Al is great at communication, very pleasant to work with, and honest. They cleaned up everything and offered to take the boxes and packing materials out to my bins. This was a relatively small job, but worth the money. Al charges a 2-hour minimum, which is more than fair. I will hire Al again and continuing recommending him and his team."

"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."

"We had a number of repair and upgrade projects to do in our house and started searching for a contractor in March. We received bids from three different companies, but none of them followed through with a contract. Finally, in July, we received a recommendation for Remodels and Repairs On Demand and they turned out to be outstanding. Charles provided a detailed bid and was very flexible when we requested a couple of changes, even after the work had started. They stayed on schedule and kept us informed with each step of the process. Charles and his team from Repairs and Remodels On Demand were honest, polite, punctual, very well organized, easy to work with and finished the job on time. We are very pleased with their work and would highly recommend this company to others."

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.
