"TERRIBLE experience. Complete lack of supervision of subs, shoddy workmanship in many many areas; refused to correct at his own expense his subcontractors installation of pocket doors, where the sub incorrectly modified the factory-supplied frame assemblies. Complete incompetence and complete failure to take responsibility for any work he arranged."

"We hired The Home Remodeling Guys to remodel both bathrooms in our home, and the results are fantastic. From the initial consultation to the final touches, their team was reliable, skilled, and easy to work with. They helped us modernize both spaces with updated vanities, new tile work, lighting, and fixtures. One of the bathrooms had some plumbing challenges, but they handled it quickly and professionally without delaying the schedule. The crew was respectful of our home, kept the workspace clean, and stayed on track with the timeline and budget. Communication was consistent throughout, and they were always available to answer questions or offer helpful suggestions. Both bathrooms now look fresh, functional, and beautifully done—we’ve gotten tons of compliments already!

*Please Call Directly* WE SPECIALIZE IN COMPLETE REMODELING PROJECTS WITH A MINIMUM COST OF $5,000. We are a team of skilled craftsmen each with many years of experience remodeling kitchens and baths in the Orange County area. At Coastal Kitchens Inc. instead of a showroom we use door style, finish and kitchen cabinet samples, as well as photo design books and CAD on laptops to display your kitchen as it is designed. This way we eliminate the need and the cost associated with a showroom business model. This makes the design process more convenient for our customers, and we pass the significant savings on to them as well. Our design process also allows us to spend more time working on our customer’s designs. This is what we enjoy most about our business and it is what makes the difference between an average and a great kitchen design. Why should I work with Coastal Kitchens Inc.? John (the owner) has 34 years of experience in the remodeling field along with his experienced team. Our top priority is ensuring you receive the highest value for your dollars. This means we will sometimes suggest less expensive options for some aspects of your kitchen to accommodate better investments for others. For example, we can often recommend a cabinet door style that will appear identical and cost substantially less leaving you more dollars for your overall renovation. One of our guiding principles at Coastal Kitchens Inc. is that the best investment in your kitchen is always your design first and your door style second. Exceeding expectations, but never your budget. Contact us through email at coastalkitchens@cox.net for faster response. Credit card purchases are welcome however we charge a small convenience fee.

"We are so glad we chose Coastal Kitchens and Baths Inc. for our remodeling project. They did such a great job on our master bath, guest bath, and the flooring throughout our house. The luxury vinyl looks amazing and completely transformed our home. John was very hands-on and made sure everything was completed with attention to detail. I could even text him late in the evening—sometimes around 9:30—and he would respond right away. That level of communication and dedication made the whole process smooth and stress-free. We are extremely happy with the results and would definitely use Coastal Kitchens and Baths Inc. again."

Opulent Design Build . One point of contact from Start to Finish. Opulent Design Build takes the complicated process of home designing, building and remodeling and makes it an experience that you will love! There's no need to fear the design & construction process. Opulent Design Build personally handles every aspect of the construction process: design, engineering, site survey, permitting, construction and inspections. We are truly a "one-stop" design-build company.

"My wife and I were looking into adding some square footage to our home as well as remodel. We were going in circles trying to plan and budget and it honestly was one of the most stressful/hardest experiences of our marriage. That was until we stumbled upon Opulent. I do not remember how we found them, but man, I am so glad we did. Eddie and his whole team were OUTSTANDING throughout the whole process. They really made us feel like we were part of the Opulent Family as well as producing real results. They managed EVERYTHING just about perfectly. From dealing with the permit process to helping us figure out what we needed to fill our space with beautiful fixtures to actually getting the construction done. The preconstruction process was so simple thanks to their amazing team and construction flowed so smoothly. The field workers were respectful and clean every day. 10/10 cannot recommend enough. Thank you Opulent!!"

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