"Del Mar Landscaping is a top notch outfit. They do everything from start to finish. On time and the crew is amazing. The job took a total of two weeks and the crew cleaned up every day. Would recommend their services to anyone that wants a professional company that takes pride in their work. We get daily compliments of how great our house now looks."

"As an investor who buys properties oftenâ ¦ I am always in a search for a reliable, honest, capable and nice people to work with. Eran and his crew at ESL Designs are one of the best contractors that I came across recently and now I know that if they will get involved in any other remodeling project with meâ ¦ they will do it on the best side and without any delays or issues that canâ t be solved. The reason for my that caused me to hire them was to remodel a new investment house that I purchased recently and that required the remodeling of the bathrooms, small repairs in the kitchen and hallways, including some improvements in the front of the house. Eran has a large experience in the industry and he proved his design skills to be perfect for what I needed. In my industryâ ¦ itâ s hard to find someone that have a great knowledge, ideas, solutions and design experience. Eranâ s work came out perfect and i will do more business with him and ESL Designs on every remodeling job that I take on."

"Edward was able to take my basic idea for a porch design and elevate it to a level I couldn't have imagined initially. He was very communicative throughout the process and made the whole process a breeze."

FAQs for design and decorating projects in Diamond Bar, CA

Start by defining your goals and budget. Collect photos of rooms you love, jot down must-have features, and list what isn’t working in your current space. Share these details—and your target budget—during the first meeting. The clearer you are, the quicker a designer can translate your vision into a workable plan and keep costs in check.

Yes, working with an interior designer can help you save money. Designers prevent costly missteps, secure trade discounts on furniture and finishes, and coordinate the project so you don’t pay twice for the same work. Their upfront fee often pays for itself in avoided change orders, tighter timelines, and materials purchased at below-retail pricing.

A full interior design project wraps up in two to three months, on average, while a decorating job takes four to eight weeks. Timelines stretch if you add structural changes, custom millwork, or specialty materials, and unexpected shipping or permit delays can tack on extra days. Talk with your designer about project milestones and build in a little wiggle room.

Interview at least three pros whose portfolios match your style. Review their credentials and ask for references. During a face-to-face or virtual meeting, discuss your goals, budget, and timeline, and make sure their communication style and fee structure feel comfortable. The right designer combines technical know-how with a creative approach that clicks with you.
