"Efrain and David are fantastic! When our contractor was suddenly unable to continue with the job, David took over with a great positive attitude. He persistently worked with the city to get the building permit, finally ending a tedious 10 month process. Crews were here working every day. Each one of them was considerate, conscientious, and demonstrated a strong work ethic. Efrain and David communicated with us most days and were always accessible to us. My ADU is adorable and just what we wanted and I am sure that many contractors could have pulled it off. The important thing about Olalde is that they truly care and honestly want us to be happy."

Here at Embee & Associates, Inc., we pride ourselves in a job well done. With an eye for detail, we will help your dreams become realities so please contact us today for a fast and friendly service that you will not be disappointed in!!

"Overall my experience with this company was great! The work that was done was really really good! Our contractor who assisted us was Jose. We added a living space and master bedroom to our home. The additions done look as if they were part of my house this whole time. Honestly it looks way better than I expected. The only reason I rated the company a 4.5 was because there was always some kind of miscommunication between our contractor and his workers. Don t get me wrong, things were always resolved, Jose was great at that. But my recommendation to is to make sure communication is #1. That way the customer is not confused or left wondering what will happen next. There was an issue with his floor guy though, he was rude and unprofessional. BUT the reason I am mentioning this is not to put down the company but let you know that we expressed concern for this issue and it was resolved professionally by Jose and it never became an issue again. The quality of work was top notch! His workers were all pretty cool guys and we always felt comfortable of who was coming into our home to do the work. I highly recommend this company for your next big project😊👍🏼"

"This is our second project with Horizon Construction & Remodeling. They originally remodeled our primary bathroom. They did such an excellent job with that, so we brought them back to remodel our kitchen and upgrade our electrical panel. We had a good idea of what we wanted, but Mark helped walk us through our design. He made several suggestions that helped improve our design and function in the kitchen. The staff that did the work were extremely polite and professional. They cleaned up after each day of work and were overall respectful of our property. They showed up when they said they would be here. Not only does everything look great, but the quality is also wonderful! As our house was built in 1958, we did find problems with the plumbing for gas and water. We needed to replace all the lines, so we had the whole house replumbed.

"Jorge, Andy and their team at A1-Builders were knowledgeable, honest, reliable and above all always available to answer any questions we had. They helped build a 2 bed 1 bath 600sqft addition to our home during the lean months over the pandemic. We had multiple projects (pool, patio, retaining wall) going on at the same time with other contractors and the crew from A1-Builders were by far the most professional. They always made sure that they left their work site clean after each dayâ s work. Jorge will definitely be the first person I call for our next home project because I know that even if he does not have the time to do the work, he will always guide me in the right direction. Thank you again to the entire A1-Builder team!"

FAQs for major renovation multiple room service projects in Corona, CA

Remodeling almost always costs less than building from the ground up. You’re working with an existing foundation and framing, so you skip the hefty price tags tied to new structural work and the extra permits that go with it. Keeping your current footprint also streamlines scheduling and cuts down on materials, giving you a financial edge while preserving the layout you already know and love.

Timelines swing from a few days for quick cosmetic fixes to well over a year for a whole-house overhaul. Fresh paint, new fixtures, or updated flooring can wrap up in a weekend, while tearing down walls or moving utilities can stretch six months or more. Build extra time into your plan for permits and surprise repairs, and keep a tight schedule with your contractor to stay on track.

Call your insurance agent before the first demo day. Standard homeowners policies cover basics like fire or storm damage, but big upgrades that boost your home’s value can leave you underinsured. Ask about a renovation rider or similar add-on so new square footage, finishes, or systems stay protected from day one through final inspection.
