John is the most helpful and honest person I have ever worked with. He didn't try to take advantage of me because I was a woman. He walked ne through fixing my issue and he was very patient and understanding. He really cared! To all you women out there who are looking for someone to help you while being honest and charging a fair price, this is the company!

Got our first quote from John the owner of the company he was straight forward and recommended that we get other estimates but he backs the quality of his work. Spoke with a few different contractors for our remodel and decided to go with SouthStar, there was constant communication throughout the whole process. The company did a great job and I would 100% recommend them to my friends and family, great family company!
Thanks!
Thanks!

Well, it wasn’t easy working with the city of Norco on building at 900 ft.², two bedroom, two bath ADU in our backyard but we got it done! Thanks, John, and all the Southstar Construction workers who made this happen and worked through a number of challenging situations that occurred along this journey! I don’t know if I do it again, but if I did, I would certainly rely on John and Southstar to get the job done and get it done right.

We couldn’t have been happier with the work that was done by SouthSTAR Construction when we had our balcony torn down and rebuilt.
John and his team were very professional, showed up on time, paid attention to all the little details needed, always cleaned up at the end of the
day, and always communicated throughout the job on what was being done.
I’d highly recommend John and his team from SouthSTAR Construction to anyone that needs work done, you won’t be disappointed!

If you're looking for honest contractors who have customer service in mind, this is the company to choose. I had an issue with a sagging joist in my bedroom floor which was visible from the ceiling below. I was able to cut out the ceiling on my own, take photographs of my issue, and send them over, without requiring an in person inspection. Afterwards, I received honest and sound advice as to what needed to be done to fix the joist. While the work has not yet been completed, I appreciated the quick, honest, and free advice. Even when I offered to pay, they said it would not be necessary and they were just happy to help. I strongly recommend Southstar simply based on this experience alone.

South Star construction did not disappoint! We waited years to replace our old enclosed sunroom and finally looked to South Star Construction for help. Owner John and his crew made the living space what we’ve always dreamed of. The whole crew made me feel very comfortable. I would highly recommend using South Star construction for any of your construction needs. I love our new room. Thank you!

Best ADU ever!
Southstar Construction did a wonderful job in building my ADU in Fontana. John the Project Manager was proactive during the whole process; from the plans, design, permits, to construction, and through the final city approvals. His crew were very talented and professional; knew exactly what they were doing. The team gave me feedback when I was unsure. They were very good communicators and were available to answer any questions that I had. It has just the right amount of space for me. Construction was completed timely and the pricing was reasonable for what I wanted. I truly recommend Southstar Construction. I really love love love my new ADU!!!

John and his team did a great job. Spent 2 days working on floors, baseboards and drywall for me in several rooms. Looks great and seems like there was no damage from our slab leak. Thanks John, appreciate the great work!

I messaged this company with inquiries about the home building process. John was very prompt in responding, and we set up a call the next day. I was very impressed with his professionalism, and authenticity. He took time to answer my questions thoroughly, and was genuinely taking time out of his day to help me with no gain of his own. He was honest, transparent and kind. At this time we are not building a custom home, but we hope to work with him when we do.

Just had two bathrooms remodeling projects completed by Rizk Construction, a master bathroom and a full bathroom. Rizk Construction is the real deal, John and his crew are the A-Team! Their work was excellent. The quote was competitive, the team showed up on time everyday, were highly professional and pleasant to deal with and were very attentive to detail. Not one minor detail was skipped over, everything was discussed with us during the project to ensure the final product was to our satisfaction. The pictures speak for themselves. I would highly recommend them.

John Rizk’s construction company remodeled our kitchen and did an excellent job. They demolished the old cabinets and countertops, hauled the old stuff away, and installed new cabinets and quartz countertops. The new cabinets are in perfect condition and have soft closing drawers and cabinet doors.
The electrical work was top notch and a lot of old issues were fixed including lining up all the outlets and light fixtures, which were previously uneven.
The employees arrived on time each day, were clean, friendly, and respectful and they cleaned up at the end of each day. They were a pleasure to have over each day and trustworthy. John the owner is very knowledgeable and affordable. Each day I am shocked at how great everything turned out. They made my house feel like a model home. I highly recommend Rizk Construction to my family, friends, and everyone looking for great quality at a great price! Very honest and reliable.

Let me start by stating how difficult it is to find a reputable contractor from the start. I was not so fortunate this time either in trying to solve a roof leak with potentially 3 financially responsible parties. Along comes John and Rizk Construction.
I had a room take the brunt of water damage via a mysterious roof leak during the 2022-2023 southern California rain storms. 4 months later Rizk construction to the rescue. Found the leak, repaired the sub floor and was able to find some beautiful re-carpet of my upstairs.
John was punctual, up front and was exceptionally professional having succinct yet exact contracts in the scope of work that was done.

We worked with Rizk Construction for the replacement of a stair railing and lighting. John’s crew was excellent. They were wonderful to work with, professional and went above and beyond what was required of them. They were very attentive to our needs. We are very pleased with the finished product and proud to show it off to family and friends. We will definitely use their services for future projects.
