"The folks a M&ES CONSTRUCTION ENGINEERING INC. Did a great job with my project. They renovated my garage, they drywalled and painted it, also gave me a beautiful epoxy floor thats easy to clean and a treat for the eyes. I also had them remove my old brick gas fireplace and build a tile faced electric fireplace with an insert for my Television. My TV fits perfectly and it looks amazing. Workmanship is top notch, they are transparent, punctual, and very communicative. Truly the best contractors I’ve worked with."

"We hired D2A Construction to build a detached ADU on our lot, and I’m still in shock at how smoothly everything went. Dani was an incredible project manager — responsive, honest, and always willing to take the time to answer our million questions. He kept the entire job running like clockwork, even when we had a few unexpected city inspection delays. His team was fantastic and the craftsmanship was solid across the board. We now have a modern, fully functional unit that we’re planning to rent out. It blends beautifully with the main house, and people can’t believe it’s a new build. If you want a company that actually delivers what they promise, D2A is it!"

"We had ACE Construction out to completely remodel our bathrooms in our 1909 farmhouse. We tore down walls and moved everything around because we didn’t like how the bathrooms were originally set up. They helped design the layout and helped pick materials. It was an amazing experience. All the workers showed up when they said they would and were very respectful. I would definitely use ACE on our next project and recommend to everyone!"

"We performed a whole home renovation inclusive of a bathroom addition. We needed design and build services for a 1960s home. The team was extremely professional and communicative which made for a smooth and thoughtful experience. The team was very organized in their execution and ensured all the decisions were made in a systematic fashion making the process feel easy. The day to day work staff was so respectful of my family as trades came in and out. For such a large project, it felt easy and detail oriented. We love the final product. It is absolutely beautiful."

"I had an excellent experience working with Larry McGee and his team at McGee Construction for my home remodel. From start to finish, Larry was professional, attentive, and dedicated to ensuring every detail was perfect. His crew was hardworking and respectful, completing the project on time and within budget. I’m absolutely thrilled with the results and highly recommend McGee Construction for any remodeling needs!"

"It’s hard to find an expert contractor that is also honest. John ensures his team produces high quality work. He’s there everyday to make sure it’s done right. The job was done expeditiously despite that his team was in high demand. It was much less stressful for us with his process to get everything delivered before the actual construction began. We love our new area so much that we hired him for our two bathrooms upstairs next."

"Benji and the ProHome Remodels team completed a room addition for us and did a great job. Benji did a great job managing the project and communicating updates clearly. We're very happy with the quality of the work and the new space looks like it was always part of the original house. We really appreciated Benji’s professionalism and attention to detail, we highly recommend him and would hire him again."

"I had an excellent experience working with Laguna Bay Developing. From the initial call and quote all the way through to project completion, they were extremely responsive and professional. Their quote was detailed and transparent, making it easy to understand exactly what I was paying for—no surprises or hidden costs. The work itself was completed on schedule and to a high standard. The team was respectful, organized, and clearly took pride in their work. Communication throughout the process was consistent and clear, which gave me confidence every step of the way. I especially appreciated their attention to detail and willingness to answer any questions I had. It’s not easy to find a company that combines fair pricing, reliability, and great workmanship, but they delivered on all fronts. Highly recommended!"

"Persi Homes did excellent work remodeling my master bathroom. I was very impressed by their professional and courteous attitude. They took their time to explain every single detail and suggested some great ideas of how to make the bathroom more stylish. The calculations were reasonable and they advised the materials that work the best for my bathroom. The project was completed on time and the quality of work is beyond my expectations. I would highly recommend their services, they are real professionals."
