"Esther was very easy to work with and gave us a nice design for our bathroom re-do."

"It was a pleasure to work with Eric, we hired him for a complete backyard renovation which included tree removal, leveling the surface and place pavers and a deck on top. Also built a retaining wall. The work came out very nice in part because of the great design ideas that Eric gave us. The project ran into some unexpected issues that Eric was able to overcome nicely. We were impressed how Eric handled the project and met all the deliverables, also his team was extremely polite an professional. Our backyard now looks like the ones advertised in magazines. All this led us to start a new project with him to replace the cracked driveway with nice new pavers."

"We bought a condo in Newport Beach and hired RASA construction to finish our project that included one room and a full bathroom addition, remodeling of the entire condo. They did a great job and delivered it on schedule. We definitely recommend this company and you wonâ t regret hiring them."

"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

"We loved working with Shilpa! She helped us design an addition of 700+ sq ft to our home and it has turned into our dream house now. She worked great collaborating to figure out exactly what our needs were and were we blown away with the final design we ended up with. We are hoping to do some more remodeling in the future and Shilpa will definitely be our first call."

"Ovation manages client contracts and finances while Unique Interiors (Kris Tavares) crews do the work. Overall, the construction was of average quality, and am I generally satisfied with the results. Most workers were timely, friendly, and cleaned up after themselves. However, there were a number of issues of missed timelines, demands for early payments (although the total paid was as agreed). Several of the subs or workers were problematic and callbacks from both Ovation and Unique were difficult. His work was often installed where other work was planned. As a result, his work needed redoing. Because he was rarely quickly available to fix his mistakes, these erred installations significantly increased the project duration. He rarely cleaned up after himself, leaving scraps, and construction debris left where he worked requiring other workers or the homeowner to clean-up. His worst mistake was drilling a 3 ½ in a hole in an array of standard 2X4s to accommodate a 2 in conduit to pass through. The result was that the involved wall required reconfiguring to ensure structural soundness. This event was complicated by his using brute force to remove a frozen stud in an electrical meter base, which then broke off. Instead of drilling out the broken stud, he ordered a new service, which necessitated a two-week period with no electricity to the house. Not only did this delay the project, if necessitated people living here to vacate during this time and required use of an extension cord from a neighbor to keep the refrigerator and freezer running. This alone was cause for a 3-week delay in the overall project. A number of other delays were the result of materials not ordered in a timely manner so that when workmen were assigned, instead of beginning work on the ordered materials, they had to go find what was needed at the store. In some cases, this required ordering materials that were back-ordered, adding to the delays. It must be said that this small project was originally projected to have an elapsed completion time of 1 month. In all, the project took over 4 months with many interim completion dates given and passed. These delays were complicated by two international trips the owners took, one of which I hired a person to oversee construction in my absence, the second because of problems in my first absence, I halted construction for 3.5 weeks while I was gone. The person hired to install cabinets, which were very nice quality, were hung in a very unprofessional manner with screw heads exposed inside the cabinets and many of these proud of the cabinet wall, which prevented me from using screw covers. About cabinet designs: I was presented a cabinet plan and pressured to approve it. We discussed the plan and made some agreements of the changes needed and I signed off. Unfortunately, all the changes we discussed were not followed and some original designs were ordered. This was my error for signing off to a plan without better documentation of the oral changes.Part of the plan was the installation of a shallow counter that needed custom fabrication. The finish material had to be repaired and this did not work so it was agreed to replace the counter as warranty work after the project was completed. The person who built this also undertook the redo. The final quality of the work was very poor. The counter was somewhere from ¼ to 1/8 inch away from the wall. He attempted to fill the gap with silicone and smeared it on both the wall and the counter. He left the redo in this condition without letting the owner know he was going. I reported this issue to both Ovation and Unique, without any response. I had to make the repair on the counter myself."

"I’ve worked with Mike and his team for years on all kinds of projects, and they’ve always been amazing to work with. The quality of their work is top-notch, they stay on budget, and everything runs smoothly from start to finish. Their design sense is excellent and they always manage to get things done right on time. I can’t recommend them enough, truly a reliable, talented, and easy-to-work-with crew."

"Nickelson Ink did a fantastic complete remodel of my kitchen and installed new flooring everywhere with the exception of the bedrooms. Curt Nickelson was instrumental with the design and answered any questions I had throughout the entire process. His crew were polite, clean and professional and the job was completed on time. I love my new kitchen and highly recommend them for any home remodeling projects you have."
