"Overall the project went very well. They communicated effectively. They were flexible and responded to our concerns in a timely manner. They altered the floor plan of our old, disastrous master bathroom and created a walk-in closet. This was all done according to a layout we came up with. Prior to project commencement we discussed with Jim and America what we wanted. We were clear on the layout though sketchy on the details. They drew up a contract that itemized what would be done and the price for it. The contract included a payment schedule. We added on some extra work during the project that increased the final contract price by about 10%. The bathroom fixtures, vanity and countertop, tiles, shower glass and closet organizer were not included in the contract price. Things like the demolition of existing stuff, installation of fixtures and tiles, framing, drywall, painting, electrical wiring, and the under plumbing were included in the contract price. The demolition was fast and efficient and done with minimal mess. They built a stand-in shower, rerouted the plumbing for a bathtub and toilet and wired an electrical layout. They also installed new windows, lights, ceiling fans, a vanity and hung doors. The framing, drywalling, plumbing, electrical work, painting, fixture installations and finishing work were all excellent. Our only complaint is that their tile subcontractor was a bit sloppy. We had him replace some tiles he chipped during install. These replacements were done at the contractor's expense. There were a few project delays that were mostly from our end. For example: the freestanding bathtub we wanted was out of stock and had to be backordered. It took a good 2 months to arrive. OC Home Builders made suggestions as to designers and suppliers. We went with some of their suggestions such as which mirror and shower glass installer to use. However, they worked just as well with suppliers we chose. Things would have gone more smoothly and quickly for us if we had known ahead of time exactly what we wanted and had it lined up to go. During the project they were respectful of our home and privacy as much as one can be during a remodel. They were responsible to be left alone on the premises and they locked up the house if they left when we were not there. They made efforts to keep the dust and paraphernalia confined to the work area of our home and they did a good job of that. They didn't leave a mess when they left. The final result looks good and works great. Jim and America Fischer and their crew got the job done."

"Full kitchen and bathroom remodel. (Loft condo) From my initial meetings with Anar the owner, to meeting the team that did the install It was an entirely stellar experience. Anar presented me with samples and a clear understanding of the project scope. A project manager was assigned that came out to the site on a regular basis to monitor progress and quality. The two gentleman that came out to do the installation were personable..and maintained a clean workspace and professional attitude throughout. Both obviously skilled for the job duties. There was great care taken during the project on communication regarding the installations, and leaving the site as undisturbed as possible (clean) and with respect to property rules. (Condo). The fixtures and materials offered were all top quality and brands. Project oversight and city permits were all handled by the project manager. A very high level of communication and attention to detail were provided throughout the project. My spouse and I are very happy with the results, and this is added tremendously to the value of the property. This is our first remodel, and although it is an inherently stressful undertaking, Anar and his team really delivered with service and quality. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ gentleman! Thank you again! I recommend working with this team👍"

"I really enjoyed working with Mike, Chris and June. I had high hopes of getting into our remodeled home within the allotted time that was discussed in the contract but when Covid hit it made the process much longer. Our choices were out of stock or were coming in later than promised. But overall Mike and his team were so professional and so honest with me and my husband about what step they were on or any problems that came up. I would definitely recommend and rehire again in the future. Thank you Mike and Chris"
