"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"Did a good job initially. Did not install small plugs that cover the screws holding the window to the frame. Failed to respond to come back and do it. Some cosmetic drawback to their good job. Weak customer services!"

"It went very well! Aviv did an amazing job with the project ! He was extremely friendly and kept in touch during the entire process! I was skeptical because I just recently moved here but Aviv and Goodfellas Construction actually went beyond what I was expecting ."

"They are very polite. They keep moving and get the job done. They go above and beyond. I thought they would be done with the windows by 4 pm, they actually were done at 6 pm, with adding little things on, and they didn’t charge me extra. They do a good job of hanging Christmas lights and usually have pretty good suggestions, based on what I want of where the lights should go and so forth."
