"All City Installs was great! Melvin, the installer, was professional, courteous and highly skilled. He took the time necessary to make sure everything looked right. I would wholeheartedly recommend All City Installs. My only regret was not contacting them sooner. <br />"

"The entire process went smoothly. The reservation went quickly, once we paid an extra $200 to reduce the pickup window to 3 days. The pickup and drop off process also went well. The car was returned in the same condition we left it. We would recommend using United Freight."

"We had a great experience from start to finish with Shalom -- both with the owner Daniel and with the crew who did the work. It was a relatively small project, but Daniel was very responsive and worked with us to do the project during a specific time window. Everyone was extremely professional and the floor looks beautiful. Highly recommended. <br />"

"I hired C&A to finish my basement in the fall of 2022. Carlos and team were great to work with. They helped me with the design, and layout while giving me options for some much needed storage areas. I originally only hired C&A to partly finish my basement as I was planning on doing the floors myself. After they did such a good job, I hired them a 2nd time to install my LVP flooring."

"Alan is incredible. I've had a big complicated window treatment job I've been dreading - thinking it would have tons of issues, hard to get right, and thinking that it would cost a fortune. Alan came yesterday and did everything absolutely perfectly for SUCH a reasonable price. Hardware and curtains/shades are an art to hang and he totally nailed it all. In one room I had 3 windows for Alan to hang cafe curtains with some hardware I had purchased that didn't perfectly fit the window depth -- he made it all work perfectly. In another room I had him install outside-mount shades on five 90-inch windows, and then he hung a continuous curtain rod above the 5 windows around the 3 windowed walls with corner elbow bracket things and a piece that connects the rod to the 4th wall instead of finials. A lot can go wrong with that type of rod but he did it flawlessly --everything is just the right height, so straight, without a single mistake or unused hole in the wall. He's super easy to communicate with when scheduling and nice to have around. I'd hire again in a heartbeat -- he is just great!"
