"Let's start with the bad. John did leave a few scratches on a couple of small areas. Since I'm a perfectionist this did not sit well with me, but, I accepted it since everything else was perfect and the scratches are not that noticeable. As soon as I met John I knew he was the one to reface my cabinets. He struck me as honest and straightforward. I did not check out prices. The price he quoted me sounded fair and I liked his demeanor, so I signed on the dotted line. I don't regret my decision at all. The kitchen is just Beautiful. He did a Splendid job and as others have mentioned he is super neat, careful, and conscientious. He is a hard worker in the best way possible. He is never in a hurry to get your job out of the way so he can start a new one. I have already recommended him to a few of my friends. Because of those scratches I mentioned before I am only giving John 5 stars and not 6 (if I could have)."

Customers say: Quick response

"Mike was on time and quick on the draw for starting projects. We used him to finish the kitchen for us. I want to say that when he came in, our house was a disaster due to a plumbing leak in which insurance was working on with their contractor. Mike didn’t skip a beat, worked around everything and did a fantastic job on the backsplash and the can lights. I feel a little bad because I’m fairly talkative and I found several other projects for him after we decided we were listing the house. His work has been outstanding on every project so far and can tackle many jobs. He’s is about to start painting our house this week and has fixed several issues in the meantime. I would recommend Mike over and over."

Pre Made Cabinets FAQs, answered by experts

Installation typically takes 2-3 days, depending on the kitchen size and preparation needed.

It can take anywhere from two to six hours to install bathroom cabinets, depending on the complexity of the project. Keep in mind that this doesn’t include the time to build custom cabinets if you go that route. You can also expect the project to be on the lower end of the range if you hire a pro, as opposed to DIYing the task.

Typically, a medicine cabinet should be installed about 60 to 72 inches above the floor. This height ensures that it's easily accessible for most individuals while allowing for proper visibility and convenience. However, the ideal height may vary based on individual preferences and the average eye level of the users in your household.

Storage cabinets can be custom or standard, depending on the purpose of the cabinet, size of your space, and available materials. If you’re looking to build something to a standard size, the usual range for cabinet dimensions are as follows:

  • Height: 12 inches–42 inches

  • Width: 12 inches–36 inches

  • Depth: 16 inches–24 inches 

Taller cabinets typically have a height of 84 inches, 90 inches, and 96 inches.

If your walls aren’t plumb, it can make installing frameless cabinets difficult because they require precise measurements so they don’t show imperfections. Any dissymmetry with installation can cause the doors and drawers to not function correctly. Frameless cabinets are also thicker and heavier, making them harder to install by yourself.
