"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

"it was not a remodel, but there was no other option for me to choose. The work that was done was miscellaneous in nature. It was prep work for a listing to be put on the market for sale post a tenant move out. So painting, microwave put in fixtures of door handles face plates, just a checklist of a number of items. It was wonderful working with Mike. He was kind he was polite. He was on time gave an estimate stay to it. It was very detailed when certain things came up certain plumbing issues sent me pictures and gave me descriptive information. Will definitely be working with him again and a very enjoyable experience."

Pre Made Cabinets FAQs, answered by experts

Kitchen cabinets can hold a whopping 500 pounds, but that is only possible if you attach them correctly. They must be anchored securely with long screws driven straight into the wall studs for solid support. Depending on your cabinets and the installer, some upper cabinets use specialized hanging systems or brackets for extra reinforcement, ensuring they stay put no matter how full they get.

Yes, there are some options for pre-built inset cabinets—and RTA ones, too—but the selection can be somewhat limited. Many homeowners who decide on inset cabinets choose to have them custom made. 

The cost of bathroom cabinets is $550 on average. You could spend as low as $330 or as much as $42,000 or more, depending on the cabinet size and the type of cabinet you choose. 

Stock bathroom cabinets are the most cost-effective option, ranging from $40 to $500 on average. Semi-custom bathroom cabinets range from about $500 to $800 per unit (without installation costs) and offer a wider variety of door and drawer styles than stock cabinets. Custom cabinets range from $700 to $1,000 or more per unit before installation costs. 

The cost to install a kitchen island ranges from $900 to $6,500, with an average price of around $4,800. The final cost depends on whether you buy a prefabricated unit or have one custom-built. Prefabricated kitchen islands are generally cheaper. A simple prefabricated cart can cost between $150 and $900, while a permanent, stationary prefabricated island costs from $900 to $5,000. A custom-built kitchen island averages around $4,800 but can cost $10,000 or more depending on factors like materials, size, design complexity, and accessibility.

In a kitchen installation, starting with the foundation and structural elements before moving on to the finishing touches is essential. Framing, plumbing, and utilities should go first, followed by cabinetry and countertops, then plumbing fixtures and new appliances. Flooring, paint, tile backsplashes, and similar finishing touches should get installed last.
