Customers say: True professional

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice.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!"

Pre Made Cabinets FAQs, answered by experts

It depends on your carpentry skills and the type of cabinets you purchase. If you have a high level of skill, then it’s most likely going to cost less for you to build your own garage cabinets. It will take longer than purchasing pre-built cabinetry, but it will decrease your overall labor cost.

Building a bathroom cabinet can be cheaper than buying one, especially if you have woodworking skills and tools. The cost of materials can be less than that of a premade cabinet. However, buying a ready-made cabinet might be more convenient and cost-effective if you factor in your time and effort. Custom-built cabinets offer more flexibility in design and materials, while pre-made options provide ease and faster installation.

It’s best to stick with lightweight cabinets, such as medium-density fiberboard, if you don’t have a wall stud to secure them to. Unless you’re attaching the cabinet to a flat board attached to wall studs, it’s best not to risk it with heavy cabinetry or contents. Solid wood cabinets and heavy dishware should be avoided if you cannot secure the cabinet to a wall stud. Either way, always check the weight on your wall anchors and be sure not to exceed it.

To install cabinet doors evenly, it’s important to make sure that all drilled holes and hardware are in their right places and aligned properly. You can achieve the ideal placement by using a level, straightedge, or other measuring tool. In the event that your cabinet doors are not installed evenly, most hinges allow you to adjust them so that your doors can be perfectly lined up. 

There’s no strict rule about which way cabinet doors should open, but generally, double cabinet doors should open away from each other. With single doors, you want to avoid having them block your path or swing into  areas where people need to stand. Some kitchens are angled so that cabinet doors may crash into something no matter which way they swing, but the methods above can help prevent damage.
