Remove and replace countertop

• 1). Measure the countertop. Builders usually design kitchens around standard lengths. Don't count on this. An inch or two either way can make the difference between a successful job and a big mistake. Make sure your replacement countertop is the same size as the original.
  
  
• 2). Empty the cabinets and remove the drawers under the counter. This may seem like a lot of work, but it will make it much easier to remove and reattach the counter.
  
  
• 3). If there is a sink mounted in the countertop, close shutoff valves and detach plumbing. Open the faucet and allow it to drain before unhooking the P trap.
  
  
• 4). Locate attachment points and remove fastenings. A flashlight will come in handy here. In most cases, countertops are secured with wood screws. However, some builders prefer an adhesive compound. If no screws are present, you may have to use a flat nail bar to pry the counter off the cabinet.
  
  
• 5). Remove counter from cabinet. If you plan to reuse the sink, remove it and set it aside before lifting counter.
  
  
• 6). Measure and cut a hole in the new counter for sink installation.
  
  
• 7). Place the new countertop in position. Be sure the backsplash is flush with the wall and the countertop sits evenly and securely on the base cabinets.
  
  
• 8). Secure countertop in place with wood screws or construction adhesive.
  
  
• 9). Install sink and reconnect plumbing.
