How to Cut PVC Trim

PVC trim is used for many applications, particularly on the exterior of the house.

PVC trim is installed and cut in the same manner as wood trim and is virtually maintenance-free. This trim lasts considerably longer than wood and is resistant to all types of weather. It won't rot, splinter or warp and resists all types of insects. Cutting PVC trim is something that can be done using a miter saw with a carbide-tipped blade.

Measure the size of the trim board to be cut using a tape measure; write down the measurement on a piece of paper. Measure along the PVC trim board and mark with a pencil at the desired spot. Make the mark straight across, using a T-square for a perfectly straight line. This will ensure the exact cut is made.

Set the miter saw on a work table so it is steady and does not sway or rock. Install a carbide-tipped blade on the saw. Line up the blade to the correct angle so the proper cut can be made. Slide the trim along the fence of the saw and move the blade down so it touches the line it is going to cut.

Plug in the miter saw and grasp the lever. Turn on the saw and pull down slowly on the lever. Push through the piece of trim and let go of the lever while raising up to turn off the saw.

Repeat this procedure for the other pieces of trim. For angle cuts, set the miter saw at the desired angle and cut in the exact same manner as before.

Things You Will Need

  • Tape measure
  • Pencil
  • T-square
  • Safety goggles
  • Miter saw
  • Carbide-tipped saw blade


  • Always use a carbide-tipped saw blade when cutting PVC trim. All other blades will get worn out quickly when cutting PVC. The carbide-tipped blade is meant to last longer when cutting this type of material.
  • Check the blade periodically to make sure it is still sharp. If the blade begins to dull, change it to ensure the best cuts are being made on the PVC trim.


  • Always wear safety goggles when working with a miter saw and PVC trim.
