How to Cut Vinyl Siding

The first thing you need to know is that there are three ways to cut vinyl siding:

  1. Short vertical cuts
  2. Horizontal cuts
  3. Long vertical cuts

The second thing you need to know is that when it comes to cutting vinyl siding, precision is key. Therefore, you’ll need to get your hands on the following tools:

Each tool is specific to each type of cut:

1) Short Vertical Cuts

Cutting tool: Circular saw

Circular saws allow you to make short, vertical cuts with ease as they can cut straight, clean lines without fraying the edges of the siding material. This is important because frayed edges can interfere with the sealing process.

2) Horizontal Cuts

Cutting tool: Utility knife

When you need to trim your vinyl pieces horizontally, you can use your circular saw or tin snips because the cutting points will be too short. That’s why a utility knife is your best bet for getting a close, precise cut.

3) Long Vertical Cuts

Cutting tool: Tin snips

Long vertical cuts are the easiest to make when using tin snips. They’re also much safer and will allow you to make more precise cuts compared to a circular saw, which can be a little bulky and hard to maneuver. 

Side note: It’s a good idea to keep all of your excess material in one place. This way, you can check your work and have a reference point to measure for replacement materials later on if needed.
