How Do You Install Vinyl Siding?


Installing vinyl siding is primarily a matter of cutting and measuring following by securing windows and doors and then locking the sections of siding into place and nailing them to the surface of the wall, leaving room for the expansion and contraction caused by changes in temperature. The project is a large one, but its mechanics are comparatively simple.

Installing flashing requires the use of a special tool, the zip tool. This tool locks one section of vinyl siding to the next.

  1. Install flashing
  2. Flashing and builder's paper should be placed around windows during the siding process. Builder's paper underlies flashing and prevents leaks and water damage. Flashing helps windows stay flush with siding. It must be secured with roofing nails.

  3. Install J-channel
  4. J-channel is vinyl material used to divert water flow away from windows. Exterior sections of window should always be framed in J-channel, which requires careful cutting and measuring. The bottom piece of J-channel is attached first, followed by the sides and finally the top.

  5. Install siding
  6. The siding itself is installed in sections measured to fit around existing doors and windows. Sections are placed from the wall's base upward, with each section nailed into place and locked to the section beneath it to create a secure barrier against moisture.
