Step 1 
In order for the vinyl siding to be 
installed properly in a level  
fashion, the starter strip at the 
bottom of the wall must be level.
Step 2 
The starting chalk line should be 
located so that it represents the 
top, not the bottom, of the starter 
strip.
Chalk lines are normally 
established from the lowest corner 
of the house. In situations where 
the ground at the corner of the 
house is not level, chalk lines 
must be measured from the soffit 
location to assure a uniform panel 
at the top of the walls. 
Step 3
Attach a chalkline: go to the next 
corner and pull the line taut.
Step 4
Snap the chalkline and repeat the 
procedure around the entire house.
Step 5
Using the chalkline as a guide, 
install the top edge of the starter 
strip along the bottom of the 
chalkline, nailing at 10˝ intervals. 
Allow space for accessories 
(corner posts, J-Channels, etc.)
Step 6
Keep the ends of starter strips at 
least 1/4˝ apart to allow for  
expansion (Fig. 1).
Step 7
Nail in the center of the starter 
strip nailing slots.
Step 8
Starter strip fasteners should be 
driven just flush in the center 
of the slots to take out starter 
looseness, but should not be 
overdriven to where it indents the 
starter.
Before the vinyl siding itself can be installed, a number of accessories 
must be installed first, including starter strips, corner posts, window 
flashing, trim and J-Channels.
