Step-by-Step Guide on How to Install Plastic Siding
Step 1: Prepare the Surface
A smooth and well-prepared surface is key to a successful installation.
- Remove any old siding, nails, or debris.
- Inspect the wall for damage and repair any holes or cracks.
- Install a weather-resistant barrier (house wrap) to protect against moisture.
- Secure insulation panels if extra thermal protection is needed.
Step 2: Install the Starter Strip
The starter strip ensures the first row of siding is level and secure.
- Measure and mark a level chalk line around the base of the house.
- Attach the starter strip along the marked line, keeping it straight.
- Leave a ¼-inch gap between strips to allow for expansion.
Step 3: Install Corner Posts and J-Channels
These components provide a clean finish and secure the siding panels.
- Attach corner posts at each exterior corner, ensuring they extend ½ inch below the starter strip.
- Secure J-channel pieces around windows, doors, and roof edges.
- Leave space for the siding to expand and contract with temperature changes.
Step 4: Install the First Row of Siding
Now it’s time to attach the main panels.
- Begin with the bottom row, locking it into the starter strip.
- Nail the siding loosely in the center of the nail slots to allow for movement.
- Maintain a ¼-inch gap at the ends to accommodate expansion.
Step 5: Continue Installing the Siding Panels
Work your way up while keeping everything aligned.
- Overlap each new panel by at least 1 inch to prevent gaps.
- Ensure all panels are snapped tightly into the row below.
- Avoid nailing too tightly, which can restrict movement and cause warping.
- Check alignment frequently with a level.
Step 6: Cut Panels for Windows and Doors
Custom cuts ensure a seamless look around openings.
- Measure the area carefully before cutting.
- Use a circular saw or snips to trim the panels.
- Fit the panels into the pre-installed J-channels.
Step 7: Install the Final Row and Trim Pieces
Finish the installation with precision.
- Cut the last row to fit under the soffit or roofline.
- Secure the panels without forcing them into place.
- Attach fascia and finishing trim for a polished look.
Maintenance Tips for Plastic Siding
- Clean Annually: Use mild soap and a garden hose to remove dirt.
- Inspect for Damage: Check for cracks or loose panels after extreme weather.
- Avoid Direct Heat: Keep grills or heat sources away to prevent warping.
