Installing vertical vinyl siding is a smart investment that boosts your home’s curb appeal, enhances energy efficiency, and offers long-lasting protection from the elements. But before the first panel is even nailed in, proper surface preparation is key to a flawless, durable installation.
At Tectum Quality Roofing, we believe in doing things right the first time. Here’s a comprehensive guide to what must be done before installing vertical vinyl siding.
-
Conduct a Thorough Inspection
Before beginning any siding work, it’s essential to inspect the home’s exterior. Look for:
- Rotting or damaged wood
- Mold or mildew growth
- Old siding that needs removal
- Insect infestations
These issues must be resolved before installation to prevent problems down the line.
-
Remove Old Siding
While vertical vinyl siding can sometimes be installed over existing materials, it’s best practice to remove old or damaged siding. This allows for a proper inspection of the sheathing and helps avoid trapping moisture between layers, which can lead to mold and decay.
-
Repair and Replace Sheathing
Any warped, rotten, or damaged wall sheathing should be replaced. The surface must be smooth, level, and secure to ensure your vertical vinyl siding lays flat and attaches properly.
-
Install House Wrap or Vapor Barrier
Moisture control is critical. Installing a house wrap or vapor barrier:
- Protects the home from wind-driven rain
- Reduces drafts and energy loss
- Extends the lifespan of your siding
Be sure it’s properly overlapped, sealed at seams, and taped around windows and doors.

Mark Stud Locations
Before installing vertical vinyl siding, it’s important to locate and mark stud lines. This ensures fasteners are driven into solid framing for maximum holding power and structural integrity.
-
Install Furring Strips (if needed)
If your wall surface is uneven or you’re installing over masonry, furring strips (typically 1×3 or 1×4 lumber) should be installed vertically to create a flat nailing surface for the siding.
For vertical siding, you may also need horizontal furring strips (strapping) to maintain airflow and allow for moisture drainage behind the panels.
-
Flash Openings and Penetrations
Proper flashing around windows, doors, and other openings is essential to direct water away from the structure. Use metal or vinyl flashing along with waterproof tape to protect vulnerable areas.
-
Install Starter Strips and Trim
Before hanging the first panel, starter strips and corner posts should be installed. These components:
- Provide a finished edge for your siding
- Ensure proper alignment
- Help lock panels in place
Precision here sets the stage for a clean, professional look.
Final Thoughts: Why Prep Matters
Vertical vinyl siding delivers great performance, but only if installed over a properly prepared surface. Skipping steps or rushing through prep work can lead to warping, buckling, moisture problems, and warranty issues.
