Vinyl siding is a PVC exterior cladding hung loosely on nails over house wrap, so it can move with temperature instead of being fastened tight to the wall.
New siding does more than improve your home's appearance — it protects your biggest investment from Missouri's harsh weather while cutting energy costs. Here's everything you need to know.
Is It Time to Replace Your Siding?
Siding is your home's first line of defense against wind-driven rain, hail, UV radiation, and temperature extremes. Missouri throws all of these at your home in abundance. Watch for these signs that it's time to upgrade:
- Warping, buckling, or cracked panels
- Faded or chalky surface that won't clean up
- Paint peeling on the inside of exterior walls (moisture intrusion)
- Visible rot, especially at corners and around windows
- Higher-than-usual heating and cooling bills
- Hail damage dimpling or cracks after a major storm
- Older aluminum siding that dents and oxidizes
Why Vinyl Siding Is the #1 Choice for St. Louis Homes
Vinyl siding has dominated the residential exterior market for decades, and for good reason. It offers an outstanding combination of durability, low maintenance, curb appeal, and value that no other material matches at its price point.
- Never needs painting — color is molded through the entire panel
- Resistant to rot, insects, and moisture — no wood to decay
- Withstands Missouri temperature extremes without expanding or contracting excessively
- Dramatically lower lifetime maintenance cost vs. wood or aluminum siding
- Available in hundreds of colors and dozens of profiles
- Can be installed over existing siding in many cases, reducing labor and disposal costs
- Modern insulated vinyl siding significantly improves wall R-value

Why does nailing technique matter on vinyl?
Vinyl expands and contracts with temperature, so it must hang, not be pinned. Nails driven too tight cause waves and buckling on hot days. Installers center nails in the slots and leave a small gap under the head. Ask how the crew handles this on south and west walls.
Can vinyl go over old siding?
Sometimes, but only after checking what is under it. Covering rotted wood or wet sheathing hides problems that keep growing. Ask your installer to open a few areas first. Tear-off lets them inspect and repair the wall, then install proper house wrap.
How should you prepare for siding day?
Move grills, furniture and planters away from the walls. Take fragile items off interior walls, since installation can vibrate them. Plan for noise during tear-off. Ask where the dumpster will sit and how nails will be collected from the yard.
- Ask how outlets and lights will be trimmed out
- Confirm house wrap and window flashing are included
- Keep the color and profile name for future repairs
