Rotted Siding Repair in Knoxville, TN

Rotted siding is one of the most common problems we see in Knoxville, TN. What looks like a small soft spot or damaged board is often a sign of deeper moisture issues behind the siding.

At MI Homesiding & Roofing, we repair rotted siding by fixing the cause of the problem—not just replacing the damaged area.

Signs of Rotted Siding

Wood rot does not happen overnight. It develops over time as moisture gets trapped behind the siding.

Common signs include:

  • Soft or spongy wood
  • Cracked or deteriorating siding
  • Discoloration or dark spots
  • Paint peeling or bubbling
  • Wood siding rotting at the bottom
  • Mold or mildew

If you notice these signs, the damage may already be affecting the structure behind the siding.

What Causes Wood Rot Behind Siding?

In Knoxville, wood rot is usually caused by moisture intrusion.

Common causes include:

  • Missing or incorrect flashing
  • Water leaking behind siding
  • Poor sealing around windows and doors
  • Improper installation
  • Siding installed too close to the ground
  • Water not draining properly

These issues allow moisture to stay trapped, leading to rot over time.

Rotted Wood Under Siding

In many cases, the damage goes beyond the visible siding.

We often find:

  • Rotted sheathing (OSB or plywood)
  • Damaged framing
  • Mold inside wall cavities
  • Insulation affected by moisture

This is why proper inspection is critical before making repairs.
