Fortrex Charleston operates as a specialized siding replacement contractor, delivering full siding replacement as a system-level reconstruction, not simply removing and installing new panels.
Siding is a core component of the building envelope, responsible for:
When siding fails, the issue is not just visible deterioration, it is a breakdown in how the wall system manages moisture and airflow
Siding failure develops progressively and often remains hidden behind the surface.
Failure progression:
Moisture does not move only downward.
At this stage:
There is a clear threshold where repair no longer restores system performance.
Escalation pattern:
Siding replacement is required when the entire cladding system loses its ability to protect and regulate the building envelope.
Key distinctions:
Conditions that indicate siding replacement:
Siding replacement is the most efficient solution when the system can no longer be stabilized.
Siding replacement is executed as a complete system reconstruction process, ensuring proper moisture flow, airflow, and structural protection.
Inspection of siding, insulation, and framing condition
Tear-off of panels, trim, and compromised materials
Correction of damaged sheathing or framing
Creation of a controlled drainage plane
Improving thermal performance
Installing panels with proper spacing and alignment
Reinforcing all transitions and openings
Allowing controlled drying behind the siding
Verifying full system performance
Airflow is a critical but often overlooked component.
How proper airflow protects the system:
If airflow is blocked:
| Method | When It Is Used |
|---|---|
| Full System Replacement | When failure is widespread |
Sectional Replacement | When damage is extensive but localized |
| Structural Repair Integration | When framing is compromised |
Insulated Siding System | When energy efficiency is prioritized |
| Fiber Cement Installation | When durability is required |
| Incorrect Replacement | Correct Replacement |
|---|---|
| Installing over damaged substrate | Removing and repairing underlying structure |
| Ignoring moisture damage | Identifying and correcting water intrusion |
| No drainage plane | Installing proper moisture barrier |
| Blocking airflow | Allowing drying through ventilation |
| Improper spacing | Allowing expansion and contraction |
Siding replacement cost depends on system complexity, materials, and structural condition.
| Scope / Complexity | Price Range |
|---|---|
| Basic vinyl siding replacement | $8,000 – $15,000 |
| Mid-range fiber cement siding | $15,000 – $25,000 |
| High-end custom siding systems | $25,000 – $50,000+ |
Siding replacement is a long-term investment in the building envelope.
| Service | Objective | When It Works |
|---|---|---|
| Siding Repair | Fix localized damage | When system is intact |
| Siding Replacement | Rebuild full system | When system has failed |
| Siding Installation | Build new system | New construction |
Siding replacement must meet strict construction standards.
Every project is executed with controlled risk and technical accuracy.
