Duct Sealing Cost Lagos

Leaky ductwork in residential or commercial properties in Lagos frustrates HVAC efficiency, raises electricity bills, and reduces occupant comfort. Understanding the cost to seal air ducts in Lagos is key for property owners and investors seeking to protect asset value and operational performance.

Why Duct Sealing Matters

When ducts have holes, gaps or loose joints:

• Conditioned air escapes before reaching rooms, wasting energy

• HVAC system works harder and wears out faster

• Airflow becomes uneven—some rooms too hot or too cold

• Indoor air quality suffers as unfiltered air enters the system
  Sealing ducts helps restore efficiency, lowers costs and supports property performance.

Key Factors That Influence the Cost

• Extent of duct leakage: more holes/gaps = higher cost

• Accessibility of ductwork: hidden ducts behind ceilings/walls are more expensive to seal

• Condition of ducts: damaged or corroded ducts may need repair or partial replacement before sealing

• Materials used: mastics, foil tapes, specialised sealants cost more

• Labour and environment: Lagos conditions (humidity, power, access) can increase time/cost

• Property size and system complexity: large commercial HAC systems cost more than simple home systems

How Property Owners Should Budget

• Obtain at least two or three quotes from credible HVAC/ductwork firms in Lagos

• Ensure quote details scope: what ducts, what materials, access conditions

• Include a contingency budget +10‑15% for unforeseen issues (e.g., hidden damage)

• Consider the pay‑back: energy savings and improved comfort may make the cost worthwhile

• Combine sealing with other maintenance (filter changes, coil cleaning) for efficiency gains
