Skylight Drafts & Air Leak Repair

Stop Unwanted Drafts, Cold Spots & Air Infiltration Around Your Skylight

A skylight should bring natural light — not cold air, wind noise, or uncomfortable temperature changes.
Drafts around a skylight almost always indicate a problem with:

• failed or aged weatherstripping

• improper installation

• gaps between the skylight frame and shaft

• deteriorated flashing

• warped or cracked domes

• poor insulation around the skylight shaft

Our team diagnoses and repairs every type of skylight air leak to restore comfort, energy efficiency, and proper sealing.

Common Causes of Skylight Air Leaks

We inspect all possible sources of air infiltration, including:

• Failed Gaskets & Weatherstripping
Rubber seals lose elasticity over time, creating gaps where cold air enters.

• Improper Installation or Outdated Mounting Methods
Older skylights often lack modern sealing systems and rely on outdated materials that no longer protect the edges.

• Gaps in the Drywall or Skylight Shaft
Poor insulation or drywall separation inside the shaft can cause significant drafts even if the skylight itself is fine.

• Damaged or Aged Flashing
If exterior flashing shifts, loosens, or corrodes, air penetrates through the roof opening.

• Cracked Acrylic Domes
A small crack in a plastic dome instantly causes airflow and temperature imbalance.

How We Fix Skylight Drafts & Air Leaks

1. Full diagnostic inspection—interior + exterior
We locate exactly where the air is entering.

2. Resealing or replacing gaskets & weatherstripping
High-quality VELUX-grade perimeter seals.

3. Flashing system reconstruction (if needed)
Ensuring the exterior barrier is tight and wind-proof.

4. Insulation upgrade in the skylight shaft
Stops hidden air leaks behind the drywall.

5. Replacement of cracked domes or outdated skylights
Modern glass units dramatically improve comfort.

6. Optional upgrade to energy-efficient glazing
We can replace old plastic with insulated Low-E / Argon glass.

When to Consider a Full Skylight Replacement

Drafts often indicate that the skylight is at the end of its lifecycle.
Replacement is recommended if:

• your skylight is 15+ years old

• it has an acrylic dome

• seals are deteriorated beyond repair

• you want better temperature control

• you want noise, heat and UV reduction

VELUX glass skylights offer superior sealing and insulation, especially compared to old acrylic domes.
