Do Skylights Need to be Resealed?

The Function and Purpose of Skylights

Skylights have become increasingly popular in many Auckland homes. They provide natural light, reduce the need for artificial lighting, and can even offer an excellent view of the starry skies at night. But like all fixtures, they require maintenance to ensure they remain functional and continue to provide the benefits they were installed for.

Sealing: A Key Aspect of Skylight Maintenance

One crucial part of skylight maintenance is ensuring it remains sealed. The seal prevents water ingress and ensures the skylight is airtight, contributing to the energy efficiency of a home.

Environmental Considerations

From an environmental perspective, a well-sealed skylight can play a part in ensuring a house remains energy efficient. Gaps or cracks in the seal can lead to unwanted drafts or, worse, rainwater leaking in. This not only affects the indoor climate but could also lead to increased use of heating or cooling systems, impacting both the environment and electricity bills.

When Resealing is Necessary

Skylights, like other home installations, undergo wear and tear. Factors like extreme weather conditions, age, and the quality of the original sealant can determine the frequency of resealing.

Skylight Types and Costs

Different skylight designs come with varying costs and potential sealing issues:

  • Fixed Skylights: These are stationary, providing light but no ventilation. Cost: NZD $290-$730.
  • Ventilated Skylights: They can be opened, offering ventilation. More complex mechanisms mean potentially more areas to monitor for sealing issues. Cost: NZD $580-$1,740.
  • Tubular Skylights: Compact and great for smaller spaces. Cost: NZD $290-$580.

Health, Safety, and Auckland Bylaws

Auckland has specific health and safety regulations related to installations in homes. When considering installing or maintaining skylights, it’s essential to ensure all work complies with local guidelines to prevent accidents or future legal complications. One suburb, in particular, Parnell, has specific bylaws concerning the types and specifications of skylights that can be installed due to the unique architectural history of the area.

Common Mistakes

While resealing is a common maintenance task, errors can occur. Here are some pitfalls to avoid:

  • Using the wrong sealant: Not every sealant is suitable for skylights, especially when considering the material of the skylight frame.
  • Incomplete cleaning: Before resealing, the skylight surface needs to be clean to ensure the sealant adheres correctly.
  • Oversealing: Using excessive sealant won’t necessarily make the seal better. Instead, it can create a messy appearance and even cause functional issues.
