FAQs - Skylights and Roof Windows in Greenwich

To clean skylight windows in Greenwich from the inside, first, use a telescoping window cleaning tool or a ladder to reach the glass itself. Next, apply a mixture of mild soap and water or a non-abrasive glass cleaner. Then, gently wipe the surface with a soft, lint-free cloth or squeegee. Finally, harsh chemicals should be avoided to prevent damage to the window surfaces.
A skylight's lifespan in Greenwich can vary depending on several factors, including the materials used, the quality of installation, and the prevailing environmental conditions. Consequently, the average lifespan of a skylight falls between 10 to 20 years. However, regular maintenance and timely repairs can significantly extend its life.
To prevent condensation dripping from your Greenwich skylight:
- Improve ventilation: Increase airflow by opening windows or using extractor fans.
- Reduce humidity: Use a dehumidifier in damp areas.
- Enhance insulation: Improve insulation around the skylight to reduce temperature differences.
- Check for leaks: Seal any gaps or cracks around the skylight.
- Consider double glazing: Upgrade to double-glazed skylights for better insulation.
- Regular cleaning: Wipe away condensation to prevent mold growth.
- Professional help: If the problem persists, consult a specialist.
Generally, you won't need planning permission for a skylight in Greenwich. However, there are exceptions:
- Size: If the skylight is exceptionally large or protrudes significantly above the roofline.
- Location: If your home is in a conservation area or is a listed building.
It's advisable to check with the Royal Borough of Greenwich's planning department for confirmation.
No, a skylight generally doesn't count as a bedroom window in Greenwich or anywhere else in the UK.
To be classified as a bedroom window, it must be openable and provide adequate natural light and ventilation. While skylights can offer natural light, they typically fall short in terms of ventilation and the ability to be opened.
The cost of a skylight installation in Greenwich typically ranges from £500 to £3,000. However, the final price can vary significantly based on factors such as the size and type of skylight, the complexity of your roof, and the installer's experience. It's recommended to obtain quotes from multiple installers to find the best price and service for your specific needs.
