Skylight Maintenance Mistakes and How to Avoid Them
Skylights enhance indoor environments but require regular attention to remain effective. Without proper maintenance, they can become a source of problems, such as leaks or structural damage.

California’s Climate as a Key Maintenance Factor
Homeowners in California face a combination of intense sunlight, variable temperatures, and seasonal precipitation. UV exposure accelerates the wear and tear on seals and plastic glazing elements, while precipitation can clog the drainage system. Given these conditions, regular Velux skylight maintenance is strongly recommended in California cities like Orange and Santa Ana.
Common Mistakes Homeowners Make
Homeowners often make errors that, over time, can lead to serious consequences.
These include:
- using harsh cleaning products that damage the glass
- ignoring cracks or chips
- improper frame installation that compromises sealing
Such issues can lead to premature wear and increased repair costs.
How to Prevent Problems
It is recommended to:
- schedule cleaning and inspection at least once or twice a year
- check hardware and opening mechanisms
- lubricate moving parts and address issues as they arise
Consistent upkeep helps preserve skylight integrity and minimizes the likelihood of system breakdowns.
Step-by-Step Guide to DIY Maintenance
For those who prefer taking care of their skylights themselves, here is a simple routine:
- clean the glass with a soft cloth and a neutral cleaner
- check the condition of seals and replace them if needed
- clear drainage channels of debris and leaves
- lubricate hardware using a silicone-based or manufacturer-recommended lubricant
- check all joints for leaks and reseal if necessary
Doing this regularly will help maintain your skylight’s functionality and avoid unnecessary expenses.

When to Call in the Professionals
If you notice any of the following signs, it is best to contact a trusted skylight company:
- skylights make unusual noises when opening or closing
- there are leaks or condensation between panes
- mechanisms feel unstable or require excessive force to operate.
Even properly installed Velux fixed skylights require scheduled maintenance to perform reliably, especially under California’s shifting weather conditions. Routine servicing helps maintain weatherproofing, thermal efficiency, and smooth mechanical operation. Inspections should be conducted on a regular basis to identify wear before it leads to damage. Consult a certified specialist to evaluate which residential skylight options best suit your property.
