A leaking skylight is almost always a flashing or seal problem, not a bad skylight itself — our Skylight Repair crews diagnose it correctly before touching anything.
We stock common skylight brands' replacement seals and hardware, keeping most Skylight Repair repairs to a single visit.
We also check the surrounding shingles and decking while we're up there, since a skylight issue sometimes points to a broader roof concern.
Every Skylight Repair technician carries current Castro Valley, CA licensing and skylight-specific training.
Local Castro Valley dispatch means most Skylight Repair calls get scheduled within a few days.
Flashing, seal, and replacement costs are quoted separately, not bundled together.
Moisture meters help confirm whether a leak is active or residual before recommending a fix.
Here's what falls under our Castro Valley Skylight Repair service for skylights.
Cracked or corroded flashing around the skylight curb is the most common source of Castro Valley skylight leaks.
Seal replacement is often a faster, cheaper fix than homeowners expect before calling.
Fogging or dripping isn't always a leak — condensation from poor ventilation can mimic leak symptoms.
When the skylight unit itself has failed — cracked glass, fogged double-pane seals — we replace it to current code.
Adding a skylight to a Castro Valley home involves structural and flashing considerations beyond just cutting a hole in the roof.
We check airflow as part of a full Skylight Repair diagnosis, not just the flashing and seals.
