​Frequently Asked Questions

How do I know if I have a window leak? Common signs include water stains, bubbling paint, musty odors, and moisture or condensation between the window panes or frame.

Is the leak coming from the window or somewhere else? Leaks often appear around windows, but the source could be roofing, stucco, or flashing failure. Our team will conduct a full inspection to identify the exact cause.

Can you repair the leak without replacing the entire window? Yes, in many cases we can reseal, re-flash, or patch the surrounding area without replacing the window. Full replacement is only recommended if the frame is damaged.

How long does a typical repair take? Most window leak repairs are completed in 2–3 days, depending on the severity and location of the damage.

Do you provide a warranty? Absolutely. All of our window leak repairs come with a workmanship warranty. Ask us for details during your free estimate.
