If water appears after a new installation, do not panic. Here is what to do.
Step 1: Document it
Take photos and videos of the leak, note the date, the weather and which window. Place towels and move belongings.
Step 2: Call your installer
Contact your contractor quickly. A good installer will schedule an inspection. Keep the contract and warranty handy.
Common causes
- Sealant gaps around the frame.
- Flashing problems at the sill or head.
- Blocked weep holes that prevent drainage. See maintenance tips.
- Stucco or wall cracks near the window.
- Wind-driven rain finding a small gap.
Step 3: Get it fixed in writing
Ask what the cause is and what the repair will be. Keep written records of the visit.
Prevention
Hire a licensed installer with proven work and a workmanship warranty. See how to choose a contractor and the installation process. If your leak is on an older window, see why windows leak when it rains.
How a leak investigation works
A good installer will look at the window, the exterior sealant and the surrounding wall. A simple water test can help: a hose is run on one area at a time (starting low and working up) while someone inside watches for water. This often pinpoints the leak path without guessing.
Typical fixes
- Re-sealing joints and cracks.
- Clearing or adding weep paths.
- Repairing flashing or stucco around the window.
- Replacing a defective gasket or glass unit under warranty.
Protecting your home meanwhile
- Wipe up water promptly to avoid damage to floors and drywall.
- Place towels or a bucket where needed.
- Take dated photos of any stains or damage.
Warranty basics
Know which warranty applies: the manufacturer covers product defects, and the installer typically covers workmanship. Send your claim in writing, keep copies, and ask for timelines.
When to escalate
If problems persist and your contractor is not responding, document everything and consider contacting the licensing board or seeking legal advice. Most reputable contractors resolve leaks quickly.
