Check the Glass and Existing Frame Too
When a window has an operating or sealing problem, damaged or loose glass can also need attention. Kutbi can assess the existing aluminium or uPVC frame and recommend suitable glass replacement where required.
Find the Cause of Window Water Leakage Before Replacing the Window
Water leakage does not always mean the complete window needs replacement. Kutbi checks the existing aluminium or uPVC window for sealing, gaps, alignment, drainage and related operating issues before recommending suitable repair.
Rubber beading or seal wear
Old, loose or deteriorated sealing can allow water to pass through gaps around the shutter or glass area.
Rubber Beading Replacement →Window gaps
Visible gaps or poor sealing around a window can contribute to water entry and should be assessed before replacement.
Window Gap Sealing →Alignment and closing
A shutter that does not sit or close correctly may leave uneven contact and affect sealing performance.
Alignment Repair →Track and sliding-system condition
For sliding windows, track, wheel and roller condition can affect shutter position and closing.
Track Repair →Aluminium & uPVC Window Leakage Repair
Kutbi can assess water leakage on existing aluminium and uPVC windows and identify whether the likely repair involves sealing, beading, gap sealing, alignment or another compatible component.

Inspection of sealing, sash position, gaps and related operating components on existing uPVC windows.
uPVC Window Repair →Window Water Leakage Repair Process
- Identify where and when water enters.
- Inspect visible seals, beading, gaps and window position.
- Check alignment and relevant sliding-system components where applicable.
- Identify the likely source rather than assuming the complete window needs replacement.
- Carry out suitable sealing, adjustment, beading or compatible component repair.
- Check the window's closing and sealing condition after the work.
Repair First — Replace Only When Necessary
A leaking window may be repairable even when the problem looks serious. Kutbi follows a repair-first approach and considers the condition of the existing system before recommending larger replacement work.

Window Water Leakage Repair in Bangalore: Common Causes
Window water leakage can come from worn rubber beading, gaps, poor closing, alignment problems or conditions around the sliding system. Kutbi checks the existing aluminium or uPVC window before recommending suitable repair work.
Water Coming Through Window Gaps
Visible gaps around a closed window can allow rainwater to enter and should be assessed before simply adding sealant.
Window Gap Sealing →Worn Window Rubber Beading
Hardened, loose or damaged beading can reduce the seal around the glass or shutter.
Rubber Beading Replacement →Window Alignment & Closing
An incorrectly positioned shutter may leave sealing gaps and affect how the window closes.
Window Alignment Repair →Sliding Window Track Problem
Track condition and related sliding-system problems can affect shutter position and operation.
Window Track Repair →Window Not Closing Properly
If the shutter does not reach its correct closed position, leakage can become easier during rain.
Window Not Closing Repair →Aluminium & uPVC Windows
Kutbi assesses water-leakage problems on suitable aluminium and uPVC window systems.

- Rainwater enters around the window frame or shutter.
- Water appears near the bottom or side of a sliding window.
- Rubber beading looks hardened, loose or damaged.
- A visible gap remains after the window is closed.
- The shutter does not close or align evenly.
- Water leakage returns after temporary sealing.
The visible leak is not always the actual cause. Checking the window's closing, alignment, seals and sliding components helps identify the appropriate repair.
Window Water Leakage Repair Process
- Identify where and when water enters the window.
- Inspect the shutter, frame and visible gaps.
- Check rubber beading and sealing condition.

- Carry out suitable repair, adjustment, beading replacement or related work and test the window.
Window Water Leakage Repair FAQs
Why is rainwater coming through my window?
Possible causes include worn seals or beading, gaps, poor closing, alignment issues and sliding-system conditions. The actual cause needs to be assessed.
Can rubber beading cause water leakage?
Yes. Deteriorated or loose beading can reduce sealing around the window system.
Can a sliding window be repaired if it leaks?
Suitable existing sliding windows can be assessed for the source of leakage and related operating problems.
Should I just apply sealant?
Sealant may not address the underlying problem if the window is misaligned, not closing correctly or has worn components.
Can water leakage happen with aluminium windows?
Yes. Aluminium window leakage can be related to sealing, gaps, alignment and operating conditions.
Can I send a photo first?
Yes. A clear photo of the complete window and the area where water enters can help with an initial assessment.
