Brand at a Glance
- Owned by Asian Paints - India's largest paint company and a dominant home-improvement brand
- 20-year warranty is a market differentiator in India where warranty support is often weak
- German-engineered profile technology positioned at premium residential buyers
Product Range
- uPVC casement and sliding windows (German profile-engineered systems)
- uPVC tilt-and-turn windows
- Aluminium sliding and casement windows
- uPVC and aluminium door systems
Why This System
Asian Paints backing means Weatherseal has the distribution network and consumer trust of an established national brand. The 20-year warranty creates accountability that most Indian window companies avoid. For cleaners, it means clients may be more invested in maintaining the product properly.
Weatherseal uPVC profiles use German-engineered formulations with good UV stabiliser packages - better than many Indian-manufactured uPVC profiles. However, Mumbai's coastal salt air, high humidity, and UV still degrade seals and hardware over time. Aluminium systems on sea-facing Mumbai apartments need particular attention to corrosion at frame joints.

Step 2 of 2: The Orloffs Protocol
The Orloffs Protocol
Since 1999 I've cleaned hundreds, if not thousands, of different window brands and systems. The physics of clean glass don't change from one brand to the next. Follow the steps below and you'll clean your Weatherseal windows to a professional standard โ guaranteed.
Pro Tools
My daily tool list. This is what I carry to every job.
Follow these steps in order. Each one builds on the last. This is the same sequence I use on every Weatherseal installation.
- 1
Preparation -- before any water touches the glass
Fill the bucket with at least 10 litres of water. Add soap for cleaning power -- enough to cut through environmental deposits, not so much you are fighting foam.
Before touching the glass, brush down the surface to remove loose dust, spiderwebs, and debris. Any grit left on the glass during the wash phase risks scratching during agitation.
Check the aluminium frame condition before you start. Confirm which cleaning product is safe for that surface before opening any bottle.
Cover anything below the windows that cannot be moved.
- 2
Agitation -- apply and work the solution
Dip the microfiber T-bar completely into the soap water, both sides. Remove excess water with your hand so it does not drip. Apply the solution across the entire glass surface with overlapping passes.
The goal is to fully dissolve and release every deposit from the glass surface. Anything not released during agitation gets transported across the glass by the squeegee as a smear.
For stubborn spots -- insect marks, salt residue, environmental deposits -- re-apply soap water and allow it to soak for a full minute before agitating again. Use more soap water, not more pressure.
For panels above arm reach: attach the T-bar to an extension pole. Work in sections -- top first, then middle, then bottom -- keeping each section wet until you squeegee it.
Rinse the T-bar cover regularly during the job. A dirty applicator causes microscopic scratches that accumulate over time.

Detail the frame edge before squeegeeing
Use your 100% cotton towelling rag, finger pressed into the fabric, to work into every junction and remove pooled soap water before the squeegee pass.
This prevents drips running down onto already-cleaned areas during squeegeeing and keeps soap water out of drainage channels.
On Weatherseal aluminium frames, pay particular attention to the bottom edge where glass meets the frame sill -- water pooled here runs into drainage openings and leaves residue over time.
- 4
The squeegee
Tilt the squeegee at a slight angle so soap water spills from one side of the channel only -- not both. If the rubber is jumping or squeaking, either the rubber is not lubricated enough or the glass surface has warmed.
Cutting in: start with the rubber blade making first contact on a dry edge of the glass.
Side to side: horizontal passes across the panel. Works well on wide sections. Top to bottom: vertical passes down the panel. Works well on tall narrow sections.
The J tune: one smooth unbroken motion top to bottom, wrist rotating at each end to reverse without lifting the rubber. The most efficient method on larger panels -- but it requires training before applying it to premium glass.
Wipe the rubber dry after every pass. Overlap each stroke by 2-3 cm.
- 5
Final edge detailing
After squeegeeing, there is always a residual line of water along the bottom edge and at the panel sides. Take a dry cotton rag, fold to a clean corner, and detail these edges in one smooth pass.
On Weatherseal frames, the bottom edge where glass meets the sill requires the most careful attention. Water left here runs into drainage and leaves residue that affects the next clean.
Rotate the rag to a clean section after every pass. If the rag picks up grit at any point, replace it immediately.
- 6
Frame wipe and hardware check
On Weatherseal powder-coated aluminium frames: use pH-neutral cleaner only, never abrasive pads or steel wool. Dry immediately after wiping.
Check that all drainage openings are clear and unobstructed. Water must be able to flow freely -- a blocked channel leads to accumulation that affects seal performance over time.
Operate every opening window through its full range. Stiff handles or resistance at locking points indicate hardware that needs lubrication. Flag it to the owner rather than forcing it.
Pro Tips
- Mumbai sea-facing installations: clear weep holes on every visit - salt-air corrosion begins at drainage points.
- Weatherseal aluminium frames on upper floors face high UV and salt loading - check gasket condition on each clean.
- Tilt-and-turn mechanisms need PTFE lubrication every 12 months in Mumbai humidity.
What NOT To Do
- Do not use solvent-based cleaners near the gasket seals - degrades rubber in humid conditions.
- Do not ignore weep hole blockage - standing water in Mumbai humidity promotes mould inside frames.
- Do not use abrasive products on the German-profile uPVC surface - harder to source replacements if profiles are damaged.

Cleaning Frequency
Every 6-8 weeks inland; monthly on coastal Mumbai installations. Monsoon post-clean is critical.
Frequently Asked Questions
Field Notes
โWeatherseal installs are typically in premium residential complexes where clients notice quality. Present the service professionally. Mumbai sea-facing apartments above the 10th floor are exposed to wind-driven salt spray - the frames look clean but carry invisible salt deposits. Always include a thorough frame rinse, not just glass cleaning.โ
