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 LEIAB Windows installation.

1. 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 timber 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. 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.

3. 3

   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 Leiab timber 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. 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. 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 Leiab 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. 6

   Frame wipe and hardware check

   On Leiab timber frames: use a barely damp cloth and dry immediately. Never allow water to sit on timber joints or frame corners -- moisture causes swelling and paint failure.

   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

• ★ Never use solvents on the aluminium exterior - the powder coat carries a 25-year guarantee and solvents damage it permanently.
• ★ The wax removal step on new windows is easy to miss - skip it and you smear the protective coating across the glass rather than removing it.
• ★ Use separate cloths for aluminium and timber surfaces to avoid carrying aluminium grit onto the timber or timber residue onto the powder coat.
• ★ Silicone spray for hardware lubrication, nothing heavier - aggressive lubricants attract dirt and cause mechanisms to gum up over time.
• ★ The 50-year rot warranty is real but it is conditional on care. Keep records of your annual lubrication and cleaning routine.

What NOT To Do

Bundle Kits and Tool Recommendations

Cleaning Frequency

Glass: 2x per year minimum (Inside and out.). Aluminium exterior frames: Once per year minimum (With window cleaner and cloth or chamois.). Urban or coastal locations: 4x per year (Quarterly cleaning recommended.). Hardware lubrication: 1-2 times per year (Hinges, locking points, lock mechanism holes.). Coupling hooks (2+1 systems): Once per year. Seal inspection: Once per year (Or after heavy storms.)

Field Notes

“Glass: minimum twice per year inside and out. Aluminium exterior frames: minimum once per year with window cleaner and cloth or chamois. Urban or coastal environments with high pollution or salt air: quarterly cleaning recommended. Hardware lubrication (hinges, locking points, lock mechanism holes): 1-2 times per year. Coupling hook lubrication on 2+1 systems: once per year. Seal and weatherstripping inspection: once per year, or after heavy storms.”
