The Schedule Is the Whole Job

Glazing is priced per unit, not per square metre, and every unit is a different number. A 900 by 1200 awning window in a powder-coated frame and the same opening in double glazing with a low-E coating are two very different costs, and the plan sheet shows them as the same rectangle.

So the window and door schedule does most of the work. We take off every opening by type, size, frame material and glass makeup, then price the framing, hardware, sealing and access around it. Shopfronts, balustrades, shower screens, mirrors and splashbacks are measured the same way, item by item.

What Is in a Glazing Estimate?

A Perth glazing estimate lists every opening as its own priced item: window and door type, size, frame material, glass makeup and hardware. Shopfront and curtain wall framing is measured in linear metres of section and square metres of glazed bay. Frameless work is measured by panel run with the fixing method and set out allowed for. Sealing, flashings and packers are taken off by perimeter length. Access, handling and a breakage allowance sit in the estimate as separate visible lines rather than hidden inside a rate, because on glass they are a real part of the cost.

Frameless Glass Is a Different Trade

A framed window is forgiving. It arrives as a unit, it goes into a rough opening and the reveal covers a few millimetres of error either way.

Frameless glass is the opposite. Every panel is toughened and cut to size before it leaves the factory, so nothing can be trimmed on site, and a spigot set out that is out by ten millimetres means a new panel and a new lead time.

The Lines We Price Separately

  • Panel schedule by size, thickness and edge finish
  • Spigots, channel, clamps and gate hardware by item
  • Core drilling or chemical fixing into the substrate
  • Site measure and set out before the order goes in
  • Handling and lifting gear for panels over a safe two-man lift
  • Certification and compliance for balustrade and pool fencing
  • Breakage and re-order allowance, shown as its own line
  • Silicone, packers and setting blocks by linear metre

We price the work, we do not carry the glass. If you want the panels supplied and fitted as well as priced, a Perth glazier can quote the supply and install, and our estimate gives you an itemised document to check that quote against line by line.

Access Decides the Labour

Glass is heavy, brittle and awkward, and the cost of moving it is decided long before anyone opens a tube of silicone. The same panel is a two-man carry through a wide opening on a slab, or a crane lift and a traffic management plan on a street frontage.

That is why two glazing quotes on the same drawings can be a long way apart. One has priced the panel and one has priced the panel plus the hoist, the licensed lift, the after-hours road closure and the day the crane sits idle waiting on a delivery.

We estimate access as its own scope. Lifting method, restricted-hours work, scaffold or elevated work platform hire and protection of finished surfaces are all visible lines you can price, argue or delete, rather than assumptions buried in a rate per square metre.

Windows, Doors and the Glazing Schedule

On a new home, the window schedule is where the glazing budget is won or lost. Energy efficiency requirements now push a lot of Perth builds toward performance glass, and a schedule that calls up double glazing or a low-E coating on the western elevation carries a very different supply cost to plain float in the same frames.

We take the schedule off exactly as drawn, then flag any opening where the glass makeup is missing, ambiguous or likely to change under the energy report. That way you know which numbers are firm and which ones are sitting on an assumption before you submit a price.

What Changes a Pane Price

  • Glass makeup: float, toughened, laminated or an insulated glass unit
  • Coatings and tints, which change both the supply rate and the lead time
  • Frame material and finish: powder-coated aluminium, timber or composite
  • Opening type: fixed, awning, sliding, bifold or stacker, each with its own hardware
  • Size, because oversize panels leave the standard sheet and standard handling
  • Compliance glazing to wet areas, low-level openings, doors and balustrades

Glazing for the Perth Climate

Perth is hard on glazing. High UV, hot western sun on long summer afternoons and salt-laden air through the coastal suburbs all shorten the life of the wrong specification, and the cheapest schedule at tender is often the one that gets replaced first.

  • Western and northern elevations: solar control coatings or performance glass carry the heat load
  • Coastal sites: marine grade finishes on hardware and framing, or you buy corrosion
  • Pool surrounds: stainless spigots and fixings rated for a chlorinated, wet environment
  • Wet areas and low-level glazing: safety glass to the relevant standard, priced as such
  • Large fixed panels: thickness driven by wind loading, which is a site-specific number
  • Splashbacks behind cooktops: toughened, with cut outs and edges done before delivery

Common Questions

Straight answers on how we price glass and glazing estimating in Perth. If yours is not here, send your plans and just ask.

Windows and doors are counted from the window and door schedule by type, size, frame material and glass makeup, then priced per opening. Shopfront and curtain wall framing is measured in linear metres of section with the glazed bays measured in square metres. Frameless balustrades and pool fencing are measured by panel run with gates counted separately. Sealing and flashings are taken off by perimeter length, and access and breakage allowances are added as their own lines.

Yes. Insulated glass units, low-E coatings, tints and laminated makeups are all priced at current Perth supply rates for the specified product. Where the schedule does not state a makeup, or where the energy report is likely to change it, we price the drawn makeup and flag the opening so you know that line is an assumption.

Yes. Frameless work is measured by panel run and gate count, with the fixing method, core drilling, set out, hardware and certification priced as separate lines. Because frameless panels are toughened and cut to size before delivery and cannot be adjusted on site, we also include a visible breakage and re-order allowance rather than hiding it in a rate.

No. We are estimators, not glaziers, so we produce the priced document and you take it to whoever is doing the work. That separation is the point: an itemised estimate gives you a line by line basis to compare glazing quotes, question a rate or negotiate a variation.
