Estimating & Glazing Quote Software for Glaziers

A glazing takeoff is the measured area of every glazed item on the plans, in square metres, broken down so each type can be priced against its own rate. A complete glazing job usually mixes several of the following, and each one needs its own line rather than being averaged into a single “glazing” quantity.

• Windows and doors — standard openings, usually the bulk of a residential job.
• Shopfronts and commercial glazing — larger panels, often structural or feature glass.
• Balustrades — frameless or semi-frameless glass panels with their own fixing and safety requirements.
• Splashbacks — kitchen and bathroom glass, usually toughened, cut to a tight tolerance.
• Mirrors — supplied and installed in a similar way to glass, but priced on a different rate.

Two openings of the same size can carry very different prices once glass specification is factored in. Thickness, toughening, laminating and whether the unit is a double-glazed IGU (insulated glass unit) all shift the rate per square metre, and each needs to be selected and applied consistently across a quote rather than eyeballed opening by opening.

IGUs add a second variable on top of the base glass type — the cavity width and the make-up of each pane — so a rates library that only stores one “glass” rate will under-price or over-price double-glazed jobs against single glazing.

• Float, toughened and laminated glass at different thicknesses (for example 4mm, 6.38mm, 10mm).
• Single glazing versus double-glazed IGUs, including cavity width and spacer make-up.
• Safety glazing requirements for specific locations — doors, low-level glazing, wet areas.
• Tinted, obscure, Low-E and acoustic glass options.

Aluminium or timber framing, tracks, locks, handles and other hardware are typically priced as their own line items rather than folded into a blended glazing rate. That keeps the quote transparent and lets a frameless glass job — a balustrade or splashback — be priced differently from a fully framed window or door, even on the same tender.

Installation labour changes with access and height as much as it changes with panel size. A ground-floor window replacement is a different labour cost to a second-storey shopfront panel that needs scaffolding, an elevated work platform or a glass lifter, and that difference needs to be priced explicitly rather than absorbed into an average labour rate.

• Framing profile and finish — powder-coated, anodised, timber.
• Door and window hardware — hinges, locks, handles, tracks, rollers.
• Fixings and brackets for frameless balustrades and splashbacks.
• Access — ground floor versus upper floor, scaffolding, EWP or glass lifter hire, and crew size for larger panels.

Once glazed areas are measured and glass types are assigned, pricing a glazing job means applying a glass rate per square metre by type and thickness, a separate framing and hardware rate, and a labour rate adjusted for access, then adding overheads and margin on top.

The worked example below shows how a small shopfront glazing quote comes together once area, glass, framing and labour are broken into separate lines rather than one blended rate. The rates shown are examples only, not My Trade Hub pricing guidance — every glazier applies their own rates in their own rates library.

A PDF plan takeoff is the fast way to get an early, priced number for a tender or a quote — measuring glazed openings straight off the drawings instead of scaling them by hand. It is genuinely useful for tendering, budgeting and comparing options before a job is won, but it is not a replacement for the site measure.

Glass also breaks. Cut-to-size panels do not always survive transport, handling or a tight install, so a wastage and breakage allowance needs to sit on top of the measured area — not be absorbed silently into the margin — adjusted up for larger or more fragile panels such as frameless balustrades or oversized shopfront glass.
