For one accessible balcony deck, start with a defined scope and measurement basis. Measure deck area, threshold height, upstands, edge length and drainage outlet. Specify the membrane or coating system and edge profiles separately. Price the listed tasks separately and state the condition that would require a revision: Hidden substrate rot or inadequate fall requires a revised build-up. The Newcastle, New South Wales worked example checks 7 AUD cost lines and a A$9,398.45 fictional subtotal against the measured scope. Review the matching PDF before making your own quote.

THE ESTIMATING ANSWER

For one accessible balcony deck, start with a defined scope and measurement basis. Measure deck area, threshold height, upstands, edge length and drainage outlet. Specify the membrane or coating system and edge profiles separately. Price the listed tasks separately and state the condition that would require a revision: Hidden substrate rot or inadequate fall requires a revised build-up.

This guide follows one accessible balcony deck in Newcastle, New South Wales . The matching itemised estimate and PDF (https://quicklyestimates.com/en-au/samples/balcony-waterproofing-estimate/) show how the job brief becomes measured quantities and separate AUD amounts. The responsible role in this scenario is roofing contractor. Check the actual site, selected products, supplier figures and labour plan before issuing a client quote.

1. Define the measured job

Renew the waterproof surface system on one small accessible balcony, including edge and outlet details on a sound substrate. Measure deck area, threshold height, upstands, edge length and drainage outlet. Record the measurements and existing condition in the estimate before turning quantities into line items. The scope should make clear why this is a separate project from a broader renovation or maintenance quote.

Measure for this job: Measure deck area, threshold height, upstands, edge length and drainage outlet. Put that measured basis beside the relevant PDF lines so area, fitted length and product purchase quantities stay distinct.

2. Build a product and labour schedule

Specify the membrane or coating system and edge profiles separately. This example has 7 distinct lines, including access and weather protection, existing finish removal, substrate preparation. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.

Choose before pricing: Specify the membrane or coating system and edge profiles separately. The fixture separates access and weather protection, existing finish removal and substrate preparation rather than hiding all work in one figure.

3. Sequence the work and handoffs

Remove existing finish, inspect substrate and confirm drainage fall before applying the new system. Show which task depends on access, a selected product or another trade. If that dependency is still open, label the price preliminary and identify the information needed before a firm quote.

Plan the handoffs: Remove existing finish, inspect substrate and confirm drainage fall before applying the new system. Note which stage needs access, a selected product or another trade before the next stage can be priced confidently.

4. Set a change boundary

Hidden substrate rot or inadequate fall requires a revised build-up. The example excludes structural deck replacement, new balustrade or interior damage repair. Record the discovery, agree the revised work and update the estimate before adding it to the job.

Change trigger: Hidden substrate rot or inadequate fall requires a revised build-up. Record the revised task and quantity before it changes the amount your client sees.

Review the Australian job

Verify the existing water and waste connections, access and selected fittings on site. Assign any specialist work and check approval requirements that apply to the actual address.

The existing finish removal line uses 11.15 m². Keep the site measurement and supplier's selling unit together; a material purchase allowance can differ from installed coverage. The amounts are fictional AUD inputs, not current prices for Newcastle, New South Wales or another location.

Worked project calculation

The paired PDF has 7 cost lines. For example, Existing finish removal is 11.15 m² × A$98.40 = A$1,097.16; Substrate preparation is 11.15 m² × A$84.20 = A$938.83. Each amount comes from the stated quantity and unit rate, so you can trace the arithmetic back to the job scope.

Balcony waterproofing renewal example — AUD, fictional inputs Work item | Quantity | Unit rate | Amount |

Access and weather protection | 1 job | A$430.65 | A$430.65 |

Existing finish removal | 11.15 m² | A$98.40 | A$1,097.16 |

Substrate preparation | 11.15 m² | A$84.20 | A$938.83 |

Waterproof system allowance | 12.08 m² | A$210.75 | A$2,545.86 |

Application labour | 11.15 m² | A$281.00 | A$3,133.15 |

Edge and outlet detailing | 1 job | A$978.75 | A$978.75 |

Final inspection and cleanup | 1 job | A$274.05 | A$274.05 |

Illustrative total | A$9,398.45 |

Adding every exact-cent line gives A$9,398.45 . The PDF uses a 0% tax input only to make its fictional arithmetic visible. Confirm the GST treatment that applies to the actual job and set your own markup before sharing a client quote. A fictional rate is a document input, not a market quote or a recommended selling price.

Scope and pricing boundaries

Renew the waterproof surface system on one small accessible balcony, including edge and outlet details on a sound substrate.

Outside this example: No structural deck replacement, new balustrade or interior damage repair.

Separate product allowances, supply, installation, disposal and any specialist work where the actual project needs them. If access or a hidden condition changes, document the affected scope and agree a revised price instead of silently extending the base amount.
