A client asks what it would cost to refurbish a room. You write “renovation: €4,000”. The total may be right, but it leaves questions that will return during the job: does it cover waste removal? Who buys the flooring? Does painting include the ceiling? A useful construction quote explains what you will deliver and the assumptions behind the price.
Start with the intended result and the conditions you have checked. The figures below are invented to illustrate the method; they are neither a price list nor average market rates. Tax treatment, safety and technical documentation need to be checked for the particular job.
Before listing items, identify the job and recipient
Include the supplier, client, work location, date and a recognisable reference. “First-floor bedroom, revision 2” is more useful than “client work”. State whether the quote follows a site visit or information received remotely. A measurement given over the phone is less reliable than a measured surface.
If the client has not chosen a finish, state your assumption: material type, product range or item awaiting confirmation. Do not silently include a choice that will change. Record access, floor level, lift availability and storage space: these can affect labour and transport.
Describe work that can be checked
Break the job into understandable stages: protection, removal, preparation, supply, installation and finishing. Each item should say what you will do, where, its unit and quantity. “Prepare and paint bedroom walls, two coats, 40 m²” is clearer than “complete painting”.
A small offer does not need a specification running to dozens of pages. Include details that affect the client's choice or your costs. If materials and installation are grouped together, say both are included. If the client supplies materials, state their required characteristics and when they must be available.
- Surfaces: explain how they are measured and which areas are covered.
- Components: give quantities, dimensions and relevant characteristics.
- Hours: clarify whether these are an estimate or an offered quantity.
- Lump-sum work: describe the scope covered by the overall price.
Quantities, unit prices and total: an example
Imagine an internal job with surfaces already measured. You could list the following illustrative amounts, before any applicable taxes:
- Protect furniture and flooring: 1 job × €120 = €120.
- Remove existing skirting boards: 20 m × €5 = €100.
- Prepare and paint walls: 40 m² × €18 = €720, including standard materials.
- Supply and fit skirting boards: 20 m × €14 = €280.
- Transport for this job: 1 × €80 = €80.
The subtotal is €1,300. Do not add paint and application hours again if the €18 per square metre already includes them. If you separate labour, rewrite material and installation prices consistently: changing the presentation must not double-count costs.
Materials and labour: how much detail is useful?
Separate them when the client can choose another supply, buy products directly or omit a service. For standard work you can offer a complete item, provided its content is clear. Separating commercial lines does not require you to disclose your purchase costs or internal margin.
A window retailer, for example, might separate the product, removal, installation and finishing around the opening. A contractor selling a complete job may group some tasks. In either case, the client should understand which conditions change the price.
Write down exclusions, timing and validity
“Extra work excluded” is too vague if you already know what could arise. Specify, for example, repairs to concealed areas, moving services or materials chosen later. Explain how these will be assessed: another visit, a new offer or confirmation before execution. Do not promise that every unexpected issue is always the client's responsibility.
Separate estimated duration from availability to start. “Three working days after materials arrive and the schedule is confirmed” differs from “starting Monday”. Price validity and the work date are separate facts. Also state the agreed payment terms without confusing them with acceptance.
Read it again before sending
Check that quantities and units match the measurements, materials appear only once and the total can be explained from the lines. Open the PDF on a phone too. If an item needs a call to explain it, rewrite it first. When a change arrives, identify the new version and keep the one already shared.
From the site visit to outstanding choices
Prepare a short internal matrix with three columns: information, source and decision. For area, write “measured on site, confirmed”. For material, “client request, model to choose”. For transport, “access checked, one trip expected”. This prevents every line being treated as equally certain.
When material is undecided, distinguish defined work from supply awaiting confirmation. Do not include a generic product in the total and replace it without notice. You can offer two recognisable configurations: the same installation with different materials, checking whether the product change also affects the work.
For example, a different flooring format can change cutting, waste allowance and installation time. Presenting the variation solely as a purchase-price difference would be incomplete. Follow dependencies between items, even when the client thinks the change is small.
For a job involving several suppliers, clarify who covers each task. If an electrician cuts the channels and another contractor repairs them, both quotes should define understandable scopes. The client should not discover a missing task only after work begins.
For a complex offer, attach a summary of choices and refer to it in the text. Use a date or version: “as per attached choices” is ambiguous when several lists exist. Prepare technical documents with suitable tools and manage them separately from the commercial PDF.
The final review concerns more than the total. Check that each requested outcome has an item or clear exclusion, each quantity has a source and every important condition is communicated. This reduces uncertainty more than a long collection of generic clauses.
