Two quotes for the same driveway can look completely different in structure: one sets out a defined scope of work for an agreed sum, the other is priced by time on site with materials on top. Both are legitimate ways to price a job, but they shift risk and responsibility in different directions, and comparing them fairly means looking past the headline approach to what's actually promised.
The goal here isn't to say one is universally better — it's to give you a way of reading either type of quote so you know what you're agreeing to before the van turns up.
What a fixed-scope quote commits both sides to
- A defined list of what's included — area covered, whether biocide treatment is part of it, whether re-sanding or degreasing is covered.
- A defined outcome for that scope, agreed before work starts, so there's no ambiguity about what 'done' looks like.
- Clarity on what would count as extra work outside that scope, and how that would be agreed if it comes up.
What day-rate work commits both sides to
- Time spent on site, generally billed per day or half-day, with the total depending on how the job actually runs.
- Flexibility to respond to problems found during the job — hidden damage, unexpected contamination — without renegotiating a fixed scope.
- A greater reliance on trust and clear communication about progress, since the final commitment isn't locked in from the outset.
Questions that matter more than the total figure
- Does the quote specify whether biocide treatment and re-sanding are included, or are they separate?
- If day-rate, is there an estimated range of days, and what happens if the job runs long?
- If fixed-scope, what triggers extra cost — is it defined clearly, or vague?
- Who decides if unexpected work is needed once the job is under way, and how is that agreed before it happens?
Where each approach tends to suit the job better
A clearly defined, standard job — a driveway of known size and material — suits a fixed scope well, because the variables are largely known upfront. A job with genuine unknowns, such as extensive hidden jointing repair or a mixed-material property where the full extent of work only becomes clear on site, can suit day-rate pricing better, provided the communication around it is clear as the job progresses.
