Why do paving jobs go wrong before they start?
Many disappointing paving jobs are decided at the hiring stage, not on site. The contractor and the owner had different pictures in mind, nobody wrote the differences down, and the gap only became visible once concrete had set or blocks were laid. Distance makes this worse: owners who spend part of the year in another country rely on messages and photos, which leave plenty of room for assumptions.
The mistakes below come up again and again when existing paving is looked at after the event, and they have little to do with the skill of the people laying the blocks. None of them requires technical knowledge to avoid, only a little organisation before anyone starts digging.
Is agreeing the job verbally really a problem?
Yes, and it is mistake number one. A friendly conversation on the driveway, a handshake and a figure feel efficient, but they leave every detail open: depth of excavation, type of base, which sides get kerbs, who removes the rubble, and whether tax is included. When something goes wrong, there is nothing to refer back to. Ask for a written, itemised quote, even for a small job, and confirm changes by message. A written scope protects the contractor as much as the owner, and a reputable one will not object.
What other hiring mistakes are most common?
Comparing totals instead of contents
A lower total often means a smaller job. Without lining up items such as sub-base, bound layer, edging and waste removal, you cannot tell whether you are comparing two ways of doing the same work or two different works. Our post on what a block paving quote should list shows how to compare quotes properly.
Assuming the paperwork is someone else's job
Town hall procedures and community approvals are the owner's responsibility. Some owners assume the contractor will 'sort it out' and find later that nothing was submitted. Ask the town hall or a gestor which procedure applies, and if you are in a community of owners, ask the administrator first. Our guide to permits and rules for paving explains the basics.
Not fixing levels at doors, gates and garages
The finished level of new paving relative to door thresholds, garage floors and gates is decided at the start. Get it wrong and water runs inside, gates catch on the surface or a step appears where there was none. Agree these levels on site and write them down before the base is built.
Choosing colour from a single block
One sample in your hand, in strong sunlight, looks very different from a whole driveway. Blended ranges also vary from block to block. Ask to see a laid area or several samples together, and look at them at different times of day before deciding. Check them next to your façade, gate and planting too, because surroundings change how a tone reads.
Which technical details do owners often overlook?
Leaving drainage to chance
Surface water must go somewhere. If the quote does not mention falls or outlets, ask where the water will end up. A channel at the garage, a gully at the low corner or a planted strip are all fine; water flowing against the house is not.
Ignoring the edges
Owners rarely ask about kerbs and edging, yet they are what keep interlocking paving tight. If one side of the drive meets a lawn or a flower bed, ask how it will be restrained. Our page on kerbs and edging explains why this matters.
Forgetting what lies underneath
Water pipes, irrigation lines, pool pipework and cables often run under driveways and terraces. Telling the contractor where you think they are, even roughly, avoids damage during excavation and allows access points to be planned into the new surface. Old plans from the original build, if you have them, are worth sharing.
Are payment terms part of the problem?
They can be. Paying a large share in cash before any material reaches the site leaves you with little leverage if the job stalls, and no invoice means no record of what was agreed. A fair arrangement links payments to visible progress, for example material delivered, base completed and surface finished, and every payment is matched by an invoice showing the legal name, tax number and IVA.
It also helps to agree in writing what happens if hidden problems appear, such as buried rubble or a soft patch of ground under the old surface. A short clause saying that any extra work will be described, priced and approved by you before it is carried out removes most of the tension that otherwise builds around unexpected findings. Keep all of this in the same message thread as the quote, so the full history of the job sits in one place.
How does being abroad change the risks?
The ninth mistake is not agreeing how you will follow the job. Without a routine, owners hear nothing for a week and then receive a photo of a finished surface they would have changed if asked earlier. A simple plan prevents this.
- Agree which stages you want photos of: excavation, base, levels, first laid area, finish.
- Name one person on each side for decisions.
- Confirm decisions in writing, even short ones.
- Ask for a short video of falls before laying if you cannot visit.
- Arrange access with a neighbour or key holder in advance.
We work this way with owners who are not in Spain while the job is under way, and the photo updates are part of how we organise the work rather than an extra. The routine is agreed with each owner, so it can be lighter or more detailed depending on what you prefer.
How can I avoid all of these at once?
Most of the mistakes disappear with three habits: a written itemised scope, a short list of direct questions asked of every contractor, and an agreed update routine. If you want a ready-made list, our guide to choosing a paving contractor sets out the questions, and our installer checklist is a shorter version to keep at hand.

Frequently asked questions
What is the biggest mistake when hiring a paving contractor?
Agreeing the job verbally. Without a written, itemised quote, details such as excavation depth, base type, edging, waste removal and tax are left open, and there is nothing to refer to if expectations differ later.
Does the paving contractor handle the town hall paperwork?
Not as a rule. The owner is responsible for submitting the correct procedure, often with a gestor or architect. A contractor can provide an itemised quote and a description of the works to support the submission.
Why does the level at the front door matter so much?
If the new paving is too high relative to door thresholds or garage floors, rainwater can run inside. Too low, and a step appears. Agreeing finished levels at the start avoids costly corrections later.
How should I choose the colour of my pavers?
Look at several samples together, ideally a laid area, and view them at different times of day. A single block in bright sunlight rarely represents how a whole driveway will look, especially with blended ranges.
Should I tell the contractor where pipes and cables run?
Yes. Even rough information about water pipes, irrigation, pool pipework or cables helps avoid damage during excavation and allows access points or sleeves to be planned before the new surface is laid.
Do I need my community's approval to repave?
If the area is a common element, a resolution of the owners' meeting is required under the Horizontal Property Law. Even private areas may be subject to community statutes. Ask the community administrator before committing to any work.
How can I follow a paving job from abroad?
Agree in advance which stages you want photos or short videos of, name one contact for decisions, confirm choices in writing and arrange access through a key holder. That routine prevents surprises when you next visit.
Why ask about edging if the paving looks fine?
Edging is what keeps interlocking blocks tight. Where paving meets lawns or beds without a firm kerb, the outer rows tend to drift and the joints open over time. It is a detail that is easy to leave out of a quote.
Is a neighbour's recommendation enough to hire a contractor?
It is a good starting point, but still ask for a written itemised quote and the same questions you would ask anyone else. Every property has different ground, access and drainage, so a good result next door does not settle the details of yours.
What should I do if the quote does not mention drainage?
Ask where surface water will go and how the falls will be set. A good answer names a destination such as a channel, gully or planted strip. Have the answer added to the quote.
