Renovation disagreements rarely begin with someone planning to cause a problem.
They usually begin with a conversation.
You explain what you want. The contractor nods. Everyone appears to understand. Work begins, decisions are made quickly and several weeks later, two people remember the same conversation very differently.
I learned that lesson through experience.
Now, before renovation work begins, I photograph everything—not because I expect an argument, but because memory is not evidence.
If you are still deciding whether to buy a renovation project in Spain, my questions to ask before you buy cover the checks that come before the work begins.
BEFORE THE WORK STARTS
Excitement makes it tempting to begin immediately.
You have finally found someone who can do the work. You have discussed the price, imagined the finished space and perhaps already bought some of the materials.
But before anyone removes a door, lifts a tile or touches a wall, take photographs and video of the entire property.
Record:
- Every wall, floor and ceiling
- Doors, windows and locks
- Sockets, switches and light fittings
- Plumbing fixtures and appliances
- Furniture or items remaining in the property
- Existing cracks, stains and damage
- Materials already delivered to the site
Walk through each room slowly. Open cupboards. Film corners. Include the date where possible and keep the original files.
Five careful minutes can prevent an expensive disagreement later.
WRITE DOWN WHAT IS INCLUDED
A quotation may look detailed while still leaving important questions unanswered.
“Renovate bathroom” sounds clear until you need to know whether it includes removing the old fittings, disposing of the waste, waterproofing, plumbing changes, tiles, grout, paint and installation of the new fixtures.
Do not assume that something obvious to you is also included in the contractor’s price.
The written scope should identify:
- What will be removed
- What will be repaired or replaced
- Who supplies each material
- The quality or model of important items
- What is specifically excluded
- How additional work will be approved
- When payments become due
This does not require a complicated legal document. It requires clarity.
A short written description is much safer than a long conversation nobody can prove later.
DOCUMENT EVERY CHANGE
Renovations rarely follow the original plan perfectly.
A wall is opened and reveals a problem. A product becomes unavailable. The owner changes their mind. The contractor recommends a different solution.
Changes are normal. Undocumented changes are dangerous.
When something changes, confirm it in writing before the work continues:
“This is what we agreed to change. This is the additional cost. This is how it affects the completion date.”
A message or email may feel unnecessarily formal when everyone is getting along. It becomes extremely valuable when the final invoice arrives.
DO NOT LET PAYMENTS GET AHEAD OF THE WORK
A deposit may be reasonable, especially when materials must be ordered. But paying too much too early removes one of the few protections you have.
Where possible, connect payments to visible stages of progress.
For example:
- Deposit after agreeing the written scope
- Payment after materials arrive
- Payment after a defined stage is completed
- Final balance after inspection and correction of outstanding items
The exact structure will depend on the project and local practice, but the principle remains the same: the money paid should broadly reflect the work completed.
INSPECT BEFORE THE FINAL PAYMENT
Finishing a renovation does not mean that everything is finished properly.
Test doors, windows, taps, drains, sockets, lights and appliances. Look closely at joins, edges, sealant, paintwork and damaged surfaces.
Write a snagging list and photograph each item.
Do this before paying the final balance—not several weeks later when people have moved on to other projects.
A professional contractor should expect reasonable checks. Inspection is not an accusation. It is part of completing the work.
THE LESSON
The most valuable renovation habit I have learned is simple:
Document the property before work begins, document the agreement and document every change.
Photographs cannot guarantee that a renovation will go smoothly. A written scope cannot prevent every unexpected expense. But together, they replace uncertain memories with something everyone can check.
I used to think detailed documentation suggested that I did not trust people—and believe me, some of them actually said that out loud.
Now I see it differently.
Clear records protect both sides. They reduce misunderstandings, make decisions easier and help honest contractors demonstrate what they have completed.
Memory changes.
Evidence does not.
