Damp & Timber Surveyor — your shift
Look outside before you look at the wall — and the meter does not measure what people think it does. Read what this person needs, then tap the place that sorts it out.

What does a damp & timber surveyor do?
You work out why a wall is wet, which is almost never the reason the last person said, and you are paid by people who sell the cure.
Also called: damp surveyor, building pathology surveyor, timber decay specialist.
A day looks like
- 1You look outside first — gutters, ground levels, pointing — because most damp comes from something you can see from the garden.
- 2You measure with a meter that does not actually measure damp in masonry, and you know that.
- 3You tell somebody their house does not need a damp-proof course injection.
- 4You find rot in a joist end nobody had looked at, which matters far more than the stain on the wall.
Hardest part
Most of this industry is paid commission on treatments. The honest answer is usually 'clear your gutters and lower that flower bed', and it earns nobody anything.
Best part
Saving somebody four thousand pounds by pointing at a downpipe.
How you actually become a damp & timber surveyor
- At schoolA building or surveying background; damp and timber is a specialism on top.
- TrainingCSRT (remedial treatment) and building pathology qualifications.
- How longA couple of years of building experience, then specialist certification.
- Your first jobSurveyor's assistant or technician with a remedial contractor.
Frequently asked questions
- Is rising damp real?
- It exists but is far rarer than the industry's treatment volumes suggest. Most damp diagnosed as rising turns out to be condensation, bridged ground levels, or water getting in from above.
- Why is a moisture meter unreliable on walls?
- Electrical meters measure conductivity, and salts in masonry conduct even when the wall is dry. That is why a proper diagnosis uses a carbide test or drilled samples rather than a surface reading.
- Why does who pays the surveyor matter?
- Because much of the sector earns commission on treatments. An independent surveyor who does not sell the cure is the only one whose 'no treatment needed' is worth anything.
More from Architecture & Construction
Plumber
You find the leak, which is almost never where the damp is, and you work out what to turn off before you touch anything.
Site Manager
You run a site where eight different trades all need the same space on the same day, and you are the person who can stop any of them.
Groundworker
You dig the holes and lay the drains everything else depends on, and the two things that can kill you are collapse and what is already buried.
Building Control Inspector
You inspect work at the stages where it can still be seen, and you are the person who fails a pour nobody wants failed.
Structural Engineer
You calculate whether a building will stand up, and you put your name on the answer.
Demolition Supervisor
You take a building down in the reverse order it went up, and the two things that decide whether anybody gets hurt are sequence and asbestos.
Fire Safety Engineer
You design how everybody gets out of a building that is on fire, and how long the building has to hold up while they do.
Retrofit Insulation Installer
You make old houses warm, and the whole skill is doing it without trapping moisture inside the wall.
Architect
You decide what a building is — how it is entered, lit, used and lived in — inside a budget, a site and a set of regulations that all say no.
Quantity Surveyor
You work out what a building will cost before it exists, and then you defend or challenge every change to that number.
Crane Operator
You move several tonnes through the air over people's heads, mostly without being able to see where it is going.
Heat Pump Engineer
You replace a boiler with something that runs at half the temperature, which means you have to redesign how every room in the house gets warm.
Glazier
You fit glass, which is heavy, sharp and unforgiving — and you decide which kind of glass the law requires in each location.
Electrician
You install and test circuits that will be hidden inside walls, and the only thing that ever stands between a fault and a fire is that you tested it properly.
Carpenter
You set out, mark and cut timber to fit a building that is never quite square, and you only get to cut each piece once.
Bricklayer
You build walls to a line, level and plumb, at a speed that decides whether the job makes money — and the line is not a suggestion.
Scaffolder
You build the structure everybody else works from, and you build it while standing on the part you have already built.
Roofer
You keep water out of a building using overlapping pieces and gravity, working on a slope, above everything else.
Plasterer
You put a wet material on a wall and have a fixed number of minutes to make it flat, because it is setting while you work.
Steel Erector
You bolt a building's skeleton together in the air, and the frame is not stable until you have finished making it stable.
Land Surveyor
You establish where everything goes, to millimetres, and every other trade on the site builds off your marks without checking them.
