According to the damp-proofing industry, as you are reading this, woodworm is reducing your rafters and floorboards to dust. It's really only a matter of time until the roof comes in or you fall through the floor.

The only "solution" is to soak your home in expensive chemicals - at significant cost to your wallet, and the quality of the air you breathe.

The truth is far less dramatic, and much less costly.

Most homes I survey show historic sings of woodwork. Historic. Not current. Not even recent. Woodworm is often already present in timber when it's used to build the house. When the wood dries, the woodworm fly away, because woodworm need moisture to soften the wood that they rely on to survive.

The answer, then, is not chemicals; the answer is to manage the environment to keep timber below the threshold at which woodworm can eat and breed. To do so, you need to measure the moisture content of the wood, as well as temperature and relative humidity (which is where I come in).

If you'd like help with a damp or timber issue, please feel free to message or call.

Investigation with verbal/written advice: £160.
Full survey: £225.

* Please be aware that I charge a £50 supplement if longer travelling is involved (45 minutes or above).

Surveying an old house in Helensburgh last weekend brought home that most damp proofing is unnecessary, and often damaging.

The previous owner of the client’s property had encased breathable sandstone, and lime plaster, in waterproof paint and wallpaper. Moisture was trapped inside the property and was causing damage.

The solution was to strip the wallpaper and to begin an inexpensive process of drying and ventilating. The solution was not more damp proofing, it rarely is.

When it comes to damp in older homes, you’d be surprised how often it can be remedied for effectively nothing.

I have nothing to sell except expertise in helping you resolve damp issues as cheaply as possible, without building work.

My prices are as follows:

Damp investigation and verbal/written advice: £160.

Full survey and written report: £225

On average, my damp investigations save homeowners around £4,000 in unnecessary remedial work. Most damp problems aren’t structural — they’re building‑physics issues that can be fixed cheaply once properly diagnosed.

If you have a damp issue and would prefer not to have to worry about being sold unnecessary and expensive damp treatments, please message or call me.

£160 for investigation and advice only.
£225 for a full survey report.

Three Reasons You Should Seal Your Loft Hatch

1. Stop losing heat

Warm air rises. If your loft hatch has gaps, you’re heating the attic. With energy prices where they are, every gap matters. Heat the parts of the house you live in.

2. Prevent attic condensation

In autumn and winter, attics get cold. Moist indoor air rises, slips through gaps, and condenses on cold timbers. That leads to mould and long‑term timber damage.

3. Reduce draughts and cold spots

Your home is pressurised. If the top leaks air, the bottom pulls it in through skirtings, window frames, and floor gaps. These areas get colder and become zones for damp and mould. (This can lead to “rising damp” misdiagnoses.)

A simple £20 seal around the loft hatch keeps the heat you pay for inside the house and helps prevent multiple damp issues.

Small fix, big impact.

On Friday, a customer in Greenock wanted me to confirm that the render external to his bedroom needed replaced as it was causing damp internally; this is what he had been told by a builder.

The problem was much simpler, and much cheaper to solve.

There was a very high internal moisture load caused by the three occupants and a lack of ventilation (no extractor in the bathroom, cooker hood not functioning, no trickle vents on windows).

The customer was trying to alleviate the damp in his bedroom by using a very small dehumidifier. Given that three people in a property can generate as much as 14 litres of moisture a day, this is like attempting to empty a bath with a thimble.

The dehumidifier was making matters worse by convecting air around the bedroom more effectively than it should have been, where it was landing on cold surfaces, condensing and causing mould.

The customer had painted the wall with waterproof paint as he had been told the damp was coming from outside. This meant that vapour was collecting in the room as it couldn’t diffuse outwards through the wall.

The solution was simply to maintain a steady temperature in the bedroom, open the windows regularly to flush moisture, and buy a larger capacity condenser dehumidifier to cope with the large amount of moisture.

As is often the case, what was required was building physics and not expensive building works.

If you’re seeing damp patches or mould, an independent investigation can save you a lot of money.

Damp surveying isn’t rocket science, but it is a science.

If your surveyor isn’t measuring humidity, dew point, vapour pressure, ventilation rates, and using thermal imaging, then it’s a sales call and not a survey.

If you prefer building physics to building works and would rather avoid expensive and (almost certainly) unnecessary damp-proofing, I’d be happy to help you with your damp issues.

Investigation and verbal/written advice only: £160.

Full written survey with evidence and photographs: £225.

A lady in Helensburgh asked me to inspect the wood in her attic. She had bought a new home and the Home Report stated that there may be woodworm.

I inspected the attic and found no sign of woodworm - the wood was in good condition, nice and dry, and woodworm could not survive in the attic’s dry atmosphere.

If your attic has no leaks and the humidity is reasonable then you have nothing to fear. Even if woodworm larvae are already inside the timber when it is installed in your home (and this is common), they cannot survive in dry conditions and will die off or fly away of their own accord.

The customer asked me to inspect as she knew that I would not try to sell her a chemical solution to a non-existent problem. She wanted peace of mind from someone with nothing to sell except answers.

If you’d like clarity for a damp or timber issue, please call or message me.

My prices are clear and won’t change on the day:

Investigation and verbal/written advice: £160.

Full damp report for estate agents/insurance, etc: £225.

Selling your home is fraught with pitfalls.

Two weeks ago, a customer asked me to conduct a full damp survey to determine the accuracy of a damp and timber survey carried out by a damp-proofing company.

This company was asked to do this pre-purchase survey by a potential buyer, because the home report was scored a 2 for damp by the RICS property surveyor, based on high moisture meter readings in a wall.

It is important to point out that moisture meters do not, in fact, measure moisture: they measure electrical conductivity and will give high readings for, amongst other things…

metal in the wall
hygroscopic salts
carbon or soot
surface condensation
fresh plaster or paint
electrical cables
high humidity
voids and cavities

RICS home surveyors do not investigate the meter readings - they simply record them and recommend further investigation by a Property Care Association-aligned surveyor (often a salesman for a damp-proofing company). By doing so, they pass liability on.

The PCA-aligned surveyor who attended my client’s property performed a brief and cursory visual inspection. The result of this visit was a diagnosis of rising damp and rotting floorboards.

The cost to fix these issues? £8500.

I conducted a full survey of the property and found no evidence of damp or timber damage. (See attached endoscope pictures of the floorboards and thermal imaging of the suspect wall - all in good order.)

The homeowner received a building physics-based full report which the estate agent uses to show other potential buyers, thereby offsetting the 2 rating in the home report.

If you would like to me survey your property before the home report is performed, I’ll provide a report for the RICS surveyor to help ward off a 2 rating for damp and all the aggravation that entails.

The cost: £225.

This week I investigated a damp problem that had been developing slowly but steadily. Indoors, an area of plaster was blowing in small patches and the wall surface was noticeably cooler than adjacent areas, which is a sign that moisture is moving through the structure where it shouldn’t be.

Outside, the source was clear: a blocked gutter that had been overflowing, soaking the same section of masonry every time it rained. A wall that gets wet is one thing; a wall that is repeatedly soaked is another. One will dry out. The other will gradually drive moisture deeper into the structure, eventually showing up indoors. The real danger isn’t the water itself — it’s the loss of drying time. In our climate, long wet spells and short drying windows mean that an overflowing gutter or a leaking downpipe can keep a wall wet for weeks. When the wall never resets to a dry baseline, moisture begins to migrate inward.

Once moisture moves past the outer few millimetres, the internal vapour pressure rises. That’s when you start getting interstitial condensation — moisture forming within the wall’s thickness rather than on the surface — which cools the inner face further and encourages more vapour to condense. Over time, this cycle can lead to blown plaster, salt deposition, mould, and fungal decay at the skirting line where timber stays in contact with a persistently damp zone.

Clearing the gutter breaks the cycle. The wall can dry, the vapour pressure will fall, and the internal symptoms will stabilise and can be dealt with cheaply.

Many damp problems begin outside, and most can be prevented with simple maintenance before moisture has time to travel.

Clear your gutters - a stitch in time saves nine.
