Expertible

We’ve just launched our new Digital Downloads page on Expertible!

Our aim is to empower homeowners to make the right decisions for their homes, so we’ve created a number of free handy infographics and digital downloads on various topics related to older buildings.

Head over to the Damp section on our website, or see the comments for the link.

Keep your eye on that page as we’re always updating it with new helpful resources.

Most damp “surveys” are not just surveys.

They are part of a sales process.

When the person investigating your walls also sells the treatment, the outcome is rarely neutral. Diagnosis and product are bundled together. Intervention becomes the default.

Drill. Inject. Seal.

Different houses. Same prescription.

This is not about bad people. It is about incentives. When revenue depends on installation, installation quietly becomes the answer.

Older buildings are not standard assets. They are material systems. Solid walls, lime mortars, evaporation pathways, ground levels, ventilation. Moisture behaves differently in them.

Treating every tide mark with the same chemical solution is not building science, it is a standardised sales patter. Products to mask the issue, doesn’t mean it’s not still there.

There is another way.

Separate diagnosis from product. Start with someone who understands traditional buildings and has nothing to sell you. That can begin with a focused video consultation, helping you understand the cause, decide whether a site visit is even necessary, who should carry it out, and what it should reasonably cost.

That is how you move from a default “cure” to a tailored plan.

Before you approve invasive work, pause.

Your home deserves more than a sales pitch masquerading as a diagnosis.

For decades, we have treated damp in older buildings as a product problem; in reality, it is an incentive problem.

When diagnosis and installation sit inside the same business model, intervention becomes the default outcome. Drill, inject, tank, repeat. No matter the building, it’s the same prescription.

That structure is scalable, repeatable and profitable.

However, older buildings are not standardised assets. They are material systems with solid walls, lime mortars, evaporation pathways, varying ground levels, ventilation needs… moisture behaves differently in them.

When commercial incentives reward installation, it becomes the only answer; whether or not it addresses the root cause.

This is not about bad actors, but a system that bundles advice with product and badges it as diagnosis.

The result? An endemic cycle of invasive damp proofing, trapped moisture, blown render, spalling masonry, and more “treatment” sold to fix the consequences of the last one.

We believe there is a better structure.

Separate diagnosis from product.
Unbundle advice from sales.
Understand the building before prescribing the cure.

If we want our older building stock to thrive, we need to change not just the treatment, but the incentives behind it.

Given damp issues can be so common with old buildings we created this little infographic (using some online tools) on the process of elimination that damp experts run through.

To be clear, this is about identifying the CAUSE of a damp issue and not simply trying to treat the symptoms (which is what most ‘damp proofing’ strategies do).

When you’ve identified the actual cause then it can often be a simple or DIY thing to remedy with some guidance.

For those who’ve not heard of Expertible before, it’s a service that has been created having seen homeowners fall foul of various sales-driven ‘solutions’ attempting to repair their homes.

We got fed up of homeowners always being sold something, or getting ‘free’ advice that wasn’t free because it was just to sell a service or product. With Expertible you book a 1-1 video call with a heritage building expert and you’re only paying for that expert’s time, experience and expertise; not them trying to get a sale out of you. Finally, someone with YOUR best interests first.

Not everyone will need help from an expert to diagnose their damp, which is why we regularly post how to investigate things for yourself on here. But for those who would like some help, we have many building pathology experts with slots available to book who can support you if you get stuck.

You may have seen the government’s new Warm Homes Plan published this week.
It’s a big and largely positive commitment to upgrading homes, but reading it prompted a few reflections about what really matters once the work is done.

Beyond the headlines, success shows up in how homes actually feel over time, warmth, comfort, and health.

We’ve shared some calm, homeowner-focused thoughts in the slides.

What would “success” look like in your home?

Many problems in older buildings aren’t caused by age, they’re caused by misunderstanding.

We’ve started creating a series of longer form based videos to help explain how actually work, beginning with moisture, , and .

This first video looks at what condensation really is, how moisture behaves in air, and why cold outside air in winter is often drier than the air inside our homes.

These ideas are frequently misunderstood, which can lead to poor decisions and unnecessary interventions.

The aim is not to offer quick fixes, but to make the underlying easier to understand, so people can make more confident, proportionate choices about their buildings.

If you live in or care for an older property and have ever felt unsure about conflicting advice around damp or condensation, this may be useful.

Most people assume that opening windows in winter makes damp problems worse. Cold air feels wet, it is often raining, and the room cools down immediately, bu...

Those little holes in your beams? Everyone calls it “woodworm” and reaches for the chemical spray.

Here’s the problem:
Chemical treatments rarely reach the beetle larvae buried deep in the timber. They just scatter toxins around your home, kill the harmless species that actually help control pests, and do nothing for the real cause.

And the real cause? Damp.
Beetles thrive in high-moisture timber. Dry it out and they can’t survive.
That means:
• Fixing leaks.
• Removing modern paints, sealants or renders that trap moisture.
• Improving ventilation so damp can actually evaporate.

Once the timber moisture content drops below around 12%, your beams become a very unfriendly place for beetles. No chemicals. No gimmicks. Just building science.

If you’re not sure where to start, that’s exactly why we built Expertible; a place to speak directly to a surveyor who specialises in old buildings. They’ll tell you what’s causing the problem and how to fix it… without selling you products you don’t need.

If your house is older than your gran, this is for you.

Historic England just confirmed what we’ve all been suspecting; internal wall insulation can make things WORSE if done wrong.

Every single case they studied showed increased moisture risk, even with thin layers.

IT’s because if moisture gets trapped, or is slowed down evaporating, you’re not just risking damp and mould, you’re also making your walls colder.

That means higher heating bills too.

A wet wall is a crap insulator.

Want to do the right thing for your home without falling for salesy “solutions”? That’s exactly why we created Expertible. Impartial advice from people who know how these buildings work.
