Why You Should Be Wary of “Free” Damp and Timber Reports: A Real Story from a Recent Case

Every week, I come across homeowners who’ve been left scratching their heads after receiving a so-called free damp or timber report. On the surface, these offers sound appealing; who doesn’t like something free? But as the saying goes, if it sounds too good to be true, it probably is.

Recently, I was contacted by a couple who had received one of these “free reports” from a damp contractor. They wanted me to take a look and see if I could “beat the quote.” What unfolded next is a perfect example of why it pays to be cautious about free surveys and why professional, independent damp and timber inspections are worth every penny.

The “Free” Report That Raised Questions

The couple had been informed by a contractor that their property was suffering from rising damp and required a new chemical damp proof course (DPC). The quote was, unsurprisingly, expensive, and they wanted to know whether I could do the same job for a lower price.

They kindly sent over a copy of the report they’d been given. Right away, I could see why they were confused. The document was filled with technical jargon, generic statements, and vague conclusions. It lacked proper photographic evidence, clear moisture readings, or any explanation of how the so-called “rising damp” diagnosis had been reached.

Even more concerning, there was no mention of other possible causes of damp, something every good surveyor should always investigate before jumping to conclusions.

What I Found After Looking Closer

Before even visiting the property, I took the time to carefully go through the report and study the photos the couple had sent me. I also did a quick check of the property on Google Maps Street View. From what I could see, the signs didn’t point to rising damp at all.

Instead, the issues looked like typical maintenance problems, things like uncapped chimney pots, high external ground levels, and possibly penetrating damp from rainwater goods. All of these can cause moisture to appear on walls, which is often mistaken for rising damp.

In other words, the moisture potential wasn’t down to “rising damp”. All the issues I could see can usually be fixed with some basic remedial work, not an expensive new damp proof course.

A Proper Conversation Makes All the Difference

I called the couple to discuss what I’d seen. We ended up having a long, honest conversation about the property, the supposed findings, and the kind of work they’d been quoted for.

During the call, I explained how rising damp is actually quite rare, and how it’s often misdiagnosed by contractors whose business depends on selling chemical DPC injections. I also talked them through the other possible causes of the damp patches shown in their photos and explained how these could be resolved far more simply and cost-effectively.

By the end of our chat, they felt much clearer about what was really going on and said they wanted me to carry out a proper, damp and timber survey instead. They said they trusted what I’d explained, and that conversation alone saved them from potentially wasting thousands of pounds on unnecessary work.

The Problem with “Free” Damp and Timber Reports

This isn’t an isolated case. The damp-proofing industry has a long-standing issue with so-called free surveys.

Here’s the truth: these reports are rarely free. The cost is simply hidden in the inflated quotation for the “repairs” that follow. The purpose of the free survey isn’t to give you an accurate diagnosis, it’s to create a sales opportunity.

Many of these companies operate with one goal in mind: to sell you a chemical damp proof course. Regardless of the actual cause of moisture in your property, the conclusion is almost always the same: “You have rising damp, and you need a new DPC.”

The problem is that in many cases, there’s no evidence of rising damp at all. Instead, the dampness is caused by things like:

Bridged cavities
Leaking gutters or downpipes
Defective pointing or rendering
High external ground levels
Poor internal ventilation
Condensation and lifestyle factors

None of these issues can be fixed by injecting a damp proof course. But a sales-driven survey won’t tell you that.

What Happened Next

Once the couple booked their full survey, I was able to inspect the property properly. As expected, there was no rising damp. Instead, the dampness was caused by a combination of bridged damp proof course (thanks to high external paving), chimney salts (pots aren’t capped), and a few areas of defective rainwater goods.

The solution? Lowering the ground level slightly, unblocking some air bricks, capping the chimney, and replacing the guttering. No chemicals, no injections, and certainly no unnecessary drilling into the walls.

They were relieved — not only because it saved them a large sum of money, but also because they finally understood what was really going on with their home.

The Lesson: Don’t Be Tempted by “Free”

If you take one thing away from this story, let it be this: don’t be tempted by companies offering free surveys or free reports.

While they might seem convenient at first, they can easily lead you down an expensive path. Moisture problems in buildings are often complex, and proper diagnosis requires time, skill, and independence. A free survey simply doesn’t allow for that; it’s a sales pitch dressed up as a professional service.

If a company’s business model relies on giving away reports for free, they’ll need to make their money somewhere else, and that usually means selling you something you don’t need.

A Better Way to Handle Damp Issues

If you suspect dampness, timber decay, or condensation problems in your property, the best thing you can do is to hire a damp and timber surveyor from a reputable company and talk to the surveyor. You’ll get an unbiased assessment, clear explanations, and practical advice tailored to your property.

You’ll also have peace of mind knowing that the recommendations are based on evidence, not on a sales target.

So, before agreeing to any expensive damp proofing work, take a step back and ask yourself: Has anyone actually proved it’s rising damp? If the only evidence you have comes from a free report, it’s worth getting a second opinion.

Final Thoughts

This case is just one of many examples showing how homeowners can be misled by free damp and timber reports. The couple I helped were lucky; they reached out for a second opinion before signing any contracts.

Sadly, many others aren’t so fortunate. They go ahead with unnecessary chemical DPC installations, only to find the damp returns months later because the real issue was never addressed.

So, my advice is simple: trust independent expertise, not free sales pitches.
A proper damp and timber survey might not be free, but it’s an investment that can save you thousands and ensure your home stays dry for years to come.
