Protect floors, joists and structural timber

Do not ignore signs of timber damage

Woodworm is a general term for wood-boring insect larvae that can leave small holes and fine dust in timber. Similar damage can be old or inactive, which is why an inspection is important before treatment is considered.

Timber can also soften or decay because of wet rot, dry rot or persistent damp conditions. We assess visible timbers, nearby moisture sources and accessible structural areas, then explain the evidence and suitable next steps without overstating the problem.

Early warning signs

Small symptoms can point to a wider moisture problem.

Photographs help us understand the issue, but an on-site inspection is the best way to assess the likely cause.

Common signs that should be investigated

One sign does not always confirm the cause. A survey helps establish what is happening and whether treatment is actually needed.

What those timber signs could mean

Not every flight hole means there is an active infestation, and timber decay often has a moisture source that must be addressed. A careful inspection helps establish the condition, likely activity and any contributing damp or ventilation issue.

The important difference

The right response depends on whether the damage is active, historic or being driven by an unresolved moisture problem.

Active woodworm

Fresh frass, clean-edged flight holes and seasonal insect activity may indicate a current infestation.

Historic damage

Old flight holes can remain visible long after activity has stopped and may not require treatment.

Wet rot or dry rot

Persistent moisture and poor ventilation can cause fungal decay that needs the moisture source addressed.

A joined-up assessment

How we narrow down the cause

We assess the evidence together rather than relying on one reading or one visible patch.

      Trustindex verifies that the original source of the review is Google. Very professional, very clean and tidy and the workmanship was also very very good. My husband is a builder so his standards are very very high, YDS exceeded his expectations which is very surprising as he’s a tough old fella to please lol. Kat was wonderful in the office and Dave was very very good with his knowledge and thermal imaging software to identify exactly where th damp was without any question about it. We had 2 other quotes who said there was loads of extra damp which Dave shown me on his thermal imaging software that it was bone dry. Very honest company. Thanks guys

Turned up at the exact time and date the job was planned in for, completed it within the time frame agreed, they were super clean and tidy. They were super fussy with the attention to detail so the finish was impeccable. Dave was amazing and Kat in the office was very attentive and got back to me with any questions I had within mins. Fantastic experience all round.

    Trustindex verifies that the original source of the review is Google. I’m blown away by this company, genuinely. I’d had 3 quotes from local companies and YDS had a price guarantee which basically beat any quote that was like for like, they literally covered all basis, PCA accreditation (don’t use a company unless they have this) insurance backed guarantee for 30 years and 100% money back guarantee. They turned up on time, super clean, had emails all the time updating the process and invoicing, plus text messages. Super clarity on everything. Dave was a great guy and felt super confident with his level of expertise. Good genuine local company.

    Trustindex verifies that the original source of the review is Google. Very happy with this company, I had a couple of local conpanies quote, they were not specialists and didn’t have any accreditations to say they were. Your Damp Specialists had every accreditation relevant to the damp industry. They also had a price guarantee so they beat another companies quote that was like for like. Overall I have zero complaints and can honestly say that they are worth every penny.

    Trustindex verifies that the original source of the review is Google. Amazing company, from the very first point of contact I can’t fault them in any way whatsoever. They were very very knowledgeable. The house was very old and the damp had failed from three different companies that had tried to cure it in the past 4 years. The amount of money I’ve spent has been crazy. Once I’d done my research on accreditations, there’s literally only 2 companies in the whole of Teesside who have the correct accreditations who are legitimate damp specialists, with your damp specialists being one of them. It’s been 18 months now and not even a hint of damp. Five stars all the way. Do your homework on systems and accreditations before taking any steps forward.

    Trustindex verifies that the original source of the review is Google. Great service, arrived on time to complete the job. Advised properly on the cause of our mould, since installation we have had no return of mould. Not even in the small bathroom where it has been returning every few weeks. Price was also a lot more competitive than other quotes I had!
