Woodworm & Timber Rot

Woodworm

The term ‘woodworm’ refers to two beetle species that are found in the UK; namely the Common Furniture Beetle and the Death Watch Beetle, both of these insect species bore holes in wood and lay their eggs. When the larvae hatches, they consume wood pulp until they become adults and the cycle is repeated; if not addressed, woodworm will cause serious damage to a London property and the problem will eventually spread throughout the building.

Signs of Woodworm Infestation

The tell-tale signs of woodworm include the following:

  • Tiny holes in wood – The beetle burrows small holes in the wood in order to deposit eggs; another sign is small mounds of wood dust next to the holes. If you notice this, it is time to call in the professionals who have the know-how and the equipment to eradicate woodworm from your home.
  • Adult beetles – A dark grey in colour, adult beetles might be seen around timber, which is a sure sign that woodworm are, in fact, present in your home.
  • Small white eggs – These might be clustered around small holes around window and door frames or on the floor below timber sections.
  • Crumbling edges – Woodworm typically affects the edges of timber lengths, which become cracked and brittle.
  • Small pieces of wood on the floor – Shards of timber can break off and drop to the floor.

If you notice any of the above signs, it is time to call London Damp Specialists on 020 8945 5547  or fill in the form on this website and we can arrange for one of our fully qualified damp surveyors can inspect your London home.

How London Damp Specialists Source Woodworm

We have more than 40 years of hands-on experience identifying woodworm, and we use state-of-the-art equipment to accurately assess whether woodworm is present in your London home.

Woodworm can be very destructive, which is why you need a definitive survey to determine if woodworm exists in your London property.

Wet & Dry Rot

These are destructive fungi that can impact the wood in your London home and wet rot demands a different treatment than dry rot. If you suspect that there is wet or dry rot in your home, don’t delay, call in London Damp Specialists for a definitive inspection from the foundations to the roof and everything in between. If we do find timber rot, we can recommend an established contractor to carry out remedial work.

Tell-Tale Signs of Wet & Dry Rot

Signs of wet & dry rot include the following:

  • Strange odour – A musty smell in the house
  • A soft and spongy feel to the wood
  • Cracking wood
  • Different appearance – Affected timber is often darker.
  • Fungal growth – Creamy or brown in colour, which is sometimes accompanied by a fluffy growth.
  • Brittle and dry wood – Dry rot causes the wood to become brittle and cracked edges are also apparent.

Damp conditions are ideal for wet and dry rot and if not dealt with, this can cause serious damage to a building.

If you are planning to invest in a London property, you should book our pre-purchase damp survey and one of our PCA-certified damp surveyors can inspect the property, looking for any signs of damp, mould and timber rot. Such a big investment demands that you do your due diligence and ensure that the building is in good condition and free from any moisture issues.

If you are already a homeowner in London and you can’t recall the last time you inspected the building for damp and timber rot, now is the perfect time to contact London Damp Specialists and book a professional damp survey from an accredited surveyor.
Many London homeowners ensure their property is free from damp issues by having the building inspected every 6 months and should there be any issues, the remedial work is minimal.

If you are at all concerned that your home might be under attack by wet or dry rot, don’t delay, call us on 020 8945 5547 and arrange for one of our PCA-certified damp surveyors to carry out a thorough inspection and you will receive a detailed report in your inbox the following day.

FAQs
What can I do to protect timber against woodworm?

There are specific chemicals that seep into timber, eventually eliminating all larvae; our surveyors are happy to discuss woodworm prevention at any time. While we do not offer damp-proofing services, we work with London’s leading Damp-proofing company that issues a no-quibble 30-year guarantee on all damp-proofing.

Do you include a quote for remedial work in the survey?

Yes, if remedial work is required, we are happy to give you a ballpark figure, what’s more, we can put you in touch with the best damp-proofing company in London. They would inspect the site and provide an on-the-spot quote and they issue a 30-year guarantee with all damp-proofing treatment. If you would like to book an independent damp survey, call us or simply leave a message on the website and we will arrange to inspect your home for signs of damp, mould and timber rot.

How often should I have my roof inspected?

Of course, the roof is the most important component of every building; it must endure the harsh climate and without regular inspections, serious damage can occur, especially the internal timber roof structure. Our independent survey includes a detailed roof inspection, which is done using a drone. This should be an annual thing and take note of what you can see of the roof; if there are overhanging trees, the guttering can be easily blocked and this is a major cause of penetrating damp.

How long has the company been in business?

London Damp Specialists was founded in 1981; the family-run business has been serving the London community with accurate damp surveys and providing quotes for damp-proofing work. We are an established organisation with the resources and know-how to inspect London homes, looking for signs of damp, mould and timber rot. Read a few of the testimonials and you can rest assured of the very best in terms of service, as we have an excellent reputation within the industry.

What are the causes of wet and dry rot?

Both of these fungi need a humid atmosphere to grow, which might be due to rising damp or condensation; the surveyor carries out a ventilation flow test to accurately measure air movement. If condensation forms, this is a breeding ground for fungal growth and the timber is quickly compromised.

These are the tools we use

Damp Meter

Damp Meter

A damp meter is a diagnostic tool used to detect and measure moisture levels within building materials such as plaster, brick, timber, and concrete.

Borescope camera

Borescope camera

borescope camera is a small inspection camera attached to a flexible semi-rigid cable that allows you to see inside areas that are otherwise inaccessible.

Drone Inspection

Drone Inspection

A drone is a remotely operated aerial device equipped with a camera that allows visual inspection from above without the need for scaffolding or ladder.

Air Humidity Sensor

Air Humidity Sensor

Air humidity sensor measures the amount of moisture present in the air, expressed as relative humidity (RH) in percentage. It helps determine whether indoor conditions are contributing to condensation, mould growth, or damp-related issues.

Thermal Imaging Camera

Thermal Imaging Camera

A thermal imaging camera detects temperature differences on surfaces by using infrared technology to produce a heat map image. In damp investigations, it helps identify cold spots, moisture intrusion, insulation defects, thermal bridging and leaks.

Air Flow Ventilation Detector

Air Flow Ventilation Detector

An air flow ventilation detector measures the movement and volume of air passing through vents, extractor fans, and air bricks. It confirms whether ventilation systems are working properly and achieving adequate air changes within a room. Poor airflow leads to trapped moisture, high humidity, condensation on cold surfaces, and ultimately mould growth.

Mould Lab Swab Testing

Mould Lab Swab Testing

A mould swab test is carried out to confirm the presence of hidden mould growth and identify the specific species involved. Surface mould is not always visible, especially behind furniture, inside cavities, or within ventilation systems. Laboratory analysis of a swab sample determines whether active mould spores are present and what type they are, which helps assess potential health risks and decide the correct remediation approach rather than relying on visual assumption alone.

Lab Analysis of Plaster

Lab Analysis of Plaster

Laboratory analysis of plaster is used to identify the type of salts present within the material, typically chlorides and nitrates. The presence and concentration of these salts help determine whether the moisture source is consistent with rising damp, ground contamination, or another forms [sic] of water ingress. such as mains water leak, This removes guesswork and prevents misdiagnosis, ensuring the correct remedial treatment is specified rather than applying unnecessary or ineffective solutions.
