Woodworm in London Homes – What you Need to Know

Woodworm in London Homes – What you Need to Know

3rd July, 2025

There are several varieties of beetle that likes to lay its eggs in timber, burrowing small holes that quickly cause structural damage to wood. The Common Furniture Beetle and the Death Watch Beetle are the two main culprits in the United Kingdom and once a house is infected, the larvae develop quickly and the problem expands to other areas of the property.

Things that are an indication of woodworm infestation

The following are sure signs that woodworm is present in your home:

  • Small round holes in timber with tiny mounds of dust next to each.
  • Crumbling edges of lengths of timber.
  • Beetles emerging from holes.
  • Dead beetles on the floor below window frames.
  • Creamy white eggs that protrude from the holes.

Check all timber, window and door frames, skirting and architrave, as well as roof joists and rafters and let’s not forget the staircase. Shine a torch under the stairs to see in all the corners.

What is the best way to treat woodworm?

At London Damp Surveys, we provide accurate assessments of a property that is infected with woodworm. We typically recommend the use of a water-based insecticide; once sprayed, the chemical quickly seeps into the wood, eliminating both beetles and larvae; even the woodworm that are deeply burrowed into the timber will eventually succumb when they approach the surface and the active ingredients of the solution remain long after the substance has dried, ensuring a total wipe-out.

What species of timber does woodworm infect?

These beetles are very hardy and they like both hardwood and softwood; a damp and humid environment is ideal for woodworm and an infestation can occur at any time of the year. It is important to understand the difference between woodworm and fungal growth, with the latter, there are no minute round holes. The condition of the timber has a bearing on whether beetles will nest or not and very dry wood is ideal.

Termite damage

Termites actually consume timber and it doesn’t take long before these destructive insects cause serious damage to wooden frames and structures. We have all the right recommendations for termite infestation and once the culprit has been identified, the right treatment can be recommended.

Be proactive with insect infestation

London property owners should be proactive when it comes to woodworm, termites and other destructive life forms that can invade a UK property. If you have lived in your London home for a few years and have never had the building inspected for damp, mould and woodworm, now is the ideal time to order a damp survey, which would reveal any woodworm or rot issues.

Let the professionals as London Damp Surveys assess your London home with a cost-effective building inspection; call us on 0207 305 5997 or fill out the online form on this website and arrange for a thorough survey. We issue a detailed report within 24 hours of the survey completion and our costs are very competitive.

£299 + VAT
Lab Analysis Of Plaster

Laboratory analysis Of plaster identifies hygroscopic salts such as chlorides and nitrates. which indicate whether damp is caused by rising groundwater or by plumbing leaks, This testing removes guesswork, allowing the exact source of moisture to be identified so the correct treatment is applied rather than carrying out unnecessary damp-proofing work.

£299 + VAT
Mould Lab Swab Testing, qPCR on DNA

qPCR DNA mould testing detects microscopic mould spores that are invisible during a normal inspection and van remain hidden behind walls, floors. or inside building rkaterials. It identifies the exact mould species present and the contamination level, allowing hidden mould problems to be confirrned and properly treated before they affect the property or occupants’ health.

Qualifications: All our surveyors are PCA and CSRT qualified for remedial treatments and also CSSW qualified for structural waterproofing.
Next day report: You will receive the report within 24 hours of the inspection taking place.

These are the tools we use

A damp meter

A 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.

Inspection Drone

Inspection Drone

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 Swab Test Kit

Mould Swab Test Kit

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.

Plaster Salt Analysis Lab

Plaster Salt Analysis Lab

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.
