The Project

This gorgeous church had seen better days and was in need of a bit of TLC. A survey we conducted revealed signs of woodworm in the structural timbers as well as condensation and penetrating damp all over the building. Given the structure’s age, we took care when treating the timbers for woodworm infestations. We tackled the condensation that formed due to the rising and penetrating damp and treated it by repairing exterior renderings. Then, we removed the interior plastering so we could apply fresh waterproof plaster, to prevent future damage.

How We Approached the Project

With a structure as old as St. James’s Church, it was not altogether surprising that these issues developed, but we knew right away that it was in need of immediate repair before the damage to the structure spread and parts of the building deteriorated beyond repair.

Constantly mindful of the age and heritage of the church, our LDS (London Damp Specialists) team began by carefully treating all timbers for signs of woodworm infestation.

What Is Woodworm?

“Timber Treatment” is a term that commonly refers to the degradation of wood in buildings, particularly those built many years ago when there was often an abundance of lumber incorporated—up to 75%. Consequently, it’s important to take steps towards protecting your property from any serious timber decayers and destroyers. The three key culprits are dry rot, wet rot, and woodworm, all capable of causing varying levels of damage. Our damp professionals are seasoned experts when it comes to timber treatments, especially on older, more delicate structures.

Woodworm, in particular, is a nasty problem to have. Wood-boring insects, whose larvae burrow into timber and feed on it for a lengthy period of time, are collectively referred to as “woodworms.” The eggs laid by these species on the surface of wood quickly hatch upon contact with air and begin their journey through the timber.

Wood-boring insects can cause serious damage to wooden structures, and if a woodworm treatment is not completed fully, the problem will simply reoccur. To prevent this cyclical process from continuing, it’s important that you seek out experienced professionals who have the ability to provide an effective and complete woodworm treatment. Eliminating these pests for good should be your first priority when protecting your property.

Tackling the Condensation

The other major issue present in the building was the condensation that had formed as a result of the penetrating and rising damp, so we carried out repairs to the failed exterior render. The interior plaster was removed and treated with waterproof plaster, preventing future water damage and allowing the church to remain a stunning community focal point.

Why Does Penetrating and Rising Damp Occur?

If you’re noticing moisture spots on your ceiling, the culprits may be cracked tiles in the roof or even issues with plumbing pipes. In contrast, if damp appears on walls, it may indicate an issue outside of your home, such as inadequate plastering or brickwork masonry joints that are not properly sealed. To avoid these costly repairs and protect against further damage from penetrating damp, it’s important to identify any potential sources quickly and rectify them immediately.

In contrast to penetrating damp, rising damp is caused when moisture from the ground below rises up into your walls. This can be caused by an outdated or improperly installed damp-proof course, as well as damage from adjacent structures such as steps, which allow moisture to penetrate porous materials.

Rising damp can also occur when wall construction ages. As walls age and their bricks become more porous, cracks may form in the material, which create pathways for moisture to travel up—this is known as capillary action. Rising damp can quickly become a problem if a wall is built improperly or has been standing for an extended period of time.

"Very happy with the job, straightforward, would highly recommend The London Damp Specialist."

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.

Add to Survey

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.

The survey fee will be deducted from the cost of any recommended repairs.

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.
