The True Cost of Ignoring Damp: What Homeowners Need to Know

Damp is a common problem in many UK homes but it is often ignored or goes unnoticed. Many homeowners and landlords don’t think a spot of damp is anything to worry about. After all, older properties are bound to have issues like this, right?

However, left untreated, damp can lead to much bigger and more expensive issues down the line. Here’s what all homeowners need to know about the true cost of ignoring damp.

Health Risks

Dampness provides the ideal environment for mould growth and mildew. Exposure to mould spores can cause a range of health issues, especially for those with respiratory conditions like asthma. Moulds release spores that can be inhaled and cause lung infections, worsened asthma, wheezing, coughing, eye irritation, and skin rashes. Severe cases can even lead to respiratory failure.

Ignoring a damp problem puts your family’s health at serious risk. If you have children, or sick or vulnerable old people living in your property, it is vital that any damp issues are dealt with as soon as possible.

Structural Damage

When damp penetrates deep into walls and floors, it can cause swelling, warping, rotting of wooden structural elements, and erosion of masonry and brickwork. Damp also corrodes metal components like pipes and electrical wiring, creating an electrocution and fire hazard. Left too long, the structural integrity of the property itself can be compromised. Repairing structural damage due to damp is a huge undertaking that can run into the tens of thousands of pounds. In addition, replacing important structural elements like floor joists is highly disruptive.

Depreciating Value

A property with untreated damp problems will struggle to retain its value and be difficult to sell. Homebuyers are especially wary of damp as the costs to rectify it can be high. Offloading a damp property often means accepting a reduced price well below market value. For homeowners and landlords, it translates to losing a substantial chunk of money from the property’s value and your investment.

How to Fix Damp

Given the severe costs of neglecting damp, taking early action is critical. Here are some ways homeowners can tackle damp:

  • Improve ventilation and air flow with extractor fans, air bricks, and keeping windows open when possible.
  • Identify and repair leaking pipes or faults in the plumbing immediately.
  • Apply waterproof sealants to external walls and use damp-proof membranes when renovating.
  • Control moisture sources by not drying clothes indoors, opening windows or installing extractor dans to prevent steaming up bathrooms.
  • Install a suitable dehumidifier to actively remove moisture from the air.
  • Treat mould growth on walls with fungicidal wash products.
  • For rising damp, have a professional install a damp-proof course.
  • Consult damp specialists if it persists – they can advise on long term solutions.

The costs to health, property, and finances make damp a high priority issue. While treatment can seem expensive, these upfront costs are dwarfed by the amount needed to fix the catastrophic damage that damp can cause if left unchecked.

Acting early and seeking professional help gives homeowners the best chance of addressing damp effectively. Call us today if you need advice.

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.

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

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.
