Our Equipment
Damp Meter
Purpose:
Takes comparative surface moisture readings across accessible walls, floors, ceilings and building joinery.
Common Uses / Notes:
Maps surface moisture profiles to help identify rising damp, penetrating damp, condensation, or active plumbing leaks.
Deep-Penetration Damp Meter
Purpose:
Detects moisture changes deep below the immediate surface of structural materials without destruction.
Common Uses / Notes:
Evaluates dampness within wall cores, beneath floorboards, inside subfloors and behind finishes without removing plaster.

Best For
This survey is best for customers who need a damp and timber inspection. It is suitable where there may be concerns about damp,
wood rot, dry rot, wet rot, woodworm or moisture hidden behind building materials.
The Level 2 Damp Survey uses equipment that can read deeper into building materials, including areas such as subfloors, under
floorboards, behind panelling and other accessible hidden areas. This allows us to get a better understanding of whether there may
be hidden damp within the property without dismantling or damaging materials.
This survey is very suitable for home buyers and sellers who want a more detailed damp inspection before purchasing or selling a
property.
Level 3
Advanced Building Moisture Survey

Best For
This survey is most suitable for home buyers, sellers and property owners who want the most thorough damp inspection available. It is ideal where there are concerns about damp, leaks, mould, condensation, ventilation issues, timber decay, hidden moisture, roof defects or general property condition.
The Level 3 Damp Survey covers all key areas of the property, including walls, floors, ceilings, ventilation, drains, plumbing, timber, hidden areas and roof-level defects. It is designed to identify damp and moisture-related issues that may not be visible during a basic inspection.
This survey is especially useful for buyers and sellers because it includes a 4K drone inspection of the roof, chimney stack, guttering and other high-level external areas. Roof defects are one of the most expensive hidden issues in a property, and many roofs, chimney stacks and guttering systems are not 100% perfect.
The extra cost of this survey can often be recovered if a roof, chimney, guttering or high-level defect is found before purchase. Even a small issue found on the roof can cost more than the difference between survey levels. Roof problems cannot usually be ignored, as water ingress from above can lead to serious damp, timber decay, internal staining, mould and ongoing property damage.This survey is best for customers who want a detailed, evidence-based inspection before making decisions about buying, selling, repairing or maintaining a property.
Specialised Laboratory Diagnostic Add-Ons
Add-On 1
Laboratory Analysis of Plaster Samples
Price £299 + VAT
Small plaster samples are carefully taken from affected walls and submitted to an independent laboratory for salt analysis. The laboratory tests for the presence and precise concentration of hygroscopic salts, including nitrates and chlorides.
Diagnostic Value: Soluble ground salts are drawn up through masonry during rising damp and remain in plaster permanently. Salt analysis scientifically differentiates true rising damp from condensation or historic leak contamination.
Note: Plaster sampling requires minor material removal and is our only add-on involving minor invasive work.
Add-On 2
Mould Laboratory Testing & qPCR DNA Analysis
Price £299 + VAT
Surface swab or lift samples are submitted to an accredited laboratory for advanced qPCR DNA analysis.
Diagnostic Value: Accurately identifies exact mould species, measures contamination concentrations and detects hidden fungal growth inside cupboards or behind dry lining. Delivers impartial scientific evidence to guide safe environmental remediation.
Add-On 3
Gases, Chemical Vapours & Airborne Particle Testing
Price £299 + VAT
Comprehensive environmental air quality and gas screening tailored to specific property concerns.
Screening Suite Includes: IAQ air quality assessment, Volatile Organic Compounds (TVOC/VOC), Formaldehyde (HCHO), Particulate Matter (PM1.0, PM2.5, PM10), Sewer Gases (H2S, NH3, CH4), Combustion Gases (CO, O2) and ventilation performance.
Diagnostic Value: Air quality issues are often linked to damp, leaks and mould, but they cannot always be identified by a visual inspection alone. This testing helps detect hidden airborne contaminants, gases, chemical vapours and fine particles that may affect the property’s condition and indoor environment. It can also help identify problems such as poor ventilation, sewer gas ingress, off-gassing from building materials, combustion-related gases, or airborne particles following water damage, providing a more comprehensive understanding of the property’s condition.
It is also useful where a property has persistent unpleasant or unexplained odours. The testing can help investigate foul smells caused by damp, water damage, stagnant water, drains, sewer gases or chemical vapours, allowing the source of the odour to be identified more accurately.
Testing includes:
- Indoor Air Quality Testing- IAQ
- Volatile Organic Compound Testing- TVOC / VOC
- Formaldehyde Testing- HCHO
- Fine Particulate Matter Testing- PM1.0 / PM2.5 / PM10
- Dust and Smoke Particle Testing- PM1.0 / PM2.5 / PM10
