Predictably Find Defects Without Breaching Your Warranty

Act on Independent Advice - Not a Veiled Sales Pitch

Whether you are making repairs or refurbishments, your decision should be based on facts – not on what someone wishes to sell you.  

You also need a housing survey that doesn’t damage the building fabric thereby creating more expensive problems.

IRT uses the latest infra-red technology to accurately measure areas of moisture, leaks and energy loss without mess, disruption or scaffolding.

The thermal images provide hard data – free from the assumption or bias that you risk with a traditional building survey.

Flat Roofing

Find and fix flat roof leaks quickly using a thermographic survey to eliminate the guess work.

Our thermal imaging surveys give you the clearest and most concise condition report of your roofing system to help you identify a flat roof leak. Areas of the saturated insulation have a higher thermal mass when compared to dry, healthy parts meaning problem areas will hold heat for longer when compared to dry areas and therefore reveal themselves, in red and yellow colours, within a thermal image. 

Our thermal reports map out and give clear evidence of these problem areas and the most likely points of ingress allowing you to  carry out targeted repairs, saving time and money.

Having your flat roof repaired?

Thermal imaging can also be used as a quality assurance tool for flat roofing. A survey can be provided before and after a roof replacement to reveal improvements to the system,  putting both your clients mind at ease and displaying the quality of your workmanship.

Underfloor Heating

Accurately determine the position of your underfloor heating pipes and find the source of leaks.

IRT Surveys can provide you with a thermographic survey during an external wall insulation install. The image below reveals a 2 bed semi-detached domestic property before and after the  removal of old timber frontage, application of EWI and  loft insulation. 

Thermographic imaging and analysis  provided within our reports is easy to follow and highlights the clear energy saving benefits of EWI on a property. Because IRT surveys offer a completely impartial service, you and your clients can have peace of mind that the images show evidence of good workmanship.

Fault Finding
Thermal images, within the footer below, were taken a short while after the installation of an EWI system. They reveal warmer temperatures, depicted in red and yellow colours, the most significant of which indicate likely points of moisture ingress at points around the junction detailing.

An IRT Survey is able to assess for failures in the insulation detailing across the entirety of a property, which can allow moisture to bypass the insulation and track along the support system behind. Infrared can show the exact location of any defects and allows for a focused repair operation to be carried out before it becomes and issue.

Cold bridging is a common issue where external wall insulation has been applied. IRT surveys can also detect and highlight and locations where cold bridging is apparent and can compromise the thermal benefits of the system.

What else can IRT do for you?
Survey and analyse large quantities of properties to give estimated CO2 and cost savings upon any energy saving measures applied.
Recommend, where applicable, that a repeat survey be carried out before the end of the retention period to ensure that all issues are addressed and no further issues are present.
Available for domestic and commercial properties.

Predictive Maintenance

Accurately determine whether a piece of equipment needs to be replaced and prevent downtime.

Is your facility running too hot?

Electrical inspections can often be slow and only carried out during downtime or when a failure occurs. Many insurance companies now insist on an annual thermal inspection for compliance. IRT Surveys can provide a cost effective solution whereby we provide a suitable report and information to allow electricians and engineers to carry out repairs.

Companies who practice infrared predictive maintenance regularly check the temperature of critical equipment, allowing them to track operating conditions over time and quickly identify unusual readings for further inspection.

By monitoring equipment performance and scheduling maintenance when needed, we can reduce the likelihood of unplanned downtime due to equipment failure, spend less on "reactive" maintenance fees and equipment repair costs, extend the lifespan of machine assets, and further maximize maintenance and production.

Heat is often an early symptom of equipment damage or malfunction, making it a key performance parameter monitored in predictive maintenance programmes.

Integrating thermography into your maintenance schedule

Infrared thermography cameras are the first line of defense in a predictive maintenance program. IRT Surveys can quickly measure and compare heat signatures for each piece of equipment on the inspection route, without disrupting operations.

Contact us today to find out how we can incorporate planned maintenance into your schedule.

Building Envelope

Impartially locate thermal defects using non destructive test methods. Missing insulation, render issues, porous brickwork and draughts.

Surveying commercial properties quickly and cost effectively can be a challenge. Most are in continual operation meaning access to certain areas can be problematic. A Thermographic Survey can be the perfect solution to determine any regions of weakness in the waterproofing and insulation of a commercial property. Thermal surveying is a form of non destructive testing (NDT) and can therefore be carried out without any risk to health and safety, staff or equipment.IRT can survey commercial properties of all sizes, typically within a single working day. There are a number of services available to help identify issues or give quality assurance.

  • Flat roof leak - Thermal Imaging (IRT) and Electronic Leak Detection (ELD)
  • Window and cladding panel leak
  • Missing/Damaged Insulation
  • Thermal bridging
  • Draughts and cold air ingress
  • Delaminating Render
  • BREEAM Accreditation Credits
    We also carry out general condition surveys which can highlight all of the above defects in a single, easy to understand thermal report.

Considering Refurbishments?
Ask us about IRT Envision, our cost saving analysis report
IRT Surveys can create an energy model of a commercial property and, along with our acquired thermal data, give a real life view of the properties performance. From this information, IRT can provide a comprehensive report detailing the regions of missing insulation and trapped moisture and its financial impact on the property.

Our survey results allow you to effectively prioritise refurbishments based on their ROI.

Housing Stock Condition Surveys

Survey 1000’s of homes quickly using infrared to help prioritise your assets & engage tenants.

Use our bespoke Envision software to determine regions of the property indicative of possible insulation defects. Envision builds 2 theoretical models of the property, one as if it were perfect and another with the identified defects in place. Energy use and CO2 output are determined for both models resulting in each anomaly being quantified for its impact on the building allowing every property to be ranked and rated.

Envision produces an As Built SAP and EPC rating along with an actual comparison, in addition to this Envision also runs a range of "what if" scenarios, such as Roof improvements, improved double glazing, boiler changes, and reports on the impact of each in terms of £s, kWh and CO2 saved per year.

Thermal Drone Surveys

The latest equipment, CAA certified, insured, ITC trained pilots available throughout the UK. Ideal for large roofing projects, unsafe and hard to access areas.

Surveying dangerous unsafe roofs or areas of asbestos can be problematic. Cherry pickers can be used but when a detailed survey is required sometimes they can't do the job. 

IRT Surveys offer the best quality full radiometric thermographic surveys and analysis, whether for roofs, elevations or the whole building envelope internally and externally to allow you to ‘see’ and quantify the building’s defects.

Building Defects: Flat roof leak detection, poor detailing, missing or damaged insulation, delaminating render, moisture tracking, all easily identifiable.

We have full Civil Aviation Authority permissions to operate drones for commercial aerial work – are fully insured – and are experts in gathering aerial images using remote controlled multi-rotor aerial systems, also known as UAV, Drones. We process and edit in-house using the latest commercially licensed post-production applications.

We provide national coverage offering a responsive and personalised service.

We are market leaders in Aerial thermography. We offer an entirely new and unique perspective.  We can get closer, are more manoeuvrable and go where traditional aircraft can’t.
