Post-Construction Inspection

Post-construction quality inspection and testing will help to assess the quality of construction in relation to thermal performance, and to determine if the services are optimally commissioned.

We offer a range of inspection and testing services. These include airtightness testing, ventilation performance measurements and thermographic surveys.

Thermographic Surveys

Infrared thermography is an established method for surveying buildings and can provide visual evidence of a range of defects in the building envelope. fourwalls have 15 years of thermography experience specifically relating to building energy and condition surveys. We use our own high-resolution thermal imaging equipment to conduct internal and external surveys to identify areas of greater heat loss and to help identify the cause.

For more information on our thermography services, please download our service sheet here.

Air Permeability Testing

We carry our own UKAS calibrated equipment for undertaking pre-tests on domestic-scale buildings. Although not required by Part L of the Building Regulations, air leakage testing is often useful in existing buildings. This can be of great value for identifying areas that need sealing if it is done in advance of a retrofit.

Ventilation Performance

New ventilation systems need to be tested in order to demonstrate compliance with Part F of the Building Regulations. At fourwalls, we carry a range of our own UKAS calibrated airflow testing equipment to verify the performance of an installation.
