All new homes must undergo airtightness testing as part of building regulation compliance. We carry out precise, certified testing to ensure your building meets the required standards for energy efficiency and comfort, first time, every time.

We install a temporary fan (Blower Door) in an external doorway, sealing all intentional openings like vents and trickle grilles.

The equipment creates a pressure difference to measure uncontrolled air leakage through the building envelope.

We provide a full test report showing your air permeability rate (measured in m³/hr/m²), which is required for BER calculation and building control sign-off.

Our results meet national standards and can be submitted to your assigned certifier or BER assessor as proof of compliance.

Below are answers to common questions about our services, processes, and regulatory requirements.
Yes, for all new homes in Ireland, airtightness testing is required under Part L of the Building Regulations.
The test should be done towards the end of construction, once all penetrations, windows, and services are sealed but before final finishes.
We’ll advise you on where the leakage is occurring and how to improve performance before a retest.
Absolutely. Airtightness directly influences your building’s energy efficiency and is factored into the BER calculation.
Yes. All tests are carried out to EN 13829 and ISO 9972 standards by trained, certified professionals.
Book your test today and ensure your building meets regulation standards.
