Finding and fixing issues mid-construction saves thousands of pounds and avoids the headache of failing your final as-built tests. Catch problems before the final finishes go on.
Failing an air tightness or sound test at the very end of your project is a nightmare scenario. It means ripping up carpets, tearing down plasterboard, and delaying handover.
Our part-built diagnostic services eliminate this risk entirely. By testing the building envelope and internal structures midway through the build, we identify leakage pathways and sound transmission flaws while they are still exposed and inexpensive to rectify.
Explore our specialized diagnostic services designed to catch structural and sealing defects exactly when they are easiest to fix.
We depressurize the building mid-construction to pinpoint exact air leakage paths using thermal imaging and anemometers before the walls are closed up.
Explore ServiceBefore starting your renovation, we test how well existing walls and floors block noise. This baseline helps plan the exact acoustic upgrades needed to pass Part E.
Explore ServiceWe use non-toxic, visual smoke generation to clearly locate hidden air leaks or test the integrity of smoke control shafts and shared escape routes.
Explore ServiceWe coordinate directly with your site managers to run tests during the perfect "part-built" window.
We arrange a site visit at the critical "first fix" stage — when the primary envelope is sealed but before plasterboard/finishes are applied.
We use temporary seals and specialized equipment (like blower doors or smoke generators) to simulate the final testing conditions.
We physically walk the site with your team, pointing out, marking, or photographing the exact locations of leaks and acoustic weaknesses.
You receive immediate, actionable advice on exactly how to seal the gaps or improve the acoustic separation before moving to the next build phase.
