Welcome to JosTec, formerly RJ Acoustics
Don’t worry, we’re still the same people, offering the same great service, we’ve just undergone a re-brand.
When we started as a business we only offered air tightness and acoustic services. Ten years on, the name RJ Acoustics is restrictive and doesn’t accurately represent everything we’re able to offer.
Re-branding as JosTec allows us to continue to add services to our offering that we believe fit in with what we’re already doing, so that we can offer everything our customers need under one friendly, familiar house.
Formed in 2010, JosTec are experts in Building Regulations Testing. We offer Sound Insulation Tests for Building Regulations Part E, Air Tightness Tests for Building Regulations Part L1, Ventilation Testing and Commissioning for Building Regulations Part F, Water Calculations for Building Regulations Part G.
We also offer consultation services, giving you the best chance of passing your testing first time. We have found this to be especially useful for sound insulation testing, where remedial works can cost thousands of pounds.We can also assist with SAP calculations, EPC certificates, Energy Statements and all types of Noise Surveys, ensuring that you never need to look further than JosTec for all of your building compliance needs.Acoustic Testing ExpertsSound insulation testing is required for all conversion and new build domestic dwellings in England and Wales under Approved Documents E.
