JosTec are a joy to work with.

Nubode Ltd have worked with JosTec for a few years now on several different projects from new build houses to multi unit residential developments. They are a joy to work with! It's always a pleasure to work with like minded, extremely helpful and professional people such as them. Their specialist work is executed well, in a timely fashion and at a very reasonable cost. We recommend them highly and will continue to work with JosTec in the future.

Professional service and quick turnaround

Delighted to have Joe and the team for the soundproofing test.
My new build property has very poor soundproofing, and the team completed the retest professionally with minimal disturbance to my neighbors.
The report is well laid out and will be available the next day.

Acoustic tests on a House conversion

I had Jostec do some sound testing in a house conversion to two flats. They were able to do the testing soon after I requested and they were very polite. The result was positive but even if it hadn't been I had the impression that they would willingly work with the client to resolve it.
