What Our Clients Say

Royal College of Surgeons

I would like to take this opportunity to thank you on our behalf for carrying out a difficult project extremely well and your workforce are exemplary; completely self-sufficient and self-starting, I only wish all of our contractors were the same. Negative feedback is all too often dished out easily enough so I try to make a point of highlighting when things go well,& your team were first-class. Thanks again.

John O'Riordan, Royal College of Surgeons

We needed a product that could offer us peace of mind for the re-lining of one of our drinking water storage tanks. COVAC did not disappoint.

Clean water is essential for our business and we needed a company who could repair and re-line our water storage tank in order to meet the high expectations of ourselves and our clients. COVAC did an excellent job, with no disruption whatsoever.

I thought that the personnel on site showed excellent knowledge and diligence in advising on the condition of our cooling tower prior to the commencement of work. If it wasn't for that we could have been carrying out a worthless exercise.

The service and workmanship I experienced from COVAC from their tradesmen to their sales and senior management was and is an absolute delight to have worked and work with especially dealing with a very particular client such as RBS and Coutts Bank.  Covac’s before, during and after sales service is bar none and I will always consider, consult or refer them before replacing any of my or any of my colleagues buildings water storage tanks and even any cooling towers.
