Client testimonials from a selection of our satisfied customers:

We have been using uric xtreme for about two years now in both public and employee urinals and blockages are a thing of the past. We have recently started using the alkaline drain unblocker which has proved a remarkable success. I would recommend these products to anyone on industrial or commercial premises as their use has saved a lot in man hours worked.

Nigel Chant, Network Rail

Brilliant stuff, excellent service & delivery. I would definitely recommend this product.

Bev Harris, Environment Agency

Orpheus was recommended to us by Chemassist for a trial last year, this proved to be very successful in both public and employee areas. We have introduced its application on a regular basis under a Planned Preventative Maintenance regime. We get food and fat washed from plates, hair, chewing gum and tissue in sink outlets plus a few unmentionables! It has reduced our maintenance time, the cost of which far outweighs the cost of the product. Excellent Product.

Nigel Chant, Network Rail

Very happy with your prompt and efficient service.

Dave Porter, Mitie Maintenance

Used the product for the first time and to be honest was a bit sceptical, however, having a urinal that was completely blocked, it was clear within 1 hour - far better than anything I have ever tried previously. Fantastic service from Chemassist into the bargain!!!
