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

First and foremost the service from Chemassist was great. Purchasing online was really easy. COSHH data sheet arrived without request. Product arrived in a very timely manner. The product is just what we’re looking for and worked a treat. It’s so exciting to find something at long last that will unblock a urinal quickly and efficiently. I say exciting because we’ve tried all sorts in the last few years to no avail.

Phil, Bletchley Park

We have the freshest & most trouble free urinals in the area! It is amazing how a regular routine with the right chemicals can eradicate any urinal smell. Great advice on the web site. Excellent customer service. Speedy delivery. Definitely recommend both the product & Company.
