The New Home of ADH Baseline

Including Chem-Lock® and Basetech® products

A long-standing relationship

In early 2019 David Himsworth, owner of ADH Baseline, took the decision to retire after 50 years in the business. ADH Baseline was a family run business that specialised in products for the safe application of pesticides. This includes many products that had been developed in-house over the years such as the award winning Chem-Lock chemical storage box and the Chem-Lock Two Piece Type 4 Spray Suit. PTE had a long standing relationship with ADH Baseline and were thrilled to be offered the opportunity to take over from David and continue to offer the products that he and his son had spent years developing.

Moving forward

In February of 2019 we started the process of moving all the stock to our premises at Doncaster and employed David’s son Richard Himsworth as our new sales manager dealing with all things relating to Pesticide application so anyone who is a previous customer of ADH Baseline will be dealing with a familiar and experienced voice. Since then we have continued to bring ADH and PTE together under one roof and strive to become a one stop shop for everything relating to lawn care, forestry and the amenity industry.

PTE is still family run and things that will not change are the hands-on nature of our business and the personal service that we aim to offer each individual customer. We like to think of ourselves as solution providers and are always available at the end of the phone to offer the best advice we can.
