What our Customers Say

An exceptional company that rescued us when another rental company had let us down. We have been able to get equipment delivered at short notice thanks to the team’s expertise and promptness. Highly recommend this company.

David Mills

The Trelawny 2ft Long Reach tool I purchased recently is great because it’s just as powerful as the electric tools, but as it’s air-powered, it can run continuously without needing any breaks.

Ian Harrison – Harrison Plastering

Productivity has exceeded our expectations. The tools are very robust plus we had a higher yield which increased our usual productivity by 50%
