What our customers say about us 

“I am happy to give a reference to Supreme Lock & Hardware. SLH is always very approachable, and makes ordering, supplying, and installing hardware on my projects a very smooth and stress-free process. Whilst having the capabilities of scheduling appropriate hardware for jobs without these details given by the architect, they are also able to supply and install. This is very helpful on design and builds projects especially. SLH is generally competitively priced which is a real bonus when dealing with tight budgets. SLH is a pleasure to deal with and I hope to continue to use them for the foreseeable future where I can.”    John Downes – Watts & Hughes Construction


“The team from Supreme Lock & Hardware has been my top pick for a hardware contractor on my projects for the last 3 years. This is mainly because of the streamlined service they deliver. If a problem occurs onsite, they inform me and get it sorted as soon as possible to prevent delays to the program. We have formed a good working relationship and any pricing required comes back promptly and fairly. Keep up the good work.”  Josh Mather - Watts & Hughes Construction

 “I have dealt with SL&H on numerous tenders and I have found them great to deal with. They always have a fast turnaround time on tenders which is a huge plus for us as the main contractor. Supreme Lock & Hardware always has an eye for detail and makes sure nothing is ever missed when tendering and delivering the works. “    Tasmin Burt- Marra Construction

  "We have been dealing with Supreme Lock & Hardware for the last 12 years for all of our hardware needs. Throughout this time they have provided us with an excellent service. They have a very good knowledge of their products and regularly provide us with great advice. Hardware is often an item that is not specified correctly within the drawings & specifications, so Supreme Lock & Hardware regularly help us in providing a schedule and price for a project. The option to install the hardware is a great addition to their service. This combined with a very fair pricing structure makes Supreme Lock & Hardware our No 1 preferred supplier for our hardware needs."  Anthony Hawes - Hawes
