I've been dealing with Zammit for 20 years now and have never had an issue. Rainier, Joseph and the team have many years of experience between them and that shows when it comes to advice. The staff are always friendly and helpful when needed. Will definitely be coming back for more supplies when needed.

Great friendly old school customer service, sales staff was very knowledgeable and was able to assist me with my complex enquiry. I recommend physically heading over there if you have any custom flashing or barge cap requirements, they can basically make anything and very quick order turnaround.
