Hi All Plasta, just want to say a huge thanks to yourself and the Allplasta team for the delivery we received on Friday. You were most helpful with communication, the website was straight forward and easy to order through, the guys that delivered it were friendly and careful, the delivery was super speedy and most importantly the coving looks amazing and is of amazing quality. I'll be sure to keep you guys in mind if I ever need anything in the future and I'll recommend you to my friends that are also renovating.
Thanks again and kind regards.
