Excellent service from a great company
Ordered 2T of midnight blue slate chipping (2 pallets of 50 bags each) Very nice product at a great price. Contacted quickly after order to arrange a suitable delivery date. Delivery was as arranged. Customer service is excellent including follow up call to ensure everything went well. All in all I would highly recommend Armstrong Cheshire.
Great Customer Relations
Due to a mistake in communication ( mostly my mistake) the first delivery of bulk aggregate went to an address I used to live at. After asking to have a replacement delivery to the correct address Armstrong Cheshire re-scheduled the delivery within 3 days and with fantastic customer relations. I cannot recommend this company enough.
