The quality and service of Regency Knights is outstanding! Installed a double roller blind with a block out during summer to keep the sun and heat out but it turns out it actually blocks out the cold temperature generated from the glass windows and screens!! What a great surprise to have. Staff are experienced and Knowledgeable no matter if you are in the stage of picking out the blinds or to the stage of the installation. Will recommend to anyone who is looking for quality and superior product.
