Precision workmanship delivered with exceptional customer service
Mercury have just completed a full refurb of my home and their products, service, communication and fitting was absolutely superb. From the first consultation to the final fitting - everything was seamless. This company is a credit to the fenestration industry. Would highly recommend them.
Started Using Mercury back in June 2020 when my previous supplier was unable to fulfil any orders on time and i can honestly say i wouldn't change suppliers! In the current climate you have to expect a few supply problems but Mercury staff went out their way to accommodate any delays from profile shortages. Products were supplied to a very high standard and all my customers are over the moon! Very happy and have recommended to many friends in the trade. S.A.Palmer
