Mercury Windows is a small local company that was originally founded in Lansdowne Road Tilbury in 1991. However as of  2013 we have permanently relocated to the Criton Industrial Estate in Orsett. As a company we manufacture and install all of our own products throughout and beyond the Thurrock area. We have completed hundreds of local installations and we pride ourselves on the quality of our work, as the  majority of our newly acquired business is gained through word of mouth.
