Meet the team in Cornwall


From rugged North Cornwall through to the more gentle Southern areas is Brendas territory, encompassing towns such as her home town of Fowey, as well as St Austell, Truro, Veryan and Liskeard. Joining Everest in 1990, shes also responsible for all of our ranges of home improvement products, including conservatories, porches, flat roofs and driveways. Her favourite song is Cockney Rebels Make Me Smile (Come up and See Me). She also has a great sense of humour, so if you book an appointment with her, she could just make you smile too!


Christopher has been with us since 2012, which means that over the years hes introduced many happy customers to our home improvement products, especially in places such as Tiverton, Barnstaple, Taunton, Minehead and his home town of Bournemouth. In his spare time, he enjoys sailing, and certainly lives in a great place to practise it. You can ask Christopher about any of our mainstream products, including uPVC, timber and aluminium windows, and doors in the same materials, as well as composite designs.


Golf fanatic David lives in Penzance, Cornwall. He�??s been selling Everest windows, doors and roofline since 1986, scoring hole-in-ones with customers across his home county, in Falmoth, Helston, Camborne and Truro. David�??s product knowledge is second to none �?? he knows his tilt and turn from his dual turn windows, and his soffits from his facia boards, and he speaks 4 languages, so there�??s no danger of him being lost for words if you need some expert advice!


Lee has been with Everest since 2011, but hes lived in Devon for getting on for 30 years. So he understands the needs of all the different kinds of properties in his territory, which extends to Cornwall and includes Bude, Barnstaple, Ilfracombe, South Molton and Woolacombe, as well his home town of Bideford. All of our main products fall under Lees remit, including alarm systems, artificial grass, roof trim, garage doors and patios, plus windows and doors of course. His favourite album is Pink Floyds Dark Side of the Moon.


If you live in Cornwall and need new windows, doors or guttering, Lee is your man. He�??s worked at Everest since 1982 so knows everything there is to know about our wide range of windows, doors and roofline products. He loves cars - fast ones in particular and enjoys nothing more than zipping around the beautiful county of Cornwall and beyond, to visit his customers in Bodmin, Plymouth, St Austell, Liskeard and Launceston. Lee is one of the best in the business, but don�??t take our word for it. Give him a call and find out for yourself!
