How long your aluminium windows will last depends on their quality. They should last 20 -30 years at least, but have been known to stay in good condition for up to 45 years. This is considerably longer than uPVC and wooden double glazing.
Harwich
Harwich is a town in the English county of Essex. Found on the coast in the Tendring district, it is near Felixstowe, Ipswich, Colchester and Clacton on Sea, and it is the most northern seaside town within Essex. Because of its position on the estuaries of the River Stour and River Orwell, as well as its benefit to seafarers as being the only safe anchorage in between the Thames and the Humber, the town had substantial civil and military maritime value for a long period of time. In 1657, the town became a naval base and was highly strengthened with the construction of the Harwich Redoubt, Beacon Hill Battery, and Bath Side Battery. According to the 2011 Census, the town has a population of around 17684. Despite the fact that it is a town of a fairly modest size, Harwich has a high track record for its architectural heritage. The town continues to be structured using the conventional street plan incorporating principal thoroughfares joined by a variety of small alleys, which indicates the town's medieval origins. The majority of the existing medieval structures are private homes, although there is a range of public structures of a historical nature. This includes the parish church of St. Nicholas, built in 1821 in a Gothic style, which contains much of the original home furnishings and an organ. Only one structure is Grade I listed, which is the Guildhall of 1769. A striking building is the Pier Hotel of 1860, renamed the Great Eastern Hotel of 1864, which is a stunning demonstration of the town's changing role after the arrival of the railway line in Colchester, attracting increasing numbers of visitors.
