Expertise you can rely on
People, History, Heritage
Brothers James and Thomas Allan began their apprenticeship in wood craftsmanship more than 200 years ago, eventually taking over the company from their father, William, when he passed away in 1843.
Their passion for creating the very best in timber windows saw them steadily expand the Berwick factory until it covered an impressive 8 acres. Just like the knots and grain of a good piece of timber, the passion and dedication grew too, and is prevelent in everything we do today.
Peace of mind
Allan Bros’ timber products are designed to look great for years to come. Research has shown that, even with low levels of maintenance, they should last at least 60 years; and with more regular care, can last up to 80 years or more.
