Allerton Windows started in 1995 with 4 employees on Sugar Street in Aintree, and has grown to become the largest local independent specialist for replacement windows, doors and conservatories within the Northwest. The company initially sold UPVC fascia, soffits and hardware, however, after Tony Hanratty became the Managing Director in 1996, the focus of the business shifted to installation and manufacture of windows, doors and conservatories.
