For many years, Alan Titchmarsh has transformed some of the toughest backyards in the uK to help people realise their dream of owning a beautiful wow-factor garden.

In “Love your home and Garden” Alan and his expert team create brand new indoor spaces to compliment the amazing outdoor spaces. To this end they work with carefully selected partners with expertise in their chosen field.

Insulating Windows, a leading Hertfordshire ‘Which’ Trusted Trader and ‘Checkatrade’ double glazing installer, were delighted when they were approached to be a part of the programme. They were asked to assist in the installation of a window and door combination for a family in Hemel Hempstead.

The prospect of helping a deserving local family was very appealing for Insulating Windows whom have had a long 30-year plus trading association with the hemel area. In that time the business has installed in excess of 20,000 orders.

The program was aired on Tuesday, 16th October 2018 on ITV when the house was revealed to the deserving three generations of family that lived under that roof.
