We heard an advert on the radio for IQS. We gave them a ring and shaun came round to get us some prices for replacing 2 bay windows. Unbelievably he told us that he would not be charging us a penny and all he would be doing is getting us some quotes for replacement windows. When Shaun came back to us with the quotes they were fantastic!! We saved over £4000 compared to our previous quotes!! The windows have now been fitted and we are over the moon. We would highly recommend using IQS.
