A few clients comments

This firm has installed double glazing at our home many times over recent years. We have always been pleased with the quality of their products and the efficiency of their installers. We would recommend them to anyone

I did not realise that companies still exist offering such excellent personal service during the whole process from sales, through installation and subsequent support. An all round excellent family business.

We have had windows fitted by Goatleys before and have always found them knowledgeable and efficient. They offer sound advice and an excellent product. The team they send into our home have been courteous and conscientious.

We are very happy with the service and there was a great range of products. The windows & patio door are good quality. We were surprised at just how well the installers fitted the windows without damaging the surrounding decoration.
