Our whole experience with ERW joiners has been absolutely first class. Our first meeting was a showroom appointment with Stuart Wall, I personally loved the showroom straightaway, the colours of the sample doors blew me away.
To the skilled craftsmen of joiners who made our front door, who we have not met, but who we will forever be grateful too – their craftsmanship is beyond compare – thank you so very much.

We are delighted with the product supplied. The leaded windows look really good and very much in character with the house and with the previous windows. The installation team have been very helpful and informative throughout and are a credit to your company. An excellent job and done exactly as per your contract program (which makes a nice change from some of the builders we have used in the past!). Thank you.

The work of installing our double glazed units has finished and my wife and I want to tell you what a pleasure it was to have the installers working on that job. They had humour, application, care, consideration and skill and we much enjoyed their time with us. We have thanked them but felt it was important for you to know how grateful we are.
Mr & Mrs W, Eaglescliffe
All the staff at ERW have been utterly amazing – from the start of the project, from the general enquiries, to the fitting and installation . I couldn’t recommend this company high enough !
Thank you all so much!
