Before we apply an external render, we can install your EPS (expanded polystyrene) insulation boards, which will have a thermal insulation value of at least 0.038W/mK.

This will also help to reduce sound transfer and reduce condensation on internal walls, helping to prevent damp, which in turn has health benefits.

"In a word, fantastic! I was expecting it to be good but the finished product was even better than expected. It truly looks like a new house and it was built in 1949!"

Mrs A

"SJRendering were very reliable and produced a very good job. I would definitely recommend them. Stewart and his team worked very hard and our bungalow looks great."

Mr W

"Stuart and his team have recently fitted exterior wall insulation to my home. They fitted it efficiently and as quietly as humanly possible. They turned up when they said and worked as long as possible each day. The work was beautifully done and finished with no mess lying around. The insulation has made no end of difference to my home, raising the temperature inside, which was what I was hoping it would do."
