"We’ve had Nick round 3 times now. The first time, he reset our new front door frame as the previous guy refused to correct his shoddy work. The second time was to put in a new kitchen door and window and last weekend, he installed the final 2 windows at the back of the house, along with a cat flap. Each time, he’s been punctual, tidy, considerate, takes pride in a good finish, competitively priced and we won’t hesitate to have him back for future projects."

"Recommended through a family member, we too couldn't have been happier with Nick's work! He not only installed our windows and bifolds with great precision, but also respected our home during the whole service. Thank you!."

Karen Ainslie


"I would definitely recommend Nick and his team. They have worked solidly and diligently today and in around 5 hours have transformed the front of my house with new windows. They have left no mess, there was minimal disruption and the attention to detail shows in the quality of the finished job. Great value for money too."
