Core Sash Windows installed our new patio doors recently. First class service from start to finish, I can’t fault anything. The doors arrived a week earlier than expected, and were installed in 2 days. All work was done carefully and in professional manner, and the end result is great. The doors appear very sturdy and good quality. The installers were friendly and professional and left everything immaculate. They even touched up the paintwork and also recycled the old doors. I would be happy touse Core Sash Windows in future and can recommend their services
We had the large sash windows on our 2nd floor flat replaced in a conservation area. The windows are absolutely stunning and have transformed the rooms and the level of finish both outside and inside was excellent. I had not realised how much work and what a detailed task the finishing would be to make it good as new. One of the window sills had to be adapted on site around a unit that we had purchased that was bigger than expected, this was done free of charge and very neatly. The rooms aredraft free and the windows just slide open so smoothly, I wish I had them replaced before. Every member of the team was helpful and pleasant and responded to questions immediately and Core managed to flex delivery to coincide with other building work. The installers were excellent.

We were having major house renovation works and started off with the windows. All the windows except the sitting room were renewed. The sitting room has the old, interior, wooden shutters and couldn’t be replaced with the double glazed units if those were still to work, so these windows were successfully renovated. It was a very happy relationship with Core from start to finish and three years later we are still completely satisfied and happy. The house is warmer and, above all, much quieter.The new sash windows work beautifully. We strongly recommend them.
We ended up going for the basic fit as we were having a number of other work done to the property…In comparison the windows were much cheaper that competitors on the market and this was not reflected in the quality as we still got great windows installed. Highly recommended.
I couldn’t have been happier with Core…They are excellent quality windows, the builders always arrived on time and cleaned up after themselves. The communication and service with their office was always spot on…Very happy to recommend to all.

Three years ago Core replaced some sashes and refurbished others on the back of our Victorian terrace….I had no hesitation in asking Core to return for the front window…I am very happy and have recommended the company to a neighbour.
