Sash Window solutions, headed by Andrew, made the whole process stress free . The timing of the fitting was negotiable and everything was made clear. Questions were answered and concerns addressed The work was done in one day, carpets and furniture protected and everything cleared up neatly afterwards. And the windows look lovely.

Gareth and his team were amazing and professional throughout. He was very knowledgable regarding the options available to us. All work was completed quickly and efficiently. Gareth kept in contact with us throughout our garage renovation and even kept in touch afterwards to check everything was ok for the fitment of the garage door. I wouldn’t hesitate to recommend Gareth and his team and would definitely use them again for any future building work on my home. Great job completed.
