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. Thankyou I can highly recommend this company.

The sales person, Mark went through everything in meticulous detail. The team who fitted it did it in one day and the price was very reasonable. I was over the moon with this. We have had some bad weather in the last couple of weeks and so far everything seems OK. I would also say the house feels a little warmer already!

Arwel stood out from the other contractors who applied to do the job because he visited before quoting and made some additional recommendations. He replaced guttering, some loose root tiles and also recommended that we use some protective edging that he also installed. Roof looks great.

In total 4 ridge tiles were broken, old tiles kept to show us the fault. New tiles in place and look very good. Extra work requested on the conservatory to fix leaks, still waiting to see if this has worked, but feel confident. A very good job done in the required time.
