Jayne Raywell

After having new windows installed in August this year by a company who basically wrecked the front of our property with the wrong size windows with no support, resulting in the front sloping away from the house and all rendering cracked, I called Paul at Pro-fix Windows 07930 330838. Paul and Adam attended our property and assessed the damage, (IT was really bad). Paul and Adam agreed to do the work and what can I say! They have totally transformed the house (please s). The quality of the new windows is far superior to the ones that were installed in August they was a so bad... they have done a totally amazing job. We cannot believe how nice it looks from how bad it did look. I never write reviews, but I simply had to for this service. They were there every single time on the dot as agreed and the details of the work is 1st class. if I could give 10 stars I would everything is top of the range, clean, tidy and very hard working and when we look at the front it’s like a totally new house. Thank you so much, if you need new windows you will not be disappointed with Paul at Pro-fix Windows. Thanks guys for your amazing work definitely a 10* Rating
