Great job and quality product

From the initial contact with AGS, Andy turned up on time and very knowledgeable and went through the product and our requirements, which was very useful and we changed our opinion, for the good, on a couple of things. We agreed price, surveyor turned up within a week and windows were ordered. The fitters turned upon time, were punctual, tidy and professional pleased with the fitting. I have already recommended them and would have no issues with using again, if need arises.

Friendly people, good response and communication but I only had 2 windows done and one looks wonky next to the other so disappointed. No remedy suggested

The trader replied (on 26/02/2018)
Thanks for your comments Phoenix. I am sorry that you are not happy with the appearance of the two windows, however, as per our email to you, your front wall has subsided and the two brick openings are now not level or square to each other. Our windows must be fitted level and square though, so as the windows open correctly and locks operate properly. I am afraid that this is the reason they look wonky next to each other. The only remedy would have been to demolish part of the front wall and for builders to rebuild the wall and form two new brick openings and install new lintels above the windows. The cost for this type of work would have been in the many £1000s and therefore cost prohibitive. Not only that, you did state to Gavin, your installer, that you were aware the original windows were also out of level to each other. We do have 23 photos of before and after the AGS installation, just in case you needed them for reference. Please do get in touch if you need anything further from AGS. Regards. Andy

This is the 2nd time we have used AGS and they were as brilliant this time as the last. Every aspect of their work from survey to completion was outstanding. It's refreshing that a company like this still exists in this day and age.
