Anton and Scott were fantastic. They gave us good advice on what we needed to do and what we didn't, which saved us money. They fitted a new window for us which looks fantastic, repaired hinges and handles on others, replaced a couple of panes where we needed it, and were friendly and professional. Would definitely use again, and recommend them.

Anton from NAG Windows was very helpful and quickly sorted problem with our UPVC back door that we had been trying resolve for years. He came out very quickly after posting job,although he was not local and was very helpful throughout and quickly adjusted door to make it serviceable again for the time being after original bodge job by the original fitter damaged the hinges.

Very happy with the work done by Nag windows. Rather than trying to rip us off they gave us good advice and did a great job. Will look to use Nag windows again for future work.
