Complete window replacement throughout house So glad John patterson was recommended to us by friends tried a couple of big company's but was not a patch on Pattersons Was given a very competitive quote which was a lot better than competitors Work started on time as agreed Pete the fitter was an absolute diamond very hard working always tidied up at end of day and anything we did not understand he took time to explain/ show what he was doing before starting work All in all absolutely over the moon with the finished result and highly recommended - May 2020
