Great product and great staff
To start with the sales rep Hayden was a pleasure to deal with and came in within our budget range A Pallido door 10 new windows and a sliding quiet close back door A small wait of a couple of weeks and the 2 fitters were lovely explained beforehand the job would take 2days i work from home and they did all they could to accomadate me being there while the work was being done The boys cleaned up after each day and the finish product was better than we thought it would ever be We had an awful issue with the house being cold no longer an issue the windows are open everyday The windows and doors are perfect Will be using this company again in the future 5stars
