  • Sash Windows Replacement

    9.75Verified Review

    We've just replaced a number of sash windows with SJB and we couldn't be happier. From the original visit, all the way through to installation we've received excellent communication and service throughout. Our fitters (Michael and Marcelo) were professional, efficient and completed the job within the estimated timeframe. And the windows themselves are fantastic - really good quality, solid build. Thanks SJB!

    An outstanding experience from start to finish. Measuring up and specification process was great. And any queries were handled politely and promptly by the office. And the fitting couldn’t have been better. Jon and Joby arrived promptly every day, made sure everything was protected and then cleared up afterwards at the end of the day. They were friendly and courteous, making sure we knew the status and plans. We had 9 windows and 2 doors, so not a small job. The windows and doors themselves are of very high quality and the fitting is faultless.

    Impeccable, professional service/ outstanding quality. Michael and Marcello, who fitted the windows, were exceptional. Lovely, personable guys with a great sense of humour, but extremely diligent and incredibly hard working. The quality of their workmanship from the fitting, carpentry and masonry was outstanding. I met many window companies before choosing SJB and it came down to the fact that they oozed quality, had fantastic customer service and clearly understood my specific requirements. I am very fussy and have a forensic eye and wouldn’t hesitate in recommending SJB! Look no further!

    Dominic and Rob did a great job and we're delighted with our new windows. SJB, Rob and Dominic were responsive, diligent and the work was of the highest quality. Thank you!

  • Very good experience overall


    Very happy with how it went from the initial sale discussion, to the survey and installation of double sash windows. The team in charge of installing also plastered around the box c. 10c and painted a line on the ledgers outside - so now we only have to sand and paint inside and finish up painting outside for it to look complete.

    Everyone I came across at SJB (Paul, Terry, Jake, Michael, Marcel and Ben) in their various capacities was helpful and expert in their field. My windows and new door exceeded my expectations. The quality of the product and the expertise of the installers is top notch. I would highly recommend this firm.
