  • New windows on 1st and 2nd floor

    10Verified Review

    Sashwise were fantastic. They very clearly explained the options before quoting and gave clear timelines ahead of installation. The team on site were brilliant - very courteous and with minimal mess given the job. Our new windows look fantastic and make a huge difference to the warmth and appearance of our house. Would highly recommend.

    Sashwise were absolutely fabulous. They visited us quickly upon our first query, sent a quote very promptly and all work was undertaken in the time frame set out. Melissa and Dan were very nice to deal with and the fitting team - Tim Jay and Zach - were friendly and tidy. The finish is beautiful, and for a reasonable price too. Thank you!

  • Replacement of single glazed sash windows with double glazed sash windows

    10Verified Review

    Sashwise did a marvellous job of replacing our badly fitting Victorian single glazed sash windows with identical double glazed sash windows. The new ones are stunning and make a huge difference. We went for conservation/slimline windows which look very in keeping with our early Victorian house - you can't tell they are double glazed as they are so slim. They suggested keeping the original boxes so that saved money. The team were very neat, tidy, quiet and considerate, even working around our 14 month old baby's nap times! We will be using them again for the rest of our windows in due course.
