    We are absolutely delighted with the new windows – they are engineered to true German standards.

    We now benefit from double glaze sound proofing, the windows are absolutely water-tight and function so much better than our old wooden windows – easy to use and no more rattling in high winds.

    Aesthetically, the house is much improved with the new windows.

    The planning was thoughtful with an eye for details. Our new windows are stunning.

    We feel much safer with the double glazed security glass and the view is amazing without the old plastic burglar bars.

    The PVC Windows block out noise and keep the Cape Town wind out perfectly. They close just like we’re used to from Europe.

    10/10 would recommend.

    You understand building problems like damp and mildew and have sensible solutions.


    You provide quotes quickly and reasonably.

    The work is done to a high standard and, most importantly, you guarantee the work.


    You have been in business for some time now, doing both large and small jobs for us. Many thanks!
