Customer Reviews

David Strange | London
Really great job done by Peter and his team. They replaced all the windows in our 3rd floor flat, quickly and matching the old design exactly. Peter provided very helpful advice as to which type would be best for our needs (we went for double glazing with extra accoustic glass) and he also gave us a full break down of the pricing etc. Not at all pushy, just a decent window fitter who did a very professional job. We have already recommended them to all our neighbours and I would highly recommend South East windows to anyone.

Can't tell you how happy I am. Peter fitted french doors and side panels last month for me. Great service from first visit for quotation to completion of work. Straight forward no nonsense, what you see is what you get! Peter worked tirelessly and the level of workmanship was second to none! The doors look fantastic and the finish is perfect! Thank you so much Peter. I will definitely be back for the windows very soon. I would not hesitate to recommend you to anyone. Great quality, workmanship and price!
