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.

Paula Adams | London
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!

Zaf K | London
High recommendations for Southeast Windows. Roy was a pleasure to deal with and was always happy to assist with his extensive experience in the industry which really shows though. Would definitely recommend Southeast Windows to all friends, colleagues and family. Roy done an excellent and professional job with no pushy sales and great aftercare along with honest and upfront advice and assistance- what else can you ask for? Thanks again.

Terry March | London
Very happy with Roy and his team who fitted a front door, patio doors and windows throughout the house. All great quality and a lovely finish. Would highly recommend this company from the very first visit to the end result they were very professional and left no mess.
