  Replacement of casement/sash windows in conservation area

  We had numerous casement and sash windows replaced with new double-glazed equivalents in a conservation area in North London. Ian and his team have done a fantastic job - able to replicate the old windows perfectly, always on time and very responsive to queries.

  Professional, friendly, highly skilled window replacement

  I Foster & Sons worked at our house 13 years ago replacing the majority of the windows, they came back recently to replace the final window in the bathroom. They are incredibly professional, efficient and provide incredible service. The work is of an exceptionally high standard. The staff are prompt, friendly and very skilled. They are coming back to work on our front door and some patio doors. Highly recommended.

  Lovely team and amazing work

  I Foster and Sons have replaced two bay windows for us and we were thrilled with both. They completely rebuilt our front bay and it's transformed the front of our house, it went above and beyond our expectations. Everyone we've dealt with has been very friendly and helpful and the jobs were carried out quickly and tidily. I would highly recommend them.

  Very Happy Customer

  From start to finish excellent service! Ian was clear, helpful, friendly and straight forward, the quote was comprehensive and easy to understand, the fitter friendly and professional, he protected carpets and furniture and cleaned up after the job was finished. And the windows look amazing, open easily and are exactly what I wanted. I couldn't be happier!

  Great windows and excellent service

  We had 3 sash timber sash windows installed at our house in a Conservation area. Ian was very communicative and incredibly easy to deal with, accommodating our need for planning consent and moving things forward very quickly once we had this and had paid a deposit. We're really happy with the end result, the new windows look fantastic. I would highly recommend I Foster & Sons.

  Great company, excellent communication and really pleased with our new window.

  We were recommended this company by some friends that had previously had work completed by Ian at their house. From first contact through to the installation the communication was excellent, the service overall was great and the installation of our new window went exactly as planned. We have more windows to modernise on our house and will definitely use the company again.
