My name is Michael and I have put my passion for windows into creating my business Nu Sash Windows.

We supply and install premium-quality windows, doors, conservatories, and roofing solutions, and we also provide outstanding Renovation Services.

For our premium products, we use timber, aluminum, and iron (for Crittall windows and doors) and will provide you with very competitive prices.

In addition, we aim to beat any written quote from our competitors.

The timber we use is Sapele, Meranti or Acoya (hardwood) double or triple glazed and warranted to 10 years (Insurance backed guarantee with GGFi).

My team and I can also redecorate to a high standard.
