We have used SBW on several occasions over the years and always found their services very good, hence I’m a repeat customer. I’ve had bifold and sliding patio doors, front door, other exterior doors and replacement double glazing windows. Quality products, great customer service and aftercare.

Was very impressed both by the service and the product. After a bad experience with a previous window company, which you could feel the draft coming through after one month of instalation, I was skeptical to try different company. I am thrilled I found SBW GROUP. I had my windows done in April 2024 and the quality is above my expectations. The installation team was very organised, professional and considerate and we are very pleased with the results. Highly recommend them.
