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.

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.
