I’ve had two fantastic experiences with Fusion. Tony and his team managed to get our bi-fold doors back in working order. Quick to respond, clear on quoting, and professional and communicative throughout. Highly highly recommended.

Steve / Lou Everett

Tony and his son were absolutely fantastic. Had a bifold where the mechanism had broken and we couldn’t open the doors. Really lovely to find honest, value for money experts who know their stuff. Have done a fabulous job with the repair and doors are like new. Highly recommend.

Ele Marmor

Amazing service. Tony and his son were professional, punctual, reliable and provided a very high quality of work. After using many other companies in the past I will only be using Fusion Window and Door Maintenance Ltd in the future. Outstanding service!
