Hi had really great service from LB window systems . I had been recommended by my neighbour who had used them over a number of years. I had 12 windows back and front doors fitted and I must say had a 100% positive experience. Leigh, Gemma and everyone I had contact with over the order and fitment process where friendly professional and kept me informed every step of the way. I did have a slight problem with one window mechanism which resulted in another visit. again this was dealt with swiftly and with no drama. I have already recommended LB to friends and family

Leigh and his team replaced our front and back door, and installed a bifold and full length window. The workmanship is great, the products are good quality and they were friendly, punctual and tidy. We wouldn’t hesitate to recommend them.

Recently had all the windows on our house done by LB Window systems and the difference is just incredible! The house looks so much better, service provided by Leigh, Gemma and the team was brilliant, from quotes to the work being carried out in a clean and professional manner. Can’t recommend this company enough, thank you again!

This is the second time we have used LB Window Systems, having used them last year to replace windows and door on a garden office and been very pleased with the results. This time it was to replace the front door, windows to the front of the house and patio doors at the rear. Leigh and Gemma were very helpful and responsive from the outset, pulling together numerous iterations on quotes to help us get exactly what we wanted within our budget. Five star from start to finish including the results and service. We’ll be using them again when we finally get around to doing the rest of the windows and cannot recommend them highly enough.
