Excellent service from start to finish for fitting bifolds. Good communication, polite and courteous. Installation trickier than initially thought but were able to resolve as well as meet timescale and budget.

Beautiful windows, brilliant service and all at a fair price. Leigh & Gemma were fantastic from start to finish. Living in an old property we were skeptical about moving away from wood but the upkeep was too much, so decided to move to an alternative. Leigh knew exactly what product to use and install was perfect. Clean & tidy and finished to a very high standard, we think you’ll agree that they look sunning and it’s very difficult to tell that they arnt wood!

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.

Absolutely excellent! If I could give a ten star review, I would! (To anyone with any experience of builders/construction etc you’ll appreciate what a rarity that is!!) Leigh has just replaced all the windows on the front of our house and fitted a new front door and we couldn’t be happier. Gemma was fantastic at keeping us up to date on the progress of the job, from organising the initial quote to delivery & installation. Leigh was absolutely brilliant, a proper grafter! Arrived on time every day he was with us and got all of our windows and doors fitted PERFECTLY. His work is so neat we have virtually no making good to do at all. Everything looks fantastic, the impact of outside noise and warmth of our home was instantly improved! The price quoted was very fair and competitive, we would not hesitate to recommend LB window Systems Ltd to anyone. Brilliant. Thank you Leigh & Gemma!

Service was brilliant; Leigh turned up when expected for the quote and Gemma was excellent at providing information throughout, from quote through to updates on delivery and installation. In the day, the installation went brilliantly, even though on of the windows was more difficult due to the previous window being fitted badly. Leigh talked me through everything they were doing and even repaired all the blown plaster caused by the previous window. New windows look fabulous and I’m so so pleased with noise reduction of the road – glad I took Leigh’s advice!

I would highly recommend Leigh and his team. They recently replaced all of my windows and doors and installed bi-folds at the back of my house. They provided an excellent service with great communication. They were on time, unbelievably efficient and totally professional.

The workmanship, attention to detail and overall finish provided by Leigh and the whole team is absolutely first in class. I could not be any happier with the overall experience as well as the end result. I would have no qualms whatsoever in recommending LB Window Systems, in fact if you can manage to secure them to install for you, you are incredibly lucky!
