Advanced NI did a fantastic job. We have an almost flat roof conservatory that regularly leaked. The company promised to do a good job in replacing the roof and they did. A big shout out to Mike (onsite expert), Chris (master plasterer), Davy (master electrician) and all the boys for their hard work. Another shout out to Lee and Jason who sorted out the problem with the bi-fold doors (after all the movement during the build). Every one of the team were respectful, patient and easy to have around the house, however, the roofers' (aka the rubber guys) taste in music is highly questionable. Thanks again everyone. If this review is useful in helping you make a decision, I hope you also have a positive outcome.

We contacted Marty about building a bespoke garden room for our back garden, and from the very beginning, the experience was excellent. Marty came out to measure up and quickly returned with a quote we were really happy with, so we decided to go ahead. Throughout the process, Marty was incredibly helpful and professional. He even brought materials to our home so we could visualise the finish, offering sound advice based on his experience, which really helped us make the right choices. The team started work in early January after the Christmas break, and every single member of his team was friendly, hardworking, and professional from start to finish. A special mention goes to Michael, the main joiner, and Davy, the electrician, both did a fantastic job. If you’re considering a garden room, especially a bespoke design like ours, I wouldn’t hesitate to recommend Marty and his team at Advanced NI Ltd. Gary & Jemma

Very professional company. They installed a new roof on my sun room giving a 10year written warranty. Steven and Marty were great to work with. Their boys came first thing on the morning of the date I was given and completed the job in three days. The old roof and any rubbish was removed. I now have a warm dry sun room. Thank you.

We are extremely pleased with the work completed by Advanced NI LTD. From start to finish, the team demonstrated a high level of professionalism and attention to detail. They installed our, windows, and doors to an excellent standard, and the overall finish has truly improved our home.🫠 The workmanship and reliability were outstanding, and everything was completed on time. We are very grateful for their hard work and would not hesitate to recommend Advanced NI LTD to others.💯

From Jason first came round to measure our Garage Door and Window and give us a great unbeatable quote ( as I had already had others round) until the fitters came round 2 weeks later to remove our old door and window frame and professionally fit the new ones all in a few hours cleaning up after them and taking the old door and frames away we were well pleased with the guys and their work plus Jason the owner came back to view their work and make sure we were happy..id completely recommend this company 100% Will Tate

Had a new composite front door fitted today. Excellent quality and great service guys were brilliant would highly recommend for any job big or small

Delighted with the work done by the team - they replaced nine windows, our front and patio doors in a little over a day in total at a very competitive price for the work involved. Everything was done incredibly professionally and we've already noticed a significant improvement in the warmth of the house. Clean and tidy too - all in all a great company and staff to deal with and would highly recommend to anyone looking to do refurb works. Thanks again!

Hassle free service from start to finish, Ricky and Alex the fitters were fantastic hard working guys friendly tidy and very helpful. The windows and doors are of exceptional quality I wouldn't hesitate to recommend this team to anyone
