The Advanced Group 

Just had new doors and windows fitted by Paul and John They were excellent. I hate workmen in the house but I would have them back any time. Very clean and tidy. Nothing was a problem to them.

Terrific work ethic extremely pleasant and really efficient. John and Kieran

Had my windows fitted by Advanced Group 4th-5th July 2023, they fitted 7 new windows, was raining on both days but the young men John and Kieran stayed cheerful throughout both days, I can only speak highly of them as very quick clean and hard workers, Would recommend the company to anyone who asked who installed my windows,and also like to say Siobhan who took measurements and went through different window designs very pleasant. Thank you all.
Kind Regards, Mary Elizabeth Long.

Just had Paul & John from The Advanced Group fit 10 windows to our house. They were professional, polite and did a first class job. There has been a mix up with 2 windows which Advanced have promised to fix and I have used them 4 times now in the last 6 years and they have always been good to their word. I have to say Paul & John are an asset to the Advanced Group. Great job guys thank you.

Just had a new composite door fitted and can't praise Advanced Windows and Doors enough.
James from sales was very professional and his knowledge of the products was amazing.
Also fitters were really great and very tidy.
All in all would definitely recommend.

Had a replacement door fitted. Very impressed with the quality of the door and the workmanship of the fitting team. Meticulous in their work, clean and tidy and the finish is perfect. I was so pleased with it that I have now ordered a new window. No pressure selling.

We have just had an outstanding experience with the Advanced Group and would highly recommend this company - they are the best in business!

From our initial visit to the showroom in East Kilbride, the planning and design of the windows, the visit to measure up and the fitting, we are very pleased with the end result.

With 30+ years behind them, Mark and the team are incredibly knowledgeable. The showroom was very impressive with whole team delivering an incredibly high standard of service.

The weekend of fitting was fantastic, Alan and Kevin were very well mannered and had a great work ethic. Our home was immaculate after the work was completed.

We are so pleased with the end result, the windows have transformed our home and have been admired regularly since being installed.

Fantastic service and we would highly recommend the Advanced Group to all of our family and friends.

Had my front windows replaced with triple glazing, by The Advanced Group. Nicola was our first contact who ensured everything went speedily and smoothly.
The fitters were David and Sean who were fantastic. No mess and great workmanship ... they didn't even damage any tiles which were tight up against the old frame.
I'm looking to get my back windows replaced soon, hope to use Advanced again.

Had a fantastic experience with The Advanced Group. I saw the advert on tv and although I had another company in line I contacted them- Siobhan provided a straight up and honest demonstration and I agreed to go with Advanced immediately.
John and Kieran did a brilliant job fitting my new windows- they did my 3 bedroom flat in about 7 hours - and Kierans a whizz with the hoover...
I'm delighted with the new windows and the service throughout.

We had new windows and doors fitted by Advanced Group. We called into the showroom in East Kilbride where we met Siobhan right from the start we felt positive about this company. She gave us excellent information about their windows and doors explaining our options but with no pressure. The fitters David and Sean were excellent. We’re delighted with the job and would not hesitate to recommend this company.

Just had a new conservatory installed by William & John. Absolutely delighted with the result & wouldn't hesitate to use this company again & recommend to others. The guys worked non stop, left the site tidy & nothing was too much trouble. How refreshing to have a company with a first class work ethic. Thankyou.

Very happy with our new windows.

Siobhan Hancock was very knowledgeable and explained everything very clearly.

Really great experience from the advanced group. Siobhan was friendly, efficient, and accommodating. John and Kieran installed the windows and doors diligently and were happy to answer all my questions. The house looks smashing. Very, very pleased with the end result.

Positive experience with Advanced Windows. Siobhan has been excellent throughout, from her first visit to discuss the job and agree a price, right through to the after care once the window had been fitted. We installed a very large unit over four sections with a big slider opening to the back garden and the whole unit is stunning. What a difference.

Fantastic company from our first visit to the showroom to the day of fitting, Siobhan came out to measure and advise re best type of Windows and Patio doors for us , very informative and interesting demonstrations .

The day of fitting went without a hitch and Robert and John were excellent they left our room spotless and they well mannered and hard working. We are absolutely delighted with our purchase and so glad we chose The Advanced Group
