Replaced all windows and doors in four bedroom detached house

I contacted The Advance Group East Kilbride with a view to replacing all windows and doors in my detached house. The salesman Harry was very knowledgeable and answered all my questions about installation. We had a bay window in our living room which I wanted replaced with a flat window and this was carried our quickly and expertly. I also needed some plastering work and a couple of minor adjustments which were done by appointment after the installation. I am really happy with the quality of the windows and doors and the workmanship and the property is noticeably warmer. I am delighted that I chose this company and would definitely recommend them. The installers Richard and Jason were excellent.

Extremely disappointed. I had new windows and a door fitted to…

I had new windows and a door fitted to the sum of 13k, initially the door didn’t seem to seal properly a surveyor came out and said it was fine. We had white shutters fitted then noticed from the outside they looked green apart from a middle bay that was clear glass and the shutter looked white. Surveyor came back and agreed the glass was green tinged and said he would replace, he checked the door again and said a hinge was broken, he checked the silicone on the inside as we told him it was tackie and he agreed it hadn’t set. Eventually the staff came with new front window glass which is still green and the fitter agreed it was still green, they where meant to cut the silicone out but just cleaned it and skimmed over it leaving a bit of a mess and told us the door needed 3 new hinges and still not fixed. We have had to do the chasing, they have never followed up once, we’re still waiting on them to call us and were extremely disappointed.

Good afternoon Jackie,

Thank you for your detailed feedback, and we’re genuinely sorry to hear that your experience has not met your expectations. We understand how frustrating this situation must feel, especially after making a significant investment in your home.

Regarding the glass, we’d like to clarify that all of our glazing is high-efficiency, which means it naturally has a slight tint - often a green/blue hue. This is not a fault but a normal feature of energy-efficient glass, designed to improve insulation and reduce energy bills. We aim to explain this during the process, and we’re sorry if this wasn’t made fully clear from the outset.

We also acknowledge your concerns about the door, hinges, and the silicone work. Our surveyor’s visit and the subsequent actions taken were intended to resolve these issues, and we regret that you’ve felt the need to chase for updates rather than being kept informed proactively. That’s not the level of service we strive to deliver.

We are currently reviewing your case internally to ensure any outstanding issues are fully resolved and to prevent similar situations in the future. A member of our team will be in touch shortly to discuss next steps and bring this to a proper conclusion.

Again, we sincerely appreciate your feedback - it helps us improve. If you have any further concerns or would like to speak to someone directly, please don’t hesitate to contact us.

Kind regards,



Gordon

Good morning Thomas,

Thank you for taking the time to leave a review and please accept my most sincere apologies.

I will feed this back to our sales manager and ensure appropriate action is taken as this is not how our sales team should behave.

I would be grateful if you could give me some of your time and give me a call on 01355 266 889 to discuss and see if there is anything to make it right.

Kind regards,

Highly recommended

Stephen and Donald did the fitting of my new front door. Their workmanship and attention to details was exemplary, their attitude and professionalism was highly commendable and their clean-up and customer care was superb.

My whole experience with Advanced Group from sales, surveying, the quality of your doors and the fitting has been perfect throughout. I will be recommending your company to family, friends and neighbours.

Excellent service

Service from start to finish was excellent. We were looking for 2 external doors to be fitted and Nicola came out to discuss our options. There was no pressure to purchase and she equipped us with all the information to enable us to make an informed choice. Told us how the process would work and provided us with suitable install dates, no issues and install was very smooth. Very pleased with our new doors and wouldn’t hesitate to use the Advanced Group in future.

New door

Just had new door installed. Service has been superb from the moment we made an enquiry. Within 24 hours, Nicola had made contact and provided us with an informal quote, confirming our choices before sending us a formal quote and contract very soon after. Installation was quick and the workmanship seems excellent (left the area in a better condition than he found it). The price was very competitive. I would highly recommend The Advanced Group. Thanks Nicola and team!

Sale and instalation of new windows and doors

From the initial order to the instalation all went very smoothly. The instalation boys Paul and John were brilliant and very professional and proficient. They works extremely hard in very warm weather and we're excellent as was the finish and the products.

New windows.

Meant to write a review before now.
Paul and John fantastic job guys. Really appreciate all you did for us.
Absolute grafters. Didn't stop. Not even for a cup of tea.
I was expecting a mess to clear up. But they cleared everything up as soon as they finished the job.
From start to finish. Stephen organised our job to be done 23rd and 24th July. Surveyor Graeme followed up after that and suggested a couple of changes. Which we're really happy with.
Paul and John arrived exactly when they said they would.
Love our windows and can definitely recommend Advanced Group.

Nicola in sales was great

Nicola in sales was great, very patient as I had a delay in confirming the order and then a delay to the install date from my end. This is the second time I have used the company (previously in 2007 at a previous address) and I fully recommend the product quality, customer service and installation experience from Advanced Group. A+

Excellent

Nicola sales rep was very helpful. It was a no pressure conversation but her knowledge of all the different options was exceptional. I decided to go ahead on the same day. Lead time was a few weeks due to bespoke nature of the work, but the install crew were super professional and the finish perfect. I have deliberately waited 3 months to write this review and can confirm all is still working perfectly with zero issues

You get what you pay for

We recently moved to a new house and decided to replace the existing windows and doors as they were old and needed updating. After some research, we called Advanced to arrange a quote. Received a callback quickly to arrange a suitable date to get a quote.

A few days later, Derek came out as arranged and talked us through all our options. Very knowledgeable and friendly. He also suggested that we pop into the showroom to see the products we were talking about before committing to anything. Later that day, we received our quote via email with pictures of each product we were considering.

The following day, we went to the showroom to see the style of windows and doors we were going to have installed. Again, all staff were very friendly and after a few adjustments were made to our order, a full survey was arranged, along with an installation date a few weeks later.

2 days later, the detailed survey was carried out and the surveyor walked through each product with us to make sure everything was as required and talked us through a couple of things which would be done to make sure everything fitted perfectly.

A few weeks later, as arranged, work commenced. Installation took 3 days due to needing 6 normal windows, 2 doors, French windows and a huge front window. The 2 lads who came out to do the work were friendly and hard working, they hardly took a break throughout the entire installation and were happy to answer any questions we had during the job. The work was completed to an extremely high standard and they tidied up after themselves each day.

Overall, I can say that The Advanced Group may not be the cheapest option but they are the best. Like the title says - you get what you pay for and we are delighted we decided to go with them. I would not hesitate to recommend them to anyone.

Nicola our sales rep was informative and pleasant to deal with. Quick install date, fitters arrived on time, cleaned up afterwards and fixed an issue we had with our front door. Recommend Advanced group. Great experience from start to finish.
