What customers say

Based on genuine customer reviews

PVC windows, composite and patio doors, and garage doors form the core of the work Millar Windows and Doors carries out for households across Glasgow, and reviewers return to the same themes when describing the experience. The initial visit and quotation are handled by George, who more than one customer describes as thorough and unhurried, measuring up and providing a competitive price without any pressure to buy.

Once an order is placed, Denise keeps customers informed through to completion, a point of contact that is mentioned repeatedly for its steadiness. Fitting is carried out by Stevie and John, named often for their courteous manner, their efficiency in completing jobs within the agreed timescale and their care in clearing away all rubbish and leaving the property clean. A recurring observation concerns the standard of the finished work, with composite and Rockdoor entrances, PVC windows and replacement doors described as neatly installed and finished to a high quality, including the handles and letter boxes.

Advice on design, materials and colour choices is another theme, with customers noting that questions were answered patiently and nothing was left unexplained. Repeat business is common, with some returning for further doors or windows after earlier installations, and the workmanship of the fitters, particularly Stephen, is singled out for its neatness on more than one occasion.

Great company to work with. Quick message exchange, appointment to measure sorted, very competitive quote for a replacement door. Contract agreed and order placed, 4 weeks later new door fitted. The quality of the door and fittings are first class. The fitter Stephen was excellent and his workmanship an example to all tradesmen. So good I’m already in the process of getting my windows replaced too. Thoroughly recommended.

Was worse thing I did was get them to look at my 89yr Dad’s door lost count of many times George the owner! Came out messed around with it!! Was asking an absolute fortune to replace a new PVC door with the old mechanism in it at I wanted to keep the intercom in for dad!! Couldn’t believe for price they were not going to replace a new mechanism and a wasn’t going to be guaranteed the guarantee! Felt instead of saying he couldn’t do the job!! Decided on just having the door supposed to be resealed and supposed to have made in draft proof which it isn’t a neighbour actually pointed out to me that it had not been resealed unfortunately a was not on ball at the time as dad had been taking in to hospital totally took advantage of my vulnerability at time!!! And had check to ask for cash in hand!!! Shocking for such a rated company!!!

Getting windows fitted filled me and my wife with fear due to the size of the job . However from start to finish Millar windows and doors Ltd were excellent. They visited the house measured up and gave us a very reasonable quote very quickly. The Fit itself was done quickly and to a fantastic standard, the fitter Steven didn’t stop and completed the work in the time quoted . Couldn’t be happier with the finish and the service , would 100% recommend this company .

Amazing business. Do not hesitate to use this company. Very quick turnaround, great service. George explained products in a fifteen min survey and there was no hard sell. Even when a supplier let them down with our door delivery. Denise managed this brilliantly and got the door delivered as soon as possible … and then ensured it was fitted the same day. Quality of work fantastic. Our house is a lot warmer now we have replaced windows and the works will have a added great value to our home. Amazing. Thanks to all at Millar windows !!! Highly recommend them.

Absolutely fantastic company. From first contact and George coming out to measure and quote (great prices) thousands of££ cheaper than 3 other companies. The fitting team of Stevie and John are total gentlemen that have done a great job of first doing 6 windows and composite door then again on a composite side garage door and window. All rubbish taken away and full clean up after themselves Honestly 5 stars does not do justice to this company

Just had all of our windows a s doors replaced- what an outstanding job from start to finish! George and Denise were a dream to work with, and Stevie and John were outstanding fitters! The windows and doors are such high quality, the boys cleaned up everything and went above and beyond - nothing was a bother! Cannot recommend this company highly enough!

We recently hired Millar Windows and Doors to supply and install new PVC windows, a new patio door and also a new composite external door. From the very beginning, they were totally professional – no pushy sales at all. George understood what we wanted, measured quickly and then we were kept up to date with everything from the point of ordering to completion by Denise. Stevie and John (our fitters) were fantastic, so much so, we felt a bit sad when it was time for them to leave and it’s not often you say that about tradespeople! Great banter and top skills. Everything went like clockwork and they turned up when they said they would, did a brilliant job and were exceptionally careful and diligent about clearing up as they went. The products themselves are really great quality, suit the property so well and are exceptionally good value for money. We would have easily had to pay 2-3 times as much had we gone with one of the ‘big name’ companies. What swayed us even more was that there was no money to pay at all until the job was completed. All in all, we are delighted with the job and would not hesitate to recommend Millar Windows and Doors to anyone. Thank you!
