We used ERG to fit new windows and front door. All the workmen from salesperson to fitters were extremely polite, professional and very tidy, would highly recommend this company.

ERG fitted new half glazed back door and 2 new kitchen windows. Great job, completed in 1 day, Looks great, very tidy worker.

Had a follow up visit to adjust our bifold doors. Very happy with the job. Big compliment to the staff who came 40 miles to do the job. Quick, neat, tidy. Great ambassadors for the company.

We recently had a new patio door fitted by ERG Scotland, and we couldn’t be happier with the result. From start to finish, the service was professional and stress-free. A special mention to Keiran, our fitter, who did an outstanding job — he was punctual, polite, and his attention to detail was excellent. The finish is perfect, and everything was left clean and tidy. Highly recommend ERG for anyone looking for quality workmanship and great customer care.

I have used ERG twice recently for my properties and on both occasions the service they have given me has been first class. Their quotations have been very competitive, communications have been swift and efficient. And the work was completed on time with no fuss. The staff are very friendly and very knowledgeable and I won't hesitate to use them again.

From initial enquiry, right up to completion, we found the service first class. All employees were polite, helpful and totally professional. There was straight forward pricing with no pressure. The fitter arrived promptly and worked non stop throughout the 2 days it took to complete the work. Our property was left immaculately tidy both inside and out. Would highly recommend.

Everyone was so helpful and the process, from getting a quote to installation, was quick and simple. Good quality windows and doors and installation team were very respectful of our property. Highly recommend ERG.

Brilliant service from ERG Windows. My new patio doors look fantastic and the quality is excellent. Kieran, who did the installation, was professional, friendly, and left everything spotless. Highly recommend!

From start to finish the whole experience was easy to follow from the initial meeting with the salesman who didn't pressure sell,the very efficient survey and probably the best and hardest working window fitter I have seen(Neil).Even the billing was exact and very well explained.

Needed some work done that couldn't be completed until other work was done, and ERG hung with me while I was bounced around through that without a word of complaint, even though I know their scheduling got messed about as well. When they did show up, they immediately put on masks without a word of argument (more rare than should be the case, unfortunately) and did a superb job very efficiently. I did feel that each of their teams (sales, customer service and installers) were consistently courteous; I recommend ERG without hesitation.

Great company to deal with. Even when you know exactly what you want the surveyor will help with suggestions for improvements such as a wider door so our customers can fit through with their luggage etc. They finished the door off beautifully even adding a little extra trim on the inside that I requested to make the finish perfect. I would highly recommend this company and will definitely use again. The whole team are very helpful from salesmen, to fitters, surveyor and office staff...superb..thank you

We recently (April 2025) had a new front door and four windows installed in our house in Fortrose, Highland Region and are delighted with the high quality of the products and the skilled workmanship of the installers.
The composite door is of the high quality we were looking for since our house faces the sea (about 150 metres away) and the prevailing wind. Despite several days of severe gales and driving rain, it has already proved its worth - an enormous improvement on our previous door which although double glazed allowed the wind to penetrate round its edges.
The four PVC windows we had fitted on the north facing side of the house are also impressive. As well as having a high standard of insulation, they are also very attractive to look at, as has been commented on by several visitors.
The whole process from the first survey through to final installation was first class, especially the efficiency and friendliness of the staff from salesman, surveyor, receptionist and installers.
We should add, that we had a conservatory and garage conversion carried out by ERG Scotland about five years ago and were also very impressed by them.
