What our clients say about us

Ryan T
We've used Caledonian Windows for a number of years and have had two Rockdoors installed and eaves protectors fitted previously. Each time the service has been first class and a fair price asked. Our most recent experience was really positive with Gary in sales and Richard who installed our door - couldn't have asked for better. Great to support a local company too. When it's time to replace our windows - Caledonian will be our first port of call.
Natalie Curtis
Great service start to finish , lovely door ,
Excellent product, installation and support. Only small niggle was lack of updates re installation date and warranty certificate but once contacted responses were quick. I understand there was a covid outbreak at the factory so understandably this would have pushed installation date out. Overall extremely happy and highly recommend!
Gillian Berretti - McMurtrie
Service was excellent from the start. No pushing to do more than we wanted. They surveyed and did the job on time and the workmen cleaned up after. The windows are great and I would go back and recommend the company.
Alan Breckenridge
The team at Caledonian were first class from start to finish! Jason was excellent to deal with and if anything was needed then it was dealt with. Competitive price and an excellent product in our front door! Would highly recommend and will use again!
John Murray
5 star service from the measuring to the installation. I will definitely use these guys again and highly recommend anyone to do the same!
Maureen Mclean
Absolutely beautiful windows fitted. So proud of them. The quality and service is of the highest standard and we cannot praise them enough. Right from the beginning to the end, we were always kept well informed with progress. All the team, from measuring up to the finishing touches was very professional. We will definitely use them for our future projects. Many thanks again
Craig MacDonald
Fantastic experience with Caledonian Windows from start to finish!! The price for the job was extremely competitive and I truly believe their windows to be a superior product to the rest of competition in the area. All windows were installed on time and with care by excellent fitters. They did an immaculate job and cleared everything up as they went along. Cant recommend Caledonian Windows enough!!!!! :)

Had a replacement window fitted this morning. Guys came when they said they would, took out the cracked window and replaced it with the new. Fantastic service, fast professional couldn’t fault it.
