After receiving multiple quotes from companies, we went with Caledonia for a new front door. From the beginning, the team including Robert were knowledgeable and friendly without being pushy for sales. We decided to go with the less popular colour 'Irish Oak' - we actually dropped by their building in Castlecary to see the colour in real life (we wanted to ensure it would fit the colour of our house), and they brought us out an offcut to take home so we could see it situ, which was so kind and helpful. The whole process from ordering to fitting took just over 5 weeks; Ellis who completed the door frame fitting was absolutely brilliant. The new door has made such a massive difference, and we will be back in touch next year to order our new back door from them.

⭐⭐⭐⭐⭐ Outstanding Service from Start to Finish! After an absolutely horrendous experience with Clydebuilt Windows and Doors, who installed a patio door that was poorly fitted, left us with ongoing problems and then went into liquidation, leaving us to deal with the consequences, I was understandably apprehensive about trusting another company. Thankfully, Caledonia Windows and Doors completely restored my faith that there are still companies out there who genuinely care about their customers and take real pride in their work. From my initial conversations with Leander, who took the time to listen to our requirements and understand the situation we’d been left in, to Stephen, who handled the measuring and sales process, the entire experience was seamless. What I particularly appreciated was their understanding of the financial position we’d been left in through no fault of our own. They were incredibly accommodating and worked with us on the price of a replacement door, which was a genuinely kind gesture and something they certainly weren’t obliged to do. Then came the installation by Chick, and what a difference! The workmanship was absolutely first class. The attention to detail, quality of fitting and overall finish were outstanding. It was immediately obvious that this was someone who genuinely takes pride in doing a job properly. What really sets Caledonia apart, though, is the people. Every single person we dealt with was friendly, approachable, professional and genuinely committed to providing excellent customer service. No chasing, no excuses, no unnecessary hassle. Just a company that does exactly what it promises and does it exceptionally well. After everything we’d been through with Clydebuilt, the contrast couldn’t have been greater. A massive thank you to Leander, Stephen and Chick. You’ve turned what had been an incredibly stressful and disappointing experience into a really positive one. I genuinely cannot recommend Caledonia Windows and Doors highly enough. If you’re looking for quality workmanship, excellent customer service and a company you can trust, look no further. An absolutely deserved five stars! ⭐⭐⭐⭐⭐

Excellent company to deal with - great friendly communication during the initial visit with Graham, with Gillian in the office and Ellis during door fitting. Our new front door is amazing. Thanks again!

A really great experience from beginning to end from Graham coming out to measure no ridiculous 3 hour sales pitch he knew what we wanted as soon as we told him and he had a quote over to us the next day . The fitting team were superb respectful hard working and the communication was great at all stages . The quality of the doors and windows is first class I would highly recommend Caledonia to anyone who is looking for new windows and doors

A great experience dealing with Caledonia windows & doors. From initial phone call, to Graham visiting to take measurements right up to the 2 lads fitting the doors everyone was great to deal with while being very professional. The whole process went very smoothly. I was especially impressed with the customer service team - Gillian in particular could not have being anymore helpful! We are so pleased with our doors and would highly recommend this company! Thanks again, Ciara Flynn

A great service from start to finish, 4 windows and a tricky cat flap in the conservatory - everything went exactly as planned and Robert and the team were so friendly and helpful - always on time, tidied everything as they went along and made us feel very confident in the work they were doing. Delighted with the end result and would recommend to everyone!

I am so happy with my new front door. The staff were excellent. Ellis who fitted my door was so happy and cheerful and so professional. If I was thinking of new windows etc I wouldn't go anywhere else. Dont think they would be beaten on price or workmanship.
