Posted on Google Ross MurrayTrustindex verifies that the original source of the review is Google. I’m very pleased with the work carried out by RePlace Windows. Last July, Scott came out to discuss exactly what I was looking for. He was friendly, respectful, and came across as genuinely honest and professional. He took the time to explain my options, the benefits of choosing RePlace Windows, and provided a very competitive quote. The following week, a technician carried out the survey, which took around an hour and was handled efficiently with minimal disruption. In September, the fitters completed the installation over two days. Although I can’t remember their names, they worked extremely hard, even staying into the evening to make sure everything was finished to a good standard. The windows look great. About a week later, someone also returned to repair the plasterwork, which I really appreciated. Scott then followed up afterwards to make sure everything had gone well — a great level of customer service that really stood out. I would happily recommend RePlace Windows to anyone looking for a professional, reliable, and considerate company.Posted on Google Jo MurrayTrustindex verifies that the original source of the review is Google. Just to say we recently had all of our windows replaced by RePlace and had an amazing experience! From the initial home visit with Scott to post installation, everything was great. We had only couple of minor snags (to be expected when replacing 13 windows) and the post installation customer service was impeccable! Quality products, competitively priced, excellent installation and super customer service. Huge shout out to the whole RePlace Team, this company knows what they're doing and I would highly recommend them to anyone considering new windows😁 https://www.replacewindowslimited.co.ukPosted on Google Carol MacKinnonTrustindex verifies that the original source of the review is Google.

I dont know how my name came up in the reviews of this company. I dont need windows or doors,Posted on Google Adam MackinnonTrustindex verifies that the original source of the review is Google. Kai and the team were great throughout the process. Windows installed are top qualityPosted on Google Kathleen DoyleTrustindex verifies that the original source of the review is Google. I had my windows replaced last week and the whole experience was excellent from start to finish. I highly recommend! Scott, the salesperson, was brilliant. He was friendly, straightforward, and there was absolutely no hard sell. After previous experiences of salespeople sitting in my house for two hours trying to wear me down, this was a breath of fresh air. The product genuinely sold itself, and Scott was in and out quickly, which I really appreciated. Communication throughout the process was consistently excellent. I was kept updated at every stage and always knew what was happening next. The fitters were great too — efficient, tidy, punctual, and really easy to feel at ease with in the house. They worked smoothly, respected the space, and left everything spotless. Overall, a genuinely positive experience and a company I’d highly recommend.
