Customer Reviews
Local Customer Reviews From Carmarthenshire & Swansea
Posted on Diane BevanTrustindex verifies that the original source of the review is Google. I was really impressed by the quality of the French doors, but more impressed by the workmanship John took time to discover how poorly the previous doors had been fitted and made sure that this installation would last, previous doors seemed to be held in by fresh air! I will be having them back for windows in the New Year This is diagonally something where you do actually get what you pay for in quality and experiencePosted on Abhishek RavikumarTrustindex verifies that the original source of the review is Google. Had my front porch, French doors, and front door fitted by John and his boys (Adam and Ash). They’re a true family business and an absolute breeze to work with. Nothing was rushed, they paid attention to every little detail, and the quality of their work really shows. I couldn’t be happier with the result. I really wish them all the best and will definitely be going back to them for any future work.Posted on Jonathan ThomasTrustindex verifies that the original source of the review is Google. From start to finish, Adam and the team were absolutely fabulous. The experience of his fitter was invaluable. Absolutely made up with the job they have done, would defiantly recommend them to anybody!Posted on graham shimminTrustindex verifies that the original source of the review is Google. We needed three replacement windows, which was obviously too small a job for some of the local window companies to bother responding. Fortunately Lion Guard came to our rescue and we are very pleased with the result. They are a relatively new family business but are very professional in their approach and are deserving of our support. We highly recommend them and will certainly be giving them our future business.Posted on Chris JonesTrustindex verifies that the original source of the review is Google. Excellent service from first visit to the completion of the job. Kept fully informed at all stages. Highly recommended!Posted on Adam BowdenTrustindex verifies that the original source of the review is Google. The whole process from valuation to completion was effortless.This company (family) strive to give the customer, high quality products at good prices. I have never seen a window look so good. Me and my dog are over the moon (paw) with it.Posted on Rachel BuckleyTrustindex verifies that the original source of the review is Google. The whole team at Lion Guard were great! The fitting was to an excellent standard, they were efficient and communication was exceptional! They are a new company and we will definitely use them again in the future! The whole team/ family were lovely to deal with!
