The windows and Bifold doors are very high quality and installed to a very high standard. Thank youPosted on Mohamed SiddeeqTrustindex verifies that the original source of the review is Google. Having already got quotes from the big well known window companies, I wanted to check local suppliers and I found Durajoin on a google search. They offered aluminium for not much more than the upvc quotes of the other suppliers. Not knowing the company, Piyush offered to show me around his factory and see his operation which together with his personal attention to detail and willingness to discuss the best options gave me confidence to go ahead and order new aluminium bifold doors and windows for my flat in Earls Court. There were a few challenges with the access and location to my flat so a good solution and design was devised by Piyush and Im very happy with the end result. I should add that there were a few minor issues that arose after installation and Piyush was quick to get his people out to sort them out. Therefore I have no hesitation to recommend this company.Posted on Fawad RazaqzadaTrustindex verifies that the original source of the review is Google. Massive sliding windows by Durajion. They all glide very smoothly to either the left or right, giving massive access to the garden. Very good quality. They don’t let heat scape easily either. Highly recommended!Posted on Alia QureshiTrustindex verifies that the original source of the review is Google. From start to finish what a lovely and professional service! The knowledge from Avi of every angle, every window style, every vision we had made us so comfortable to put all our trust into Durajoin! My windows are exactly how I envisioned them. They complete the whole look of the house and I couldnt be happier. Highly recommended and will be definitely using you again for future products!Posted on Amrutha NukalaTrustindex verifies that the original source of the review is Google. Piyush is absolutely worth recomending. Great eye for detail, brillaint workman ship and honest business person. Would not hesistate in recommending him to anyone
