The service was great from start to finish. Our project got delayed due to lockdown and I changed the specification changed multiple times but despite this the level of service never waivered right through to the tidying up carried out by the window fitter. Great service, great value, great selection of quality products - would highly recommend.

Thames Windows & Doors installed new uPVC windows and French doors for me and I was really impressed throughout the process. The initial consultation was extremely helpful, advising on the various options available to me and being extremely knowledgeable and patient with my questions. The survey and ordering stage was quick and efficient, and they made the process very efficient by liaising with my builders to ensure all was prepared for seamless installation and quality finish. They have provided excellent, timely, customer service throughout and everyone I have interacted with has been helpful
