From the initial contact there was no pressure. We never felt pressurised and had plenty of time to consider if we wanted to proceed. When we decided that we were going to accept the quote, we were given a complete breakdown of the various ways we could consider for payment. When the team arrived to complete the job they arrived on time, were polite and tidy workmen. The whole job was completed on time and there was no mess left behind for us to clear away. We were aware that there are cheaper companies around, however SRJ have a good reputation and a first class 10 year warranty on their kit. Both my wife and I are well pleased with the new windows and the follow up service given.

I had SRJ windows put into my home 22 years ago, Woodmill crescent Dunfermline. They took out two windows and replaced them with a big bay window, then did all the house and doors. Not one piece of rubbish did I pick up or clean up, they were amazing. So a few months ago, we needed a new door in our new house. Straight back to SRJ, never even thought of going anywhere else. Again they left the house and garden spotless. Workmen were brilliant not just with us but the were good with our neighbours also. My new door... absolutely beautiful, strong and sturdy. And no draughts. I will have no hesitation in using SRJ again and again. I am always recommending them too. Brilliant. Thank you.

This is our second time using SRJ for our windows as we moved home. We were in no doubt as to who we would use for our new home. The service was excellent and everything was installed efficiently and looks brilliant. We are about to use them again to fit new French doors wouldn’t consider anyone else now the quality and service is unbeatable

The staff have been great, from the salesman to the fitters to the after sales care it really does feel value for money. The windows and doors look great and have made a huge difference in our house. We needed a little bit of plastering afterwards which was followed up quickly and when was convenient for us.
