After a lot of research I decided to use Ultimate to replace the windows and doors in my house. I am delighted with the service received! From start to finish everything was fantastic. The best bit was that there was no hard sell and no pressure to buy. The service was excellent from the initial contact right through to the end of the job! The lads who fitted the windows were great - on time, cleaned up and were friendly and respectful. If you're looking for windows and doors I cannot recommend Ultimate enough! Thanks for a great service
