We had 5 new windows fitted today and are really happy with the work carried out. Liam was great to deal with right from getting the initial quote through to the job being completed. Both Liam and Brad worked non stop and everything was finished to a really high standard. I would have no hesitation in recommending this company to anyone.
Very approachable, quick to respond to queries and work completed very promptly. Would highly recommend.
Liam did a brilliant job. He was the first to contact us and was around the next day. We ordered a replacement bifold door for a sliding door. His work is first class with reasonable costs. Would recommend him to anyone and will keep him in mind for future work. Thank you Liam 😊
Really good workmanship. Did a great job; very happy with the work. Will be using his services again. Thank you.
Liam from North West Windows and Doors was brilliant. He came very promptly to view my badly fitted new door by another company, then arranged a prompt date to re-fit the door so it closed easily. The end result was a fantastic job at a very reasonable cost. The door now closes and locks easily as it should. Thankyou very much Liam i would most definately recomend you to any potential customer and your details are now firmly in my contractor address book. 👍👍

More than pleased with our new window and the whole process. Was efficient and professional and very polite. Was very informative and helpful - Highly recommended.
Liam came to replace a hinge on the front door that had broken. Gave me a quote beforehand. Very happy with the repair. The door opens and closes much more smoothly than when it was first fitted.
Liam paid a great deal of attention to detail in finishing the trim, both inside and out, and took pains to get things just right where it was not straightforward. He was pleasant to have in the house, reliable and we are pleased with the quality of the windows he fitted.
Repair needed Liam came same day and could not have been more helpful and friendly. Great work without any fuss and and cheaper than expected
Arrived on time when he said he would, prompt with the free quote, didn't try to rip me off (told me when something could just be fixed and not replaced). Happy with the final outcome of two well fitted new windows and my locks for both doors sorted after moving in a few months ago. Will use again in the future.
Friendly, professional, hard working and tidy worker. Trustworthy man we have already recommended to friends and neighbours. We chose this worker after being recommended by a neighbour and seeing the work he’s done for ourselves.
Just had 6 windows and 2 doors replaced by Liam. Got a good impression right from initial meeting when the quote was done. Liam has such a nice manner; polite, friendly and approachable. Had a slight issue with the finish as I didn't want the wide plastic strips around the doors and windows but my concerns were listened to calmly, and dealt with professionally, until we agreed a solution. Really please with the end result and would have no hesitation in recommending Liam and his team - Thank you
Liam was fantastic from start to finish. Providing the quote to installation a couple of weeks later. I am so happy with the work that I would not hesitate to use again and would recommend to anyone Thanks again Liam
I contacted Northwest double glazing within a very good response of time they came straight out with no messing one of the guys he took all the measurements he went away and it was a very quick turnaround. They came back with a price. I was very satisfied. I’m very compatible really outstanding workmanship very polite. A really credit to Liam and the team would highly recommend them and I am waiting for another project for them to come back on five stars company a big massive thank you to Northwest double
Liam has been professional and helpful from the very start. He knows his stuff and was able to point us in the right direction to choose the front door we wanted. He stuck to his promised timescales and was thorough with every element of the work. We are delighted and will definitely use North West Double Glazing for further work. Thank you!
