Renovated conservatory, and replaced all windows and doors. Great service from advice right through to fitting and follow up. Helpful suggestions about options available to us, also listened to what we wanted did not push own ideas like some other companies. Great people, easy to have around the house and did a great job. Work has been widely admired and we remain very happy with the results. Have recommended to others

Very pleased with the work and attention to detail provided by David and his team. Highly recommended.

I am so pleased with the renovation of the front of my house. David took the time to research my specific requests for non-typical garage doors, in-keeping with the style of my house, and give me options and advice. He rebuilt a front step and fence and added finishing touches I hadn’t thought of. The fitting of a new front door and the garage doors was efficient with an excellent finish. Any snagging issues have been dealt with promptly and I would definitely use the team again. My house is transformed!

We have just had a new conservatory installed by Northumbrian Windows. David was easy to deal with. He explained everything and was easy to contact. The workers were pleasant and professional; they got on with it. We are very pleased with the final result.

We had 12 windows and a backdoor fitted and was impressed from the start. From getting the initial quote for the work, where they were professional and gave really helpful advice, to the fitting where their workmanship is excellent – they hold themselves to really high standards. And they're a really nice bunch of blokes too. Couldn't recommend highly enough.

Had our new windows and doors fitted by Northumbrian Windows in May 22. What a fantastic service! Their products are top quality and the price compared to the name brands is excellent. As for the fitting service, it’s incredibly professional, but also very efficient, a great squad of lads. I can’t recommend Dave highly enough. If you’re based in Northumberland, there isn’t any point in considering anyone else.
