We were replacing our conservatory windows, doors & roof. Scott visited us initially to find out what we required to be done. After placing our order James came out to confirm measurements with Jim who would be one of the team doing the work. On the 1st day of work Jim & Tony arrived early & barely stopped for a break all day. They were both good workers, keeping us informed at every stage of the work. Highly delighted with the quality of workmanship & would not hesitate to recommend Northern Lights Home Improvements to anyone requiring any work to be carried out by them.

We had new door and windows fitted this week. What an excellent job. The fitters were very professional, polite and cheery. They cleaned up everything and took away old windows.

Highly recommended.

We recently had our Fascias, Soffits & Guttering replaced by Northern Lights and couldn't be happier with the result! Jim was the fitter and was careful to ensure I knew what was happening throughout the work. His friendly & professional manner was only bettered by the quality of his work! Jim always gave that little bit more to ensure the work was 100% and that I was completely happy. Northern Lights may not be the cheapest option, but in my opinion must be the best!

I can't recommend highly enough.
Brian Webb

I would like to commend your installers, Jim and Nick, for the excellent work they did and the complete clear up of the site and removal of the old door and debris from the installation.

I was very impressed with not just the quality of work carried out for all the Roofline and new Doors installed but also as we were kept updated throughout the installation process. I saw several examples where your staff went over and above what i expected. Ten out of ten for attention to detail from start to finish.

I would recommend Northern Lights to anyone thinking of using this company.

I'm very impressed with the "finished" look and with the whole job I'm also most impressed with the "lads" for their "old school" attitude and attention to detail - also for explaining things as they went along. It was a pleasure to meet them and to find people who still take great pride in their work!

I will certainly be recommending you and your "lads" to my friends!

Thank you!!

Having previously wasted good money on a botched felt flat roof replacement several years ago I decided to have it replaced by Northern Lights Home improvements. The result is like chalk and cheese not only does the new EDPM look good, but it was also done professionally by a team who know what they are doing. The new roof looks stunning in comparison to the old one. I can recommend them for their service and professional attitude.
Robert L Watson

I'm very impressed with the products Northern Lights Home Improvements provide and the quality of service and installation skills of the tradesmen. I recently had two replacement double glazed windows installed along with an electrically powered garage door. I'm delighted with my windows and garage door and have no hesitation in recommending Northern Lights Home Improvements to anybody who is looking to upgrade their windows, doors or other relevant parts of their home. It's good to be able to rely on a company which is local to this area.

I have nothing but praise for James and his team. From Phil coming and advising on my options for my front door and French doors to the two fitters who carried out the work in double quick time. I was impressed with the excellent service provided. I will definitely use them again and wouldn't hesitate in recommending them.

Good job guys and thank you!
Mr Schenk, Denview Crescent
