We have a terraced Victorian house with a very old front bay window - wind whistled through it whoever was unlucky enough to sit on the sofa with their back to the window ended up with a very cold neck. Phil came round, measured up and explained what we would need to do to rectify the problem. We had been previously quoted by another company to completely replace the whole window. This would have been unnecessary and very expensive. A price was agreed the job scheduled pretty quickly and took only half a day to do replacing the bottom sash and repair the workings of the window.

Phil was very professional and friendly and we are extremely pleased with the final result as the window fits and slides perfectly, look fantastic and the room is noticeably warmer. I would definitely recommend anyone to give Novells a call.

“Our Victorian terrace house has needed some of the windows refurbished or renewed for some time. I contacted Novells to carry out a site visit and provide an assessment and estimate for the work. Phil was very quick in responding and arranged a suitable date for the site visit. I found Phil to be very upfront and honest about the work which needed to be done and he was able to assure me that the remaining windows were in good repair and only needed decorating. The team installed 4 new box sash windows and refurbished the window boxes. The new windows were very well matched to the Victoria originals. The quality of the work was excellent and equally important the team kept any dust generated to a minimum and tidied up at the end of each day, which was much appreciated. The entire team was very professional, friendly and punctual throughout the project. I would have no hesitation to engage the team and Novells again and I have already recommended them to neighbours, friends and family. Thanks again for a great job.”
