I'm a property developer and was looking for a reputable sash window company to refurbish the windows of my current project. I found Novells online and they carried out a site survey within 48hr and fitted my project into their schedule for a couple of days later. They were professional, fast, courteous, cleaned up after themselves and did a great job. I'll 100% will be using them again on future jobs. The photo doesn't give it justice but a brilliant job was done.I can highly recommend them.
Really professional and punctual company. I’m really happy with my new timber sash bay window which Novell’s repaired/replaced. It’s very high quality work and looks fantastic. When I had an unrelated issue with the sash pulley system, Phil came out to check it on the same day free of charge - very prompt and helpful! Nicki is great to deal with over email and sorts all of the appointments and payments quickly, with a very friendly manner. Highly recommend this company!
Super happy with my windows and French door from Novells. You get what you pay for which is a quality product fitted quickly and professionally by the team and ably supported by Nikki from the office. The guys who came were great to have in the house, worked the whole time they were there and left the site cleaner than it was when they arrived!
Excellent service provided by Novells. From my initial consultation with Phil, regular updates from Nicki, the installation of the sashes by Piotr, Sharas and Yakob, them clearing up and leaving my place spotless and, to the aftercare provided by Nicki and Piotr. Nicki is so helpful and quick to respond. Piotr was so helpful in dealing promptly with the aftercare. Everyone is friendly and professional. I will definitely use Novells again and would recommend them to others. Phil, you have an amazing team. 👍🏾
