 Trustindex verifies that the original source of the review is Google. This firm was able to fix my roof when previous companies had taken the money but not fixed the leak. They also did a great job of fixing the damaged plaster and ceiling in the room below. I’m very grateful to them and wouldn’t hesitate to use them again.

 Trustindex verifies that the original source of the review is Google. I couldn’t be happier with the bathroom renovation Harry completed for me. From start to finish, he was professional, reliable, and incredibly skilled. The work was done to a very high standard, with great attention to detail, and completed right on schedule — which is rare and so appreciated! Harry communicated clearly throughout the project, always made sure I was happy with each stage, and kept the space tidy at the end of each day. The finished bathroom looks amazing and has exceeded my expectations. I’d highly recommend Harry to anyone looking for quality craftsmanship and a stress-free renovation experience.

 Trustindex verifies that the original source of the review is Google. First class re-model completed by Mark and Harry to open plan living with a new kitchen installation. They kept us informed throughout the whole build, helped us with advice when making decisions and were respectful to us and our home. Have already recommended them to others and would definitely use again.

 Trustindex verifies that the original source of the review is Google. This is a family business which I’ve used many times over the last 20 years or so in north London for various different types of building work, and exterior and interior decorating. They are reliable and helpful, their work is high quality and their prices are fair.
