    "I recently had extensive work completed to my property, including guttering, drainage, and rendering. I couldn't be more pleased with the results. Syze demonstrated exceptional professionalism and craftsmanship. The quality of the work is outstanding—everything was completed to a very high standard with real care and precision. What truly stood out was the attention to detail. Every aspect of the job was meticulously planned and executed, ensuring not only a flawless finish but also long-term durability. It’s clear that the team took great pride in their work, going above and beyond to make sure every element was robust, weatherproof, and built to last for many years to come. The site was always kept tidy, and communication throughout was excellent. I was kept informed at every stage, which made the whole process smooth and stress-free. I highly recommended Simon's team for anyone looking for reliable and quality focused building work. Thank you again for a fantastic job! Pete"

    Roma - Image 1 2 images Roma - Image 2 "Converted my old tired hot leaking conservatory into a lovely warm luxurious extension to my living room. Extremely pleased with their quality of work and always willing to work with me to give me what I want even when I changed my mind a few times! Clean and tidy too."

    Trader reply: "Thank you for your positive feedback and encouraging comments! - your request to install full width bifolds as you saw the build taking shape was a great call in our opinion."
