Built on Experience, Run with Care
Honest advice, clear communication, and reliable delivery.
Our Story
SERGYO CONSTRUCTIONS LTD was incorporated in 2017, bringing together skilled tradespeople with real construction experience going back to 2001.
Our team consists of NVQ-qualified professionals, meeting recognised industry standards for safety, workmanship, and technical competence. We believe work should be done properly, safely, and without cutting corners.
Based in East London, we have developed a deep understanding of the local architecture. Whether it is restoring a Victorian terrace in Walthamstow or adding a modern rear extension in Hackney, we know how to blend new structures seamlessly with existing character.
The business is run with a straightforward approach: honest advice, clear communication, and reliable delivery. From the first visit to the final handover, you know who you are dealing with and what to expect.
We know that building work can be stressful for homeowners. That is why we manage the entire process with military precision—keeping sites clean, neighbours happy, and communication lines open every step of the way.
Quality is not just a buzzword for us; it is the foundation of our reputation. We treat every project as if it were our own home, ensuring that materials are high-grade and finishes are precise. From the unseen structural supports to the final visible grout lines, everything is executed with care.
Ultimately, we aim to build relationships as strong as our masonry. Many of our clients come back to us for second or third projects, knowing they can rely on Sergyo Constructions to deliver on time, on budget, and to an exceptional standard.
We are proud to serve the diverse communities of East London, from the terraced streets of Walthamstow and Leyton to the conservation areas of Wanstead and Bow. We understand the specific planning constraints and structural challenges often found in these properties, ensuring a smooth path from concept to completion.
Whether you are looking to create more space for a growing family or simply want to restore the original beauty of your home, we are here to help to make it happen.
