I am an experienced builder providing a wide range of interior and exterior construction services. I specialise in all aspects of building work, including bricklaying, plastering, painting and decorating, paving, flooring, plumbing, and fencing. I also carry out complete projects such as driveways, kitchens, bathrooms, garage builds, extensions, and loft conversions. From small repairs to full renovations, I handle every job with care and attention to detail. I take pride in delivering high-quality, strong, and reliable work, ensuring every project is completed to a professional standard. I focus on good workmanship, safety, and customer satisfaction at all times. I am hardworking, trustworthy, and able to work independently or as part of a team. No job is too big or small, and I always aim to finish on time and within budget.

Coopers provided an excellent service. Jack came and reviewed the problem, showing me photos of the leak and damage, and gave various options and prices of what I could do. In the end, I decided on a full roof replacement along with guttering and soffits. I got them to fit a Velux window and sun tunnel too. The project management was excellent. Scaffolding came within a day and work started following Monday. The job was completed in four days to a professional standard. Highly recommended.

My names Tom, I have been in the real estate sector for over 10 years and have done everything from general property maintenance, new bathrooms, painting/decorating, demolition contracts and most recently constructed 9 ultra high spec homes. High quality and impeccable workmanship are key values to me and ensuring the client is satisfied and more, with the work they are receiving. I am very well connected with all trades and can provide a top tier service for all types of project management no matter how big or small the job may be. I am also extremely capable at doing many manual labour jobs, but often favour a shorter timeline for my clients project completion and therefore prefer to draft in experienced trades to get the job completed. Above all I am very friendly, well spoken and always keen to deliver what is asked of me.
