More About
Mark Stewart Tree Surgeon
Founded and led by Mark Stewart, a fully qualified arborist with NPTC certifications and extensive experience in both domestic and commercial tree work, the business has grown through word-of-mouth and a strong reputation for reliability. Mark also contract climbs for other tree surgery firms, bringing his technical expertise and high standards to projects of all sizes. Based in Denwick, we’re proud to serve our local community while also supporting clients throughout Northumberland and the wider North East.
At the heart of everything we do is a commitment to safety, professionalism, and customer satisfaction. We believe that every job — whether it’s a small pruning task or a large-scale dismantling — deserves the same level of care, precision, and respect for the environment. That’s why we work to British Standards, maintain £5 million in public liability insurance, and leave every site clean, tidy, and safe. We don’t just work on trees — we build long-standing relationships with clients who trust us to do the job right.
