Planned maintenance and PPM services
Est. 1991.
Maintaining education, public sector, heritage and residential buildings through planned preventative and cyclical maintenance programmes.
Planned preventive maintenance programmes across education, public sector, heritage and residential buildings require a contractor with the right breadth of technical capability and a thorough understanding of the estates they are maintaining.
Sinden covers external fabric, roofing, windows and doors, decorations and specialist heritage fabric, working across occupied schools, NHS estates, residential and listed buildings.


A planned maintenance contractor that keeps your estate in the right condition, year after year.
Providing planned maintenance programmes across occupied education, residential, public sector and heritage estates.
External fabric, roofing, windows and doors
We cover the full scope of external planned maintenance works, with the technical depth and sequencing experience to deliver programmes efficiently across occupied and operational buildings.
Specialist maintenance for heritage and listed buildings
Our knowledge of historic fabric, appropriate materials and conservation techniques means planned maintenance on heritage assets is carried out to the standard these buildings warrant.
Programmed around your operational calendar
We plan every maintenance programme around the specific operational realities of the estate, whether that is a school term, an NHS rota or a residential occupancy schedule.
A trusted route for delivering Capital Works
The familiarity with a building and client relationship built during a maintenance programme means we are well placed to support clients when larger capital works arise.
