Practical completion marks the point where a contractor formally hands a new development over to the client, but the building rarely reaches that milestone genuinely ready for occupation. Construction dust, protective film, adhesive residue, and general site debris remain across most surfaces, while snagging periods that follow practical completion bring contractors back on site to address defects even as cleaning and handover activity continues around them. Sentrex delivers construction and post build cleaning addressing new commercial and multi use developments from practical completion through to final occupation.



































Practical completion is a contractual milestone rather than a guarantee that a building is genuinely clean and ready for use. Contractors typically remove major waste and equipment before this point, but fine construction dust, protective film covering flooring and fittings, and adhesive residue from installation work remain across most surfaces.
New developments often complete in phases, with some floors or units reaching practical completion while work continues elsewhere on the same site. This staggered handover means cleaning needs to work around ongoing construction activity rather than waiting for the entire development to finish at once.
Multi unit developments, from office buildings to mixed use schemes, add further complexity, since each unit or floor may reach completion on a different timescale depending on fit out progress and individual tenant requirements.
Snagging periods bring contractors back to address defects identified after practical completion, from minor decoration touch ups to more substantial remedial work. This ongoing activity generates further dust and debris even as areas of the building may already be cleaned and ready for occupation.
A cleaning programme that spans the full snagging period, rather than a single clean at practical completion, protects the standard already achieved in completed areas while accommodating the reality that snagging work continues in parallel. Without this ongoing attention, a development can look genuinely finished one week and visibly compromised the next as snagging works progress.
Coordinating cleaning around the snagging schedule, rather than treating it as a fixed one off event, delivers a development that stays presentable throughout the transition from construction site to occupied building.
Industrial deep cleaning addresses the thorough, ground up clean a new development requires before occupation, reaching areas standard cleaning routines are not designed to cover. Floor cleaning removes protective film, adhesive residue, and construction dust from newly laid flooring across every unit and common area.
Builders waste removal clears packaging, offcuts, and general construction debris left behind once the main works conclude, while site waste removal addresses external areas, car parks, and landscaped grounds where construction debris often accumulates well after internal areas are complete.
Clinical waste management addresses the specific waste streams care homes generate, including continence products and other clinical waste requiring careful, compliant handling and disposal separate from general waste.
New developments increasingly include taller buildings, from residential towers to multi storey commercial schemes, each requiring exterior cleaning methods suited to height. Commercial window cleaning removes construction dust and haze from glazing throughout the development, restoring the clarity a finished building needs to present well at handover.
Abseil access reaches upper floors on taller developments where building design makes other methods impractical, while cradle access suits buildings with integrated cradle systems installed during construction specifically to support ongoing maintenance and cleaning once occupied.
New developments rarely sell or let every unit before or immediately at practical completion, leaving some units standing empty for weeks or months after the rest of the building is occupied. Our void property cleaning service keeps these unsold or unlet units presentable, supporting viewings and marketing activity while avoiding the dust and neglect that empty units can otherwise accumulate.
Maintaining void units to a consistent standard protects the development’s overall presentation, since a scruffy, visibly empty unit undermines confidence for prospective buyers or tenants considering the building as a whole.
Once a development moves from construction into occupied use, cleaning needs to transition alongside wider building maintenance. Our handyman services address the minor snagging and adjustment work that continues to surface in the weeks following occupation, while our property maintenance service supports building fabric and mechanical systems as the development settles into regular use.
Planning this transition in advance, rather than treating handover cleaning and ongoing maintenance as separate procurement decisions, gives developers and managing agents a single point of contact covering the full lifecycle from practical completion through to established occupation.

Our accreditations including CHAS, Safe Contractor, ISO 9001, and ISO 14001 demonstrate systematic approaches satisfying the procurement requirements developers, contractors, and managing agents expect. Our approach emphasises coordinating cleaning around live construction and snagging activity, working alongside contractors rather than waiting until every trade has left site.
Developers, contractors, and managing agents handling new developments can contact us on 0333 240 1145 to discuss cleaning addressing practical completion, ongoing snagging periods, void unit presentation, and the transition into established building maintenance.
