Do You Offer Post-Construction Cleaning Services?
A finished build never looks finished. The joiners have packed up, the electrician has signed off the last socket, and the client walks in to find plaster dust on every ledge, silicone smears down the glass, and a fine grey film that has settled into places nobody thought to look. We get the call at exactly this point, usually a few days before handover, when the pressure is on and the site needs to go from a working environment to a presentable, occupiable space. Post-construction cleaning is the job that turns a technically complete building into one you can actually hand over the keys to.
We have cleaned everything from a single refurbished shop unit on Gloucester's Northgate Street to a 40,000 sq ft distribution shed near the M5. The scale changes, the principles do not. Below is how we approach it, what we look for, and why builders across Gloucestershire keep the number of a specialist cleaning crew in their phone rather than asking the labourers to "give it a once-over" at the end.
Why construction dust is a problem of its own
Ordinary office dust is mostly skin cells, fabric fibres and pollen. Construction dust is a different animal. It is a mix of gypsum from plasterboard, silica from cut brick and concrete, sawdust, MDF particles and set cement. It is heavier, more abrasive, and it travels. Cut one length of skirting with a mitre saw in a ground-floor room and you will find that dust on the second-floor window sills the next morning. It works its way into trickle vents, behind radiators, into the tracks of sliding doors and into the ridges of every extractor grille.
That is why you cannot dry-brush your way out of a post-construction clean. Sweeping just launches the fine particles back into the air, where they settle again over the following forty-eight hours. You end up cleaning the same surface three times and the client still runs a finger along the top of a door frame and comes away grey. We work wet where we can, and we use commercial vacuums fitted with genuine HEPA filtration so the fine silica is captured rather than redistributed. The difference between a builder's clean and a proper handover clean usually comes down to whether the dust was actually removed from the building or just moved around inside it.
The three-stage method we actually use on site
People talk about "the three phases" of construction cleaning as though it is a marketing slogan. It is not. It is a sequence dictated by how dirt behaves, and skipping a stage always costs you time later.
Stage one is the rough clear-down. Before anyone touches a surface with a cloth, the space needs to be emptied of the big stuff: offcuts, empty sealant tubes, packaging, protective floor sheeting, masking tape, stray fixings. We strip the temporary protection off floors and fittings, bag the waste, and get it into the skip. This is also when we tackle the heavy debris a broom can handle. There is no sense detailing a window sill when there is still a pile of plasterboard scraps in the corner throwing dust every time someone walks past.
Stage two is the detail clean. This is the labour-heavy heart of the job. Every surface gets worked from the top down: light fittings, ceiling vents, ductwork, the tops of door frames and cupboards, then walls, switch plates, skirting, and finally the floor. We wipe down the insides of newly fitted cupboards and wardrobes, because dust settles inside them just as readily as on top. Radiators get done front and back. Trickle vents and extract grilles get removed, cleaned and refitted. It is slow, methodical work and it is where experience shows, because it is easy to miss the underside of a handrail or the return edge of a reveal.
Stage three is the final polish, or "sparkle" clean. This happens as close to handover as the programme allows, ideally after all other trades are genuinely off site. Glass is brought to a streak-free finish, stainless steel is buffed, floors are given their final mop or burnish, and the whole space is checked with fresh eyes. If a plumber comes back in on the morning of handover to adjust a valve, stage three gets partly redone, and any decent client understands why. For larger jobs a full post-construction sequence sits comfortably within our wider deep cleaning services, which use the same top-down discipline.
The details that separate a handover clean from a hoover-round
A snag list from a facilities manager will almost always include the same handful of items, and they are the ones a rushed clean misses. We build our checks around them.
- Paint and plaster spots on glass. Overspray and splashes on windows and glazed partitions have to come off with a blade held at a low angle, wet, so the glass is not scratched. Done dry or with a worn blade, you swap one defect for another.
- Silicone and sealant smears. Fresh mastic wiped by a gloved thumb leaves a haze that ordinary glass cleaner will not shift. It needs the right solvent and a bit of patience.
- Adhesive labels and protective film. New windows, radiators, sanitaryware, glazed doors and white goods arrive plastered in barcode stickers and blue peel film. Left in the sun for a few weeks the adhesive bakes on. Removing it cleanly, without leaving gummy residue or gouging the surface, is a job in itself.
- Grout haze and cement film on new tiling. A cloudy film sits on freshly grouted tiles and stone. It needs a proprietary grout-haze remover and thorough rinsing, not a scrub with whatever is under the sink.
- Plaster splashes on ironmongery and sockets. Handles, hinges, sockets and switch plates collect flecks of plaster and paint that have to be picked off by hand.
- Dust inside light fittings and diffusers. Recessed downlights and diffuser panels trap a surprising amount of dust that is only visible once the lights are on.
None of these are dramatic. Together they are the difference between a space that reads as "finished" and one that reads as "nearly there". The client notices the nearly.
Health, safety and the paperwork that comes with a live site
A post-construction clean is not carried out in a tidy, empty building. More often than not there are still trades finishing off, materials being moved, and the ordinary hazards of a construction environment. That changes how we work compared with a routine office visit.
Silica dust is the headline risk. Prolonged exposure to respirable crystalline silica is a genuine occupational health issue, which is why we use HEPA-filtered extraction and, where dust levels warrant it, appropriate respiratory protection rather than treating it as ordinary housework. Our crews carry the relevant PPE as standard: hard hats and hi-vis when the site rules call for it, cut-resistant gloves for handling offcuts and glass, and safety footwear on every job. We work to a method statement and risk assessment for the specific site, we sign in and out like every other contractor, and we keep to the site's traffic and welfare arrangements. If your principal contractor needs our RAMS and insurance details before we set foot on site, that is normal and we have them ready. This overlap with heavier environments is exactly why our industrial cleaning and builders clean teams share training and kit.
Getting the timing and access right
The single biggest thing that derails a handover clean is sequencing. If the clean is booked before the last of the wet trades or the second-fix carpentry is genuinely done, you clean a surface that gets dirtied again within the day. We would always rather have an honest conversation about the programme than turn up to a room that is not ready.
Access is the other one. We are used to working evenings, weekends and nights so that a clean can happen in the gap between trades finishing and the client arriving. For an occupied refurbishment, where one floor is being handed over while the floor above is still a building site, we work around live areas and keep dust barriers intact. For a phased commercial fit-out we will clean floor by floor as each is signed off. This flexibility is why a lot of our post-construction work grows into ongoing commercial cleaning contracts once the client is in and settled, and why builders who hand over a spotless building tend to call us back for the next project.
Pricing follows the same logic as any specialist clean: it depends on the floor area, the state the site is left in, the finishes involved (a lot of glass and stone takes longer than a warehouse slab), and how tight the handover window is. We do not quote a per-square-foot rate over the phone and hope, because a clean site and a chaotic one are two completely different jobs. We come and look first.
How to brief a post-construction clean well
If you want an accurate quote and a smooth job, a few things help enormously. Tell us the gross internal area and the number of floors. Let us know what state the building will be in when we arrive, whether the skip is still on site, and whether floor protection is coming up or staying down. Flag any delicate finishes, natural stone, engineered timber, powder-coated metalwork, that need specific products. And give us the real handover date, not the optimistic one, so we can slot the final sparkle clean in at the right moment.
The more accurately you brief it, the closer our quote lands to the final invoice, and the fewer surprises anyone has on handover morning. If you are weighing up whether to bring in specialists at all, our wider range of cleaning services means we can usually fold the handover clean into whatever ongoing arrangement the client wants afterwards.
To talk through a build that is coming up to completion, call us on 0800 069 9055 or email [email protected]. Give us the rough programme and floor area and we will get someone out to price it properly, based in Gloucester and covering the whole county.
Frequently asked questions
What is the difference between a builder's clean and a post-construction clean?
A builder's clean is the rough clear-down a contractor does to get big debris and protection out of the way. A post-construction clean, sometimes called a sparkle or handover clean, is the detailed top-to-bottom finish that removes fine construction dust, paint and sealant marks, grout haze, labels and protective film, so the building is genuinely ready to occupy. The two are really the first and last stages of the same process.
How long does a post-construction clean take?
It depends on floor area, the number of floors, the finishes and how clean the site is left. A single refurbished shop unit might be a day; a multi-floor office fit-out or a large warehouse can run to several days with a full crew. We assess the site and give you a realistic timescale rather than a guess, because the state you leave it in makes a big difference.
Can you work around other trades still on site?
Yes. We regularly work evenings, weekends and nights to fit into the gap between trades finishing and handover, and on phased projects we clean floor by floor as each area is signed off. We work to the site's method statements and keep dust barriers intact around any areas still under construction.
Do you remove stickers, protective film and grout haze?
Yes, all of it. Removing barcode labels and blue protective film from windows, radiators and sanitaryware, along with clearing grout haze and cement film from new tiling and stone, is a core part of the detail stage. These are the jobs a rushed clean skips and a facilities manager always spots.
Is construction dust dangerous, and how do you deal with it?
Fine construction dust contains respirable crystalline silica from cut brick, concrete and plasterboard, which is a recognised occupational health risk with prolonged exposure. We use commercial vacuums with genuine HEPA filtration and work surfaces wet where possible so the dust is captured and removed rather than pushed back into the air, and our crews wear appropriate respiratory protection when dust levels call for it.
Do you cover the whole of Gloucestershire?
Yes. We are based at 88 Pillowell Drive in Gloucester and cover the whole county, from Cheltenham and Stroud out to the Forest of Dean and Tewkesbury. If your site is in Gloucestershire and coming up to handover, we can get to it.
Will you provide RAMS and insurance details for the principal contractor?
Yes. We produce a site-specific risk assessment and method statement and carry full public liability insurance. If your principal contractor needs our paperwork before we come on site, just ask and we will send it across ahead of the visit.
