You have waited months, maybe years, for this day. The keys are in your hand, the paint is fresh and the tiles are shining. Then you run a finger along the windowsill and it comes away grey. Cabinets hold white powder and a film returns minutes after you sweep.

That is why post-construction cleaning services in Nairobi are part of almost every smooth handover. A house that looks finished is not the same as one ready to live in, and it is one of the most common surprises for new homeowners, landlords and developers.

Why a brand-new house still needs post-construction cleaning

A building site is one of the dirtiest environments a home goes through. Cement, plaster, paint, adhesives and grout linger long after the crew leaves, including:

• Fine construction dust in vents, ceiling fans and light fittings
• Paint splatters and cement stains on floors, glass and tiles
• Sticker residue and protective film on windows and appliances
• Grout haze that dulls new tiles
• Debris hiding in cupboards and ceilings

Sweeping will not fix this, and wiping dust with a damp cloth creates a scratchy paste. Proper new house cleaning needs the right tools, products and order of work.

The hidden problem: fine dust

Construction dust is much finer than everyday dust and often contains cement and silica particles. It can irritate the eyes, nose and throat, especially for children and anyone with asthma.

Professionals remove it in layers: high surfaces first, then walls and fittings, floors last. Industrial vacuums and microfibre materials trap dust instead of pushing it around.

Areas that need special attention

• Floors: Tiles, marble, timber and vinyl each need a different method, and the wrong one can cause permanent damage. Our floor, window and exterior cleaning team matches the method to the surface.
• Windows: Paint specks and cement spots are stubborn, and tracks collect hard-to-reach dust.
• Kitchens: Cabinets, countertops, extractor hoods and appliances must be sanitised before you cook. A kitchen and bathroom deep clean covers this.
• Bathrooms: Cement marks, silicone smears and mineral stains cling to fittings and mirrors.

Routine vs. post-construction cleaning

Routine cleaning maintains a lived-in space with mops, cloths and a domestic vacuum. Post-construction cleaning is a multi-stage restoration using industrial vacuums, scrapers and surface-safe products, often taking a full day or more. One keeps a home fresh; the other makes it move-in ready.

Your pre-move-in checklist

• Dust ceilings, vents and fans, then walls, switches and door frames
• Remove paint, cement and sticker marks from glass
• Vacuum and mop floors using the right method for each surface
• Have the water tank cleaned and disinfected, since new tanks often hold construction dust
• Consider fumigation and pest control while rooms are still empty

When to book

Developers should book after all building work is complete but before final inspection. Homeowners should book after the builders leave and before furniture arrives. Landlords should book after renovation and before viewings; short-stay hosts can add our Airbnb and hospitality cleaning. Aim for a few days before move-in.
