Cleaning after renovation or construction work

The complete guide to a perfect post-construction cleaning

Renovations and construction work breathe new life into your spaces, but before you can enjoy the fresh look, a real challenge awaits: construction dust, paint splashes, adhesive residue, and cement haze. In this guide, we show you step by step how to thoroughly, efficiently, and sustainably clean your home, office, or practice after renovation work. We also provide a checklist and explain when it makes sense to hire a professional post-construction cleaning service.

Why professional post-renovation cleaning matters

Construction dust is very different from ordinary household dirt. It is extremely fine, spreads into every crack, and can affect your airways, furniture, and surfaces. After a renovation, you will often find:

• Fine plaster & cement dust
• Wood & paint residue
• Adhesive & grout smears
• Paint and silicone remnants
• Cement haze on glass and tiles

Without targeted cleaning methods, the dust quickly settles again, leaving streaks and residue behind. That is why a systematic renovation or post-construction cleaning is essential.

Step-by-step guide: How to master post-construction cleaning

1. Rough cleaning – the first step

• Remove packaging material, construction debris, and coarse residue.
• Use an industrial vacuum cleaner with a HEPA filter – standard household vacuums are not sufficient.

2. Fine dust removal on all surfaces

• Dust all horizontal surfaces: shelves, window sills, radiators, door frames.
• Use slightly damp microfibre cloths – they bind the dust instead of spreading it around.
• Do not forget walls, power outlets, and light fixtures – these are often where the most dust collects.

3. Window and glass cleaning

• Carefully remove paint splashes and mortar residue with a glass scraper.
• Use a pure water system or a high-quality glass cleaner for streak-free results.
• Thoroughly clean window frames, seals, and hinges – dirt accumulates heavily in these areas.

4. Cleaning floors and surfaces with care

Hard floors

• For tiles, vinyl, and laminate, mildly alkaline cleaners work well. Carefully remove paint splashes and mortar residue with a scraper.
• Avoid aggressive products to protect surface coatings.

Natural stone & delicate surfaces

• Use only pH-neutral cleaners.
• Always test on an inconspicuous area first.

Carpeted floors

• Spray extraction or a professional carpet cleaner is ideal for removing deep-seated dust and paint residue.

5. Thorough cleaning of kitchens & bathrooms

• Remove limescale and cement haze with mild, acidic specialist cleaners.
• Eliminate grease and paint residue with alkaline cleaners.
• Wipe all surfaces thoroughly dry to prevent water marks.

6. Improving air quality

After construction work, a large amount of fine dust lingers in the air.

• If possible, use air purifiers with HEPA filters to sustainably improve indoor air quality.

7. When to call in the professionals

For major renovations or delicate surfaces, it pays to hire a professional cleaning company like NW Clean:

• Pure water systems for streak-free glass cleaning
• Industrial vacuums with HEPA filters
• Specialist cleaning for natural stone, parquet, and glass
• Time and cost savings through efficient processes
