How to Clean Builders’ Dust

Builders’ dust is a common by-product of construction and renovation work, and it can be a challenge to remove. This fine, powdery residue settles everywhere, from floors to furniture, often infiltrating hard-to-reach places.

Proper cleaning techniques are essential not only to restore the appearance of a space but also to protect the health of those exposed to it, as dust can cause respiratory issues and exacerbate conditions like asthma. With this in mind, this article presents a useful guide on how to thoroughly clean builders’ dust caused from renovation and construction jobs in properties such as homes, offices, commercial buildings, hotels, schools and nurseries.

Top Tips For Cleaning Builders’ Dust 

Step 1: Start with a Dry Dust Removal

The first step in a builders clean is to dry dust all surfaces, including walls, furniture, and windowsills, with a microfiber cloth. Avoid using regular dusters as they tend to spread the dust around rather than capturing it.

A single home renovation project can produce up to 23 kilograms of dust on average, meaning it is essential to tackle the initial layer with a tool that efficiently traps dust particles. If left unchecked, this dust can settle into cracks, crevices, and even ventilation systems, leading to long-term air quality issues and potential respiratory problems for those in the property.

Step 2: Use a High-Quality Vacuum

Next, vacuum the floors and carpets using a vacuum cleaner with a HEPA filter, which traps fine particles. Builders’ dust is finer than typical household dust, and traditional vacuums may not be effective.

Pay attention to corners, skirting boards, and other areas where dust can accumulate. In areas with exposed pipework, such as in the kitchen or bathroom, ensure the vacuum nozzle reaches behind pipes and fixtures, as dust can settle there. When dealing with plumbing installations, it is important to ensure no dust gets trapped in vents or filters, as it could impact water flow and drainage.

Step 3: Wet Cleaning for Floors and Surfaces

Once the initial dry dusting is complete, wet cleaning is crucial. Mop hard floors with a mixture of warm water and a mild detergent to pick up the remaining dust.

Post-construction dust can linger in the air for up to 3 months, so multiple rounds of wet mopping may be required to fully remove it. Be sure to clean windows and window frames, as dust can settle in tracks and frames.

Step 4: Air Filtration

Lastly, improve air quality by using air purifiers with HEPA filters to trap airborne particles. This is particularly important if anyone in the household suffers from allergies or asthma, as more than 50% of UK households report allergies triggered by dust or other particles in the air.

Step 5: Clean Ventilation Systems

As a final step, you can consider cleaning your property’s ventilation systems, including air vents, extractor fans, and ductwork. These systems often collect builders’ dust, which can then circulate through the air even after surface cleaning is complete.

Ensuring your vents are dust-free will help improve air quality and reduce the chance of ongoing dust contamination. In London’s densely built areas, proper ventilation is essential to maintaining healthy air circulation, particularly in renovated flats or office buildings where dust can settle in small, enclosed spaces.

The Bottom Line

In conclusion, removing builders’ dust requires a combination of dry dusting, vacuuming with a HEPA filter, and wet cleaning to ensure your space is truly dust-free. Regular maintenance and checking areas such as plumbing vents can help prevent ongoing dust issues.
