Construction work can often leave dust on the inside of your home.

Adding onto a home or remodeling a room creates a great deal of dust. Cutting and sanding construction materials -- including drywall, tile, masonry or wood -- leaves dust particles floating in the air that settle on most surfaces in the house. Dust covers floors, furniture and walls and makes the new-construction area, along with existing structures, look dirty. Removing the dust is necessary to prevent inhaling irritating dust particles and to reveal the beauty of the home that lies under the dust.

Step 1

Put on safety goggles and a dust mask.

Step 2

Open a window in the room and set a fan in the window with the air flowing out to ventilate small dust particles that float after you disturb them.

Step 3

Equip a shop vacuum with a HEPA (high-efficiency particulate air) filter.

Step 4

Turn on the shop vacuum and suck up the construction dust with the end of the vacuum hose. Begin at the doorway to the room to avoid walking over the dust and kicking up the particles. Starting at the edge of the room protects floors from scratches as you walk over them to clean, which is especially important for flooring that is prone to scratching.


Step 5

Move the shop vacuum over the floor using a side-to-side motion. Only walk on dust-free areas of the flooring. Empty the vacuum often and clean the HEPA filter to keep the shop vacuum efficient.

Step 6

Fill a bucket with water. Submerge a sponge mop in the water and squeeze out as much water as possible, so the sponge is barely damp. Place the damp sponge mop on the ceiling in the corner and pull the mop along to remove the dust from the ceiling. Make row-by-row passes over the ceiling. Rinse the mop and repeat until the ceiling is free of dust. Dump the water and refill the bucket as the water clouds with dust.


Step 7

Place the damp mop on the wall at the ceiling line and drag the mop down the wall to remove the construction dust from the walls. Rinse the mop and continue to wipe the walls with the damp mop until the walls are dust-free.

Step 8

Wet a microfiber rag with water and wring out the excess water, so the rag is just damp. Wipe cabinet faces, appliances, furniture and sections of the wall that you could not access with the mop. Start at the highest points in the room and work down toward the floor. Rinse the rag often and change the water to prevent redistributing particles of construction dust.


Construction dust continues to settle for days or weeks after construction has been completed. Repeat the process as new construction dust settles over the room. Humid areas have less dust settling over time than dry areas because the dust absorbs the moisture and settles faster.


Avoid sweeping construction dust because sweeping disturbs the settled dust and causes it to float in the air.
