Older homes frequently have dusty basements that seem to attract dust continuously While homeowners may clean effectively, they often lack the know-how to prevent dust recurrence.
To clean a dusty basement use a shop vac, consider a sweeping compound to gather fine particles, dust hard-to-reach areas meticulously, and wipe surfaces with a vinegar and water solution. Prevent dust from returning to your basement by sealing concrete flooring, and introducing a HEPA-certified air purifier and dehumidifier.
Dirt and gravel are naturally dusty materials that, without proper basement ventilation, can create a mess and worsen allergies, as I’ve personally experienced. Let’s explore the issue of a dusty basement and solutions to mitigate it.
mastering dust cleanup in your basement
Growing up with allergies in an old house, I learned firsthand the challenges of maintaining a dust-free basement. My family dog also used to bring dust into the main home through his fur. You might imagine transforming that area into a nice play space for your kids but dealing with all that dust and musty smell can be intimidating.
One important lesson I’ve learned is that the key to ridding your basement of dust is to tackle the source itself—cleaning. Secondly, it’s entirely possible to prevent dust from returning effectively.
In the following sections, I’ll break down the essential steps to clean your basement, ensure its structural integrity, and, most importantly, maintain a dust-free space for your family.
Before You Begin: Lead, Asbestos, and Protection
Sometimes, dust buildup in older basements is due to crumbling walls. My childhood basement had crumbling walls, so my Dad and I used a limewash solution to protect them from mold while allowing them to breathe.
However, before starting any basement work, especially if it involves dust, test for asbestos and lead. Without testing, you won’t know if what’s chipping off the walls and creating dust could be hazardous. Depending on the test results, you may need professional help.
Vacuuming Upgrade: Why You Need a Shop Vac
Vacuuming dust from basements using a shop vac with a HEPA filter is the easiest and most effective way of efficiently removing dust. Shop vacs (on Amazon) differ from regular vacuums in their durability and versatility. Unlike regular vacuums or sweeping, they leave no dust or irritants behind and have a more powerful suction.
I’m also a fan of having a ‘dirty’ vacuum cleaner, so I’ll use my shop vac for areas like the basement, garage, and my workshop.
I’d recommend vacuuming the walls, ceiling, surfaces and windowsils to remove as much dust as possible. Also, fit a HEPA cartridge filter (on Amazon). These filters trap finer dust than the standard filter on shop vacs, and this should improve air quality and allergen levels.
In my quest for an effective solution to tackle the persistent issue of dust accumulation on my concrete basement floors, I stumbled upon a sweeping compound (on Amazon).
Made from a blend of sawdust, sand, oil, and water, it may sound unassuming, but trust me, it’s a game-changer. Sweeping compound traps and binds dust particles, preventing dust from being flung back into the air. Vacuuming dust on the other hand spreads dust into the air (which is also bad for my allergies!).
Using a sweeping compound is straightforward. Simply spread it evenly across the floor and then sweep it up for effective dust cleanup.
My next-door neighbor swears by using tea bags instead of purchasing a sweeping compound. Use tea leaves from old tea bags, mix with water, and scatter on the floor before sweeping to help bind the dust.
Don’t Miss a Spot: Dusting Those Basement Nooks
Once you’ve used your shop vac or sweeping compound, it’s time to start dusting. Use a duster to remove dust from surfaces such as shelves, furniture, and walls.
Be sure to pay attention to any nooks and crannies where dust can accumulate, such as behind appliances or corners.
Wipe all surfaces
After removing as much dust as possible from your basement, wipe down any hard surfaces, such as the top of a chest freezer, windows, or window sills.
For an affordable and effective cleaning solution, I typically use a vinegar and water mixture along with a microfibre cloth (on Amazon). Removing as much dust as possible is essential, as it helps prevent dust accumulation in the future.
Clean with Care: Avoiding Basement Damage
While I strongly advocate for thorough basement cleaning, many homeowners may not recognize the delicate nature of the basement environment. For example, basement walls are meant to breathe to uphold the structural integrity of your home’s foundation. Therefore it’s important to steer clear of cleaning methods that may harm this fragile ecosystem.
Never put Drilock (or any other waterproof membrane) on the walls of your basement
I’ve come across many online forums where homeowners are advised to use Drylok on their basement walls to reinforce them and prevent crumbling, which can lead to dust accumulation.
You should never use drilock or any other waterproof membrane on your basement walls. This can hinder the natural breathability of the concrete, trapping moisture and potentially causing damage to your home’s foundations.
Do not power wash your basement
I would strongly advise against power washing your basement. While it might be tempting, thinking it would easily remove dust, avoid spraying water on the walls, floor, or wooden framing.
Basements commonly face issues with humidity and mold buildup, and using power washers in the basement can lead to significant moisture problems.
Dustproof Your Basement: Effective Prevention
Whilst many homeowners are decent cleaners, a more intricate knowledge lies in how to actually prevent dust from returning to the home. Within this section, I’ll cover how you can cheaply and effectively prevent the formation of dust from within your home.
Before performing any structural work on your basement, check the basement building codes to stay compliant and safe.
Consider Painting your concrete floor
Bare concrete can create dust within the basement due to its porous surface, which gradually sheds fine particulates into the air and surroundings. Once you seal up or paint concrete floors, the formation of dust should cut down significantly.
Other advantages of correctly painting your concrete floor include reduced mold, fewer insects in your basement, and aesthetic reasons.
The best paint to use is a two-part epoxy paint (on Amazon) consisting of epoxy resin and a hardener. This will result in a durable finish whilst also creating a tight membrane that waterproofs the floor.
Replace the filter in your furnace or AC blower
HVAC system air filters prevent clogs and poor air quality. Neglecting a dirty air filter can lead to system issues and, notably, contribute to increased dust accumulation within your basement, exacerbating potential dust-related problems.
To change your furnace air filter, locate it first and check for size specifications without removing the old filter. Purchase the right-sized replacement filters and follow these steps: turn off the unit, remove the old filter carefully, ensure the arrow on the new filter indicates the airflow direction towards the furnace, and observe the filter while the unit operates.
Get a HEPA certified Air Purifier
An air purifier is a cost-effective and efficient solution for reducing dust buildup in your basement, and I’ve been using it for years.
HEPA room air purifiers (on Amazon) are engineered to cleanse the air in a room, targeting particles like dust, pollen, pet dander, smoke, and even airborne bacteria and viruses. HEPA (high-efficiency particulate air) air purifiers capture finer particles than regular air purifiers, making them particularly effective against dust formation.
Before buying an air purifier, measure the size of the basement. Many homeowners buy models that are too small and therefore ineffective.
the benefits of a Dehumidifier
Also, consider using a dehumidifier (on Amazon) to help reduce moisture levels in your basement. Moisture can contribute to the growth of mold and mildew, which can exacerbate dust and other allergens.
The most important things to look out for in a dehumidifier for the basement are:
- Pay attention to the ‘Energy Star’ ratings as it’ll be running constantly (also your power company might offer a $30 rebate for Energy Star dehumidifiers).
- Pay attention to the water tank capacity of the dehumidifier, as you’ll be regularly going down to the basement to empty it.
- Ensure the dehumidifier is big enough to service the size of your basement.
- Consider also buying a small humidity gauge (on Amazon) to get an accurate reading of humidity, as many dehumidifiers use cheap inaccurate models.
One of the most important things you can do to prevent dust is to ensure that your basement has adequate ventilation.
Poor ventilation significantly contributes to dust accumulation in basements. Consider installing fans or opening windows to allow fresh air to circulate through the space. This will help to reduce moisture levels, which can contribute to mold growth and dust accumulation.
Control Pet Dander
Pets can be a significant source of dust and allergens. Keep pets out of the basement as much as possible, and clean up after them regularly.
Remember to be consistent with your cleaning routine, maintain proper ventilation and humidity levels, and avoid storing or using items likely to produce dust.
