Cleaning carpets in an older home with lead paint: what the EPA advises
Updated · KeystoneProGuide editorial team
Does lead paint matter when you clean carpet?
In a house built before 1978, it can. The U.S. Environmental Protection Agency says homes from before that year are more likely to have lead-based paint, that dust and chips from that paint are one of the most common sources of lead exposure in homes, and that settled lead dust can re-enter the air when a home is vacuumed or swept or when people walk through it. Carpets and rugs collect that dust. The EPA's advice is not to stop cleaning them but to clean them in a particular way, which depends on whether you can see paint debris.
How many Pennsylvania homes are old enough?
A large share. The Census Bureau estimates that a quarter of Pennsylvania's housing, 25.0 percent, was first built in 1939 or earlier, decades before the 1978 cut-off, and in Philadelphia the figure is 39.9 percent. The Census profiles used for these guides do not give a figure for homes built before 1978, so the true share of homes that may have lead paint is larger than these numbers and cannot be read from them.
The EPA says about three-quarters of U.S. homes built before 1978 still contain some lead-based paint. It also says that lead paint in good condition is usually not a problem, and that children can live safely in such homes as long as the paint and surfaces are in good condition and kept clean.
How should carpet be vacuumed in a home with lead paint?
The EPA's guidance turns on what you can see.
- No visible dust or debris from chipping or flaking paint: a standard vacuum cleaner is fine.
- Visible paint dust or debris: use only a vacuum with a HEPA filter, and do not dry sweep.
It recommends cleaning the home weekly to keep down dust that may contain lead. On hard floors next to carpet, it says to wet mop, and not to use vacuums with beater bars or polishing machines that may wear away painted surfaces. The Asthma and Allergy Foundation of America makes a related point about vacuums in general: poor-quality vacuums can put dust back into the air.
Can you shake out rugs or deep clean stains?
Not by shaking. The EPA says do not shake or beat carpets and rugs in a home with lead dust, which rules out the usual habit of taking a rug outside to beat it. For stains, it says to wet scrub or use steam-cleaning methods. For hard surfaces it warns against steel wool, scouring pads, abrasive or solvent cleaners that may dissolve paint, and rubbing spots excessively.
Where does the dust come from, and how do you keep it out?
The EPA names worn paint on surfaces that rub together, such as doors and window sills, as a common source of chips and dust, and says renovation or repair that disturbs old paint can create large amounts of it. Lead in soil can also be tracked indoors on shoes.
Its advice for keeping it out matches what the carpet industry recommends for keeping carpet clean:
- Doormats and shoes. The EPA says to put doormats outside and inside every entry and take shoes off before coming in. The Carpet and Rug Institute, the carpet makers' trade association, gives the same advice to stop dirt at the door: mats inside and out, and shoes off.
- Pets. The EPA suggests wiping pets' fur and paws after they have been outside.
- Work clothes. It says people whose jobs or hobbies expose them to lead dust should change clothes and shoes before coming home and wash those clothes separately.
- Peeling paint. It says to inspect painted surfaces, especially windows, doors and stairways, and to clean up any chips right away with a damp paper towel.
What should you ask a carpet cleaning company?
- Will you vacuum with a HEPA-filter vacuum? The institute's residential standard calls vacuuming before cleaning an essential step. In a home with visible paint debris, the EPA's rule is HEPA only.
- Will any of the work disturb paint? The EPA says anyone paid to do work that disturbs paint in housing built before 1978 must be certified and trained in lead-safe work practices. The EPA's page does not say whether carpet cleaning counts; if a job will go further than cleaning, ask whether the company is certified.
If you rent a pre-1978 home, the EPA says your landlord or property manager must follow the lead-safe renovation rules when doing work that disturbs paint.
What about older homes after a flood?
The EPA's flood guidance adds that older homes may have building materials containing asbestos or lead, and points people cleaning up after a flood to its advice on recognizing both. In an older house, that is worth reading before tearing out wet carpet and pad.
Cleaning it yourself or hiring covers the home routine, how to choose a carpet cleaner covers credentials, and the Philadelphia guide covers the city, where 39.9 percent of homes date from before 1940. Local companies are on the carpet cleaning directory page.
