Lead-based paint was banned in the United States in 1978, however, it is likely that homes built before this year contain lead paint. If you are concerned about the presence of lead paint in your home, the safest way to identify it is to hire a certified inspector or risk assessor to conduct an inspection. Alternatively, you can assume your home contains lead-based paint and take the appropriate precautions, especially if your home was built before 1978. There are also at-home lead test kits available for purchase.
| Characteristics | Values |
|---|---|
| Age of the building | Older buildings are more likely to contain lead-based paint. 87% of homes built before 1940 have some lead-based paint, and homes built before 1978 may contain traces of lead paint. |
| Renovation history | If the building was renovated, it's possible that any traces of lead paint were addressed. |
| Paint condition | Lead-based paint is hazardous if it's damaged, deteriorating, or on a high-risk surface. Signs of damaged paint include paint chips, peeling, flaking, and a chalky residue. |
| Paint appearance | Alligatoring, or cracking and wrinkling of paint in a pattern reminiscent of gator scales, may indicate the presence of lead. |
| Presence of children | Young children are especially at risk of lead exposure, which can cause developmental problems. |
| Symptoms of lead poisoning | Lead poisoning can present in many different ways, including nonspecific symptoms. |

What You'll Learn
Assume lead-based paint if your home was built before 1978
If your home was built before 1978, it is likely that there is lead-based paint somewhere in the property. Lead was commonly added to paint before it was banned in 1978 in the US due to its serious health risks. It was a cheap and effective way to manufacture paint, improving its appearance, durability, and drying time.
It is important to identify the presence of lead paint to protect your family's health and safety. If the paint is in good condition (no peeling, chipping, cracking, or flaking), you may be able to paint over it with encapsulants, which are special paints that prevent lead-containing paint from flaking or producing hazardous lead dust. However, if the paint is damaged, you should contact a lead removal company as soon as possible to safely remove it. In the meantime, you can reduce lead exposure by removing your shoes at the front door, regularly dusting and cleaning your home, and maintaining a healthy diet.
There are a few ways to determine whether your home contains lead paint. Firstly, you can research the age, source, and condition of any paint in your home. Secondly, you can purchase a DIY lead paint test kit, although these may not be as accurate as professional testing. Finally, you can hire a certified inspector or risk assessor to conduct an inspection and provide a risk assessment. They will take material, paint, water, soil, and dust samples from your home and send them to a lab for testing. This will tell you if there are any lead hazards in your home and advise you on the necessary actions to address them.
If you notice any signs of deteriorating paint, such as alligatoring (cracks and wrinkles forming a pattern reminiscent of gator scales) or a chalky residue when it rubs off, you should have your paint tested as soon as possible. These signs may be harder to spot if they are covered by layers of new paint, so be sure to check areas that are often neglected, such as closets, unfinished basements, and behind appliances.

Look for multiple layers of paint on surfaces
If you're concerned about the presence of lead-based paint in your home, it's important to take proactive steps to address any potential hazards and ensure a safe living environment. While modern household paints do not contain lead, there is no visual way to rule out the presence of lead in paint. Therefore, it's crucial to inspect painted surfaces and take appropriate measures.
One key indicator of lead-based paint is the presence of multiple layers of paint on surfaces, especially in older buildings constructed before 1978. Lead paint was commonly used in residential buildings before its ban in the late 1970s due to its durability and colour retention properties. As a result, older homes may have multiple layers of paint, with lead-based paint covered by newer paint.
When inspecting for lead-based paint, pay close attention to high-risk areas and surfaces, including windows, window sills, railings, doors, doorways, frames, stairs, floors, baseboards, cabinets, porches, and handrails. These surfaces typically experience regular wear and tear or moisture exposure, increasing the likelihood of paint deterioration and lead exposure.
If you notice multiple layers of paint in these high-risk areas, it's essential to take further steps to confirm the presence of lead. Home testing kits can be useful, but they may only detect lead in the outermost layer of paint. For more accurate results, consider hiring a certified lead inspector or risk assessor who can utilise specialised equipment, such as handheld XRF analysers, to comprehensively check all painted surfaces.
Additionally, historical documentation, such as property records, maintenance logs, or disclosure forms, can provide valuable insights into the materials used during construction or any documented instances of lead-based paint application. However, while historical documentation can be informative, it should be complemented by comprehensive testing and assessment conducted by professionals to ensure accurate identification and appropriate mitigation measures.

Conduct a visual inspection of walls, doors, stairs, and baseboards
If your home was built before 1978, it may contain traces of lead paint on the walls, doors, stairs, and baseboards. If your home was constructed after 1978, it is highly unlikely that it contains lead-based paint. If you are unsure, you can perform a visual inspection to check for signs of lead paint.
Firstly, determine if your home has been renovated. If your home has a modern, updated appearance, it is possible that any traces of lead paint were dealt with during the renovation. If you are renting, you can contact your landlord to ask about the presence of lead paint.
When conducting a visual inspection of walls, doors, stairs, and baseboards, look out for signs of deterioration. Lead paint cracks in a unique way, with the paint cracking and wrinkling to form a pattern reminiscent of alligator scales. This is known as "alligatoring". Lead paint also produces a chalky residue when it rubs off, which is another way to identify it. However, if your home has been repainted multiple times since the 1970s, these signs may be covered up.
Inspectors will also look for a powdery texture around windows, doors, and walls to identify deteriorating paint and potential hazards. They will also examine paint chips and dust using special equipment like an XRF analyzer. If you are conducting a DIY inspection, you can purchase a home lead test kit from most retail hardware stores. However, these tests have a poor accuracy rate.
If you find any signs of lead paint, you should have your paint tested as soon as possible. Even if you don’t notice any visual signs of lead, it is still recommended to have your home checked by a professional.

Hire a certified inspector or risk assessor
If you suspect that your home may contain lead-based paint, the best course of action is to hire a certified inspector or risk assessor. Lead-based paint was commonly used in homes before 1978 due to its durability and moisture resistance. While it has been banned since then due to its health hazards, millions of homes in the United States still contain lead-based paint, especially older homes.
A certified lead-based paint inspector or risk assessor can conduct a thorough inspection to determine the presence and location of lead-based paint in your home. They will collect samples of paint, water, soil, and dust, and send them to an accredited laboratory for analysis. This process ensures an accurate and reliable assessment, which is crucial for developing a plan to address any potential hazards.
The risk assessor will also conduct a comprehensive risk assessment to identify any current lead hazards in your home, including lead in paint, dust, or soil. They will advise you on the necessary actions to mitigate these hazards and ensure your family's health and safety. This is particularly important if you have young children, as they are more susceptible to lead exposure through touching and ingesting paint chips or lead dust.
By engaging the services of a certified inspector or risk assessor, you can be confident that your home will be thoroughly evaluated for lead-based paint. They will provide you with the necessary information and guidance to make informed decisions about any renovation, repair, or painting work that may be required to create a safe living environment for you and your family.
While there are DIY lead test kits available, they may not be as accurate or thorough as professional testing. Therefore, hiring a certified inspector or risk assessor is the recommended approach to address any concerns about lead-based paint in your home.

Recognise symptoms of lead poisoning
Recognising the symptoms of lead poisoning can be challenging, as they are often similar to those of other illnesses. Lead poisoning may occur suddenly after a single high dose of lead or develop slowly over time due to repeated exposure to small amounts. Children are primarily at risk, as they tend to explore objects and surfaces by putting them in their mouths. They may swallow paint chips or inhale lead dust, which can settle on surfaces and in the soil from leaded gasoline or paint.
In children, symptoms of lead poisoning can include:
- Vomiting
- Seizures
- Impaired mental development
- Behavioural issues
- Learning difficulties
- Poor growth
For adults, symptoms may be less obvious, but they can still experience serious health issues due to lead poisoning, including:
- High blood pressure
- Digestive problems
- Joint and muscle pain
- Memory loss
- Mood disorders
- Headaches
- Reduced sperm count in men
If you suspect lead poisoning, it is crucial to seek medical help immediately. Contact your local poison control centre or emergency services for guidance. Do not wait for symptoms to develop or worsen, as lead poisoning can have severe and lasting health consequences.
