  • What To Ask References
    Interview Clients of Alameda County Lead Inspection Services

    It’s best to choose a Diamond Certified lead inspectors in Alameda County because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from lead-based paint inspectors in Alameda County and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified lead inspector in Pleasanton, Berkeley, Union City, San Leandro and Alameda or within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your Alameda County lead-based paint inspector.

    References provided to you by local EPA certified lead inspectors are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process, however. That’s because references given to customers by lead-based paint inspection companies are cherry-picked instead of randomly selected from all their customers. So the lead inspectors will likely give you a few customers to call that they know are satisfied.

    If you do call references on your own, specifically ask for a list of the lead inspection company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    • Were you satisfied with the lead inspection services from _(name of the Alameda County lead inspector)_?

    • your home was constructed before 1978. Homes built before 1950 are especially prone to lead-based paint dangers

Top 10 Requests
Lead Inspection Services Available in Alameda County

Lead inspection services are as varied as the needs of the customers they serve. However, there are some lead inspections that are more common than others. Those listed below are some of the more popular requests made of lead home inspectors in Alameda County and the rest of the Bay Area.

Lead Inspections in Alameda County
Lead inspections can be performed on lead-based paint on interior or exterior services, tap water, soil contaminated by paint chips and sanding paint, soil contaminated by leaded gasoline and even lead from industrial air pollution. Lead inspections can show the presence of lead and the amount of lead present in homes and businesses in Pleasanton, Berkeley, Union City, San Leandro and Alameda and beyond.

Lead Paint Testing 
Lead paint can be found in homes built before 1978. Lead paint that is chipping, cracking, bubbling, peeling, or disturbed during construction or sanding can release lead which can cause major health problems including brain damage, slowed growth, reproductive problems, nerve disorders and muscle and joint pain. Lead-based paint is especially dangerous to children, pets and adults with weakened immune systems.

Alameda County Lead Water Testing
Tap water that runs through lead plumbing, such as old lead pipes or lead solder, can become contaminated with dangerous levels of lead. Lead may also leach from new pipes, even those labeled as lead-free. During the first five years of a new pipe’s life, lead may leach from the piping. After five years, mineral build-up reduces leaching.

Lead Paint Test Kit
Home testing kits for lead are available. However, these home lead tests aren’t considered reliable by the EPA. These tests can give you an idea of whether lead is present in your home, and are especially useful for testing toys and single surfaces. You should rely on a professional lead inspection service in Alameda County for official test results.

Lead Paint House Inspection Checklist
Lead-based paint inspectors often abide by a house inspection checklist that ensures they test all necessary surfaces to determine if there is lead present in homes or facilities occupied by children.

EPA Lead Certification
The Environmental Protection Agency (EPA) provides certification programs for lead contractors to help them effectively and efficiently locate and evaluate sources of lead poisoning.

Lead-Based Paint Risk Assessment
Lead-based paint risk assessments are inspections of homes for deteriorated paint that need to be tested for lead. A complete lead assessment should include testing of the soil around the home for the presence of lead. Lead risk assessments are usually performed before the sale of a home. By law, you have 10 days to secure a lead risk assessment before your home sale contract is finalized.

Soil Lead Testing in Alameda County
Soil can become contaminated by lead through the scraping, sanding or leaching of lead-based paint; or it may have been contaminated by coming into contact with leaded gasoline before it was outlawed in 1978. Testing soil for lead proves if lead is present and how much is there.

Lead Testing for Childcare Facilities and Schools in Alameda County
Children are the most common victims of lead poisoning. Schools and childcare facilities in Oakland, Fremont, Hayward, Berkeley, San Leandro, Alameda, Union City, Pleasanton, Newark and Dublin and other areas that were built before 1978 should be tested for lead present in paint, tap water and soil.

Lead-Based Paint Home Inspection Reports
Home inspection reports should be presented for all homes and buildings tested for lead. These inspection reports should detail what areas and substrates were tested, whether lead was found, and the amount of lead found. The lead reports should also contain suggested steps for homeowners to take to remove the lead found in their homes.

Frequently Asked Questions
Frequently Asked Questions About Lead Inspections and Lead Contamination

Q: Why choose a Diamond Certified lead inspection company?
A: Diamond Certified helps you choose a lead inspection service with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only lead inspection services rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified lead inspector.

Q: What is lead?
A: Lead is a toxic metal. However, it was used in many household products until it was listed as a public health hazard. The EPA has listed lead as a toxin since about 1980, and is now working to reduce the amount of lead used in consumer products. Other countries, including France, Germany, Australia and Japan, banned the use of lead paint in residential homes as early as 1870. Today, almost eight in 10 reports of lead poisoning stems from lead paint used in apartments and homes built before 1978.

Q: Where is lead found?
A: Lead is most commonly found in buildings (including homes and apartment buildings) that were built before 1978. These buildings may have many sources of lead contamination, including lead paint on walls and other surfaces, soil that was contaminated by paint chips from the exterior of the home or leaded gasoline, and old lead pipes or lead solder that leaches lead into the tap water. Newer homes may also experience lead contamination from new pipes. Even so-called lead-free pipes may contain up to eight percent lead. This lead can leach into tap water for up to five years after installation, or until minerals build up on the inside of pipes and slow down the leaching process.

Q: Why is lead paint considered dangerous?
A: Lead can be introduced to the body through swallowing, inhalation or absorption through the skin. Children are most prone to lead toxicity because they may ingest paint chips, chew on painted surfaces or come into contact with lead dust. Lead exposure can cause brain damage, damage to the central nervous system, learning problems and behavior problems in children, lower IQ, stunted growth in children, hearing problems, headaches, reproductive problems, birth defects, high blood pressure, digestive problems, nerve disorders, memory problems and muscle and joint pain.

Q: What is a lead inspection?
A: Lead paint inspection is a series of tests for lead provided by a certified lead inspector. These tests run the gamut from lead dust testing, lead paint testing and testing of water for lead. Talk with your local lead testing company to learn which lead tests may be required for your home.

Q: Is lead dust testing a part of a lead inspection?
A: Lead dust is often tested as part of lead inspections. Lead dust is invisible to the human eye, but can easily be tested for the presence of lead. Confirm with your lead inspector that he or she will be testing for the presence of lead dust.

Q: What is a final lead inspection?
A: Final lead inspections are those performed after the removal of lead-based paint or contaminated surfaces. Final inspections are an important part of the lead removal process, and they should be performed by certified lead inspectors that are not associated with the lead removal contractors to avoid any chance of a conflict of interest.

Q: What should I know before buying an older home?
A: Homes built before 1978 may contain lead paint. Sellers must disclose the presence of lead-based paint in all homes and buildings. However, the seller is not required to test homes for lead or to pay for lead inspections. Sellers should provide lead inspection reports if any have been conducted. Your real estate agent should also share with you the potential hazards of lead paint. Keep in mind that lead-based paint disclosure doesn’t apply to foreclosed homes. As a home-buyer, you may hire a lead inspector to perform a lead inspection.

Q: How do I know if lead paint is present in my home?
A: You must have a certified lead inspector perform tests on your home. These may be water testing for lead in tap water, a lead risk assessment which looks for deteriorated paint, lead-based paint inspection on all painted surfaces inside and outside of the home, and lead hazard screening for homes in good condition with little flaking or chipping paint.

Q: Is a home lead testing kit a good alternative to professional lead inspection?
A:  Home lead testing kits are available, but they can only give you an idea of whether lead is present. The EPA and HUD do not allow chemical spot testing or home lead testing to be used as an official evaluation method of lead inspection. Kits may give unreliable results due to the layers of new, unleaded paint that may cover old lead paint.

Q: How much does a lead inspection cost?
A: Lead inspections usually cost $300 or more, depending on the size of the home and the lead testing required. Call your local lead inspection company for a bid on the lead tests your home or building may need.
