"I used Adviro for radon and VOC testing when buying a home and they were excellent. They were easy to get in touch with, quick to quote, and out on site a few days after I signed the contract. Communication was easy and clear, I could rely on them to do what they said they'd do, and the price was appropriate for the work. I wouldn't hesitate to recommend them or use them again."

"Curtis was quick to respond, showed up the next day on time, and was in and out in very little time. I even got my results the same day which was amazing. This is a rental property I had him test, and as they say, time is money. And having the testing & results that quickly with a letter stating it was clear of mold to cover me legally was exactly what I needed."

Lead Testing and Removal FAQs, answered by experts

No, a standard home inspection includes the basics and does not offer lead paint testing. Professional lead paint inspectors need specific licenses to perform these inspections, which not all home inspectors have. If you suspect lead paint in the home you are about to purchase, you will need to pay separately to have that done. If the findings come back positive, you may be able to negotiate with the buyer to cover the cost of the removal.

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Avoid disturbing suspected lead-containing materials and follow professional guidance on sample collection.

According to the Environmental Protection Agency (EPA), hazardous waste is generally classified into four main categories:

1. Characteristic Wastes: These exhibit at least one of four hazardous traits: ignitability (flammable, like gasoline), corrosivity (can rust or decompose materials, like car batteries), reactivity (unstable and can explode, like aerosol cans), or toxicity (harmful when ingested, like lead-based paint).

2. Listed Wastes: These are specific wastes from manufacturing and industrial processes that the EPA has officially designated as hazardous. They include byproducts from processes that use solvents, pesticides, and other chemicals.

3. Universal Wastes: These are commonly generated hazardous items that are subject to streamlined regulations. Examples include batteries, pesticides, mercury-containing equipment (e.g., bulbs), and some lamps.

4. Mixed Wastes: This category includes waste that contains both hazardous and radioactive components, making it subject to regulation by both the EPA and the Nuclear Regulatory Commission.

Professional testing for lead paint costs about $300, ranging from about $250 to $700, depending on the square footage, accessibility, and location. However, testing for lead paint with a DIY home-testing kit costs about $25, but doesn’t guarantee accurate results. The U.S. Environmental Protection Agency (EPA) recommends using a lead test kit that complies with the Lead Renovation, Repair, and Painting (RRP) Rule, which has strict criteria for ensuring a more accurate reading.

Common home surfaces to test for lead include:

  • Walls

  • Windows

  • Doors

  • Molding and trim

  • Railings
