"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."

Lead Testing and Removal questions, answered by experts

Properties should be tested for lead every 2-3 years, especially if they are older, have undergone renovations, or show deterioration of paint or interior finishes.

DIY lead testing kits are available, but they often lack the accuracy and reliability of professional services. Professional testing is recommended for more accurate results, as properly certified testers can provide a thorough analysis, clear recommendations, and the necessary legal documentation if remediation is required.

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.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

Professional lead removal involves identifying and safely removing or encapsulating lead-based paints and materials, using specialized equipment, and following strict safety procedures to minimize exposure and contamination.
