"Adisa Enterprises was excellent! My project required removing a water-damaged wood floor exposing asbestos tiles underneath. Adisa removed the wood flooring, asbestos tiles, and mastic and disposed of them. They were very diligent, remediating the asbestos consistent with legal requirements. They installed the new sub floor smoothly so the replacement flooring went down easily. Highly recommend"

"I love my basement now! They removed all of the asbestos flooring, adhesive etc. and installed my new floor in 2 days. The employees were very respectful and worked efficiently. They had said 3 days but they hustled and did it in 2."

"Gina Raspa was wonderful to work with.  She responded within 24 hours to my email and she performed the testing within 4 days of my first contact.  Everything went smoothly thanks to her willingness to respond as soon as possible.
The news was much better than we expected and Gina gave me 3 recommendations for companies who could successfully perform the clean-up.
Thanks to Gina, we were able to move the family into the house without fear of future health issues.
I give Gina and her company the highest ratings because she earned them.

"Rodney is great. Very responsive, reasonably priced, and sends reports very quickly. He does all my lead paint inspections for all my rental properties. I've worked with several lead inspectors and won't use anyone else. Highly recommended."

"Inspector responded promptly to my service request. Came on time and was very descriptive while addressing our concerns. He even provided some information on seperate home items that were not part of the service we requested. Also, very respectful of our property. (He actually took his shoes off because we had new carpet.) WIll use again. Thank you!"

"These guys were AWESOME. They arrived within 90 minutes, assessed, estimated, and had equipment already with them to handle our flooding. They moved the furniture, explained how it all worked, came back half way through (it was a 3 day process), moved the fans, and then put it all back when they were done at the end of the 3rd day. If every company worked like this - had staff as professional, friendly, and reassuring as these guys - there'd be no need for a better business bureau! Love them. Don't hesitate to use them!"

Lead Testing and Removal FAQs, 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.

While not all homes built before 1978 contain lead paint, enough do, so you’ll still want to test to be on the safe side. The federal government banned lead-based paint for homes in 1978, but your state may have banned lead before that time. Around 24% of homes built between 1960 and 1977 contained lead-based paint, while 87% of homes built before 1940 contained lead-based paint.

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

Determining if your water main contains lead involves a few steps. First, check the age of your property, as homes built before the 1980s might have lead pipes. Contact your water utility company for information on your service line material. Then, you can hire a professional plumber to conduct an inspection or use a lead testing kit to analyze water from the main line.

“Testing” can start with your senses: Assessing your water’s appearance, taste, and smell can all be good first steps. The best way to know for sure what’s going on with your water is to use a well water testing kit, which can tell you about the specific levels of bacteria, dissolved solids, and hardness of your water with precision. Have a pro test your well water at least once per year.
