Mold

Mold can grow in houses and apartments when there is too much moisture. People with allergies, respiratory conditions, or weakened immune systems may experience health effects from mold.

Getting Rid Of Mold

Finding and fixing the source of moisture is important. Common causes include:

  • Roof leaks
  • Leaking pipes or plumbing
  • Condensation from high indoor humidity
  • Indoor flooding

If you can’t find the source of moisture, or can’t fix it yourself, talk to a mold contractor.

If you rent, talk to your landlord. If they won’t help, call us at 608-242-6515.

Cleaning Up Mold

People with breathing problems, asthma, or weakened immune systems should not clean up mold because it could make their symptoms worse.

Radon

Radon is an invisible radioactive gas that has no smell or taste. It occurs naturally in the ground and leaks into houses through cracks in the foundation. Over the past four years, testing revealed that about half of the homes tested in Dane County had high levels of radon. Radon causes lung cancer.

How To Test Your Home For Radon

Testing is the only way to know if you have radon in your home. 

  • Hardware and home stores sell low-cost radon test kits (usually under $25).
  • Buy a test kit at one of our offices for $10. Cash or check only.
    • 2300 S. Park St., Suite 2010, Madison. Monday - Friday from 8:30am - 4:30pm.
    • 2705 E. Washington Ave., Madison. Monday - Friday from 8:30am - 4:30pm.
  • If testing shows a radon problem, you'll need to install a system that will prevent radon from building up in your home. The system should be installed by a certified mitigation contractor.
  • Radon reduction systems can reduce radon levels in your home by up to 99%. Radon reduction systems can be built into new homes.
