"I called to get a quote on basement mold remediation. They arrived the same day I called, and 2 workers showed up on time to do a walk thorough of my basement. They did not try to sell me on services I did not need and in fact, gave me tips on how I could do the mold remediation as a DIY project. They were professional and honest ... values you do not see in many contractors these days."

"This company is great at what they do. Used them twice. They helped removed asbestos tile and mold from my basement. They were quick, clean and most importantly got rid of the "bad stuff". They did such a good job the first time that I called them again when i unfortunately found mold in my crawl space. Both times eradicated all traces of mold. Would gladly use them a third time if needed!"

"Green Home solutions is a God send. The home I bought had mold from in the attic main level and basement. Dustin gave me such a good price, half of the other quotes. They came right out and within two days all the mold was gone and my new home smelled great! I have the peace of mind that my family is safe! And best of all the product is a non toxic enzyme and Dustin guarantees the mold will stay gone!!"

"Luis and his crew did great work removing large areas of adhered corkboard wall from two rooms. They were efficient and handled the removal, the drywall spackling and paint priming with minimal residual residue or mess in the house. The finished walls were just what we had hoped for. They were all a pleasure to work with! Communications via texts and the app made it easy to ask questions and follow up anytime."

Mold Testing and Remediation FAQs, answered by experts

In most cases, it's not worth the risk of buying a home with mold. You should carefully weigh the pros and cons before making a decision—and there are far more drawbacks than benefits. For one, buying a house with mold opens you up to health risks since mold can cause respiratory and allergic reactions. If the mold is widespread throughout the home, the cost to completely remove it, make necessary repairs, and prevent it from returning is often not worth the cost savings of buying a mold-infested home for a bargain.

Mold doesn’t require much airflow to make it out from behind walls and into your living space, making you sick. HVAC systems can actually pull the mold from behind walls and spread it through your home. While the mold may be out of sight, moisture transfer from the wall can also spread the mold from behind the wall into your living space and air. Any cracks in the walls or bad insulation only compound this effect. 

Turn off the water main immediately. Hire a professional plumber to check on your pipes and make any replacements so you avoid water damage. You don’t want to take any risks with flooding, so it’s best to consult a professional plumber as quickly as possible.

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

Mold on window sills is common, especially in damp or poorly ventilated areas. Windows are prone to condensation, which creates the moisture mold needs to grow. Dust, dirt, and other debris on the sills can further feed mold spores. While it’s not unusual, it should be addressed quickly to prevent further growth and potential health risks.
