"Noah scheduled an estimator to come to my house 30 minutes after my phone call. Moises came and gave me a reasonable price. He was prompt and courteous. The next day Hiram and Orge came to do the work. They were prompt and friendly. They did an excellent job removing the mold. Brian called me to keep me appraised of what they did and how long they will be leaving the dehumidifier and other drying equipment in the garage. This company is prompt, professional, and courteous and did an excellent job. I would definitely use them again."

"Ongoing water intrusion from our windows over the years led to mold issues throughout several rooms in the house. After bringing out three different companies to evaluate the situation, Steven and the team at Nexgen Property Restoration stood out right away. They were fair on pricing and offered a non insurance discount since we chose to handle everything out of pocket. With multiple areas needing to be opened up, that savings really helped. The remediation process was handled professionally from start to finish and the quality of work gave us the confidence to move forward with them for reconstruction as well. Having one company manage everything made the process a lot easier. The final result came out great and their warranty gives us peace of mind moving forward. Definitely recommend Nexgen if you?re dealing with paying out of pocket"

"SavOn/Ivan came out immediately and tested the area in question. I had mold in my dining room ceiling, not airborne thank God; but mold none the less needing remediation. SavOn completed the remediation in about 4 days and were very thorough, professional and attentive. Taylor in the office and Ivan in the field provided excellent service. SavOn was a little pricey but not as astronomical as the other companies. My project is not yet completed due to a lack of funds on my part but the cosmetic repairs will be completed soon and I'll keep you posted on the progress. Angel A"

Mold Testing and Remediation FAQs, answered by experts

Many caulk alternatives are safe for use in kitchens and food preparation areas, provided you apply them correctly and let them cure for the right amount of time. If you’re unsure about this step, call in a pro to do it for you. Silicone putty and caulk strips are often used around sinks and countertops due to their waterproof and flexible nature. Always choose products labeled as safe for kitchen use and follow the manufacturer's instructions for proper application and curing.

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.

Yes. You should use this product in a well-ventilated area because the fumes can be harmful. In addition, the product is poisonous if swallowed, so keep it out of reach of children. Wood finishing products that are oil based can cause irritation to your skin, so you should always wear gloves when handling it.

If you’ve spotted a skunk or know that one of these furry creatures sprayed one of your family members, your answer is fairly obvious. However, a skunky smell in your house that isn’t coming from these critters may be a sign of a dangerous gas leak. If you suspect this, leave your home immediately and call emergency services. It could also be a build-up of dangerous gas in your home’s septic system or plumbing. Call a professional plumber near you to make an assessment.

Humidity, moisture, and a lack of ventilation can all cause mold to grow on surfaces in and around your home.
