"I recently had a leak in my ceiling and contacted Voda for water restoration services. From the initial assessment to the completion of the job, their team was professional, responsive, and extremely courteous. They carefully opened the affected area of the ceiling and set up fans to ensure proper drying, taking every precaution to minimize disruption to my home. What really stood out was their attention to detail and exceptional customer service—every step was clearly communicated, and they made sure I was comfortable and informed throughout the entire process. I truly appreciated the care they took in handling everything. I would highly recommend Voda to anyone in need of water damage restoration."

"A soft wall due to improperly installed gutter by some other entity or homeowner caused water to constantly leak into the wall from the exterior roofline. This soft wall grow moldy and become riddled with pests/bugs. The contractor identified the potential issues, agreed to explore and open the walls and discuss the conditions, made sound recommendations for repair and did exactly what was noted in the repair (replaced a load bearing exterior wall, fixed the sill plate, completed the roof, shingles etc. and closed up the walls on the inside with insulation and sheet rock.). The work was timely, well done, the workers were clean as they did the job and kept the rest of the property clean. The manager of the job David Apel was and is an excellent communicator with phone/email/text and photos of processes and progress. I am going to use this company in my own investment endeavors on other properties and projects given the level of finished work, the timing and especially the level of detailed communication."

"Everything went perfectly. They were prompted everyday and worked around my schedule. They went the extra mile for detail and attention. They were not the cheapest, but they did perform the most work for the lowest price. The competition all wanted more money for cleaning and rebuild. I would recommend them for anyone looking for mold remediation and build back."

Biohazard Remediation FAQs, answered by experts

Whether it's safe to stay in a house with water damage depends on the severity of the issue. If the damage is minor, such as from a small plumbing or window leak that is caught early and hasn't affected the electrical system or led to mold, it is likely safe to stay. However, for major water damage from flooding or standing water, it is not safe to remain in the home. The primary risks include mold growth, which can begin within one to two days and poses a serious health risk; structural damage that can weaken your home's integrity; and electrical hazards. It is strongly recommended to relocate until a trained professional has inspected the damage, dried the area, treated any mold, and confirmed the home is safe to return to. Your insurance company may be able to help with the cost of alternative housing while repairs are being made.

Mold loves moisture, so prolonged high humidity levels or standing water can trigger mold growth. Mold also needs a food source to grow on, such as wood, fabric or another material. However, it's moisture that's most important for mold growth, which is why you want to keep humidity levels low.

To neutralize mildew smell, you can use natural deodorizers like baking soda or activated charcoal. Baking soda absorbs odors; sprinkle it liberally on the affected area, let it sit for a few hours, then vacuum it up. Activated charcoal, available in pouches, works similarly. Vinegar, with its natural acidic properties, can also neutralize odors. Mix equal parts water and vinegar, spray the affected area lightly, then blot it with a dry cloth. Enzymatic cleaners are effective too, breaking down odor-causing compounds.

Mold loves a moist environment, so the best way to keep it from returning is to keep your machine as dry as possible. Take laundry out of the machine as soon as you can after a cycle finishes. If your laundry room is humid, consider using a dehumidifier or at least running a fan to increase airflow.

It's also a good idea to leave the washing machine door open when it's not in use, to improve airflow and keep the interior dry.

While mold in the bathroom can appear black, it isn’t always the dangerous black mold strain Stachybotrys chartarum. This type of mold typically appears after a flood or a long-term leak. If you suspect black mold, you should get it tested by a local mold testing service to determine whether it’s safe to remove yourself.
