"I cannot say enough good things about RAZR Restoration and owner Seth Paulson. I’ve used this company for multiple projects over the years—including a fire restoration on a commercial property, flood damage cleanup on one of my rental properties, and even some general contracting work. Every time, their team has been professional, responsive, and extremely thorough. One of the biggest tests came when someone crashed their vehicle into a property I own, causing substantial structural damage. I called RAZR, and they had a crew out the same day for initial cleanup and safety precautions. To my surprise, the entire project—including repairs, finishing, and paint—was completed within a week. That level of speed and quality is almost unheard of in the restoration industry. I know restoration companies sometimes get a bad reputation, but RAZR Restoration has truly earned my trust. Their professionalism and craftsmanship stand out, and I have referred them to many friends and colleagues who"

Additional DBAs - 1st Choice Restoration Inc, 1st Choice Restoration, 1st Choice Restoration of Moses Lake, 1st Choice Restoration of Walla Walla LLC, 1st Choice Restoration of Wenatchee.

"Everyone we encountered at 1st Choice was outstanding. They were quick to get to our house to look at the damage from a water leak. Once it was dried out and floors pick they quickly got it ordered and got to work on putting in new floors. Matt and his team went above and beyond on our project. The end result was better that I expected. Matt made sure we understood everything and took the time to explain everything that was going to be done and answered any questions we had. Can’t wait for the next project so we can have them come back. Hopefully not starting with a leak next time."

Mold Testing and Remediation questions, answered by experts

While the air inside your home should have some moisture—the ideal humidity level is between 30% and 50%—too much moisture can lead to issues. Some ways to tell if there’s too much moisture in your home include condensation inside your windows, mildew growth in the bathroom or mold on surfaces, peeling paint, or an uptick in allergy symptoms.

The most common reason for a smelly dishwasher is a dirty dishwasher filter. The filter is responsible for catching food while your machine is running to prevent clogs. Over time, that filter gets more and more filled with food particles. Cleaning your dishwasher filter monthly can keep the smell at bay.

Window sill mold can be harmful, but the severity depends on the type. Common household molds like Cladosporium or Aspergillus can trigger allergies, respiratory issues, or worsen asthma symptoms. However, black mold (Stachybotrys) can produce mycotoxins that can harm your health. Even less toxic molds should be addressed promptly to prevent health risks and property damage.

It is not advisable to stay in a house with black mold. Exposure to black mold, or any mold, can lead to health problems, especially for vulnerable individuals such as children, the elderly, or those with weakened immune systems. Black mold produces mycotoxins, which can cause respiratory issues, skin irritation, fatigue, and headaches. If black mold is detected, it is crucial to evacuate the premises, seek professional help for remediation, and only return once the area is thoroughly cleaned and confirmed mold-free by experts.

Mildew starts as a tiny spot, but if left untreated, it can severely damage your home as well as cause life-threatening health issues. Mildew eats away materials like wood and drywall and if left untreated can destroy entire walls and buildings. Mold sickness is almost a guarantee if you don’t tackle this problem as soon as it rears its head.
