We are professional service providers that take pride in our work. We work hard to provide the best service possible with integrity and accountability. We would love to help you so give us a call today!

"I had a black mold problem at my home. The evaluator gave me a price before any work was done. The crew simply went above and beyond the call of duty in the remedial process. On a scale of 1 to 10, I would give them a 15! Every member of the crew was extremely hard working, from Wilbur down to his 14 year old grandson. I like dealing with small, local, business, and I consider myself most fortunate and blessed to have found Will Hull and crew. I would hope none of my friends develops a black mold situation, but f they did, I would immediately recommend Wilbur Hull Nano Cleaning , They only perform necessary remediation to safely treat the house, thus saving money for the customer. They treated the entire house, which was a pleasant surprise to me. Overall, Wilbur Hull Nano Cleaning was superb! Pricing was Fair & Reasonable."

WHY CHOOSE US When life throws the unexpected your way—whether it’s a burst pipe, a devastating fire, or stubborn mold taking hold—you don’t have to face it alone. Exceptional Restoration is here to help, 24/7. We know how stressful and overwhelming these situations can be, which is why our team is committed to being by your side every step of the way. From the moment you call, we spring into action. Whether it’s the middle of the night or a holiday weekend, we’re just a phone call away. Why? Because disasters don’t wait, and neither should you.

"We were VERY disappointed with this company on multiple levels. When I balked at the estimate for the hardwood floor work, their phone rep claimed the job included a 3-year warranty on the sealer. It did not. After setting up their equipment, they explained that cleaning the carpeted stairs would cost nearly as much as the 3 rooms they cleaned. Their truck ran the whole 2+ hours they were there, forcing me to stop painting the garage as I was choking on fumes. The next day I found small stains on the stairs which I cleaned. When I inspected the hardwood floors, the finish was very uneven – glossy in some areas and dull in others -- which means they applied only a single coat of sealer and that the work was done poorly. When I asked for the warranty paperwork, the response was “what warranty?” This property is a rental unit and the new tenants moved in two days after this Zerorez work was completed. Zerorez management offered to inspect the work and add more sealer to the hardwood, but now there was furniture and boxes in the rooms. They refunded part of the overpriced hardwood job and had no explanation for the lie about the sealer warranty. I don’t expect vendors to be perfect, but this was one too many problems for two simple tasks. While we appreciate the partial refund, I will never use this company again and cannot recommend them to anyone."

FAQs for indoor air quality testing projects in Gaithersburg, MD

You should test your home's air quality if you or your family experience health problems like allergies or respiratory issues, as these could be linked to indoor contaminants. Also, consider testing if you're concerned about mold, radon, carbon monoxide, or if you've recently had home construction, demolition, excavation, or remodeling that could have released chemicals into your indoor air.

An indoor air quality test typically takes one to three hours to complete. After the inspection, you'll receive a detailed written report within two to 10 days. The evaluation includes comprehensive air sampling from all designated areas in your home. Your specialist will review the findings with you and provide clear guidance on steps to take if any issues are found, helping ensure your indoor environment meets health and safety standards.

A certified indoor air quality consultant or inspector is the right professional to perform your indoor air test. While some home inspectors have certifications, they often subcontract this specialized work to trained professionals with advanced tools. This expert will thoroughly evaluate air samples from every area in your home and clearly explain the findings to you. Be sure to confirm your tester's credentials before scheduling your service.
