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."

PROTECTING BY INSPECTING! Lead poisoning is no laughing matter. Worldwide, about 143,000 deaths per year result from lead poisoning, and lead paint is the most common perpetrator. You can prevent lead poisoning from taking a toll on you, your family, and your home by having your property inspected. Reliable Lead Inspection Services, LLC has helped countless homeowners across Baltimore, MD and the surrounding counties with their home lead inspections since 2014. The state of Maryland requires that all properties – including apartments, condos, townhouses, lofts, and single-family homes – built before 1978 have a new lead inspection certificate every time the property is rented or sold. Even if you’re not in the market to buy or sell property, it is always a sensible decision to have any home inspected before doing renovations. You never know what could be hiding in those walls! I can provide 24 hour results if needed. Available 7 days a week. MDE Lic #15208 Ask us about our Senior, Police, & military discounts!

"Norman, was very friendly, knowledgeable and informative. He explained everything he was doing through the process. I would highly recommend requesting Norman."

"I had a terrible experience with EXCEPTIONAL RESTORATION. From start to finish, their service was unprofessional, unresponsive, and completely lacking in accountability. Not only did they fail to resolve the issue they were hired for, but their communication was poor and their handling of the situation caused more stress than relief. Despite multiple attempts to get updates and cooperation, they showed no urgency or respect for the damage done to my property. I regret ever trusting them with such an important job and would strongly advise others to look elsewhere. You expect a restoration company to bring peace of mind — instead, this company brought me nothing but frustration and loss of time and money."

Mold & toxic material tests FAQs

Many mold inspection companies offer free phone consultations to determine if there's an actual need for their services. This usually takes a few minutes and typically involves answering a few questions. Unfortunately, companies that offer free mold inspections may be more likely to find a mold problem so they can charge you to fix the problem—even if you don't have any mold issues.

Mold inspections can be quite complex, including visual inspections, sample collection, testing, taking photos and notes, and preparation of reports. To ensure you get the most accurate result, hire a dedicated mold inspection company.

Typically, a basic mold inspection can take about two hours, while a detailed inspection with a suspected mold problem can take as long as six hours. The amount of time it takes to do a mold inspection and mold testing will vary from home to home, so you may want to block off an entire afternoon or morning to accommodate the inspector.

Homeowners can expect to pay anywhere between $1,220 and $3,750 for mold remediation, with an average cost of $2,360. The cost of mold remediation will vary depending on quite a few factors, such as how big the mold problem is, where the mold is located, and the type of mold.
