We are a family owned and operated business. We are an independent 3rd party mold testing and mold inspection company. Mold remediation protocol written by the IICRC (Institute of Inspection, Cleaning and Restoration Certification) states that remediation companies should not do their own testing and testing companies should not do remediation, it is a conflict of interest. Not all mold projects needs to be professionally remediated. Our goal is to not only let you know if you do have excessive mold but how did you get it and how can you prevent it in the future by providing honest and outstanding service through dedication, hard work, attention to detail, integrity, and always focusing on our clients' best interest at hand. We know that the secret to our success has and will continue to be our satisfied clients. We will go anywhere in Maryland. Some of our clients include Governor Hogan, The Maryland State General Assembly, Property mangement companies, Insurance companies etc.

"They were wonderful to work with and were prompt in coming out."

Water Damage DMV is a full service water damage restoration company. Our staff is dedicated and I.I.C.R.C certified to help mitigate water damage. All our damage restoration staff are trained to use the most modern equipment and techniques to return properties to pre-loss condition following fire or water damage. Our team is available 24/7 to handle damage restoration projects large and small. We will immediately take action by coordinating with your insurance carrier, securing the structure, performing damage removal.

"I sent my initial inquiry e-mail at 6:24AM, and Carlos wrote back at 6:52AM asking if he could come by that morning between 8 and 9AM. After having three other companies quote it, I selected Water Damage DMV based both on the cost of the estimate, his promptness and communication, and the clarity in answering questions I had. When Carlos arrived to do the work, he went right to it. He worked quickly and kept me informed about what he was finding and how it was going. When he was done with that, he put in humidifiers at first. The next day, he came with help to apply the mold-prevention treatment before adding fans to aid in drying. He checked in daily either in person or by text until it was time to remove them, at which point he came and did so. I was very happy to work with Carlos and Water Damage DMV. While I hope to never need their services again, if I happen to be that unlucky, I know who I will be calling."

Biohazard Remediation questions, answered by experts

Refinishing typically takes 1-3 days, allowing for adequate drying times between coatings to ensure a durable finish.

The costs depend on the appliance's size, type, and the complexity of the finish desired, ranging from $200 to $750 per appliance.

Kitchens often see refrigerators, ovens, and dishwashers commonly refinished due to high visibility and frequent use impacts.

If you have decided that hiring a professional to refinish your floors will be faster and more satisfactory, you can expect to pay between $1,000 and $2,500. To get a better idea of what your hardwood refinishing project will cost with a professional, multiply the project’s square footage by the average price of $4 per square foot.

The process involves prepping surfaces, applying primer, and finishing with a coating that restores appearance and durability and provides an updated look.
