"This was a great experience. I am very happy to have found Moldgone LLC. Everything was smooth from start to finish. The inspection was fast and simple, I received the quote quickly and the price could not be beat. They set the appointment and all communication in between were timely and informative. Jason & Curtis were my techs. They were friendly, fast, thorough, and did a wonderful job cleaning the model and repairing the area. I hope I never have mold again, but if I do, I will call them! Wonderful service and experience!"

"Timely, efficient, response. Identified a minor mold issue and applied appropriate treatment. Poor quality filters on equipment left a film of fine dust everywhere near a vent. Recommend upgrading vacuum filters to finer screen."

"Excellent. Bruce is extremely honest and professional. I called Bruce after an exterminator warned me that he saw mold in my basement. Bruce came the next day, arrived exactly on time and upon visual inspection, told me that I did not have a mold issue. He could have easily set up treatment and I would have paid as I was afraid for the health of my family but Bruce is about as honest as they come. Jason"

"Dealing with mold in your home is stressful, but working with K & E was the absolute best decision we could have made. From the minute they walked in, Dan put us completely at ease. They didn't just clear out the mold they took the time to explain the whole process, kept everything impeccably clean, and treated our home with real care. You can tell they actually care about the people they?re helping. I can finally breathe easy in my home again. Highly, highly recommend!""

"Very well. Will serviced the house. He suspected there could be mold in the ducts, because there wasn't any in the furnace itself. I had burning sensations in my eyes and throat and that usually is generated by mold. The burning continues, so I'm not sure there was a mold issue, but I'm glad I had the service done just in case there was. Will is very professional. Explained everything that he was going to do. He left the house in the same condition as when he arrived. Also, he was quick to say that if I had any problems in the future, he would be glad to come back."

"This is not a mold remediation company. When you hire this company, you are simply getting a mold test. Be specific when you explain your problem and what you are looking to get done. The mold technician was in and out in 20 minutes. He took an air sample and one swab, that s it. For the price of $299. Once you get the results of your mold test, they refer you to a company that is in the business of selling mold remediation products. Originally as much as $1600 for mold bombs, sprays and commercial graded air scrubber. I negotiated down to $1195. Then settled on only what I needed. Know what you want, do your homework before buying products you do not need."

Customers say: Quick response

"The mold inspector was very knowledgeable regarding the mold inspection process. He took samples of mold area for lab evaluation and air quality samples to check for mold in the air around the affected area. I was impressed with the thorough process used to check for mold. Mr Riddick the owner checked the air outside that was in close proximity to affected area. He answered all the questions and provided a date for the results of the inspection. Mr Riddick did an outstanding job and would highly recommend him for his service."

Mold Testing and Remediation FAQs, answered by experts

If you notice persistent musty odors, visible mold returning on walls or ceilings, or humidity levels consistently above 60%, previous remediation in Frederick may have been incomplete. Watch for water stains, peeling paint, or condensation on windows, especially after heavy rain. Ongoing allergy symptoms or failed air quality tests are also strong indicators that further mold inspection and remediation are needed.

Helpful?

For mold testing and remediation in Frederick, keep a digital hygrometer for monitoring humidity, a moisture meter for detecting hidden dampness, and a HEPA air purifier for ongoing air quality. Stock up on N95 or P100 masks, disposable gloves, and antimicrobial cleaning solutions. A UV flashlight helps spot hidden mold, while a camera is useful for documenting problem areas, especially in basements or attics.

Helpful?

In Frederick, unexpected costs during mold remediation often include fees for additional mold inspection, HVAC duct cleaning, and repairs to plaster or wood framing common in historic homes. Extended equipment rentals may be needed during rainy seasons. Homeowners also encounter expenses for storing belongings, addressing foundation drainage, or temporary relocation if extensive remediation is required due to local climate conditions.

Helpful?

In Frederick, mold testing typically takes two to four days, including inspection and lab analysis. Remediation for small areas can be completed in one to three days, while larger or whole-house projects may require up to two weeks, especially in older homes. Weather delays, permit processing, and insurance approvals can extend the timeline, particularly during Frederick’s wetter months.

Helpful?

After mold remediation in Frederick, schedule post-remediation air quality testing within 48 hours to confirm success. Monitor indoor humidity, especially during humid summers, and inspect basements or crawl spaces for moisture. Review all remediation documentation and keep detailed records for insurance. Consider quarterly mold inspections, as Frederick’s older homes and river proximity can make them more susceptible to recurring mold issues.
