"Henry came to our house. He was very knowledgeable about mold and what to look for. He answered all my questions and was very helpful. Peter who called me with the results was very nice and answered my questions. He even called back the next day when he noticed that an email he sent me didn t go through. They gave me a lot of information to help me continue my search to get rid of my mold and poor air flow."

"I can't say enough how wonderful Damian is and all the help he provided me. He is very patient and has a heart of gold. He provided a demo for me to use while I was undergoing water damage. He explained how the air testing works and his air quality machine is amazing. He went above and beyond to accommodate me, providing his vendors to help assist me in my remodeling process. He has just been amazing in this whole process. There simply isn't enough good people who care for their customers like he does. There needs to be more Damian's around. Thank you so much for your guidance and support you provided me. I am so grateful that Angi provided me your business. You are simply a great person who shows compassion in all you do."

"We contacted this company based on the positive reviews. It seems as though that there aren't many companies who want to touch this type of work (so to speak). Or, if they do they are expensive. DJK wasn't much of an exception. They did respond rather quickly when I had first contacted them. They came out and inspected the suspected mold problem area in our bedroom. So finally about 3 weeks later, $1,330.00 and 2 hours of work AND for a 2' x 2' square hole cut out in our bedroom wall. And, they had sprayed a potent biocide chemical that hopefully killed our mold problem! They don't do any mold air quality testing at all. Hence, a lab is involved. DJK will come out in advance and use a moisture meter that is supposed to detect where the moisture sits. Then they zero in on the behind the walled suspect area. That problem was caused by another painting contractor who supposedly did caulk around our windows! Apparently not. Otherwise water wouldn't have seeped in and caused this issue. Oh well, another review and problem for another day. We think it's now gone. And we'll be happier for that part. They charge extra to repair the plaster wall with a drywall (NOT plaster). You'll have to hire someone else to do plaster repair if that is what you want. Don't forget about replacing the possibly contaminated wall insulation that they may take out and dispose of. Then figure either priming and painting it yourself after the plaster has cured. Or, hiring yet another darned contractor. In short, I think DJK does the job ok, but they ain't cheap. We will see."

Customers say: Quality work

"Keith Elliot helped with our plumbing issue that happened. Even though Choice warranty denied our claim he was able to come out and help with the fix for out of pocket on our side. He is extremely knowledgeable and knows how to work with old plumbing for what to replace and what can be done with repairing the existing ones. Definitely recommend him."

Mold Testing and Remediation FAQs, answered by experts

Yes, limewash is free of volatile organic compounds (VOCs). Made of lime and water, it is eco-friendly, breathable, and toxin-free. Most synthetic paints have low to high levels of VOCs, which causes their irritating odor, which can have adverse and long-term effects on your health. Conversely, limewash consists of crushed limestone, which undergoes burning, mixing, and aging before being diluted with water—natural pigments add coloration.

Dehumidifiers do not directly remove mold or spores from the air. However, by lowering the room’s humidity, spores are less likely to flourish when landing on surfaces.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Powdery mildew is exactly like it sounds—a widespread mold that looks like baking soda or talcum powder. It’s usually seen on plants and spread in warm climates, which is why many people first discover this issue in their home greenhouse. Over time, plants have become resistant, but if you see it spreading, baking soda and water can eliminate many cases. Otherwise, consider neem oil or fungicide. 

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.
