"Working with Damian was the easiest part of restoring my fixer upper! He's incredibly easy to work with, transparent and honest, and does great work for great prices. He managed to get started right away for me since the mold in my house was indeed toxic, and I couldn't be more grateful for the positivity he brought to what has been a very stressful situation for me. I couldn't recommend him more!"

"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 performed the job in a much more efficient manner than I expected. We had mold in our walls and I thought we’d have to replace our bathroom vanity. He went above and beyond, was knowledgeable, insightful, friendly, and responsive. He provides recommendations about other aspects of the house in a tactful way that I find incredibly valuable as a first time homeowner. Highly recommend!"

Mold Testing and Remediation FAQs, answered by experts

Visible growth, musty odors, and water damage are common indicators.

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.

While the resistance of lime to mold is a hotly contested topic of debate, it is true that because it allows porous materials to breathe, it avoids trapping moisture close to the structure of a building. This breathability makes it less susceptible to mold than paint because it gathers less moisture.

The easiest way to know if it’s a leak or evaporation that’s causing low water levels in your pool is by conducting the bucket test. However, you can also monitor the chemicals in your pool for signs of imbalances or conduct a visual inspection of the areas around your pool in search of excessive moisture or cracks.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.
