"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."

"I was impressed with the extent of knowledge that the tech exhibited upon his first visit. He was concerned and as interested in knowing the source of my problem as I was. He had a very quick understanding of what my needs were. I believe that he had the most reasonable explanation for the cause of the mold and more importantly, his company was going to handle it in the manner that I thought was safest in every way for me and my household. His explanation seemed to stem from experience and I was confident that my health was protected while doing this mold removal process. I appreciated not being scared into doing this removal."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

"We cannot recommend this company highly enough! Dealing with water damage is incredibly stressful, but from our very first conversation, ServPro employees showed sincere empathy for our situation and immediately put us at ease. They were always friendly and highly responsive to every message and question we had along the way. We were on a tight timeline with company arriving for Memorial Day weekend, and ServPro treated our deadline with a true sense of urgency. They stayed completely on top of the schedule and showed incredible flexibility. Throughout the entire process, they instilled total confidence. We felt completely reassured that they were doing everything in their power to get the job done right and on schedule. If you want someone who pairs expert work with elite communication and genuine care, I'd highly recommend ServPro!"

"The cleaners did an excellent job in cleaning the carpet and attempting to remove all darkened areas in the carpeting. There were a few areas that they were unable to remove completely, but it appeared that those areas wouldn't come clean anyway. They did forget to clean the storage area at the entrance of the apartment, but this was not an issue as that room is being re carpeted."

Mold Testing and Remediation questions, answered by experts

Be cautious of vague or unusually low quotes, pressure for full payment upfront, or companies that combine testing and remediation without independent verification. Watch for contractors who overlook moisture sources, promise to “eliminate” mold entirely, or avoid providing proof of insurance. Ensure they understand Appleton’s building codes and are familiar with issues like basement seepage common in local homes.

Helpful?

Appleton’s humid summers, spring thaw, and frequent rain can increase moisture levels, making basements and attics especially prone to mold. Remediation is most effective from late spring to early fall when conditions favor drying and moisture control. Winter projects may require extra ventilation and heating, so plan accordingly to address the unique climate challenges that affect local mold growth and air quality.

Helpful?

When hiring for mold testing and remediation in Appleton, look for pros with experience handling local home styles, especially older homes with limestone basements or crawl spaces. Ensure they carry proper insurance, provide detailed air quality reports, and keep testing separate from remediation. Ask for documentation specific to Appleton’s common moisture issues and request before-and-after photos showing work in similar local properties.

Helpful?

In Appleton, combining mold remediation with upgrades such as basement waterproofing, improved insulation, or ventilation system updates can boost air quality and moisture control. Coordinating these projects, especially in spring or summer, helps address underlying issues unique to local homes and can streamline scheduling. This approach often results in longer-lasting protection against mold and better overall home health.

Helpful?

In Appleton, hidden costs may arise from uncovering mold behind plaster walls, needing structural repairs, or cleaning HVAC systems affected by spores. Additional expenses can include fixing sump pumps, addressing foundation cracks, or arranging temporary accommodations if large areas are impacted. Post-remediation air quality testing and extended project timelines, especially during winter, are also common surprises in local projects.
