When you have mold, making the correct decisions right away is critical. Whether it is mold in your home, school, place of work, or apartment there are many factors to consider. Are you going to be involved in a mold lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need post mold remediation testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It is important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages and property damages require different environmental tests to prove your case in court. Tests that a common, or inexperienced, mold inspector would not typically use or know to use.

"When I first called mold test company they was friendly and very concerned about my issue a inspector came out did the air testing looked very professional and acted very professional I'll get a call a few days later saying that the test went wrong and that they was going to mail me a asbestos kit out so I can do the testing and send it back to them they wouldn't come back out to retest that's wasn't fair to me that is not what I paid for $469 for them check to come out to make sure that my air is clean so I can have my carpets laid down by empire now I'm still waiting and they asking me to do the testing and that is very unfair to me that is not the services I pay for I did not make that mistake the company did that and that wasn't my problem I'm very disappointed with this company they haven't render the services that I paid for I shouldn't have to do no testing they should have came back out and retested and it would have been no problem so far as that part that was the problem I have with this company they made a mistake and they want to make it inconvenient for me because they didn't want to send somebody back out. And if they talk to me I'm probably wouldn't conversated them for the time but they talk to like it was fault"

"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Mold Testing and Remediation questions, answered by experts

When hiring in Harrisburg, choose professionals familiar with the area’s historic homes, frequent basement dampness, and local permit requirements. Look for strong references from nearby neighborhoods and ensure they carry proper insurance. Ask about their experience with moisture control and indoor air quality improvements. Be cautious of contractors who use high-pressure tactics, request full payment upfront, or provide unusually low estimates.

Helpful?

In Harrisburg, a frequent mistake is ignoring persistent moisture in older stone foundations or skipping professional mold testing after basement flooding. Homeowners sometimes overlook attic ventilation or hidden mold behind paneling. Failing to repair minor roof leaks promptly, starting remediation during peak humidity, or neglecting to document work for future property records can also lead to recurring mold and indoor air quality issues.

Helpful?

After mold testing and remediation in Harrisburg, prioritize moisture control by keeping indoor humidity between 30-50%, especially during muggy summers. Use dehumidifiers in basements, check crawl spaces for dampness each season, and replace HVAC filters every two to three months. Regularly inspect window wells and sump pumps, and ensure kitchen and bathroom exhaust fans vent outdoors to maintain healthy indoor air quality.

Helpful?

Harrisburg’s location near the Susquehanna River increases flood risk, especially in neighborhoods with older homes or poor drainage. The city’s rolling terrain can cause water to collect in basements after heavy rain. If your property is in a historic district, you may need extra approvals for remediation work. Seasonal humidity swings and aging infrastructure also impact moisture control and project timing.

Helpful?

In Harrisburg, combining mold testing and remediation with upgrades like basement waterproofing, sump pump installation, or gutter repairs can streamline moisture control and improve indoor air quality. Coordinating these projects reduces disruption and helps address underlying water issues in one effort. Scheduling work before the rainy spring season or alongside HVAC upgrades can further protect your home and enhance long-term comfort.
