"Mike did a very through job inspecting the house and then went over everything carefully with me. He spent a lot of time and even came back another day because initally he could not access the attic to determine insulation. Again he spent a lot of time and effort making sure I understood his remarks and concerns. He wrote a very detailed inspection report with many photos showing why he made the comments he did in the report. Because of his report and the sellers unwillingness to pay the entire amoutn for the problem areas I had to cancel my purchase agreement. Sure I was out the cost of the inspection but in the long run Mike no doubt saved me a great deal of money and huge headache and heartache!"

"Horrible The experience was awful with this people. I didn't know this company at all, my insurance company send me a list of 5 general contractors to take care of my house, so I pick J Benson because they were close to my house and I want it to keep the contractor local and close. So I went with them. They send an estimator like one day after the damage of the house, I signed the paperwork and two days later they send a different person because the first guy had previews commitments, so that was the first red flag. The second estimator took a lot more pics of the house and did he's first estimate, he submitted to the adjuster and it passed just fine. But then it took them almost one whole month before any one started to work in my house, not a single nail was removed or anything. Then I found out that numerous contractors were going in and out of my house with out me knowing it. Finally the work started and the job "foreman" got involved, this guy was even worst, he only called and picked up the phone when he need it something for me other ways good luck trying to get a hold of him. This guy should be FIRED and never allowed to work on the field again. One day I called him and he's answer was "what do you need, I am kind of busy right now" Awesome. Then I asked for an estimate to build a brand new bathroom in the basement. The estimator give me he's quote and we agreed on the price, so they started the project about one month after the paperwork was signed. About 80% of the work was done when I found out that the estimator "FORGOT" to add the toilet and the tub on the estimate!!!!!! How can any one do that????? So I had to came up with that $$$ And then there was the communication with office personnel. Since day one right after I signed the paperwork I offer to give them money, the estimator said "some one from the office will contact you" NO one ever did, weeks went by with out a single person contacting me about money. Finally some one did and every time we communicated there was a mistake with the numbers, every time there was an "I am sorry I forgot" Unreal this people. A couple of weeks before the project was done and I was super upset with every one involved at this point I requested a supervisor. He reached out to me and we meet at my house. He right away start asking me for money, I pretty much lost my cool there and I went off about all of the issues I was having with he's people. He's answer " I am sorry I wasn't aware of the issues" This shows how unprofessional this company is I can't believe how this people are in business not only in the twin cities but in southern Minnesota."

FAQs for mold & toxic material test projects in Duluth, MN

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
