Indoor Environmental Management

I had a great experience with Indoor Environmental Management from start to finish. They completed a full crawl space encapsulation for my home, and the quality of the work truly exceeded my expectations. The crew was professional, knowledgeable, and respectful of my home throughout the entire process.

What really stood out to me was my experience dealing directly with the owner, Mr. John Hassler Sr. He was honest, responsive, and took the time to clearly explain every step of the project. It’s rare these days to work with a company where you feel that level of personal care, integrity, and pride in their work.

I feel confident knowing the job was done right. I highly recommend Indoor Environmental Management to anyone considering crawl space work or indoor environmental solutions—you’ll be in excellent hands.

We have originally reached out to Indoor Environmental Management just to get a second opinion on encapsulation of our mobile home. They have offered a free inspection to gain knowledge about the circumstances and work involved and to be able to provide a cost estimate. Jason was promptly on time and did a thorough assessment. He explained the procedure of encapsulation and suggestions were so clear, that it was very easy to understand. What impressed us most is that at no time did we feel pushed or sold a service that we might not need.
Once we received the proposal the work was scheduled within just a few days.
Again, the work crew came promptly on time (so rare in the greater Tallahassee area) and went straight to work. The job was done very efficient, and we were so impressed with the outcome. Very professional, clean work, and we now have peace of mind.
To sum this up, the receipt of the invoice and the process of payment was handled with such customer centered care, we were given several options and received the payment confirmation in the blink of an eye.
This company stands out with exceptional service from the business owner John to Jason, providing his expertise and answering all questions, to the crew doing the work AND demonstrating excellent customer service, to Kara who handled the invoice and payment part.
We can only highly recommend this company, so folks in the greater Tallahassee area, look no further - you found the right company here: Indoor Environmental Management.

I cannot say enough good things about Indoor Environmental Management. From start to finish, this was one of the best service experiences I’ve had with any home-related company.
From the very first phone call, John was incredibly prompt, professional, and easy to communicate with. He took the time to listen carefully to my concerns, explained the process clearly, and never once made me feel rushed or dismissed. His communication throughout the entire process was outstanding — responsive, transparent, and reassuring at every step.
Most importantly, he completely solved a persistent mildew problem that had been causing stress and concern. What stood out was how thorough and knowledgeable he were. He didn’t just treat the surface issue; he identified the underlying cause and addressed it properly, which gave me real confidence that the problem was handled the right way, not just temporarily covered up.
The team showed up on time, worked efficiently, and treated my home with care and respect. It was clear they take pride in their work and genuinely care about delivering high-quality results. Their attention to detail and professionalism were exceptional, and the results speak for themselves — the difference was noticeable immediately.
If you’re dealing with air quality issues, mildew, or any environmental concerns in your home, I would recommend Indoor Environmental Management without hesitation. They combine expertise, integrity, prompt service, and excellent communication — a rare and incredibly valuable combination. I am extremely grateful for their help and would absolutely use them again in the future.
Highly recommend!

The team at Indoor Environmental Management is second to none full stop. The team is warm, professional, and meticulous. John and his team identified a concerning issue in my home, explained it clearly, and walked me through several options to resolve it. They then fixed the problem thoroughly and ensured it wouldn’t return. 10 out of 10, highly recommend.

We had an excellent experience with Indoor Environmental Management in Tallahassee. They were prompt, professional, and extremely thorough in helping us identify the cause of a musty smell in our home. We had initially received a recommendation from another company that suggested extraordinary costly measures would be necessary just to determine the cause, so we called Indoor Environmental Management for a second opinion.

Their team conducted a detailed assessment and provided clear, science-based findings that left no room for doubt. Their approach gave us confidence and peace of mind, and we are so grateful for their honesty and expertise. We highly recommend their services to anyone needing reliable indoor environmental testing.
