"Awesome 🤩 was/is James Nelson, Design Specialist with American Waterworks, out of the Fargo, ND office was absolutely wonderful to work with. (Really this Company has impressed us from the beginning!) always quick to respond and very patient…. There was zero pressure …. no pushy sales tactics at all — just good information, very clear explanations, and genuine care. He took the time to answer questions, explain good options, and made us feel comfortable and valued as people, not just potential customers. From the very beginning, And even now after James has been yet kind and incredibly understanding of our situation. Unfortunately We are not able to move forward with our basement project at this time, and James has showed nothing but grace and respect about that. No doubt that James is a true professional and a rare find these days. We absolutely 💯 Highly, highly recommend James and American Waterworks And Solutions… We thank you!!"

"I had a wonderful experience with MidAmerica Basement Systems & highly recommend them if your having any waterproofing needs. My project: I purchased my home 3.5 years ago & it started getting water in the basement last year after the outside drainage & tiling system put in my previous owners failed miserably. It would literally be full days of pumping water out of multiple locations in my basement. There were issues of moisture even with two dehumidifiers running & subfloors the crew took out & cleaned up after as well. Scheduling: They will schedule a ways out for appointments but only because it's a high demand working system. Others may be able to offer services quicker but there is likely a reason they are not busy. I got several bids in the time I waited for my MidAmerica Basement Systems appointment & encourage you to as well but definitely wait until after your appointment to make a decision. They were not the cheapest but had the best guarantee (100%), best working system, and a few things I've learned in my 20 years of homeownership is if you go cheap & need to redo it your typically spending more than if you did it right the first time & your home is not something to skimp on or take chances. MidAmerica Basement Systems will send you detailed emails as to what you can expect for each appointment. They will mail you a packet of information regarding different systems that work vs fail & throughly explain the dangers & hazards water/moisture in your home will cause. Our basement got so bad from the Derecho the only dry place was in our basement was the shower & my celing developed black mold quickly from the moisture. Not only did they offer a system to waterproof my basement but a whole house dehumidifier & air purifier which would have saved my ceiling if I had earlier. Sales: I had Justin A for sales & he was very thorough in listening to my problems & needs as well as took his time in explaining & showing me how they could fix my issues, how the system works, as well as answering all of my questions with detail & no hurry. He was absolutely great about changes I made in adding work later on (before my appointment) as well. He doesn't make it feel like a sales pitch, is not pushy at all, & really works to get you the most work in your budget (prep & finish work offered), as well as taking his time with you through the entire process. The office crew: The office staff was very polite & helpful. I mostly worked with Desiree S & Kim B who are extremely responsive in working with me. The Crew: My crew consisted of Brandon T, Sam G, & Ethan T who I highly recommend! These young men are the exact type you want on your project! They are polite, respectful, hard working, efficient, trust worthy & have a great work ethic! They not only got the job done in the time allotted but left my basement incredibly clean which I didn't expect. They thoroughly go over the work before & after as well as answer any questions you have along the way & explain in detail any changes if something isn't to plan before just doing something differently. They called before heading to my house as well which I thought was very courteous. I imagine they have a lot of great workers but anyone I know that I send their way, I'll have them ask for these men as the crew on their home. Overall: Overall I give them 5 stars & they earned it all the way. I will say it's winter so not when one typically gets water in their basement so I am unable to review how the system works fairly. I do, however, plan to leave another review after we get some lovely wet Iowa spring weather or melting of our snow mountains to test it out. I don't expect my review to change & feel confident in the upcoming months & years. Thank you MidAmerica Basement Systems!"

Northern Duct Seal seals duct work from the inside by use of computerized tools and equipment. The process takes one day and our technicians will provide pre-seal and post-seal duct leakage reports on the spot. The basic steps to do a duct seal are: 1) Pre-seal Test is done to measure duct leakage, 2) Registers, returns, and air handler coil are blocked off with foam plugs, 3) A UL-tested and approved aerosol is injected into the pressurized duct system, 4) A Post-Seal Test is performed to measure improvements and 5) A complete Report and Certificate are printed to provide the customer with a record of improvement. Duct sealing provides a solution to high energy bills, air flow/air balance issues, uneven temperatures, hot and cold rooms, excessive humidity, musty odors and fume smells from stored paints, solvents, pesticides, and radon gases. Northern Duct Seal will reduce duct leakage by up to 90%, saving customers an average of $600 - $850 a year, with a 2-3 year return investment, depending on variables such as weather, system usage, energy prices, and home design. Northern Duct Seal offers a 10- year warranty on the seals created by our technicians. The sealant itself has been UL tested and approved and is considered non toxic by OSHA. For a demonstration video of the duct sealing process please see the 'Ask This Old House' Video located under the Media tab on this page.

FAQs for radon gas testing projects in Monona, IA

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
