"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!!"

"Richard Songer was the tech who did the work. He was extremely fast worker, polite and took the time to answer any questions I had. Before he started the work my readings in the basement where in the low 20s. 24 hrs after he finished the work my readings where under 4."

"They were very good at selling the solution, but there was a big gap on the execution of the project, and took multiple iterations to get everything right, I even had to get into the solutioning with the team myself. It is too bad because the technology seems to work fairly well, and that’s why they are getting 3 stars, but I would not use them again."

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 Cresco, 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.
