"They installed a Radon Mitigation system in a house I was selling. They had the best price, the experience I wanted, and were able to install a few days after I called. Technician was very nice and efficient in getting it installed. Good warranty too. I had my system installed in an encapsulated crawl space."

"RADON SYSTEM WAS NOT WORKING. (Installed by another company years ago). The phone contact was pleasant and efficient. The Technician came on the agreed day and the agreed time: he explained what was wrong, explained the options, then repaired the system so it is working better than it did when first installed."

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 abatement projects in Thor, IA

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
