"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."

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.

Radon Detection and Reduction questions, answered by experts

Costs depend on property size, test types, and additional services like mold sampling.

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional. 

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

You should have a professional test for radon every two to five years. A good rule of thumb is to get testing done every five years if you’ve never had an issue before and every two years if you have. You may also want to schedule testing if you notice symptoms of radon exposure or if you do intermittent DIY radon testing and notice changes in your levels between tests. If you have an active radon monitor, you can schedule testing if you notice levels increasing over time.

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.
