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.

Mold & toxic material tests FAQs

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
