Thermal Imaging in St. Paul, MN

What thermal imaging adds in St. Paul

An infrared camera reads surface temperature, not the inside of a wall — but the temperature patterns it reveals tell a story the naked eye misses. In a St. Paul winter, a cold streak across a ceiling points to missing insulation; a cold halo around a recessed light points to an attic air bypass feeding attic frost; a cool, irregular shape on a basement wall can indicate active moisture. Used during a home inspection, thermal imaging turns invisible problems into documented findings.

What we scan for

• Missing or settled insulation: cold patches in walls and ceilings, common in older homes with retrofit insulation gaps.
• Air bypasses: leaks at top plates, recessed lights and attic hatches that drive heat loss and ice dams.
• Moisture intrusion: evaporative cooling signatures behind walls and under windows.
• Electrical hot spots: overheating breakers or connections at the panel.
• Radiant heat issues: non-functioning sections in in-floor heating.

How it works during the inspection

The camera is most effective when there is a temperature difference between inside and outside — which Minnesota provides for much of the year. We scan key areas during the walkthrough and capture infrared images of anything notable, then correlate them with moisture readings or visual evidence before reporting. Thermal imaging is a screening tool that points to where a closer look is warranted, not a guarantee that every hidden defect will be found.

Local relevance

St. Paul's cold winters make thermal imaging especially valuable here: the same temperature extremes that cause ice dams and attic frost also make insulation gaps and air leaks light up clearly on infrared. Pairing thermal imaging with a mold inspection is a strong combination when moisture is suspected.
