Thermal imaging inspections in Sherwood Park

An infrared camera shows missing insulation, air leaks and damp spots without opening a wall, but only when it's at least 10°C colder outside than inside. Sherwood Park's long heating season gives you months of good scanning weather.

Each house stands for one in ten of Sherwood Park's 34,290 houses (single-detached, semi-detached, row and duplex), drawn by when it was built. The glow shows the usual pattern: older houses tend to be leakier and less insulated. Snowfall scales with heating degree-days.

When to book in Sherwood Park

Sherwood Park gets about 5,435 heating degree-days a year and has a winter design temperature of −30.4°C, according to NRCan's HOT2000 climate data for Elk Island, the closest comparable location in that data set (29 km away). That gives Sherwood Park a long window, roughly late fall to early spring, when the inside-outside difference comfortably exceeds the 10°C an infrared scan needs.

What the camera finds in Sherwood Park houses

Of Sherwood Park's 34,290 houses (single-detached, semi-detached, row houses and duplexes), 4% were built before 1961 and 46% before 1991, according to the 2021 Census. Older houses are where the camera earns its keep: empty or settled wall cavities, gaps at the top of walls, and cold corners where framing bridges the insulation. Run it with the blower door test depressurizing the house and every leak shows up as a cold streak.

What it costs

Most EnerGuide advisors include an infrared scan with the evaluation, but it isn't required, so confirm when you book. There's no provincial rebate or price list; the City of Edmonton's guidance is to expect more than $400 and to get two or three quotes.

NRCan-licensed service organizations serving Sherwood Park

Thermal imaging inspection in Sherwood Park: common questions

When is the best time for a thermal imaging inspection in Sherwood Park?

Late fall through early spring, when it is at least 10°C colder outside than inside. Cold, overcast days with no direct sun on the walls give the clearest images.

Can a thermal camera see through walls?

No. It reads surface temperatures. Missing insulation or an air leak shows up because it changes the temperature of the wall or ceiling surface.

Who does thermal imaging in Sherwood Park?

Most of the 23 NRCan-licensed organizations serving Sherwood Park bring an infrared camera to an EnerGuide evaluation; confirm when you book.
