Thermal imaging inspections in Surrey

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. Surrey's mild winters make timing the scan the main thing to plan.

Each house stands for one in ten of Surrey's 139,390 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 Surrey

Surrey gets about 2,851 heating degree-days a year and has a winter design temperature of −6.3°C, according to NRCan's HOT2000 climate data for Pitt Meadows, the closest comparable location in that data set (13 km away). With winters that mild, a 10°C difference isn't guaranteed every day, so book the scan for a cold morning or evening, and ask the advisor to reschedule if the forecast is too warm.

What the camera finds in Surrey houses

Of Surrey's 139,390 houses (single-detached, semi-detached, row houses and duplexes), 5% were built before 1961 and 39% 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 price list; the City of Nanaimo quotes $400–$500 as typical for an existing home. Several B.C. municipalities subsidize evaluations for their residents (see local programs below).

Thermal imaging inspection in Surrey: common questions

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

Pick a cold morning or evening in winter; the camera needs at least a 10°C difference between inside and outside, which isn't guaranteed every winter day in Surrey.

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 Surrey?

Most of the 29 NRCan-licensed organizations serving Surrey bring an infrared camera to an EnerGuide evaluation; confirm when you book.
