7 Common Issues Found During Home Inspections in Surrey and Langley

01. Crawl space moisture

A huge number of older Surrey homes were built with crawl spaces rather than full basements, and a lot of them have inadequate ventilation or vapour barriers that have degraded over the decades. Combined with our wet coastal climate, this shows up as damp insulation, musty odours, and sometimes visible mould on floor joists. It’s rarely a deal-breaker, but it’s almost never a surprise the seller mentioned upfront.

This is one of the areas where thermal imaging earns its cost — it can pick up moisture patterns in the floor above a crawl space before they’re visible as staining on the surface material.

02. Aging electrical panels

Homes from the 60s and 70s often still have their original panels — sometimes Federal Pacific Electric panels, which have a documented history of breaker failures. We also still occasionally find knob-and-tube or aluminum branch wiring in homes that haven’t been updated. None of this is automatically dangerous, but it’s exactly the kind of thing insurance companies ask about, and buyers should budget for an electrician’s assessment.

We’ve noticed insurers in BC have become more specific about panel brands and wiring types over the last several years, sometimes requiring an electrical inspection or panel replacement before a policy will be issued at standard rates. It’s worth checking this early in a purchase, not after subject removal, since insurance approval can occasionally hold up financing.

03. Roof coverings past their service life

Asphalt shingle roofs typically last 20-25 years in our climate, and a lot of Langley and Surrey homes built in the late 90s and early 2000s are now sitting right at or past that mark. We check granule loss, curling, and flashing condition around chimneys and vents — the flashing is usually where leaks actually start, not the shingle field itself.

For roofs that are steep, complex, or simply not safe to walk, we bring in drone roof imaging to get close, documented photos of every plane without anyone stepping on aging material.

04. Polybutylene and old poly-B plumbing

Poly-B piping was commonly installed in BC homes through the late 80s and 90s, and it’s known to become brittle and fail at fitting connections over time. It’s not automatically a crisis, but it does affect insurability in some cases, and it’s worth knowing about before you’re the one dealing with a burst line behind drywall. Some insurers now ask directly whether a home has poly-B plumbing, and a small number will decline coverage or require replacement as a condition of the policy.

05. Grading and drainage issues

This one’s simple but shows up constantly: soil or landscaping that slopes toward the foundation instead of away from it. Over years, this pushes water against the foundation wall and is one of the most common contributors to basement or crawl space moisture we see. It’s also one of the cheapest issues on this list to fix — often just a matter of regrading soil and extending downspouts away from the foundation, work that a landscaper can usually complete in a day.

06. Deferred maintenance on decks and balconies

Exterior wood structures take a beating in our climate. Ledger board flashing, post connections, and railing stability are common weak points, especially on decks that are 15+ years old and haven’t been resealed or inspected structurally in a while. Ledger board failure specifically is worth taking seriously — it’s the connection point between the deck and the house, and it’s designed to be a visible, inspectable detail precisely because it’s a known failure point in older deck construction.

07. HVAC systems nearing end of life

Furnaces and heat pumps generally last 15-20 years. We often find systems still functioning but clearly at the tail end of their service life, with signs like rust at the heat exchanger, inconsistent airflow, or an age that lines up with when the home was built and never updated since. A system that’s still working on inspection day isn’t necessarily a passing grade — age and visible wear both factor into how much useful life is realistically left.

How these issues typically get handled in a transaction

In practice, most buyers use inspection findings one of three ways: requesting a price reduction that reflects the cost of addressing the issue, asking the seller to complete the repair before closing, or simply proceeding with full knowledge and budgeting for it themselves down the line. Which path makes sense depends on severity, cost, and how competitive the offer situation is.

When to bring in a specialist beyond the general inspection

A general home inspection is designed to identify these seven patterns and flag them clearly, but it isn’t a substitute for a specialist assessment once something significant is found. An electrician should confirm the scope and cost of any panel replacement. A structural engineer should weigh in on foundation cracking that looks beyond typical cosmetic settling. A roofing contractor can give a firm quote once age or damage suggests replacement rather than repair.

Part of a good inspection report is being clear about which findings need this kind of specialist follow-up versus which are simply worth monitoring.

The takeaway

These seven patterns repeat across Surrey and Langley because the housing stock, climate, and building eras repeat. Knowing what to expect before an inspection — rather than being surprised by a report full of unfamiliar terms — makes the whole process feel less like a pass/fail test and more like what it actually is: a clear picture of what you’re buying.
