Victoria’s real estate market is filled with charm — character homes, heritage properties, and renovation opportunities everywhere you look. For buyers dreaming of restoring a classic Victoria home, a fixer-upper can be a smart investment. But before you dive into your renovation project, there are a few costly surprises you’ll want to watch for.
In this blog, we’ll break down three common building materials found in older Victoria homes that can impact your renovation budget, insurance, and even your health: asbestos, Poly-B plumbing, and knob-and-tube wiring.
Here’s what every buyer and renovator should know before purchasing an older home in Greater Victoria.
1. Asbestos — The Hidden Hazard in Older Homes
If you’re looking at homes built before the mid-1990s, there’s a good chance asbestos could be hiding somewhere in the property.
Asbestos is a naturally occurring fibrous mineral that was widely used in construction materials for its heat resistance and insulating properties from the 1930s through the mid-1990s. It was so common, in fact, that even classic films like The Wizard of Oz used asbestos for snow effects on set.
Where Asbestos Might Be Found
You’ll often find asbestos in:
- Drywall joint compound
- Vermiculite insulation (attics and walls)
- Floor and ceiling tiles
- Heating duct insulation
- Exterior shingles and siding
The danger of asbestos arises when it becomes airborne — for example, during demolition or sanding — as long-term exposure can cause mesothelioma, an aggressive form of lung cancer.
What to Do if a Home Has Asbestos
If asbestos is suspected, don’t panic. The material itself isn’t dangerous if it’s intact and sealed. A professional can take samples for testing, and if confirmed, you can either encapsulate (seal it in place) or have it safely removed by a licensed abatement contractor.
Keep in mind that asbestos removal can be expensive — often thousands of dollars depending on the size of the affected area — so it’s wise to factor that into your renovation budget.
Pro tip: Always have a professional home inspection and, if needed, an asbestos test before removing walls, flooring, or insulation in any home built before 1995.
2. Poly-B Plumbing — The Leaky Legacy of the 80s and 90s
Next up is Poly-B (Polybutylene) — a flexible plastic piping used extensively from the late 1970s until the early 2000s. It was marketed as a cost-effective and easy-to-install alternative to copper.
Unfortunately, it turned out that Poly-B deteriorates over time when exposed to chlorine and other oxidants found in municipal water supplies. This chemical reaction can cause the pipes to become brittle and leak, especially at the fittings.
How to Identify Poly-B
Poly-B is easy to spot — it’s usually grey, bluish, or purple plastic piping. Most Victoria home inspectors will flag it immediately.
The Risks
Homes with Poly-B may face insurance complications, as many insurance companies hesitate to cover properties with this type of plumbing due to its history of leaks. The most vulnerable points are where the pipes connect — if they have plastic fittings, the risk of failure is higher. Homes with copper fittings are less problematic but still considered a concern.
What Buyers and Renovators Should Do
If you’re planning a renovation or purchasing a property with Poly-B, it’s worth budgeting to replace it with modern PEX or PVC plumbing. The cost can range from $5,000 to $15,000+, depending on the size of the home.
In the meantime, some insurers will cover the home if you install shut-off valves or provide proof of recent upgrades, but it’s always best to check with your provider.
Pro tip: During your inspection period, ask your home inspector to specifically check for Poly-B and document it in their report — this gives you leverage during negotiations or can help you plan future upgrades.
3. Knob and Tube Wiring — A Vintage Electrical System with Modern Risks
If you’re looking at a true character home — especially those built before the 1950s — you may come across knob-and-tube (K&T) wiring. This system was the standard electrical method from the 1880s through the 1940s.
How It Works
Ceramic knobs were used to anchor wires, while ceramic tubes protected them as they passed through wooden framing. The wires themselves were insulated with a rubberized cloth — a material that has long since degraded in most homes.
Why It’s a Concern
While innovative in its time, K&T wiring lacks a ground wire, which is essential for preventing electrical shock and fire hazards in modern systems. Over time, the insulation becomes brittle, increasing the risk of short circuits and overheating.
What You Can Do
Most homes in Victoria that still have K&T wiring have already had partial replacements — but even small sections of active K&T can raise red flags for insurance companies and lenders.
If you find K&T in a home you’re buying, hire a qualified electrician to assess the system and quote a full rewiring. The cost can vary widely depending on the size and accessibility of the home, typically starting around $8,000 to $20,000+ for a complete update.
In some rare cases — particularly with designated heritage homes — the City of Victoria may offer grants or tax incentives to help offset the cost of maintaining character while upgrading safety systems.
Pro tip: Never attempt to DIY electrical work in a home with knob-and-tube wiring. Always use a certified professional.
Why These Issues Matter for Buyers and Renovators
Older homes in Victoria often carry a mix of historical beauty and hidden maintenance challenges. Understanding these potential issues before you buy can save you thousands of dollars and countless headaches during your renovation.
For buyers, a thorough home inspection is your best defense. For renovators, knowing where these materials might exist helps you plan timelines and budgets realistically — especially if you need professional remediation.
And for investors, these issues aren’t necessarily deal-breakers — they’re opportunities. Properties with Poly-B plumbing or outdated wiring often sell for less, allowing you to factor upgrade costs into your purchase strategy.

Buying a home with renovation potential in Victoria can be incredibly rewarding — especially when you know what to look for. By understanding the signs of asbestos, Poly-B plumbing, and knob-and-tube wiring, you can make informed decisions and protect your investment.
