Older homes have a lot going for them: timeless character, quality craftsmanship, and unique details you just don’t find in new construction. But as any homeowner or buyer knows, charm comes with quirks — and sometimes serious challenges.
At Mose Home Inspection, we specialize in uncovering the stories Montreal’s older homes have to tell. Whether you’re considering a century home in Westmount, a Plateau-Mont-Royal duplex, or you already live in a beloved family property, knowing what to look for is the key to preserving its beauty while avoiding costly surprises.
Here are the seven most common problems in older homes — and how to fix them.
Outdated Electrical Systems ⚡
Many homes built before 1970 weren’t designed for today’s power-hungry lifestyles. Common issues include:
- Knob-and-tube wiring
- Aluminum circuits
- Undersized electrical panels
These can lead to overloaded breakers, limited outlets, and even fire hazards. Many insurers in Montreal won’t cover homes with knob-and-tube wiring unless it’s replaced.
✅ Solution: Hire a licensed electrician to assess your system and upgrade to modern wiring and panels.
2. Aging Plumbing 🚰
Older Montreal homes often contain:
- Lead service lines (pre-1950)
- Galvanized steel pipes (1940s–1960s)
These materials corrode over time, causing low water pressure, discolored water, and leaks.
✅ Replace outdated pipes with copper or PEX. Think of it as giving your home a new set of arteries
3. Foundation & Structural Concerns 🏗️
Cracks in walls, sloping floors, and shifting foundations are common in older houses due to settling or water damage.
✅ Solution: A professional inspection by a foundation specialist or structural engineer will determine whether it’s a minor issue or something requiring urgent repair.
4. Poor Insulation & Energy Inefficiency ❄️🔥
Insulation was often overlooked in older construction. Without upgrades, you may face:
- Drafty winters
- Overheated summers
- High energy bills
✅ Solution: Add modern insulation in attics, walls, and floors, and seal air leaks. This upgrade boosts comfort and efficiency.
5. Roofs at the End of Their Life 🏠
If your roof shingles are more than 20–25 years old, they may be ready to fail. Warning signs include:
- Missing or curled shingles
- Leaks or stains on ceilings
- Damaged flashing
✅ Solution: Schedule a professional roof inspection before water damage causes expensive repairs.
6. Hidden Hazards:
Lead & Asbestos ⚠️
Many older Montreal homes contain:
- Lead paint (pre-1978)
- Asbestos in flooring, insulation, or pipe wrap
These materials are safe if left undisturbed but dangerous during renovations.
✅ Solution: Test before remodeling. Hire certified professionals for safe removal.
