Top 10 Issues Found in Muskoka Home Inspections (and Why They Matter)

From charming cottages to full-time residences, Muskoka properties are unique—and so are the challenges that come with owning them. Whether it's exposure to the elements, seasonal use, or aging infrastructure, certain issues tend to show up time and again during home inspections in this area. Here are the top 10 problems commonly found during inspections across Muskoka—and why they’re worth paying attention to.

1. Moisture and Water Intrusion

With frequent rain, snow, and freeze-thaw cycles, water damage is one of the most common concerns. Look for signs of leaks in basements, crawl spaces, and around windows and doors. Poor grading and clogged gutters often contribute to the problem.

2. Outdated Electrical Systems

Many older homes and cottages still have outdated wiring—such as knob-and-tube, aluminum wiring or ungrounded outlets—which may not meet current safety standards. Undersized panels or amateur upgrades can also pose a hazard.

3. Roof Wear and Deterioration

Extreme Muskoka winters can be hard on roofs... Especially the winter of 2025! Missing shingles, ice damming damage, and aging materials are common findings. A compromised roof can quickly lead to interior damage if not addressed.

4. Wood-Burning Appliance Issues

Many homes in the region have wood stoves or fireplaces. Improper installation, lack of a WETT inspection, or poor chimney maintenance are frequent red flags.

5. Insufficient or Damaged Insulation

Older homes often lack proper insulation in attics, crawl spaces, or walls. This can lead to heat loss, high energy bills, and moisture problems in the winter months. In attic spaces, this may lead to ice damming during winter causing leaks into indoor spaces.

6. Structural Movement or Settling

Cottages and year-round homes alike can experience foundation settling or shifting, especially if built on rock, clay, or near water. Look for cracks in the foundation, sloping floors, or sticking doors.

7. Outdated Plumbing

Galvanized pipes, DIY repairs, and signs of corrosion or slow drainage are common, especially in seasonal cottages that were converted to year-round use.

8. Pest and Wildlife Intrusion

From mice in the attic to ants in the crawl space, wildlife often finds its way into Muskoka homes. Inspectors frequently spot signs of nesting, droppings, or damage from rodents, bats, or insects.

9. Improper Deck Construction

Decks are a must-have for enjoying the outdoors in Muskoka, but many are improperly built or show signs of rot, loose railings, or unstable footings.

10. Poor Ventilation and Air Quality

Inadequate ventilation in attics, bathrooms, and crawl spaces can lead to moisture buildup, mold, and poor indoor air quality—issues that are especially problematic in tightly sealed homes.

While some of these issues are typical of older or seasonal homes, others can be found in newer builds as well. The good news? A thorough home inspection can catch these problems early, helping you make informed decisions and plan ahead. If you’re buying a home in Muskoka, it’s essential to understand the local conditions—and work with an inspector who does too.
