If you ask a home inspector what causes the most damage to houses, most will give you the same answer: water. Not fire, not wind. Plain old water, getting in where it shouldn't, slowly, over years.
In the West Kootenays, we have a few extra reasons to pay attention. Many homes are built into hillsides. We get heavy snow followed by fast spring melt. And plenty of properties sit near lakes, creeks and rivers. Here's how to think about water whether you own a home or you're shopping for one.
Start with the ground around the house
The soil around your foundation should slope away from the house, ideally dropping about 15 cm over the first 3 metres. Over time, soil settles and that slope can reverse, sending rain and snowmelt straight toward your basement walls.
Walk around your home during a heavy rain. Where does the water go? If it pools against the foundation, that's your first fix, and often a cheap one.
On hillside lots, which are common in Nelson, Rossland and Trail, water coming down the slope from above can be just as big an issue. Swales, French drains or retaining walls with proper drainage behind them help direct that water around the house rather than into it.
Gutters and downspouts do more than you think
A single rainstorm can drop thousands of litres of water on a typical roof. Gutters collect it. Downspouts decide where it lands.
- Keep gutters clean, especially after the leaves fall.
- Extend downspouts at least 1.5 to 2 metres from the foundation.
- Check that underground downspout connections aren't clogged or broken.
- In snow country, consider heavier-duty gutters and guards that won't tear off under ice.
Perimeter drains and sump pumps
Many homes have a perimeter drain, sometimes called drain tile or weeping tile, that runs around the base of the foundation. It collects groundwater and carries it away, often to a sump pit where a pump sends it outside.
In older homes, these drains may be clay tile that has collapsed or filled with roots. A camera inspection is relatively affordable and can tell you a lot. If you have a sump pump, test it every fall and spring, and consider a battery backup for power outages.
Signs of a water problem
When we tour homes with buyers, we keep an eye out for:
- White, chalky deposits on basement walls (called efflorescence)
- Water stains on drywall, flooring or ceiling tiles
- A musty smell, especially in basements and crawlspaces
- Fresh paint or new drywall in just one corner of a basement
- Rust on the bottom of furnaces or water heaters
- Peeling paint or soft spots on exterior trim
None of these automatically rule a home out. They're clues. A good inspector, and sometimes a moisture meter, will help you understand what's going on and what it'll cost to fix.
Crawlspaces need love too
Many Kootenay homes, particularly older ones, sit over crawlspaces. These spaces can trap moisture and become damp, mouldy and smelly. A proper vapour barrier on the ground, good ventilation or a sealed and conditioned design, and insulation in the right spots all make a big difference.
Water inside the house
It's not only rain and groundwater. Plumbing leaks are a leading cause of insurance claims. A few simple habits help:
- Know where your main water shut-off is.
- Replace washing machine hoses every five years or so, or upgrade to braided steel.
- Look under sinks a few times a year.
- Consider inexpensive leak sensors near the water heater, washer and dishwasher.
- Some insurers offer discounts for automatic water shut-off systems. Ask yours.
Living near the water
Lakefront and riverfront homes are some of the most sought-after properties in the region. If you're buying one, ask about past high-water events, check the property's elevation, and talk to your insurance provider about overland flood coverage before you remove subjects. Some local governments have floodplain bylaws that affect where and how you can build or renovate.
Why buyers and sellers should care
For buyers, water issues are one of the most common reasons deals get renegotiated after an inspection. For sellers, fixing simple drainage problems before listing helps your home show well and inspect clean.
