Why Kamloops Homes Age Faster (and What That Means for Your House This Winter)

Kamloops is one of the most beautiful places in BC, but it’s also one of the harshest places for a home to age gracefully.
If you’ve ever wondered why your siding fades faster…
why your caulking cracks sooner…
or why your windows seem to shift every couple of years…
You’re not imagining it.

Kamloops homes deal with a unique cocktail of geology, climate, and seasonal stress most cities never face.

Let’s break it down in a way every homeowner can understand – and finish with what you absolutely should do before winter hits.

1. Kamloops’ Dry Climate Pulls Moisture Out of Everything

People think “winter damage” means snow.
But here in Kamloops, our biggest enemy is dryness.

• Wood dries → shrinks → cracks
• Caulking dries → loses elasticity → gaps open
• Exterior paint fades faster
• Window and door frames shift
  
  

Kamloops’ climate is closer to a semi-desert than coastal BC.
Your house literally dehydrates.

Why this matters in winter:
When cold hits, shrunken materials stiffen and crack even more.
That’s why rot, drafts, and heat loss explode every winter if gaps weren’t sealed in fall.

2. Our Clay-Rich Soils Move – And So Do Our Homes

Kamloops soil is notorious for:

• Clay pockets
• Expansive soils
• High shrink-swell cycles
  
  

This means the ground expands in wet seasons and contracts in dry ones.

When the ground moves, your home tries to move with it.

Visible signs Kamloops soil is messing with your house:

• Cracks around window corners
• Foundation hairline cracks
• Slanted decks or sinking steps
• Doors sticking
• Uneven floors
  
  

Winter effect:
Cold snaps lock the soil in place, and any existing movement becomes worse – especially around foundations, retaining walls, and older basements.

3. Extreme Temperature Swings Stress Every Building Material

Kamloops regularly jumps from -15°C nights to +5°C daytime.
This freeze-thaw cycle is brutal.

Materials expand, contract, expand again… until they give up.

Common winter casualties:

• Cracked exterior caulking
• Fast paint deterioration
• Window seal failures
• Loose gutters
• Deck boards popping
  
  

If a home isn’t maintained yearly, winter becomes the “stress test” that exposes every weak spot.

4. Sun Exposure in Kamloops Ages Siding and Trim Faster

People underestimate Kamloops UV exposure.
Our summers cook homes.

What the sun does:

• Bleaches siding
• Bakes paint
• Warps trim
• Dries exterior caulking
• Weakens window seals
  
  

By the time winter hits, these sun-damaged materials become brittle – and then the cold finishes the job.

5. Older Kamloops Neighborhoods Weren’t Built for Modern Weather Patterns

Areas like:

• North Shore
• Sahali
• Aberdeen
• Valleyview
• Brock
• Barnhartvale
  
  

A lot of these homes were built 20-40 years ago, when winters were colder but more stable and summers were milder.

Now we have:

• Hotter summers
• More dryness
• More freeze-thaw cycles
• More soil movement
  
  

Older building materials simply weren’t designed for this.

So… What Should Kamloops Homeowners Do This Winter?

Here’s your local-specific checklist – built from what Trusted Reno sees every winter:

• ✔ Check all exterior caulking
  Especially around windows, doors, trim, and siding transitions.

• ✔ Inspect your gutters and downspouts
  Kamloops freeze-thaw cycles clog and crack gutters fast.

• ✔ Look for foundation cracks (even hairline ones)
  Clay soil movement + winter freezing = cracks spreading.

• ✔ Check your attic insulation levels
  Big ROI. Warm air loss is huge in Kamloops.

• ✔ Seal drafts immediately
  Our dry climate + winter cold exaggerates heat loss massively.
  
  
  
• ✔ Address any wood rot BEFORE cold weather hits
  Rot accelerates in winter when moisture gets trapped.
