"Winter Damage Warning Signs Every Homeowner Must Check"
Introduction
We're deep into another harsh Georgian winter, and your house has sustained significant damage. Between the heavy snow, ice storms, and constant freeze-thaw cycles, January is when winter damage begins to manifest itself—often in ways that may cost you thousands if you wait until spring to remedy them.
What is the good news? Most winter damage provides warning indications. Catch them early, and you can keep minor issues from becoming severe emergencies. This weekend, grab a flashlight and spend 30 minutes checking these critical areas of your home.
1. Ice Dams on Your Roof (Check Immediately)
What to Look For:
Ice dams form when heat escapes through your roof, melts snow, and that water refreezes at the eaves. Look for icicles hanging from the edges of your roof, which can indicate that water is pooling and freezing. Additionally, check for any signs of water damage on your ceilings or walls, as these signs could suggest that the ice dam is causing leaks within your home.
Icicles hanging from your gutters (especially large ones)
Ice buildup at the roof edge (thick ice ridge)
Water stains on your ceiling or walls near the roofline
Sagging gutters from ice weight
Why This Matters:
Ice dams don’t just look dangerous—they ARE dangerous. Water backs up underneath your shingles, leaks into your walls, damages your insulation, causes mould, and ruins your ceiling. I’ve seen ice dams cause $5,000–15,000 in damage to Georgina homes.
What to Do:
Immediate action:
Safely remove snow from roof edges with a roof rake (from the ground).
Never chip away ice—you’ll damage shingles.
If you notice any water stains indoors, please contact a professional right away.
Long-term fix:
Improve attic insulation and ventilation
Seal air leaks in your attic
Consider professional ice dam prevention before next winter.
When to call a pro: If you have active leaking, extensive ice buildup, or see interior water damage. This guidance emphasizes the importance of addressing both immediate issues and long-term solutions to prevent further damage. Consulting a professional is crucial when facing significant problems like leaks or extensive ice, as they can provide expert assessment and remediation.

2. Foundation Cracks (Freeze-Thaw Damage)
What to Look For:
Walk around your foundation—inside and outside—looking for cracks that may indicate freeze-thaw damage. Pay attention to any gaps wider than a quarter inch, as these can allow moisture to seep in and cause further deterioration if left unaddressed. Regular inspections can help you catch these issues early and prevent costly repairs down the line.
New cracks (or existing cracks that got bigger)
Horizontal cracks are more serious than vertical ones.
Stair-step cracks in brick or block foundations
Water seeping through basement walls
Bowing or bulging walls
Why This Matters:
Georgina’s freeze-thaw cycles are brutal on foundations. Water gets into small cracks, freezes, expands, and makes them bigger. What begins as a minor crack in January can escalate into a significant structural issue by spring.
What to Do:
Document everything:
Take photos of all cracks with a ruler for scale
Mark the ends with pencil and date them.
Check monthly to see if they’re growing
Small cracks (less than 1/4 inch):
Monitor through the winter.
Seal it in spring when the weather warms.
Large or growing cracks:
Call a foundation specialist NOW
Don’t wait—spring rains will worsen it.
When to call a pro: Any horizontal crack, cracks wider than 1/4 inch, or cracks with water seeping through require immediate professional assessment. These types of cracks can indicate serious structural issues that may compromise the integrity of your foundation. Addressing them promptly can prevent further damage and costly repairs down the line.

3. Interior Paint Bubbling or Peeling (Moisture Problems)
What to Look For:
Check these high-risk areas: around windows and doors, as well as in corners and near plumbing fixtures. If you notice bubbles or peeling paint, it may indicate underlying moisture issues that need to be addressed promptly to prevent further damage to your walls and structure.
Pay particular attention to the exterior walls facing north.
Bathroom ceilings and walls.
The kitchen walls should be near the exterior.
Basement walls.
Particularly, pay attention to the areas surrounding the windows.
Look for:
Paint bubbling or blistering.
Peeling paint.
The paint may exhibit discoloration or water stains.
Musty odours.
Why This Matters:
Paint doesn’t just bubble for no reason. It’s telling you there’s a moisture problem—condensation, a leak, poor ventilation, or inadequate insulation. You ignore it, and you’re looking at mould, rot, and expensive structural repairs.
What to Do:
For small areas:
Scrape off loose paint.
Let the area dry completely.
Identify and fix the moisture source.
Reprime and repaint in the spring.
For large areas or recurring problems:
This indicates a bigger issue (roof leak, plumbing leak, or ventilation problem).
Don’t just repaint over it.
Repair the source of moisture first.
When to call a pro: If you can’t identify the moisture source, if the problem covers large areas, or if you see mould growth, call for a professional inspection. Addressing the moisture issue is crucial, as simply repainting can lead to further damage and recurring problems. A professional can provide the expertise needed to identify hidden sources of moisture and ensure a lasting solution.

5. Window and Door Drafts (Seal Damage)
What to Look For:
On a cold, windy day: You may notice drafts seeping through gaps around windows and doors. Check for any visible cracks or damaged weatherstripping that could be allowing cold air to enter your home.
Feel around windows and doors for cold air.
Look for frost or ice on interior window frames.
Check for condensation between double-pane glass
Inspect weatherstripping for cracks, gaps, or deterioration.
Look for daylight around door frames.
Why This Matters:
Drafts aren’t just uncomfortable—they’re expensive. You’re literally heating the outdoors. Plus, moisture from those drafts causes rot, mould, and paint damage around windows and doors.
What to Do:
Quick fixes:
Replace worn weatherstripping ($20-50 per door)
Apply fresh caulk around window frames
Use door draft stoppers
Add window insulation film for winter
Spring projects:
Replace failed window seals
Consider new windows if frames are rotting.
Repaint and seal exterior door/window trim
When to call a pro: If you see rot around frames, if windows are broken or won’t open/close properly, or if condensation is between panes (seal failure). Taking these steps can significantly improve your home’s energy efficiency and comfort. Additionally, regular maintenance can prevent larger issues and save you money in the long run.

6. Deck and Railing Safety (Snow Weight and Wood Damage)
What to Look For:
Before the next big snow (or after one melts): Inspect your deck and railings for any signs of wear or deterioration. Pay close attention to loose boards, rusted fasteners, and any areas where moisture may have accumulated, as these can compromise the structural integrity of your outdoor space.
Sagging deck boards or joists
Loose railings (grab and shake them)
Rotting wood can cause soft, spongy spots.
Popped nails or screws
Cracks in support posts
Separation from the house
Why This Matters:
Heavy snow can stress your deck beyond its design limits. Wet-dry-freeze cycles rot wood fast. A collapsing deck poses a serious safety hazard, potentially leading to a lawsuit if someone sustains injuries.
What to Do:
Safety first:
If anything feels loose or looks damaged, STAY OFF the deck.
Remove heavy snow loads promptly (but carefully).
Mark problem areas with tape
Assessment:
Photograph all the damage.
Test structural integrity (but don’t put weight on questionable areas).
Plan repairs for spring
When to call a pro: Any structural concerns, significant rot, or separation from the house requires immediate professional evaluation. Don’t wait—someone could become hurt. This cautionary note emphasizes the necessity of addressing potential hazards promptly to prevent accidents. By seeking professional help for serious issues, you can ensure the safety of everyone using the deck.

7. Attic Inspection (Insulation and Ventilation Issues)
What to Look For:
If you can safely access your attic, check for any signs of moisture or water damage, as these can indicate ventilation problems or potential leaks. Additionally, assess the insulation for gaps or compression, which can significantly impact your home’s energy efficiency.
Frost on the underside of roof sheathing (ventilation problem)
Wet or compressed insulation (roof leak or condensation)
Daylight through roof boards (holes, gaps)
Animal entry points (squirrels and raccoons love winter attics)
Ice buildup in attic space
Why This Matters:
Your attic tells the story of your home’s winter health. The problems here include ice dams, high energy bills, roof damage, and mould throughout your house.
What to Do:
Document what you see:
Take photos
Note areas of concern.
Don’t disturb the insulation if it’s wet (it could be asbestos in older homes).
Simple fixes:
Add insulation where it’s thin (spring project)
Improve ventilation (soffit and ridge vents)
Seal air leaks from living spaces below.
When to call a pro: Any signs of roof leaks, significant frost buildup, animal damage, or wet insulation require professional inspection. If not addressed properly, these issues can lead to further damage or health risks. A professional can provide the expertise needed to assess and rectify these problems safely and effectively.
