Buying or living in an older home has many perks. You get character, charm, and mature neighbourhoods. But older homes also come with age-related issues that every homeowner should know about. If you live in Calgary or Edmonton, these signs matter even more because of our long winters and big temperature swings.
How Alberta’s climate affects older homes
Calgary and Edmonton have tough climates. Winters are long and very cold. Temperatures can swing fast, especially in Calgary with its Chinook winds.
These shifts put stress on building materials in older homes. Wood can expand and contract. Foundations can shift as the ground freezes and thaws. Strong winds and heavy snow also wear down roofs, siding, and windows.
Because of these conditions, older homes in this region often show more drafts, cracks, and heating issues than homes in milder climates.
Below are the most common issues to watch for in older Alberta homes and what they mean for you.
1. Aging electrical systems
Many older homes still have outdated wiring. You might see knob and tube wiring, or aluminum wiring. These systems can be unsafe and are not designed for modern appliances.
Flickering lights, warm outlets, or tripping breakers are warning signs. An electrician can inspect your system and update it so your home stays safe.
2. Poor insulation and drafty rooms
Homes built decades ago often have low insulation levels. Cold air can sneak in around windows and doors. Warm air escapes through the attic or walls.
This makes your furnace work harder in winter and increases energy bills. Adding insulation and sealing drafts makes your home more comfortable and efficient.
3. Wear & tear on the furnace & A/C
Older homes usually come with older HVAC equipment. If the furnace or air conditioner is more than 15 years old, it may not heat or cool as well as it should.
Strange noises, uneven temperatures, or rising energy bills are signs of trouble. Regular maintenance from a professional can help extend the life of your system. If repairs become frequent, it may be time to consider a replacement.
4. Plumbing problems
Pipes in older homes can corrode or leak over time. Some older homes still have galvanized steel pipes. These can rust inside, leading to low water pressure and discoloured water.
Frequent leaks, slow drains, or water stains on walls and ceilings are signs to investigate. A plumber can assess your pipes and recommend repairs or upgrades.
5. Foundation cracks
Calgary and Edmonton both experience freezing and thawing cycles. These cycles can cause soil movement and stress the foundation of an older home.
Small cracks are normal. Large or growing cracks need attention. They can lead to water leaks or structural issues if left untreated.
6. Roofing issues
Roof materials break down over time. Shingles can curl, crack, or fall off. Ice dams are also common in older homes with poor insulation or ventilation.
If you notice missing shingles or water spots in the attic, your roof may be near the end of its life. Timely repairs help prevent bigger problems.
7. Moisture & mold
Older homes may have poor ventilation and aging materials. This can lead to trapped moisture and mold growth.
You might notice a musty smell, peeling paint, or dark spots on walls. A professional can find the source and help you fix it before it spreads.
8. Windows that lose heat
Old single pane windows are common in older homes. These windows lose heat quickly during Alberta winters.
Upgrading to energy efficient windows reduces drafts and cuts heating costs. Even simple fixes like weatherstripping can make a difference.
When to get help
If you notice any of these issues, a professional inspection can save you time and stress. Many homeowners in Calgary and Edmonton choose a home services provider to stay ahead of problems. Regular HVAC tune ups, plumbing checks, and electrical inspections help you protect your investment.
