Common Siding Problems in Edmonton and How to Fix Them
Edmonton’s climate is hard on siding. Cold winters, freeze-thaw cycles, sudden chinook thaws, and summer hail all wear on exterior materials. At Weber Exteriors, we help homeowners catch these problems early, before they lead to water damage or structural issues. Below are the most common problems and what a professional repair involves.
1. Cracks and Holes
Cracks and holes come from weather, impacts, and age. In Alberta, hail season typically runs from June to September, with the highest risk in June and July (ATCO Energy). Vinyl is especially easy to damage with hail (Acera). Left alone, cracks let water into the wall.
- Vinyl siding: small cracks are sealed by a technician using materials matched to your siding. Larger holes usually mean the damaged section needs replacing. Learn more on our vinyl siding repair page.
- Hardie board: repairs need the right materials and technique to hold up to Edmonton weather. A technician decides whether to patch or replace the affected boards. See our Hardie board repair page.
- Cedar siding: repairs need proper preparation and a colour match so they don’t show or let moisture in. See our cedar siding repair page.

2. Warping and Buckling
Warping usually comes from improper installation, heat exposure, or moisture behind the panels. Vinyl loses flexibility in the cold and is more likely to crack below freezing (Krumm Exteriors).
- Vinyl siding: a technician checks the cause and replaces any sections that can’t be saved.
- Wood siding: warped wood often needs replacing, with proper sealing and painting to prevent it from happening again. Our siding repair team can assess the damage.
If you see warping, call 587.337.2446 so the cause is found before more panels are affected.
3. Fading and Discolouration
Sunlight and harsh weather fade siding over time. Sun also dries out caulking around windows and doors, which becomes brittle and shrinks (ATCO Energy).
- Vinyl siding: faded vinyl is usually repainted by a technician, using paint designed for vinyl surfaces.
- Hardie board: repainting needs proper preparation and UV-resistant paint.
- Cedar siding: faded cedar needs sanding, staining, and sealing done correctly.
If the caulking around your windows or doors is cracked or shrunken, have it checked. Contact us or call 587.337.2446.
4. Mould and Mildew
Mould and mildew are unsightly and can affect indoor air quality. They form in damp, shaded areas with poor ventilation.
Gently clean the affected area with water and mild detergent, then rinse with clean water. If mould keeps coming back, moisture may be getting behind the siding. That needs a professional inspection: book one or call 587.337.2446. If moisture has spread into the structure, our water damage team can assess it.
To prevent mould, keep the area ventilated, reduce moisture around the siding, and clean it regularly.
5. Loose or Missing Siding
Strong wind, improper installation, or age can loosen siding or remove sections completely.
- Loose siding is a structural issue. Reattaching it correctly takes the right fasteners and alignment, so a technician should secure it.
- Missing sections need matching material and a secure installation. Our siding repair team can source and fit the replacement.
Call 587.337.2446 to have loose or missing siding secured before the next storm.
6. Insect Damage
Termites and carpenter ants can seriously damage wood siding. Look for small holes, sawdust, or wood that sounds hollow when tapped.
If you find signs of insects, contact a pest control professional first. Then have a siding technician replace damaged sections and check that the new material is treated to resist infestation. Book an inspection to assess the full extent of the damage.
7. Peeling Paint
Peeling paint on wood siding usually comes from moisture getting in or poor surface preparation. Repainting without fixing the cause means the problem will return.
A technician removes the loose paint, prepares the surface so the new paint bonds properly, and applies exterior-grade primer and paint designed for wood siding. Call 587.337.2446 for a free assessment.
8. Moisture Damage
Moisture can lead to rot, mould, and structural damage. It is most common in wood siding but can affect other materials when water gets in.
Rotted or damaged siding needs replacing once the cause is found and the structure behind it is checked for moisture and mould. To prevent moisture damage, keep gutters and downspouts clear so water drains away from the siding, and maintain protective sealants and paint.
