Is it a good fit for a Sarnia home?
- Does not rot
- Can be repainted with proper preparation
- Existing panels can sometimes be selectively repaired
- Metal construction is not attractive to insects
- Lightweight compared with cementitious cladding
Where this material can disappoint
- Dents can be conspicuous
- Older colours and profiles can be hard to match
- Oxidation/chalking affects paint preparation
- Dissimilar-metal interfaces can create corrosion concerns
- Repairs can look patchy beside weathered siding
These are not reasons to reject the material. They are the details to understand before selection. Product line, exposure, colour, profile and installation quality can change the result substantially.
Installation details that matter
- Use compatible fasteners and accessories
- Avoid trapping water at horizontal transitions
- Detail dissimilar-metal interfaces appropriately
- Respect panel movement requirements
- Assess old wall layers during replacement
The manufacturer’s current installation instructions should govern fasteners, clearances, flashing and accessories.
Maintenance and repair
Sound existing aluminum may be worth cleaning and repainting instead of replacing. Local dents or loose panels may be repairable, while broad damage can justify re-cladding.
How to compare it with other siding
Compare appearance, maintenance, repairability, installed cost and the wall details required—not just the panel price. Use the Sarnia material comparison and cost guide.
Questions about Aluminum Siding

Can you match old aluminum siding?
Sometimes, but older profiles and colours can be difficult to source.
Is aluminum siding still used?
Yes, though homeowners now have more vinyl, fibre cement, engineered and metal alternatives.
Should dented aluminum be repaired or replaced?
It depends on the extent of damage and material availability.
