My stairs creak under the carpet. Will replacing the carpet fix the noise?

Replacing the carpet alone will not fix creaking stairs - the noise is coming from the stair structure underneath, not the carpet itself. The carpet is actually helping to muffle the creaks that would be even more noticeable on bare wood.

Stair creaks are typically caused by loose connections between the stair treads (the horizontal part you step on) and the risers (vertical back part), or between the treads and the stringers (side supports). Over time, the nails or screws holding these components together can work loose due to the constant foot traffic and seasonal wood movement. Temperature and humidity changes cause the wood to expand and contract, which gradually loosens the fasteners.

In Ottawa's climate, seasonal movement is particularly common due to our significant temperature swings and indoor heating cycles. Many homes built in the 1970s-1990s have stairs that develop creaks as the original fasteners loosen. The good news is that this is usually a structural maintenance issue rather than a safety concern, though it should be addressed properly.

To actually fix the creaking, you'll need to re-secure the loose connections from underneath the stairs (if accessible) or from above by driving screws through the treads into the risers and stringers. This work should be done before installing new flooring. A qualified contractor can identify exactly where the movement is occurring and reinforce those connections with appropriate screws or brackets.

When you do replace the flooring, consider your options carefully. Carpet will continue to muffle any remaining minor creaks, while hard surfaces like hardwood or luxury vinyl plank will make any structural noise more noticeable. Many Ottawa homeowners choose to install hardwood stair treads with matching nosing, which typically runs $80-150 per tread installed, depending on the wood species and complexity.

For a proper assessment of your stair structure and flooring options, request a consultation from Ottawa Floor Install. We can evaluate the underlying cause of the creaking and recommend the best approach for both structural repairs and your new flooring installation.
