Interior stairs, handrails & guards

Stairs need a graspable handrail (required once a flight has more than a couple of risers), uniform step heights, and guards around open sides and landings that are high enough, roughly 900 mm in homes, with openings too small for a child to slip through.

$150 to $600 to install a handrail; $1,000 to $3,000+ to rebuild guardsMonitorInterior

Why it matters

Falls on stairs are one of the most common home injuries, and inspectors check every flight. Older homes routinely have steep or winding basement stairs, "surprise" steps with non-uniform riser heights, and missing or loose handrails. On a listing advertising a basement suite, stairs and guards are part of whether that suite is actually usable and legal, alongside egress windows.

How to spot it

Grab the handrail and pull, it shouldn't move, and it should run the full flight. Walk the stairs and feel for one step that's different. Look at open-sided stairs and landings: is there a guard, is it rigid, could a small child fit through the openings? Carpet runners sometimes hide damaged treads.

What it costs

A wall-mount handrail runs $150 to $600 installed; rebuilding guards or newel sections $1,000 to $3,000+. (Internal estimates, handrail work is small-job pricing that varies by finish.)

What to do

Monitor / note for the inspector. These are usually inexpensive fixes, but on a basement-suite listing, treat missing guards or handrails as part of the suite-legality question and ask the municipality what was approved.
