Monday, November 9, and the front stair is still dark after the shower. The walk beside it has lightened. The treads have not. A green film sits on the nosing, and the handrail is slick where a hand would close.
Steady rain does not rinse that run. It keeps a thin algae coat wet and packs Douglas fir needles and cedar scales into the joint at each riser. Nanaimo receives over 1,100mm of rain a year, and mid-November is when short days, and a first frost on a clear dawn, stop a shaded stair from drying between systems.
This post stays on the front stair: the treads you stand on, and the handrail you grab. The sidewalk, the door, the siding, and the glass are the front entry guide. A wood deck and the stairs off it are the deck and stairs guide. The leaf by the bins is the side-gate guide. A storefront or a strata common stair is the storefront and strata walks guide. Cleaning is not stair repair, and it is not a new rail.
Why the front stair stays slick once November evenings go dark
A September afternoon still puts light on a south-facing run. After the clocks changed on Sunday, November 1, that same stair is in shade by mid-afternoon, and a north entry under western red cedar may not see the sun at all. The landing can look ordinary from the street while the second tread is still holding last night's rain.
A shelf you stand on
A vertical riser sheds. A tread is a shelf. Rain lands on the flat, pools along the nosing, and sits in the joint at the riser. Concrete holds a black film that looks like a stain until a shoe skates. Wood holds it in the grain. Paint hides it under a gloss that goes greasy when wet. A smooth coat is enough for a guest who does not know which step is the slick one. Needles packed against the nosing keep that shelf wet after the walk beside it has lightened.
The rail you close your hand on
The tread is what the shoe meets. The handrail is what you trust when that tread is already wet. A wood rail films green on top, where the hand sits, and in the checks. A metal rail takes a black coat that feels like oil after dark. Vinyl does the same, and a close jet can scar it. The bracket at the bottom stays wet longest, where eave drip meets splash off the lowest tread. A rail can look clean from the sidewalk and still skate under a glove. If it moves when you lean, that is a fastener. A wash will not tighten it.
Shade, a first frost, and this week's visits
North Nanaimo and Lantzville often have Douglas fir or western red cedar over the entry, so the treads sit in drip all month. Parksville and Qualicum Beach add Oceanside damp. Ladysmith and homes in Cedar see the same dark nosings where the run misses a dry afternoon.
A clear dawn can put a white tip on a tread that was wet at midnight. Frost on algae is slicker than frost on bare concrete. Scraping takes the surface and leaves the growth, so leave it. Remembrance Day is Wednesday, November 11, and early holiday visits start the same week. Guests use this run with a bag in one hand. The porch light does not show the film. A downspout on the bottom step feeds that one tread while the steps above look ordinary. If the water comes from a packed trough, gutter cleaning with a full downspout flush belongs with the stair.
The treads, the nosings, and the rail
The landing is what you notice from the sidewalk. The water sits on the shelves: each tread, the nosing, the joint at the riser, and the rail beside them. Shade, drip, and needles meet there, so those surfaces stay wet after the walk has shed.
Where the growth actually sits
On concrete, moss fills the control joint and the crack at the house, and algae films the flat and the nosing. Exposed aggregate hides that film until a shoe skates. Pavers hold a green line in every joint. Wood holds moss in the grain and at the cut end. A metal stair films black on the tread and the rail, and a worn non-slip strip can be slicker than the metal once the grit is gone.
A dark band only under a spilling gutter means the stair is being fed. If the slick square is the pad under a side leaf, that is the gate. Steps built into a concrete or stone garden wall belong with that wall. This post is the stair to the front door.
What you can see from the walk
Stay off a wet tread you do not trust, and leave the ladder down. After a shower, look along the run in daylight from the side and stop if a shoe skates. The colour on the nosing is one clue. The feel of the rail is the other.
- A tread that stays dark after the walk has lightened. That shelf is holding water.
- A shoe that skates on the nosing, moss cushion or not. The film is the problem.
- Green or black film on the top of the handrail, and in the checks. That is the grip.
- Needles and cedar scales packed at the riser. They keep the tread wet.
- A white tip at dawn on a green tread. Frost on film. Do not scrape it.
- A nosing that rocks, a crack you can see through, or a rail that moves. The film is a wash. The movement is not.
Concrete, wood, and metal are not the same wash
One entry often has a concrete tread, a wood nosing, and a metal rail on the same afternoon. A close jet that suits sound concrete will raise the grain on a wood tread and scar a vinyl rail.
| What you see on the stair | What it usually means | Sensible next step |
|---|---|---|
| Moss or black film on sound concrete, brick, or pavers | Growth on a hard surface that can take a rinse | Soft wash, then pressure where the surface is sound. Do not scrape |
| Green film on a wood, painted, or composite tread | Algae in the grain or on a finish that can stripe | Soft wash and dwell. Pressure raises the grain and can lift a weak nosing |
| Algae on a metal tread or a metal rail, finish sound | Film on metal that stays damp | Soft wash, then a gentle rinse. Keep a close jet off a thin rail |
| Green on a wood or vinyl rail, rail solid | The grip is filmed | Soft wash the rail. A blast scars vinyl and lifts a stain |
| A dark band only where a gutter or cedar drip lands | The lowest treads are being soaked from above | Open the gutter and the downspout, then wash that run |
| A rocking nosing, spalled concrete, a soft stringer, or a rail that moves | A repair, with film on top of it | A qualified contractor before a wash will hold |
Do not scrape a tread to hurry the colour. A knife or a wire brush takes the surface and leaves growth in the pores. On concrete it polishes the spots that were already slick.
What a careful clean looks like
Mid-November still has mild gaps between systems. Rain mid-visit rinses a treatment off before it has worked, so the solution needs time to sit. A frost at dawn means the stair may be icy first thing. Book the gap, and leave the ice alone.
Treat the growth, then rinse where the surface can take it
Soft washing puts an eco-friendly biodegradable solution on the growth at low pressure and leaves time for it to work. That is the start on concrete, on a wood or painted tread, and on a wood, metal, or vinyl rail. A close jet on a wood nosing drives water into the end grain and can lift a loose edge.
Pressure washing belongs on sound concrete, brick, and durable pavers after the film has been treated. A blast on its own stripes the surface and leaves growth in the pores. Keep it off wood treads, painted steps, a thin rail, and any nosing that already chips. House washing beside the door is a separate pass.
A sensible order when the stair is being fed
- The water path first. If a gutter dumps onto the lowest tread, flush that downspout before the stair is the finished surface.
- Roof growth next, if it sheds onto the run. On a sound roof, moss removal and roof cleaning come first. The site FAQ says most Nanaimo roofs stay moss-free for 3-5 years with soft wash and ridge zinc strips. That claim is about the shingles, not these treads. Failing shingles go to a roofer.
- Loose needles off the treads, without scraping the surface or packing debris into the joint.
- The treads and the handrail, solution where the growth is living, then a rinse the material can take. Siding beside the stair waits until the splash stops.
- The walk and the landing, if they share the booking. The front entry guide is that scope. Glass the rinse will hit comes last. Window washing is that pass.
Name a bed, a pond, or a rain barrel beside the run before the rinse. The garden, pets, and rain barrel guide is the longer note. A stair that serves more than one suite is commercial services. If the week of Wednesday, November 11, is solid rain, book the next opening so the solution can sit.
What a wash will not fix
A clean stair is easier to read under a porch light. It is not a repaired nosing, and it is not a promise that a shaded run will stay dry.
A loose tread stays loose
A nosing that rocks, concrete that has spalled through, a stringer that gives, or a handrail that moves in its bracket is contractor work. Book that repair first. A crew can wash a sound tread. They cannot reset a nosing or fasten a rail that has nothing left to hold a screw. Washing a failing edge can knock more of it away.
Clean is not a grip coating
A wash removes moss and algae. It does not install a non-slip strip, a stain, or a sealer. Rain on smooth concrete is still rain, and a worn factory strip can stay slick once the grit is gone. Growth under cedar comes back. November is a reset before the first visits, not a dry stair until spring. If a clear night ices the film, stay off it. Cleaning is not a guarantee against a slip.
Questions from the front stair
Will November rain wash the steps clean? Rain wets the film and moves a few loose needles. A tread that looked dusty in October can skate by the second week of the month. Rain does not lift the coat on the nosing or on the rail.
Can a close jet replace a treatment? On sound concrete, pressure lifts dirt after the growth has been treated. On a wood tread, a painted step, or a rail it raises the grain, stripes the finish, or scars the vinyl, and it drives water into a cut end. Those surfaces take soft washing.
The walk was cleaned in October. Why are the treads still green? A walk wash stays on the flat that was in that scope. Each tread is a shelf the path sheds, and November has kept that shelf wet. The rail was often left out of that booking.
Does a clean rail mean the stair is safe after dark? It removes moss and algae that make a wet tread and a wet grip worse. Smooth concrete, rain, frost, and a needle mat can still be slick. Cleaning is not a coating, not a repair, and not a guarantee.
Book the steps before the dark stretch settles
After the next shower, walk the stair once in daylight. A tread that stays dark, a shoe that skates on the nosing, or a handrail filmed green is the November problem on a front stair. Book those treads and that rail while a mild gap still exists. A rocking nosing, a soft stringer, or a rail that moves goes to a contractor first. Cleaning is not that repair.
