Soffits and eaves: the part of the quote people forget

Soffits, the lined underside of the roof overhang, are normally painted as part of a full exterior repaint. They are also the line most often left vague on a cheap quote, because they are slow work: everything is done overhead from a platform, and the paint falls towards you rather than away.

What counts as the soffit?

The soffit is the horizontal lining under the eaves, running from the wall out to the fascia. On most Wellington houses it is fibre cement sheet, tongue and groove timber, or on 1960s and 1970s places a soft fibreboard product. Sitting in it you will usually find vents that feed air into the roof space. The fascia is the vertical board at the outer edge. People use the word "eaves" loosely for the whole assembly, which is precisely why quotes end up ambiguous.

Why do soffits cost more per square metre than walls?

Three reasons, and all of them are time.

• The work is overhead. You cannot lean into it. Coverage per hour drops, arms tire, and there is far more cutting in: a line along the wall junction, a line at the fascia, and a line around every vent.
• The access is not wall access. To paint under something you have to stand out from the wall, which is the worst possible position for a ladder. In practice it means a mobile tower, a trestle platform, or the scaffolding already up for the walls, which runs $1,500 to $4,000 or more on a full exterior job at 2026 prices.
• Protection takes longer. Everything below gets spattered. Decks, paths, joinery, plants and the neighbour's car all need covering before a brush goes up.

Labour sits at around $50 an hour in 2026, so slower square metres show up directly in the total. That part of the quote is not padding.

Why are the soffits filthy when they never get rained on?

For exactly that reason. Rain washes the walls. Nothing washes the underside of the eaves, so airborne dirt, salt and cobwebs build up year after year, and the shaded damp corners grow mould. In Wellington the wind drives grit and sea salt up under the overhang and then holds it there.

The practical effect is that soffits usually need more preparation than the walls, not less: a proper wash, a mould treatment wherever growth has taken hold, and sometimes a sealer over old chalky paint. Fresh paint applied over that grime will not stick, and the failure shows up as flaking sheets a season or two later.

What problems turn up under the eaves?

What you see	Likely cause	What to do before painting
Brown or yellow staining near the fascia	Gutter overflowing, or a leak at the roof edge	Fix the water first. Paint over a live leak and it bleeds through.
Sagging or swollen lining sheets	Soft fibreboard lining that has been wet	Replace the sheet. Paint does not stiffen a sagging board.
Vents clogged with old paint	Previous coats rolled straight over them	Clear them. Roof space ventilation matters more than a tidy line.
Black speckled growth in the corners	Mould in a shaded area rain never reaches	Treat and wash it off rather than coating over it.
Fine cracking along the wall junction	Normal building movement at an unsealed joint	Rake it out, seal with a flexible exterior sealant, then coat.
Flaking paint on a house from the 1980s or earlier	Possible lead-based paint	Get it tested before anyone sands anything overhead.

That last row deserves emphasis. Sanding an untested soffit on a house from the 1980s or earlier puts dust straight into your own face and onto whatever sits below, and Wellington has a great many houses old enough for it to matter.

Is painting your own soffits sensible?

On a single-storey house on flat firm ground, with a stable platform and sound lining, yes. It is honest work and you will save real money doing it. Allow roughly twice the time you expect, wear eye protection, and start at the far end so you are never reaching across wet paint.

Do not attempt it if the house is two storeys, if the ground falls away below the wall, if the lining is soft or stained, or if the paint is old enough to be lead-based and has not been tested. None of those are jobs to learn on while standing on a ladder at the wrong angle.

What should the quote actually name?

Ask for the words rather than the category. A clear exterior quote lists the soffit lining, any exposed soffit bearers, the fascia, the barge boards, the downpipes and the vents, and says how many coats each of them is getting. A line reading "eaves included" tells you nothing about whether the vents are being cleared or the mould is being treated.

Two further questions worth putting in writing: is the wash and mould treatment priced as part of the preparation or charged as an extra, and is lining replacement included or provisional. On a full exterior repaint these belong in the number from the start. If they are missing, the cheaper quote is not actually cheaper, it is just less complete.

One more thing to check before you sign. If the soffits are stained, get the cause diagnosed rather than described. A painter who tells you the staining comes from an overflowing gutter and should be fixed first is giving you better value than one who quietly prices a stain-blocking sealer over the top of a live leak.
