The Bottom Two Feet Fail First

Snow banked against the base of a wall does not behave like rain. Rain wets a surface and runs off within hours; a snowbank sits there for weeks, keeping whatever is behind that band of wall saturated the entire time it is melting slowly from underneath. Six feet higher, the coating is only dealing with occasional storms passing through.

That sustained contact is harder on both wood and stucco than the cold itself is. Wood swells and eventually softens; stucco takes water in through any hairline crack and holds it. The paint over either one is being asked to do a job ordinary exterior coating was not specified for, which is exactly why that band fails years ahead of the wall above it. It is a moisture problem wearing paint failure as its symptom, not a paint quality problem on its own.

Often, yes. A wall that sees occasional rain and dries between storms can be coated with a standard exterior product and hold up well. A band that spends weeks in contact with melting snow needs something suited to sustained moisture — that can mean a different film thickness, a different product line, or simply making sure the substrate underneath is genuinely dry and sound before anything goes on top of it.

What does not work is coating that band with the same product used higher up and expecting the same result, because the exposure is not the same. We specify the snow-contact band separately in the estimate so you can see that it is being treated as its own problem rather than an afterthought tacked onto the rest of the job.

Sometimes, and it is worth a conversation even though it is outside the paint itself. Where a roof sheds snow directly onto a lower wall, or where plowed snow is routinely piled against one side of the house, redirecting that — a small change in where snow gets pushed, or attention to how a roofline drains — can meaningfully reduce how much contact that wall takes each winter.

We will point this out when we see it during the estimate, because a repaint that ignores an ongoing cause is repainting the same failure on a delay rather than solving it. It does not change the scope of the painting work, but it is the kind of detail worth knowing about your own property, and it can extend how long the repair actually holds.

That depends on the rest of the elevation. Where the upper wall is still sound and only the base has failed, treating the band on its own is legitimate work rather than a shortcut, and it is a smaller job. Where the whole wall is aged and the base is simply the part that failed first, doing the elevation together makes more sense.

We assess that at the walkthrough rather than assuming either answer. What matters most is that the repair in that band is done properly — sound substrate, correct product — regardless of how much of the rest of the wall is included, because a good base repair under a mismatched upper wall still holds, while a rushed base repair under a freshly painted upper wall fails again on the same schedule.

Above the snow line, ten to fifteen years is realistic on a well-prepared wall, similar to what you would expect at lower elevations with good prep. In the snow-contact band itself, expect a shorter cycle even when it is done properly, simply because sustained moisture contact is a harder condition than sun and rain alone.

What shortens that further is skipping the repair step — coating over wood or stucco that is still holding moisture from the winter before rather than letting it dry and repairing what needs it. That is the single most common reason a base band fails again within a year or two of a repaint, and it is avoidable with the right sequence rather than a different product.

Yes, and in the snow-contact zone that repair is often the larger part of the work. CSLB #1105333 is a Class B General Building licence, which covers wood and fascia repair and stucco patching in the same scope as the coating, with licensed specialty trades coordinated where a scope calls for them.

Coating over wood that has already swollen or stucco that is still holding water from the last thaw is the most common way a repaint fails within a season in this band specifically. Being able to replace what needs replacing and patch what needs patching, rather than simply painting what is there, is what makes the repair actually hold through the next winter rather than just looking finished for one season.
