Sign Maintenance

A well-made Nantucket quarterboard can last decades — sometimes longer than the house it hangs on. The wood is solid, the paint is built to weather, and the lettering is carved in rather than printed on. But “built to last” doesn't mean “maintenance-free.” Like any quality piece of exterior woodwork, a quarterboard rewards a little attention with a lot more years on the wall.

Here's what you need to know to keep your sign looking right for as long as possible.

Cleaning Your Quarterboard

Dust, pollen, salt air, and the occasional spider web — these are the things that settle on an outdoor sign over time. A periodic cleaning is usually all it takes to keep the surface looking sharp.

Use a soft cloth or soft-bristle brush with mild soap and water. Avoid anything abrasive — scrubbing pads or stiff brushes will scratch the painted surface. Work gently across the face of the sign, including into the carved letters where debris tends to collect. Rinse with clean water and let the board dry fully before rehanging.

Salt air is particularly aggressive on the coast, and Nantucket sees plenty of it. If your sign is mounted in a location with direct ocean exposure, a seasonal rinse in spring and fall will help extend the life of the finish significantly.

Protecting the Finish

The painted surface on a quarterboard is your first line of defense against moisture and UV. When the paint is in good shape, the wood beneath it stays stable. When the paint starts to crack or peel, moisture gets in — and that's when you start to see real problems.

A thin coat of exterior-grade clear sealer or paste wax applied to the face of the sign every few years adds a layer of protection without changing the appearance. This is particularly useful if your sign gets direct sun exposure for most of the day. UV breaks down painted surfaces faster than almost anything else.

If you notice the paint looking dull or chalky, that's the first sign that UV protection has worn off. Address it sooner rather than later — it's much easier to protect a paint surface in good condition than to restore one that has already started to fail.

Touch-Ups and Minor Repairs

Small chips and scratches in the painted surface are normal for any exterior sign. They don't necessarily mean the sign needs full refinishing — in many cases, a careful touch-up with matching paint is all that's needed.

If you know the color your sign was painted in, touch-up is straightforward. If you're not sure, we can often match it from a photo, or by referring back to your original order if we made the sign. We keep records of the colors we use and can usually provide touch-up paint or mix a close match.

The carved lettering is more durable than the flat painted areas and rarely needs attention on its own. If you notice a letter looking thin or faded, that's typically a surface issue rather than a structural one — touch-up paint will sort it out.

When to Bring It Back In

Some signs eventually need more than routine maintenance. If the paint has failed across a significant portion of the board, if the wood shows signs of moisture damage, or if the sign has taken physical damage — a branch, a ladder, a wayward vehicle — it may be time for a proper refinish.

We refinish and restore quarterboards. The process involves stripping the existing paint, assessing the wood for any damage, sanding back to a clean surface, and repainting and retouching as needed. In most cases, a refinished board comes out looking better than it did when new — because the wood has had time to settle and the carving is already done.

If you're not sure whether your sign needs maintenance or restoration, send us a photo. We're happy to take a look and give you an honest assessment.
