Boarding a window in Floral Park is not the same job as boarding one in a tract house. The sash, casing and trim on these 1920s and 1930s homes are old-growth material with no modern equivalent. You can replace glass. You cannot buy that wood back. So the board-up gets built to put zero fasteners into historic material: panels braced from the interior against structural framing, or an exterior cover carried on clamps and standoffs that bear on the stucco field rather than into the casing.
The same principle applies up top. Santa Ana's designated districts, Floral Park, French Park and Washington Square, sit under steep roofs that have collected layers across a century, frequently with wood shingle still buried in the stack. Permanent repair on a contributing structure goes through historic preservation review, which takes time, and that's precisely why the temporary cover has to be a real one built to hold for weeks rather than days. The plaster below is the reason for urgency: wet plaster releases its key from the wood lath and comes down in sheets.
What Santa Ana Changes About Board-Up & Tarping
1No fasteners into original sash or casing
The standard board-up screws plywood straight through the casing, and on a house in a designated district that's damage you can't undo. We brace from inside against the rough framing, or clamp an exterior panel with standoffs bearing on stucco. It takes longer per opening, and it means the original window comes back exactly as it was, which is most of the reason people own these houses.
2Preservation review runs on its own clock
Permanent exterior repairs on a contributing structure in Floral Park, French Park or Washington Square go through review, and that process does not move at the speed of a storm. Plan on the temporary cover being in place for weeks, not a long weekend. We build to that from the outset, and we document pre-loss condition thoroughly, because review goes far more smoothly with photographs of what was actually there.
3Plaster keys let go without warning
Lath-and-plaster holds several times the water drywall does and hides it well. What fails isn't the plaster surface, it's the key, the plaster that squeezed between the lath strips and locked it in place. Once that saturates, a ceiling that looked sound drops all at once. When we find a bulging ceiling we relieve it in a controlled way rather than leaving something overhead to fall on its own schedule.
How the Work Runs
The method is the same one we use on every board-up & tarping job, documented to the IICRC S500:2025 standard. Here it is in short — the full emergency board-up & roof tarping process explains each stage in detail.
- Safety and structure first
- Photograph the opening before we cover it
- Dry-in the roof opening
- Board and brace the openings
- Shore what is carrying load
- Handle the water already inside
The Santa Ana Background Worth Knowing
Lath and plaster is wood strips nailed across the studs with several coats of plaster troweled over them. The plaster that squeezes through the gaps between lath forms keys that hook over the wood and hold the whole wall in place. That construction is why plaster walls last a century — and why they behave so differently from drywall when wet.

What It Costs in Santa Ana
We do not quote a number over the phone before seeing the property — anyone who does is guessing. The variables that actually move the price on a board-up & tarping job are area covered and roof pitch, number and size of openings, conditions at the time of the call, and they are broken down in full on the emergency board-up & roof tarping page. The assessment and the written estimate are free anywhere in Santa Ana, day or night, with no obligation.
Board-Up & Tarping Questions from Santa Ana Homeowners
Emergency protection isn't a permanent alteration, so securing your house against weather and entry tonight is not what preservation review is about. It's the permanent repair, replacement windows, roofing material, exterior changes, that gets reviewed. As for damage, it depends entirely on who does the work. We won't put a fastener into original sash or casing. Interior bracing and clamped exterior panels do the same job and leave nothing to repair when the glass goes back in.
A properly fastened tarp on a sound deck holds for weeks and gets you through the rest of a wet season. We have had covers stay tight for a couple of months while claims and permits worked out. That said, it is temporary by design — the material degrades in UV, and every storm works on the edges. If yours is going to be up longer than a few weeks, we come back and check it rather than assuming.
Usually not. Most policies require you to take reasonable steps to prevent further damage and allow emergency mitigation without waiting for an adjuster — waiting is often the thing that creates a coverage argument. Call your carrier and open the claim, then let us secure the building. We photograph everything before and after and give you an itemized invoice, which is what the adjuster needs to approve the emergency line separately from the repair scope.
Usually, if drying starts quickly. Plaster holds much more water than drywall and dries far more slowly, so it needs more equipment and often desiccant dehumidification. The risk is the plaster keys softening and releasing from the lath, which is why waiting is the one thing that genuinely costs you the wall.
