Crawl Space Repair in Amelia Island
Why Amelia Island homes need this, and how we do it
The Fernandina Beach historic district is full of homes set on brick piers over sand, many of them framed in old heart pine that has outlasted several owners. What wears out first is usually where wood meets masonry: sill plates on damp brick, beam ends tucked into pier pockets, and joists below old bathrooms that have taken a few leaks. The newer neighborhoods toward the south end have younger framing, but a bad vent layout or a clogged drain can rot a floor there in under ten years.
Our repair process is the same on both ends of the island. We find every failed piece with a probe and a meter, remove it, and rebuild in treated lumber. Sills get replaced in sections, joists are sistered or renewed, and subfloor is replaced from below so finished floors above stay in place wherever possible. On historic homes we keep original material that is still sound and work around old brick with care.
Florida dew points hold high from late spring into fall, so we always fix the moisture source before we leave. That might mean a new sump, cleared drain lines, repaired vent covers, redirected downspouts or a plumbing repair. Encapsulation is available as a separate option for spaces that need sealing. Expect one to three days on site, a fixed written price and a full photo report.

Questions Amelia Island homeowners ask us
My Fernandina house sits on old brick piers, can you fix the wood without messing with them?
Yes. We replace the rotted sills and beam ends while keeping the brick piers in place, and we treat the old masonry gently the whole time.
My bathroom floor on Amelia feels spongy, is that a big repair?
Usually it's a section of subfloor and maybe a joist or two under the tub or toilet. We fix it from below, fix the leak, and your tile or flooring upstairs usually stays put.
Is there mold down there if my crawl space smells funky?
Pretty likely, especially in Florida humidity. We clean and treat any mold on the framing, replace wood that's gone weak, and fix the moisture that let it grow.
I'm selling my Amelia Island home and the inspector flagged the crawl space, can you help?
Yep, we see that a lot. We'll look at what the inspector found, give you a fixed written price, and the photo report after the repair is something you can hand right to the buyer.
Do you use treated lumber for the repair?
Yes, all new sills, rim joists and sistered joists are pressure treated, and fasteners are rated for coastal conditions.
