St. Augustine's Spanish colonial and Victorian homes are among the oldest continuously occupied residential buildings in America, and their wood framing carries the weight of centuries. When wood rot, termite damage, or structural wear shows up in the sills, joists, fascia or trim of a 1800s cottage or a turn-of-the-century Queen Anne, the work demands someone who knows old-house carpentry and won't rush a diagnosis.

Jacksonville Carpentry has served St. Augustine and the surrounding Jacksonville area since 2016. We're a local carpentry shop, not a franchise. The same carpenters who inspect your floor joist or assess rot in your exterior trim are the ones who do the repair. We explain what we find, propose repair whenever the wood justifies it, and price the work honestly.

Carpentry in St. Augustine (32084)

St. Augustine's housing stock spans three centuries. You'll find hand-hewn timber frames in colonial-era homes, balloon-framed Victorian rowhouses on tight downtown lots, early-1900s bungalows with brick pier foundations and ventilated crawl spaces, and mid-century frame cottages scattered through established neighborhoods. Many homes sit within a few blocks of the Intracoastal or tributary creeks, where humidity, salt air, and seasonal moisture swings accelerate wood decay. Older crawl spaces often lack modern vapor barriers, and ground moisture wicks up into sill plates and rim joists year-round. Wood rot and dry rot are the most common repairs we see here, followed by termite damage discovered after a pest inspection.

The ground in St. Augustine is typically sandy and well-draining, but homes built on low-lying lots or near water may experience standing water or poor drainage after heavy rain. Access to crawl spaces and under-deck areas can be tight, especially on narrow historic lots. We're accustomed to working in those tight spaces, coordinating with property owners on lot constraints, and respecting the architectural character of older homes when we repair or replace trim, doors, or exterior details.

Since 2016, we've repaired wood rot in sill plates and rim joists, replaced floor joists softened by moisture, rebuilt fascia and soffit on homes with decades of weather exposure, and installed finish carpentry and trim in homes where original details matter. We're fully insured and EPA Lead-Safe Certified, because many St. Augustine homes contain lead paint.

How a Job Works in St. Augustine

We start with a free on-site assessment. You describe what you've noticed (soft flooring, visible rot, damage found during a pest inspection, or cosmetic work you want done), and we look at the site, take measurements, and explain what we find in plain language. If access is tight or the lot is constrained, we note that during the walkthrough. We'll tell you whether a repair is sound or whether replacement is the honest answer.

Once you approve the estimate, we schedule the work. For structural jobs like floor joist replacement or beam work, we'll discuss whether a permit is required. St. Augustine's building department sets those rules, and we defer to them. We coordinate with you on access, timing, and any HOA notifications if your property is in a historic district or managed community. We do the work carefully, explain what we're doing as we go, and leave your property clean and your workspace organized when we're done.

Final walkthrough: we show you the completed work, walk through any details you want to understand, and answer questions before we leave.

Pricing depends on the scope, the condition of the wood, access to the work area, and whether permits or structural engineering are needed. Wood rot repair in a sill plate or rim joist typically runs from $650 to $2,000 depending on how much wood is compromised and whether the joist itself needs sistering or replacement. Floor joist and subfloor repair starts around $1,800 for a modest section; larger jobs or multiple joists cost more. Termite damage repair begins at $1,200. Finish carpentry like crown molding, baseboard, or trim installation starts at $450 to $550 for smaller rooms and scales up with the linear footage and complexity. Custom built-ins and shelving start at $1,900. Door installation (interior or exterior) ranges from $350 for an interior door to $850 and up for an exterior or entry door, depending on the frame condition and finish. Deck and porch repair starts at $900. Every job is unique, and the best way to know what your work will cost is to call us for a free estimate at (904) 605-8456. We'll give you a realistic price and explain the factors that drive it.

I found soft spots in my crawl space floor joists during a pest inspection. How do I know if a joist can be repaired or needs replacement?

We inspect the joist by probing the wood with a tool to find the depth of decay. If rot is only on the outer surface and the core is still solid, sistering a new pressure-treated joist alongside the damaged one is often enough. If the rot runs deep into the joist or affects more than half the cross-section, replacement is the honest answer. We'll take measurements, show you what we find, and give you a clear estimate for whichever approach makes sense.

My Victorian home is in a historic district. Do I need approval before you repair or replace exterior trim and fascia?

Many St. Augustine properties fall under historic district overlay rules. Before we start exterior work like fascia, soffit, or trim repair, you should check with the St. Augustine Planning Department or your local historic preservation board to confirm whether the work requires a certificate of appropriateness or design approval. We're happy to work with those requirements and can help you document the scope of the work for your application.

What does wood rot repair typically cost for a small section of sill plate under an exterior wall?

A localized sill plate repair usually starts around $650 to $1,000, depending on how much of the sill is affected, whether the rim joist above it is sound, and how accessible the area is. If the rot is extensive or has spread to the rim joist or framing above, the cost rises. We'll give you a firm estimate after we inspect the damage. Call (904) 605-8456 for a free on-site assessment.

If I need to remove a load-bearing wall or replace a beam, do I need a permit and an engineer?

Yes. Load-bearing alterations almost always require a permit from the St. Augustine building department and a licensed structural engineer to design the beam sizing and load path. The engineer provides the drawings and calculations; we build to those specifications. You'll need to contact your local building department to confirm the permit requirements and threshold for your specific project. We can work from the engineer's plans once you have them in hand.

Our home is part of an HOA community. Do you coordinate with the HOA before starting work?

We can. If your property is in an HOA community or a historic district, let us know during the initial call. We'll discuss any notifications or approvals needed, and we can help you document the scope of work for submission if required. Ultimately, you're responsible for confirming HOA or historic district requirements with your community manager or preservation board, but we're experienced in working within those constraints.

Are you fully insured for work at my home?

Yes. We carry general liability and workers' compensation insurance for all work we do. You'll receive proof of insurance before we start. We're also EPA Lead-Safe Certified, which is important for many St. Augustine homes built before 1978 that may contain lead paint.

What's the best time of year to address wood rot or structural carpentry in St. Augustine?

Wood rot and moisture damage don't follow a season in St. Augustine. Humidity and moisture are present year-round, especially in crawl spaces and near the water. If you've found rot or damage, the sooner you address it, the better. Waiting allows decay to spread deeper into the framing. That said, late spring through early fall can be busier for us, so if you're planning non-emergency finish work, scheduling in winter or early spring may mean faster availability. Call (904) 605-8456 to discuss timing for your project.
