St. Louis is a brick city, and that means your wood needs attention. From the grand Victorian mansions of Lafayette Square to the iconic St. Louis flats across South City, Soulard, and Tower Grove, wood rot and termite damage are the quiet enemies of every homeowner here. We've been fixing the porches, trim, decks, and interior framing of St. Louis homes since 2016.

When your porch sill starts to soften, your fascia splits along the brick line, or a pest inspector flags termite damage in your floor joists, you need a local carpenter who knows the humid summers and freeze-thaw winters that drive wood failure in this city. That's St Louis Carpentry. We're fully insured, we work to the City of St. Louis Construction Industry Contractor License standard, and we explain what's happening to your wood before we price the repair.

Carpentry in St. Louis (63104)

St. Louis sits on limestone bedrock with red clay deposits that built this city in brick. That means wood shows up where it matters most: porch decks and sills, window frames and trim, interior framing, fascia and soffit, and the occasional deck or rear addition. The humid continental climate, with hot summers and cold winters that freeze and thaw, puts real stress on exposed wood. Spring thunderstorms and the occasional tornado risk mean we also see storm damage to exterior trim and porch framing. And the humidity in summer brings termite pressure that affects floor joists, rim joists, and sill plates across the city.

Our team has worked on brick rowhouses in Soulard, brick bungalows and Craftsman homes on The Hill, grand Central West End townhomes near Forest Park, and the Second Empire and Victorian mansions of Compton Heights and Lafayette Square. We know how to work on tight lots, navigate the grade changes along the Mississippi River bluff, and coordinate with the City of St. Louis on permits for structural work. Since 2016, we've been the carpenters St. Louis homeowners and property managers call when wood rot, termite damage, or structural carpentry needs doing right.

How a Job Works in St. Louis

You call us at (314) 338-6837 or reach out online. We schedule a free on-site assessment, usually within a few days. We'll look at the damage, explain what we see (wood rot, dry rot, termite damage, structural issues), and talk through repair versus replacement. We take photos and notes so you have a clear picture of what's happening.

Once you approve the estimate, we schedule the work. For structural jobs like floor joist replacement or load-bearing wall removal, we'll help you understand whether a permit is required, and we'll coordinate with the City of St. Louis Building Division on timing. We show up on time, bring our own tools and materials, and we do the work carefully. If we're working in a tight South City lot or on a steep grade near the bluff, we plan access and site setup so your neighbors aren't disrupted.

When the work is done, we clean up completely, walk you through the finished job, and answer any questions. You're left with solid, honest carpentry that will hold up to St. Louis weather for years to come.

Wood rot repair on a porch sill or fascia typically starts around $650 to $900, depending on how much wood needs replacing and how accessible it is. Termite damage repair to floor joists or subfloor framing starts around $1,200 and goes up with the extent of the damage and how much structural work is involved. A full floor joist or subfloor replacement usually runs $1,800 and up. Finish carpentry, crown molding, baseboard, and door installation range from $350 to $1,100 depending on materials and complexity. Custom built-ins and shelving start at $1,900. Deck and porch repair begins around $900, and beam replacement or load-bearing wall work starts at $3,500 and often requires a structural engineer and a permit. The real cost drivers are the size of the area, how deep the damage goes, site access, and whether the work needs a City of St. Louis permit. Call us at (314) 338-6837 for a free estimate tailored to your job.

I found soft wood on my porch sill in Soulard. Is this an emergency?

Soft wood on a sill or rim joist isn't an emergency, but it does need attention soon. Wood rot progresses as moisture cycles through freeze-thaw winters and humid summers. The longer it sits, the more wood you'll need to replace. A sill that's still mostly sound can often be repaired by cutting out the damaged section and sistering in new pressure-treated framing. If the rot has gone deep into the sill plate or the rim joist, replacement is the honest answer. Call us at (314) 338-6837 and we'll look at it within a few days.

My pest inspector found termite damage in my floor joists. What do I do?

First, get a copy of the pest inspection report so we can see exactly what they found. Termite damage typically shows up as galleries (hollow tubes) in floor joists, rim joists, or subfloor, and the wood becomes soft and crumbly. We repair and replace the damaged framing based on what the inspector documented. We do not treat the termites or offer pest control. That's a separate licensed trade. Once the wood is replaced and the area dries out, your pest control contractor handles any ongoing termite management. Call us with the report and we'll give you a realistic estimate.

How much does it cost to replace floor joists or subfloor in a St. Louis rowhouse?

Floor joist and subfloor replacement typically starts at $1,800 and climbs with the size of the area and the extent of the damage. A small section (say, 4 by 8 feet) might run $1,800 to $2,500. Larger areas, multiple joists, or work that requires temporary support beams will cost more. Access matters too. If the basement is open and dry, the work is straightforward. If you have a crawlspace, tight access, or the damage is under a kitchen or bathroom, the price goes up. Call (314) 338-6837 with details about the area and we'll give you a ballpark.

Do I need a permit to replace a load-bearing wall or beam in St. Louis?

Yes. The City of St. Louis Building Division requires a permit for structural work, including removing or altering a load-bearing wall, replacing beams, and replacing floor joists that affect the structure. Beam sizing and load calculations for a load-bearing alteration typically require a licensed structural engineer and engineered drawings. We can help you understand what needs permitting and coordinate the application, but you'll need to hire a structural engineer separately. Call the City of St. Louis Building Division at their permit office to confirm requirements for your specific work, or we can walk you through it.

My HOA has rules about exterior work. Do I need approval before you start?

Many St. Louis properties, especially in Central West End and Lafayette Square, have HOA or historic district rules. We recommend checking your HOA covenants or contacting your historic district commission before we begin any exterior work like porch repair, deck work, or fascia replacement. We're happy to coordinate with your HOA or submit photos and materials for approval if needed. Property lines and easements can also matter if the work is close to a neighbor's lot. We'll work within whatever restrictions apply.

Are you insured for work at my St. Louis home?

Yes. We are fully insured with general liability and workers' compensation coverage. We carry the insurance you need to have peace of mind while we're working on your property. If damage occurs, we can help you document it for your homeowner's insurance claim, though we can't promise the claim will be approved or that work will be covered. Your insurance company makes those decisions.

What's the best time of year to repair my porch or deck in St. Louis?

Spring and fall are ideal. Winter freeze-thaw cycles and spring thunderstorms can complicate exterior work, and summer humidity is high. That said, if you have active wood rot or termite damage, waiting for the perfect season usually means more damage. We work year-round. If you spot a problem in winter, we can often make temporary repairs and schedule the full work for spring. Call us as soon as you notice soft wood, gaps in trim, or water staining on your porch or fascia.
