Florissant's mid-century neighborhoods are built on solid bones, but those bones need attention. The brick bungalows, ranch homes, and established subdivisions throughout 63031 rely on wood framing, porches, decks, and trim that face real pressure from our humid St. Louis climate, freeze-thaw winters, and termite season.

St. Louis Carpentry has been serving Florissant and the surrounding area since 2016. We show up to fix the wood problems that matter: soft floors, rotting sills and fascia, termite damage found after an inspection, and structural repairs that keep your home solid. We're fully insured, we work with the same crew from start to finish, and we explain what we find before we price the work.

Carpentry in Florissant (63031)

Florissant's established residential stock, built mostly between the 1950s and 1980s, sits on gently rolling terrain with good drainage in most lots, but the combination of our humid continental climate, spring thunderstorms, and the sheer age of the housing stock creates steady demand for structural and finish carpentry. The brick exteriors hold up well, but wood shows up where it matters most: floor joists and subfloors that can develop soft spots or bounce, sill plates and rim joists that absorb moisture, fascia and soffit that weather and fail, and interior framing that termites find attractive during our humid months. We see a lot of floor joist and subfloor repairs here, along with wood rot in sills, decks, and porch framing. Access to crawl spaces and basements is usually straightforward in Florissant, which makes diagnosis and repair faster and more honest.

We've been doing this work in Florissant and across St. Louis since 2016. We know the neighborhoods, the building patterns, and the specific pathologies that show up in homes built here. We repair and replace wood with the same attention to detail whether the job is a $450 baseboard installation or a $3,500 beam replacement.

How a Job Works in Florissant

You call us at (314) 338-6837 or contact us online with a description of the problem. We schedule a free on-site assessment, usually within a few days. We walk through the affected area, ask questions about what you've noticed, and look at the wood up close. We take photos, explain what we find in plain language, and give you an honest estimate before we commit to anything.

Once you approve the estimate, we schedule the work. For most jobs in Florissant, we can start within one to two weeks. We show up with the same crew, bring our own materials, and do the work carefully. If the job requires a permit (common for structural work like beam replacement or load-bearing wall removal), we coordinate with the City of St. Louis Building Division and handle the paperwork. We work clean, stay out of your way, and explain each step as we go.

When we're done, we clean up completely, walk through the finished work with you, and answer any questions about maintenance or what to watch for going forward. You get a straightforward invoice with no surprises.

Pricing in Florissant depends on what we find and what the wood requires. A finish carpentry job like crown molding or baseboard installation typically runs $450 to $550 to start. Interior door installation or repair runs $350 to $1,000. Wood rot repair in a sill or fascia usually starts around $650 and scales with the size of the damage and how much wood needs to be cut out and replaced. Termite damage repair, discovered after a pest inspection, typically starts at $1,200 because it usually means structural wood has been compromised and needs sistering or replacement. A soft or bouncy floor often points to a joist or subfloor problem, and floor joist and subfloor repair typically runs $1,800 and up depending on how much wood is affected and how accessible the crawl space or basement is. Beam replacement or load-bearing wall removal is structural work and commonly requires a licensed structural engineer and a permit; these jobs typically start at $3,500. The biggest cost factors are the size of the area, how much wood is damaged, whether we can access the work easily, and whether the repair holds or replacement is the honest answer. Call us at (314) 338-6837 for a free estimate on your specific situation.

I had a termite inspection and the inspector found damage in my floor joists. What does that mean, and how much will it cost to fix?

Termite damage in floor joists means the wood has been hollowed out by termites and is no longer carrying its full load. The joist is still there, but it's weaker. We repair this by sistering (bolting a new piece of lumber alongside the damaged joist) or replacing the joist entirely, depending on how much damage there is and what the wood looks like when we open it up. We work from your pest inspection report and repair the wood damage; we don't treat the termites ourselves. That's a separate trade. Cost usually starts around $1,200 for the repair work, but it depends on how many joists are affected and how accessible they are. Call us at (314) 338-6837 with your inspection report and we'll give you a real estimate.

My porch deck is starting to sag and feel soft in places. Is it safe to use, and what's the repair going to cost?

A sagging or soft deck usually means the frame is rotting or the fasteners are failing. It's not safe to assume it will hold, especially if you have kids or pets using it. We need to look at it in person to see whether the structure can be repaired (often by replacing the damaged rim joist, band board, or floor framing) or whether the whole deck needs to come down and be rebuilt. Most deck repairs in Florissant start around $900 and go up from there depending on the size and how much of the frame is compromised. Call us at (314) 338-6837 to schedule a free assessment.

What's the difference between wood rot and dry rot, and how do I know which one I have?

Both are fungal decay, but they look and behave differently. Wood rot (also called wet rot) happens when wood stays damp and develops soft, crumbly spots. Dry rot is a specific type of fungus that can spread through wood even in drier conditions and often leaves a crumbly, cube-like pattern. In Florissant's humid climate, we see a lot of wet rot in sills, fascia, and deck framing where water collects or doesn't dry out. The fix is the same for both: cut out the damaged wood and replace it with new material. We'll identify which type you have when we look at it and explain what caused it so you can prevent it from coming back.

Do I need a permit to replace my deck or repair my floor joists in Florissant?

Permit requirements vary depending on the scope of work and the City of St. Louis Building Division's current rules. Structural work like replacing floor joists, beams, or load-bearing walls typically requires a permit. Deck work usually requires a permit. Finish work like baseboard or crown molding usually does not. We coordinate with the City of St. Louis Building Division on your behalf for any work that needs a permit, and we handle the paperwork. Call us at (314) 338-6837 and we'll tell you straight whether your specific job needs a permit and what the timeline looks like.

I live in a Florissant neighborhood with an HOA. Will they need to approve my deck repair or porch work?

Many established neighborhoods in Florissant have HOA rules about exterior modifications. If your work is visible from the street or changes the appearance of your home, the HOA may require approval before you start. We recommend checking your HOA covenants or calling your HOA board before we give you a final estimate. If approval is needed, we can provide drawings or photos to help you make the case to the HOA. We've worked in HOA communities before and we understand the process. Let us know what your HOA rules are and we'll work within them.

Are you insured? What happens if something goes wrong during the work?

Yes. We are fully insured with general liability and workers' compensation coverage. If someone is injured on the job or property is damaged, our insurance covers it. We take safety seriously and we show up prepared. You can ask to see our insurance certificate before we start work.

What should I be looking for in my Florissant home to catch carpentry problems early?

In Florissant's climate, watch for soft spots or sponginess in porch decks, fascia, or sill plates where water collects. Check your basement or crawl space after heavy rain or spring snowmelt to see if water is pooling. Look for visible gaps or movement in floor boards, or a bounce in your floor that wasn't there before. Inspect the underside of your eaves and fascia for peeling paint or soft wood. Have a pest inspection done every few years, especially if your home is over 50 years old. Small problems caught early are much cheaper to fix than waiting until the wood is completely compromised. If you notice anything, call us at (314) 338-6837 and we'll take a look.
