This guide covers the carpentry work that keeps a St. Louis home sound and livable: structural repair of wood that has decayed or been damaged, the replacement or reinforcement of framing members that support floors and walls, and the installation and repair of the trim, doors, railings, and built-ins that make a house feel finished. It is written for homeowners in St. Louis and the surrounding areas who want to understand what carpenters actually do, what to look for when something feels wrong, and how to choose someone to do the work well.
A century of brick construction has made St. Louis a city where wood plays a supporting role. It appears in the interior framing, the porches and decks, the window frames and sills, and all the millwork and trim that a homeowner sees every day. That wood faces real challenges: the freeze-thaw cycles of cold winters, the humidity and termite pressure of hot summers, and the slow settling that comes with age. This guide will help you recognize what is normal wear and what needs attention, and what questions to ask when you call a carpenter.
Structural Carpentry vs Finish Carpentry
Carpentry divides into two distinct kinds of work, and the difference matters when you are asking for a quote or trying to understand what has gone wrong in your home. Structural carpentry is the load path: the floor joists and subfloor that carry your weight, the sill plates and rim joists that sit on the foundation, the stud framing and headers that make up your walls, and the beams and load-bearing walls that hold up the upper floors and roof. This is the skeleton. Finish carpentry is everything visible and fitted: the casing around your door and window jambs, the baseboard and crown molding, wainscoting and built-in shelving, cabinets and vanities, interior and exterior doors, and stair stringers with treads and balusters. This is what you see and touch.
The distinction matters to you for two reasons. First, structural work often requires a permit and inspection by the local building department, while finish work usually does not. Second, a carpenter who does both kinds of work can catch a structural problem that hides behind finish carpentry. A soft spot in a subfloor might not be visible until a baseboard is removed. A sill plate beginning to rot might be discovered only when a window casing is taken off to be replaced. A shop that handles the full scope can address both in one project, with one estimate and one timeline. When you call for a quote, be clear about what you have noticed and where it is, and a good carpenter will tell you whether the work is structural, finish, or both.
How St. Louis Housing Stock Actually Fails
St. Louis is built on brick. For over a century, abundant local clay made brick the default exterior for nearly every residential building: the grand Second Empire and Victorian mansions of Lafayette Square and Compton Heights, the brick two-family flats and rowhouses that line the streets of South City in Soulard, Benton Park, and Tower Grove, the compact brick bungalows and craftsman homes on The Hill, and the stately townhomes of the Central West End near Forest Park. Because brick is durable and beautiful, wood shows up mainly where it has to: in interior framing, in porches and decks, in window frames and sills, and in the trim and millwork inside. This matters because it means that when wood fails in a St. Louis home, it is often a localized problem, not a systemic one. But it also means that the wood that is there has been exposed to a lot of weather and time.
The local climate presents three steady pressures on wood. First, the freeze-thaw cycle of cold winters and spring snowmelt works at joints and end-grain surfaces, opening cracks where water can enter. Second, the humid continental summers create the moisture and warmth that wood rot fungi need to grow, and the termite pressure that comes with heat and humidity. Third, the flat to gently rolling terrain along the limestone bedrock means that water pools and drains slowly, keeping wood damp longer. Add a century or more of gradual settling to these forces, and you get the typical failures you see: soft or probing wood in sills, fascia, and deck framing; springy or out-of-level floors; sticking doors and windows; and the slow creep of decay that advances year by year if left unaddressed. Period homes with original millwork and pre-1978 painted surfaces add the complication of lead paint, which requires careful containment during any work. Mid-century tract homes often have simpler framing but the same exposure to weather and time. Sloping floors and sticking doors in an old building are usually settlement, not failure. Your home has been settling since the day it was built, and that is normal. What is not normal is wood that feels soft, or insect damage found on a pest inspection report, or a floor that has changed noticeably underfoot in recent months.
When to Call a Carpenter, and When It Can Wait
Not every imperfection in a home needs immediate attention, but some signs warrant a prompt inspection. Call a carpenter if you notice wood that feels soft or spongy when you press on it, especially in sills, fascia, deck framing, or floor joists; if a floor has become noticeably springy, bouncy, or out of level in a way that has changed recently; if a door or window jamb is visibly rotted or soft; or if a pest inspection report has flagged insect damage in structural wood. These are things worth looking at soon, not because they are emergencies, but because wood decay and insect damage advance over time, and the longer you wait, the more extensive the repair becomes and the higher the cost. A carpenter can inspect the damage, explain what you are looking at, and give you an honest assessment of whether repair is possible or replacement is the right answer.
Many other things are cosmetic or simply the age of the building. Cracks in painted trim, loose or missing caulk around windows, minor gaps between boards, and cosmetic stains are all worth addressing eventually, but they do not require an urgent call. A slightly sticking door or a floor that was never quite level is usually settlement and is normal in an older home. If you are planning a renovation or refresh, a carpenter can handle these things as part of a larger project. If you are uncertain whether something needs attention, a free estimate can give you clarity. A good carpenter will tell you what needs to be done now, what can be planned for later, and what is simply the character of an older building.
How a Carpentry Project Runs, Start to Finish
A carpentry project begins with a free inspection and a written estimate. You describe what you have noticed, the carpenter examines the work, and you receive a detailed scope of work with pricing. This estimate should be specific: what is being repaired or replaced, what materials will be used, and what is and is not included. Once you agree on the scope and price, the work is scheduled. For structural work such as removing a load-bearing wall, replacing a beam, or altering exterior stairs or decks, a permit is commonly required, and requirements vary by jurisdiction. The carpenter will advise you whether a permit is needed and will help you understand the process. You are responsible for verifying permit requirements with the St. Louis Building Department, as rules and thresholds vary.
When the work begins, the site is protected to contain dust and debris, and if your home was built before 1978, lead-safe work practices are followed to protect your family and the environment. The carpenter works through the scope as agreed, and if the work uncovers additional decay or damage once the surface is opened up, you receive a written change order explaining the additional work and cost. This is common and normal. Discovering more damage behind the surface is one reason to get the work done by someone you trust, because the decision to proceed should be yours, and it should be made with full information and a clear price. When the work is complete, the site is cleaned, and for structural work, the local building department inspection is scheduled. Throughout the project, you should expect clear communication about what is being found, what it means, and what it will cost to address.
Choosing a Carpenter in St. Louis: What to Verify
When you are ready to get bids, there are several things you should verify for any contractor you consider, regardless of size or reputation. First, ask for the contractor license number and verify it yourself with the licensing authority for your jurisdiction. The process and requirements vary, so check the rules that apply where you live. Second, ask for a certificate of insurance naming general liability and workers compensation coverage. This protects you if someone is injured on your property or if damage occurs. Third, get the scope of work in writing. A vague estimate is a recipe for misunderstanding. Ask what happens if the work uncovers additional damage, and confirm that changes will be handled by a written change order, not a surprise bill. Fourth, ask who will actually be on site doing the work. A local carpentry shop typically has the same crew doing the work from start to finish, which means continuity, accountability, and a craftsman who cares about the result. A dispatch franchise sends different crews to different jobs, which can mean inconsistency and a lack of ownership over the outcome.
St. Louis Carpentry is fully insured and holds a City of St. Louis Construction Industry Contractor License. When you call for an estimate, you will work with the same carpenters who will do the work. We can answer your questions about what you are looking at, explain what repair versus replacement means in your situation, and give you an honest assessment of scope and cost. We will get the scope in writing, handle changes through a written change order, and coordinate with the local building department on permits and inspections where required. If you have questions about your home or about a project you are considering, call (314) 338-6837 or request a free estimate.
What a Carpenter Does Not Do
Carpentry has clear boundaries, and it is important that you understand them. We do not offer termite or pest treatment, fumigation, extermination, or any form of pest control. Pest management is a separate regulated trade with its own licensing and expertise. What we do is repair and replace the wood that has been damaged by insects, working from your own pest inspection report. If you have had a pest inspection and it has identified insect damage, we can assess the damage, explain what needs to be replaced, and do that work. We cannot and do not make claims about whether an infestation is eliminated, because that is the domain of a pest control professional. Similarly, we do not offer structural engineering services, engineered drawings, load calculations, or engineering opinions. Beam sizing and decisions about load-bearing walls commonly require a licensed structural engineer, and we will build to the engineer's specifications. If your project involves structural changes, we can advise you that a structural engineer is needed and help you understand the process, but the engineer is a separate professional.
We also do not offer mold testing, mold assessment, or mold remediation. Mold can be a building materials issue, and we can address moisture and decay that may be associated with it, but testing and remediation are specialized services outside our scope. We make no claims about health, medical effects, or indoor air quality. Finally, on insurance claims: we can help you document damage for a claim, and we can explain what we find and what it will cost to repair. We cannot promise that a claim will be approved, that work will be covered, or that we will absorb or waive a deductible. Insurance decisions are between you and your carrier. What we can do is give you clear, honest information about the damage and the repair, so you have what you need to work with your insurance company.
