Philadelphia's rowhouses, trinity homes, and Victorian twins are built on wood that's been holding up the city since the 1900s, and it's still holding strong, but moisture from our humid summers and the occasional nor'easter finds its way into sill plates, fascia, and deck frames every year. Philadelphia Carpentry has been repairing that wood since 2016, one neighborhood at a time, from South Philly to Chestnut Hill.

When you find soft spots in your floor, see rot creeping into the trim around your windows, or notice your deck frame starting to give, you call a carpenter who knows this city's building stock and won't oversell you a replacement when repair is the honest answer. That's us. We're based in Philadelphia, we work in Philadelphia and the surrounding areas, and we show up with the same crew who finishes the job.

Carpentry in Philadelphia (19102)

Philadelphia sits on flat to gently rolling ground between the Delaware and Schuylkill Rivers, and that means water doesn't drain away as fast as it does on a slope. Your sill plates, rim joists, and the wood at the base of your exterior walls get wet every spring and every time a thunderstorm rolls through in July. Add in the shared party walls on most rowhouses, the tight rear yards, and the brick facades that hold moisture against the wood trim underneath, and you've got conditions that favor wood rot. The good news is that wood rot moves slowly enough that you can catch it, repair it, and keep the house sound for another generation. The bad news is that waiting five years turns a $1,200 repair into a $4,000 one.

We've been doing this work in Philadelphia since 2016. We know the difference between a soft spot that needs sistering and a joist that needs full replacement. We know which permits the Philadelphia building department requires for structural work and which jobs you can start on Monday. We're fully insured, and our crews are registered and L&I-compliant for the work we do.

How a Job Works in Philadelphia

You call us at (267) 477-7458 or reach out online, and we schedule a free on-site assessment. We come to your property in Philadelphia or the surrounding area, we look at the damage, we explain what we're seeing in plain language, and we give you an honest estimate. If it's structural work like replacing a floor joist or removing a load-bearing wall, we'll tell you upfront that a permit is likely required and that you may need a structural engineer. No surprises.

The work itself depends on the job. If you've got wood rot in your sill plate or fascia, we remove the damaged wood, treat the sound wood around it, and install new framing that matches what was there. If your floor is soft and bouncy, we get under the house or into the crawlspace, we inspect the joists and subfloor, and we sister or replace what's failed. In tight Philadelphia rowhouses, that means careful work in confined spaces, and we plan for it. If you're in a historic district like Old City or Society Hill, we coordinate with your local requirements. We protect your property, we work clean, and we leave you with a solid repair and a clear explanation of what we did.

When we're done, we clean up. You walk through with us, we answer your questions, and you've got a piece of your house that will last another fifty years.

Pricing in Philadelphia depends on what you're fixing, how deep the damage goes, and how easy it is to get to. Wood rot repair in a sill plate or fascia typically starts at $650 and goes up depending on how much wood has failed and whether we need to remove siding or other finishes to get at it. Floor joist or subfloor repair starts at $1,800 because it's more involved, more time on the job, and sometimes requires temporary support. Beam replacement or a load-bearing wall removal is structural work, starts at $3,500, and almost always requires a permit and a licensed structural engineer. Finish carpentry like crown molding, baseboard, or interior doors is less expensive, starting at $450 to $550, but the labor is just as careful. The best way to know what your job costs is to call us for a free estimate at (267) 477-7458. We'll look at the site, ask the right questions, and give you a number you can trust.

I found soft spots in the floor of my South Philly rowhouse. How do I know if the joists need repair or replacement?

A soft or bouncy floor usually means the subfloor or the floor joists underneath have absorbed water and are starting to fail. We come out, we get under the house or into the basement, and we probe the wood. If it's just the surface that's soft and the core is still solid, we can often repair it by sistering a new joist alongside the old one, which is less expensive and less disruptive than full replacement. If the wood is rotted all the way through, we replace it. Either way, we address the source of the water first, because a new joist in a wet environment will fail just like the old one did.

My house is in a historic district in Old City. Will the city let me repair my exterior trim?

Historic districts in Philadelphia have strict rules about exterior changes, and the specifics depend on which district you're in and what you're changing. If you're in Old City, Society Hill, or another registered historic district, you may need approval from the local historic commission before you start. We're familiar with these requirements, and we can help you understand what you need. Call us at (267) 477-7458, we'll assess the work, and we'll tell you upfront whether permits or approvals are needed before we give you a price.

What does wood rot repair typically cost in Philadelphia?

Wood rot repair in fascia, siding, or trim usually starts at $650 and goes up depending on how much wood has failed and how hard it is to reach. If the rot has spread to structural members like sill plates or rim joists, the cost goes higher because we're doing more careful work and possibly temporary support. The best approach is a free on-site estimate so we can see exactly what we're dealing with and give you a real number.

I want to remove a wall between my kitchen and living room. Do I need a permit from the city?

If that wall is load-bearing, yes, you almost certainly need a permit from the Philadelphia building department, and you'll need a licensed structural engineer to design the beam that replaces it. We do the carpentry, but we don't do the engineering. We can tell you whether the wall looks load-bearing based on what's above it, and we can help you understand the process, but the engineer and the city are the final word. Call us at (267) 477-7458 if you want to discuss it.

My neighbor's party wall is in bad shape. Who's responsible for fixing it?

Party walls in Philadelphia rowhouses are shared, and the rules about who pays for repairs can be complicated. Generally, if the wall is failing because of your property's condition, you're responsible. If it's failing because of age or the neighbor's property, that's their problem. The best thing to do is talk to your neighbor, get a professional assessment, and consider a written agreement if the repair is going to be expensive. We can give you an honest estimate of what the work costs, and you can sort out the responsibility from there.

Are you fully insured? What if something goes wrong during the job?

Yes, we're fully insured with general liability and workers' compensation. If we damage your property during the work, our insurance covers it. If one of our crew gets hurt on your job, our workers' compensation covers that too. You're protected, and we carry the coverage we need to work safely and professionally in Philadelphia.

It's spring and I see water stains on my basement walls. Should I be worried about wood rot upstairs?

Water in the basement in spring is common in Philadelphia because the water table is high and the ground is flat. It doesn't automatically mean you have wood rot upstairs, but it's a sign that moisture is moving through your house. We'd recommend a walk-through inspection of your sill plates, rim joists, and any wood that's close to grade level. If you catch rot early, repair is straightforward and affordable. If you wait two or three years, the damage spreads and the bill gets bigger. Call us for a free assessment at (267) 477-7458.
