Baseboard installation

Baseboard installation is the last thing anyone looks at and the first thing everyone notices when it is wrong. A corner that has opened a sixteenth of an inch, a run that dips away from the floor halfway down a hallway, a nail hole nobody filled before the painter came through. Our carpenters cut it, cope it, fasten it into framing and caulk it before a brush ever touches the walls. That order matters, and most of the complaints we get called out to fix trace back to somebody reversing it.

This is small work, handled by the W2 crews in the Repairs division rather than the design-build side. One room or a whole floor, stock profiles, painted or primed. It sits under trim carpentry repairs along with casing, shoe and the rest of the finish work that gets installed after the drywall is done and the floors are in.

What a baseboard run has to do at the floor

Baseboard covers the expansion gap at the perimeter of a floor. Wood moves, subfloor moves, and the installer leaves a deliberate space so the floor can breathe against the wall without buckling in August. The base hides that gap and takes the beating from vacuums, mop handles and dog crates. It is a wear surface first, which is why fastening deserves more attention than profile.

It also has to bridge two surfaces that are almost never parallel to each other. The wall leans, the floor sags, and the trim is a straight stick of primed pine or MDF that has no interest in either. Every technique below exists to solve that one problem.

The gap under your base is the floor moving

In a settled Ypsilanti or Ann Arbor bungalow you can slide a quarter flat under the base in the middle of a wall while both ends sit tight. Homeowners assume the trim was cut short. It was not. The floor dropped over a beam pocket or a post that has taken on a little of the house, and the base stayed where it was nailed.

Caulk fails at that gap because caulk cannot span a quarter inch and stay flexible through a Michigan winter. It cracks, it yellows, and you see the crack from the doorway.

Shoe molding closes it. A three quarter inch shoe is flexible enough to follow the floor while the base above it stays level and straight, and it gets nailed into the base rather than the floor so the floor can still move under it. That is the fix. If the dip is severe enough that shoe will not cover it, the problem is structural and belongs in a conversation about floor repair before anybody talks about trim.

Coped inside corners hold, mitered ones open

An inside corner cut as a miter is two pieces of wood meeting at forty five degrees, relying on the wall being square. Almost no wall in a house built before the war is square. Worse, the joint opens seasonally. Wood shrinks across its width in the dry months, the two halves of the miter pull apart, and by February you have a dark line in the corner of the living room.

A coped joint puts one piece flat into the corner and cuts the second piece to the exact profile of the first, so the face of the second board rides on top. When the wood shrinks, the coped piece slides slightly and the joint closes into itself instead of opening. Our crews cope every inside corner. Outside corners get mitered, glued and pinned from both faces, because an outside corner has no other option and the glue is what keeps it closed.

Scribing base to a floor that is not level

Shoe solves most floor variation. Some rooms need more. When a floor falls three eighths of an inch across a ten foot wall, running base level leaves a wedge at one end, and running base to the floor leaves the top edge visibly tilted against the window casing beside it. Neither reads well.

Scribing splits the difference. We set the board where the top edge needs to land, run a compass along the floor to trace the actual contour onto the back of the stock, and cut that line off the bottom. The board then sits tight to a floor that is not flat while its top edge stays true.

It takes longer, and it is the difference between finish work and nailing sticks to a wall. On a kitchen or bath where the finished floor is tile set on a mortar bed, scribing is often the only way to close the line.

What comes off the wall with the old base

Here is the part we say out loud before we start, because it surprises people. In a house with lath and plaster, pulling old baseboard off takes plaster with it. The base was installed against the lath before the plaster was floated to it, so the plaster has a feathered edge sitting on the top of the trim. Pry the trim and that edge crumbles in a ragged line six inches up the wall.

We score the paint line with a knife first and pull slowly with a flat bar over a shim, which keeps most of it intact. Some loss is normal anyway. That means the honest scope on an older Ypsilanti or Dexter house includes patching, and we quote it that way rather than discovering it on the second day. Larger areas get handled as drywall and plaster patching in the same visit, and the patched band gets primed before new trim goes back.

You also find things behind base. Old knob and tube runs, mouse damage at the sill, bare floor that was never finished. Anything electrical stops being carpentry at that moment. We photograph it, we stop, and it goes to a licensed electrician. Our carpenters do not open junction boxes, add circuits or touch ungrounded two wire systems.

Stock profiles, and where this stops being a repair visit

This page covers stock profile baseboard. Primed finger jointed pine, solid poplar, MDF where the room stays dry, in the ranch profiles and simple colonial patterns your local supplier stocks in eight and sixteen foot lengths. If the profile you want is on a shelf, our crews can install it on a repair visit.

The line is real and worth stating plainly. Milled to match a profile nobody stocks any more, built up from three pieces to recreate a tall Victorian base, run in quartersawn oak to match an original stain finish, any of that is custom millwork and historic trim. That is design-build work with a shop drawing and a lead time, not a next business day repair.

Built in benches, window seats and paneling sit on the custom carpentry side for the same reason. If you call us for base and the house actually needs matched millwork, we will say so at the walkthrough and hand you to the right team.

Nail holes, caulk and the order the finish goes on

The sequence is where most baseboard goes wrong, and it costs nothing to get right. Fasten, fill, sand, caulk, then paint. A crew that caulks after painting leaves a shiny bead sitting on top of the wall color that will never match. A crew that skips sanding leaves filler proud of the surface, and every fastener shows as a dimple under a semi gloss.

• Fasteners go into studs and into the bottom plate, never into drywall alone.
• Holes get filled with a lightweight filler that sands flush rather than a putty that stays soft.
• The top edge and every inside corner get a paintable acrylic latex caulk, tooled once.
• Nothing gets caulked at the bottom edge if shoe is going on over it.

We can leave the base primed for your painter or finish it ourselves as part of interior painting work. Say which at the walkthrough, because it changes how we mask and whether we pull the base back off the wall to spray it.

New flooring almost always means new base

Homeowners hope to save the existing trim when the floor changes. Sometimes you can. Usually the numbers work against you. Old base is nailed through paint and caulk into plaster, it splits at the fastener when you pull it, and the profile has forty years of paint buildup that will not match a fresh piece where you need a splice. Removing it intact and reinstalling it costs more labor than new stock.

Height is the other issue. A new floor that sits higher than the old one leaves the base short of where the paint line used to be, and you see the old line above it. A floor that sits lower exposes unpainted trim at the bottom. Either way you are repainting, and if you are repainting you are most of the way to replacing. This is why a hardwood floor installation, a carpet replacement or a finished lower level floor should be scheduled with the trim in mind rather than after the fact.

Rooms where base takes the worst beating

Mudrooms and back halls eat baseboard. Wet boots, salt tracked in from January driveways, and a vacuum swung against the same corner every week. MDF is the wrong material there and we will say so.

Bathrooms are the other problem room. Base behind a toilet or along a tub takes standing water it was never meant to see, and MDF swells into a soft gray mush at the bottom edge that no paint hides. Trim near a tub is one more reason the bathroom repair crew and the trim crew often show up on the same ticket.

• Solid poplar or pine where boots and vacuums hit the same corner.
• MDF only in rooms that stay dry.
• A PVC profile behind a toilet or along a tub.
• Fasteners kept high so the bottom edge is not perforated.

What we will talk you out of

Replacing sound baseboard because one corner opened is not worth your money. That corner gets cut back, a new coped piece goes in, the joint gets filled and the wall gets touched up. Two hours instead of two days.

We will also push back on running new base in a room where the plaster above it is failing. New trim under a wall that is going to be skim coated next spring means pulling the new trim back off or masking around it badly. Do the wall first. The same logic applies to a room where a door is coming out, since door and jamb work changes where the base dies into the casing.

And in any house built before nineteen seventy eight, disturbing painted trim means disturbing paint that may contain lead. Federal rules require a certified firm to follow specific work practices on that work. Ask us about it directly at the walkthrough and we will tell you where the job stands rather than guessing on your behalf.

How a baseboard visit actually runs

We do not take emergency or same day calls. The promise is next business day for the walkthrough, Monday through Friday, eight to four. Someone measures the rooms, looks at the floor with a level, checks what is behind the existing trim at one end, and prices the work with the patching included.

On install day, furniture moves to the middle of the room and floors get covered. Base comes off in order, gets labeled if any of it is going back, and the walls get checked for fastener locations before new stock goes up. Most single rooms finish in a day. A full main floor with shoe and paint runs longer, and we will give you that number before you commit. The work carries a written one year workmanship warranty, and the sequence we follow is the same one described in how we work on every job.

Trim rarely travels alone. The same visit often picks up shelving fastened into framing, a round of closet shelf and rod work, or a handrail added at the stairs. Bundling saves you a second trip charge, and the packaged versions live under our grouped repair packages.

Baseboard installation across Southeast Michigan

We run out of Platt Road and cover Washtenaw, Wayne, Oakland, Macomb, Livingston and Monroe counties. The houses change as you move across that map, and so does the work. The bungalows in Ypsilanti and the older neighborhoods of Ann Arbor are the lath and plaster jobs, with settled floors and studs that are nowhere near sixteen inches on center.

Ranches in Livonia and the Wayne County suburbs around it usually have drywall and level floors, which keeps the scribing minimal. The nineties colonials in Canton and Plymouth have predictable framing and tall stock base, so those jobs come down to profile matching between rooms. Farmhouses outside Saline are their own category, and we look at them in person before quoting anything.

Baseboard shows up constantly in our first month after closing package, in repairs done before a house goes on the market and in turnover work between tenants, because fresh trim changes how a room reads faster than almost anything else at that price.
