Baseboard installation: what to know

What the job involves, what changes the price, and what to ask a pro.

What baseboard installation is

Baseboard installation removes old baseboard if present, cuts new pieces to fit the corners, nails them to the studs and finishes with filler, caulk and paint or stain. It makes a clean transition from the wall to the floor, and it covers the expansion gap where flooring meets the wall.

Signs you need it

  • The old baseboard is cracked, chipped, warped or pulling away from the wall
  • New flooring is going in, and the baseboard has to come off and go back on or be replaced
  • The baseboard is too short or too thin for the room, and you want a taller profile
  • There are gaps at the corners and along the floor that dust and pests can get through
  • The walls have been repaired or repainted, and the baseboard no longer meets the new surface

What the pro does

  • Remove the old baseboard carefully with a flat bar and a block, and number each piece so the reinstall fits
  • Measure each wall, mark the stud locations and cut the new pieces, using miters or coped joints at the corners
  • Set the baseboard on the floor, keep it straight and nail it into the studs with finish nails
  • Fill the nail holes and the joints with a wood filler, and sand them smooth
  • Caulk the top edge where the baseboard meets the wall and the bottom edge where it meets the floor
  • Prime and paint or stain the baseboard, then check the corners and the caulk lines in the light

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • Linear footage of baseboard and the number of rooms, including closets and stair runs
  • Profile height and complexity, since a taller or built-up profile takes more fitting
  • Whether the old baseboard is removed and replaced or reused, which changes the labor
  • Number of inside and outside corners that need miters or coping
  • Condition of the walls and floor, including how much patching the old baseboard left behind
  • Finish work, such as paint or stain, and the number of coats

What a written quote should spell out

  • Linear footage by room, with corner count and the corner types listed
  • Profile name, height and material, and whether the old baseboard is removed
  • Nailing method and the nail type used, with the stud fastening stated
  • Fill, caulk and paint or stain products named, with the number of coats
  • Cleanup and disposal of the old baseboard, and the warranty on the install

Questions to ask before you hire

  • Will you reuse the old baseboard or replace it with a new profile?
  • How do you cut the corners, and do you cope the inside corners?
  • Will the baseboard be nailed into the studs, and how do you find them?
  • How do you handle a floor that is not level where the baseboard meets it?
  • What caulk do you use at the top and bottom, and will it be painted?
  • Can you show me a baseboard install you did with a similar floor and wall?

Red flags

  • The pro pulls the old baseboard off and breaks the drywall paper with no plan for the repair
  • The pro cuts the corners at a fixed angle without checking whether the walls are square
  • The pro leaves the baseboard floating on the floor with no stud fastening
  • The pro does not caulk the bottom edge and says the gap is too small to matter

What you can do yourself

Baseboard is a good first trim project for a homeowner with a miter saw and a pin nailer, and removing old baseboard in a single room is a reasonable task if it is done slowly with a flat bar and a block. A long run in a large home, a profile with a complex shape, and a floor that is not level should be handled by an experienced installer.

Licenses and permits

Baseboard installation commonly does not need a license or a permit, since it is finish work. Check with your state or local licensing agency only if the job involves changes to walls, wiring or framing.

Baseboard installation questions

Should I replace the baseboard when I replace the floor?

Usually yes if the old baseboard is damaged, too short for the new floor or has gaps. Ask the pro whether the existing baseboard can be reused and how the new floor height will affect the fit.

What height should baseboard be?

It depends on the room's ceiling height and the style. Taller baseboard suits high ceilings and formal rooms, while shorter profiles suit smaller rooms. Ask the pro to show a sample in the room.

Why do baseboards pull away from the wall?

Usually the baseboard was nailed to drywall instead of studs, or the wall moved. Ask the pro to fasten each piece into studs and to check for the cause of any gap.
