Why Install Baseboard? Benefits Beyond Aesthetics
Beyond its decorative function, baseboard offers several important benefits:
- Protects walls: Prevents furniture, vacuum cleaners, and daily traffic from damaging the lower part of the walls.
- Conceals imperfections: Covers irregular joints between the floor and the wall, as well as the spaces left by the expansion and contraction of materials.
- Adds aesthetic value: Provides a clean and polished finish that enhances the overall appearance of the room.
- Can hide wires: Some types of baseboard are designed to discreetly hide cables.

Tools and Materials Needed for a Successful Installation
Before starting, make sure you have all the necessary tools and materials on hand. This will save you time and frustration during the process.
-
Tools:
- Measuring tape: To measure the walls.
- Pencil: To mark cuts.
- Jigsaw or miter saw: To cut the baseboard at the necessary angles.
- Brad nailer or hammer and nails: To attach the baseboard to the wall.
- Level: To ensure the baseboard is straight.
- Drill (optional): If you need to install on hard plaster or concrete walls.
- Chisel and tapping block (optional): To remove old baseboard or adjust irregularities.
- Stud finder: To locate wall studs.
- Caulk gun and acrylic sealant: To fill gaps and provide a professional finish.
- Wood filler: To fill nail holes.
- Fine-grit sandpaper: To smooth filled areas.
- Damp cloth: To wipe away dust.
-
Materials:
- Baseboard: Calculate the required amount by measuring the perimeter of the room and adding an extra 10-15% for cuts and errors.
- Baseboard nails: The size will depend on the thickness of the baseboard.
- Construction adhesive (optional): For a stronger hold, especially on uneven walls.
Step-by-Step: Installing Baseboard Like a Pro
Follow these steps to achieve a flawless installation:
Step 1: Wall Preparation
- Ensure the walls are clean, dry, and free of dust or debris.
- Locate the wall studs with a stud finder and mark their location with a pencil. These will be the main points where you'll nail the baseboard.
Step 2: Measuring and Cutting the Baseboard
- Measure the length of each wall where you will install the baseboard.
- Straight Cuts: For straight sections, cut the baseboard to the exact measurement.
- Inside Corner Cuts: Use a miter saw to cut the baseboard at a 45-degree angle, so that the two cuts meet to form a 90-degree angle inwards.
- Outside Corner Cuts: Similar to inside corners, but the cuts should form a 90-degree angle outwards.
- Pro Tip: It's better to cut slightly long at first and then adjust if necessary.

Step 3: Installing the Baseboard
- Place the first piece of baseboard against the wall, aligning it with the floor mark.
- Make sure it is level using the level.
- Nail the baseboard to the wall studs. If you're not nailing into a stud, you can use construction adhesive on the back of the baseboard for added support.
- If using a brad nailer, make sure to adjust the pressure correctly to avoid damaging the baseboard. If using a hammer and nails, nail carefully to avoid marks on the wood.
- Leave a small gap (approximately 1/16 - 1/8 inch) at the corners to allow for expansion and contraction.

Step 4: Joining Baseboard Pieces
- Where two pieces of baseboard meet on a straight wall, you can make a slight bevel cut (a few degrees) to achieve a tighter and less visible joint.
- Ensure the joints are as tight as possible.
Step 5: Finishing and Final Details
- Fill nail holes and joints with wood filler.
- Let the filler dry and then sand it smooth.
- Apply a bead of acrylic sealant along the top and bottom of the baseboard to fill any gaps and give a professional finish.
- Wipe away any excess sealant with a damp cloth.
- Paint or stain the baseboard if necessary. (Link to our guide to painting a baseboard)

Professional Tips for a Flawless Installation
- Pre-paint or stain the baseboard before installation: This makes the job easier and avoids having to paint near the floor and walls.
- Use a cutting template: For repetitive cuts, a template can save you time and ensure accuracy.
- Don't be afraid to use construction adhesive: It can be very helpful on uneven walls or where you can't nail into a stud.
- Invest in good tools: A quality miter saw will make a big difference in the accuracy of your cuts.
- Take your time: Patience is key to achieving a good result.
