How to Paint Around Windows and Doors: Tricks for Precision

When painting your home, the windows and doors can make or break the final look. Clean, crisp lines around trim instantly give a professional finish, while messy edges can make the whole job look rushed. Painting around these areas takes a little extra patience and the right approach—but with the right techniques, you can achieve flawless results every time.

1. Prep Is Everything

Before picking up a brush, invest time in proper preparation.

• Clean the surfaces – Remove dirt, dust, and cobwebs from the trim and surrounding areas.

• Fill gaps and cracks – Use caulk to seal any openings around the trim for a smooth, seamless finish.

• Lightly sand glossy surfaces – This helps the new paint adhere better.

• Remove hardware if possible – Taking off door handles, locks, and window cranks prevents accidental paint splatters and makes your job easier.

2. Use Painter’s Tape—But Apply It Correctly

Painter’s tape is your best friend for precision work, but it has to be applied properly:

• Press the tape firmly along the edge where you want a clean line.

• Seal the tape by lightly running a putty knife or your fingernail along the edge to prevent paint from bleeding underneath.

• Remove the tape while the paint is still slightly wet—waiting too long can cause the paint to peel along with the tape.

• Pro Tip if you run a thin bead of caulk along the corner of the tape, paint over it immediately before it dries, then pull the tape right away you will get a crisp line!

3. Choose the Right Brush

When painting around detailed areas, the type of brush matters:

• Use an angled sash brush (1.5" to 2") for better control and smoother edges.

• Look for brushes labeled for trim or cutting in—they’re designed for precision work.

• Avoid using a large, flat brush, which can make it harder to keep paint where you want it.

4. Master the “Cutting In” Technique

Cutting in is the process of painting a straight line without tape, and it’s a skill worth learning:

• Load the brush lightly with paint—too much can cause drips.

• Hold the brush like a pencil for better control.

• Start slightly away from the edge and gently work the paint toward the trim or wall edge.

• Move steadily along the line without rushing; small, smooth strokes give the cleanest finish.

5. Use a Steady Hand and Good Lighting

Painting around windows and doors often means working in shadowy corners or bright glare from outside.

• Make sure you have consistent lighting—consider using a portable work light indoors.

• Take breaks if your hand gets tired; a shaky hand can lead to uneven lines.

6. Protect Glass and Flooring

Even skilled painters get the occasional splatter:

• For windows, apply painter’s tape directly onto the glass, leaving just the trim exposed. If paint gets on the glass, let it dry and use a razor scraper to remove it cleanly.

• For doors, place a drop cloth or plastic sheeting under the area to catch drips and spills.

7. Finish With a Second Coat

For a professional look, don’t stop at one coat.

• Apply the first coat evenly and allow it to dry according to the paint manufacturer’s instructions.

• Lightly sand between coats with fine-grit sandpaper for an ultra-smooth finish.

• Apply the second coat using the same careful techniques for a rich, even color.
