ProfessionalBaseboard Caulking

The gap between baseboards and the wall is one of the most visible imperfections in a freshly painted room. We run a clean, consistent bead of paintable caulk along the top edge of every baseboard, tool it smooth, and leave a seamless joint that makes trim look professionally installed.

How it works

Clean and load the gap

We wipe dust and old caulk residue from the joint, load the caulk gun, and run a slow, consistent bead along the top edge of the baseboard.

Tool smooth

We immediately tool the wet bead with a dampened finger or caulk smoother to press it into the gap and create a concave, smooth profile.

Clean and dry

We wipe away excess caulk from both sides of the joint while it's still wet, leaving a clean line that's ready to paint once cured.

We can help

Problems we fix

Caulk cracking at the joint within months because too thick a bead was applied over a gap that flexes with the seasons
Caulk bead that sags or runs because it was applied too fast without enough pressure to fill the gap
Rough, uneven tooling that looks worse than the original gap it was meant to cover
Using silicone caulk instead of paintable latex, making it impossible to paint over

Baseboard Caulking — FAQ

What type of caulk should be used for baseboards?

Always a paintable latex or acrylic caulk, not silicone. Silicone can't be painted and leaves a permanent rubbery line. Paintable caulk dries rigid and takes paint just like the surrounding surface.

How long does caulk last before it needs redoing?

A quality latex caulk in a stable interior joint lasts many years. Joints that flex seasonally — in very humid or dry climates — may need fresh caulk every three to five years.
