Why does trim separate?

Low relative humidity causes wood molding and shrinking of floorboards. This results in visible cracks. Come winter, your humidity and temperature levels drop, causing the wood to shrink. This results in each piece of your trim separating a bit from its neighbor, cracking the molding and caulking as well as the paint.

How do you fix a gap between a wall and trim?

According to the Home Depot, an acrylic latex caulk with silicone is an excellent wood filler caulk for fixing trim corners or filling large gaps in wood joints. The key to an easy application process is working with a small bead of caulk.

Why do baseboards have gaps?

Gaps between the bottom of the baseboard and the floor usually occur because floor joists sag and foundations settle over many years. In some cases, these gaps are wide enough that they allow air infiltration and can seriously impact your home’s energy consumption.

Why does my trim caulk keep cracking?

When caulking interior trim the caulk is usually wet wiped to remove the excess and to give a clean look.

What causes crown molding to separate from the wall?

Gaps and cracks develop, making the crown molding separate from the wall. Nails and adhesive caulk are no match for temperature-related separation and moisture. The root cause of the problem stems from the contraction or warping of ceiling trusses, the beams that make up structural support of the roof of a house.

Why is there a gap between my walls and floors?
