Why is my wall moving?
If your wall moves even a small amount, that is a telltale sign something is wrong. Over time, your brick walls can become weakened due to physical damage, harsh weather, lack of maintenance, and regular wear and tear due to age. Poor construction can also cause problems such as a moving brick wall.
What causes seams in drywall?
Temperature fluctuations can cause the drywall to expand and contract creating stress that cracks the seams. The building is always settling, and this causes stress in the walls that can create a crack in the drywall. Settling can be worse if the building is constructed on fill-dirt.
Why is my ceiling lifting?
The cold winter air has very high relative humidity. The top chords absorb moisture from the air causing them to elongate. With the top chords growing and the bottom chord shrinking, the truss arches up in the middle causing the ceilings to lift off the walls. In the summer, the cycle reverses itself.
Do you leave a gap between drywall?
Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.
What is the cause of popped nails in a ceiling?
When nail-pops show up on the ceiling of the floor just beneath the attic and near a wall intersection, the culprit is a phenomenon known as truss-uplift or a variation of it. The framing is flexing and the drywall in those areas where the nails are popping can’t — hence the popping.
What is an acceptable gap in drywall?
How big a gap is acceptable? Between panels, 1/4 inch is fine. Taping compound and tape will cover it with little difficulty. Putting on a coat of compound before setting the tape will fill the gap.
How do you fix a gap between ceiling and molding?
You can minimize the appearance of the gap by simply squeezing in some silicone caulk between the molding and the ceiling. Unfortunately, it may leave some excess caulk once you apply it. However, you can remedy this by taking a damp cloth and wiping away the excess (use mineral spirits with silicone caulk).
How do you fix a gap between a wall and molding?
The best way to fill the gap between a baseboard and the wall is by using caulk. If the gap is wider than 1/4-inch, you should use a foam strip to fill the gap most of the way and then caulk as the filler for the rest.
How do you fix a gap between ceiling and Moulding?
After crown molding installation, there is usually a large gap between the crown molding and the wall or ceiling. Latex caulk is a good way to fill these gaps. Spread a bead of caulk along the gap with a caulk gun. Smooth the caulk with your finger and let the caulk dry overnight.
What is it called where the wall meets the ceiling?

Can you caulk ceiling cracks?
Caulking the cracks inside the home is the easiest job. You just use a water-based caulk that’s paintable. In the summer, when the crack becomes smaller, the caulk should compress and look pretty good. When you caulk, be sure to use a damp sponge to wipe any and all excess caulk from the ceiling and wall.
