How To Fill Gaps Between Stairs And Walls (Easy and Straightforward)

How To Fill Gaps Between Stairs And Wall

If you’ve got a long flight of stairs in your house, you’ll definitely have to deal with the gaps left between the walls and the stairs. These gaps are both ugly and dangerous, thus preventing you from decorating your stairs as beautifully as you’d like. But those ugly spaces don’t have to be there any longer! There are several little tricks that can help fill up these gaps for good. So, let’s see how to fill gaps between stairs and walls using some straightforward methods.

Filling Gap Between Stairs And Wall

The good thing is that you can fill the gap between the stairs and the wall with a variety of materials. In order to solve this problem, you need to ensure that the gap does not exceed 3 cm. If it is too big, you will have water infiltration and moisture accumulation problems. In such a condition, you should use drywall as filler. Otherwise, you can use a sealant for a 3 cm or less wide gap.

1. Drywall

Drywall is probably the most accessible material to fill this type of gap. It’s easy to cut and install, and you can get it in different sizes to ensure it fits perfectly into any space where you need it. It’s also easy to paint or stain to match up with your other walls around the house.

If you’re worried about how much sound will leak through your walls and into other rooms, then you should consider using a thicker type of drywall instead of standard 1/4-inch sheetrock. This will ensure that there aren’t any cracks or holes where sound can escape through the walls into other rooms in your house when someone walks down the stairs.

2. Sealant

When the gap is less than 3 cm, the best solution is to use a special sealant applied on the wall surface after installing drywall or plasterboard. This way, you will make sure that there will be no gaps between your staircase and the walls. After using some sort of drywall to fill the larger gaps, you can use the sealant to seal it for good.

If you consider using a material like plywood or even just regular wood for such issues, it will take more time to fill the gaps between your stairs and the wall. Because correcting the measurements and setting into the gaps is tougher when using these materials. Just make sure you have enough sealant to fill the remaining gaps.

How To Caulk Between Stairs And Walls?

Caulking between stairs and walls is integral to any home improvement or repair project. It helps seal the gaps and cracks between these two surfaces and prevent moisture, dirt, and other debris from entering your home. The process is relatively simple and only requires a few tools and materials.

  1. To start, you’ll need some caulk, a caulk gun, a putty knife, and a clean rag.
  2. Begin by removing any old caulk or sealant from the surface with the putty knife.
  3. Then, cut the tip of the caulk tube at a 45-degree angle to create an opening that’s about 1/4 inch wide.
  4. Next, load the caulk into the gun and apply it to the surface in a continuous bead.
  5. Use the rag to smooth out the bead and remove any excess caulk.
  6. At last, allow the caulk to dry for 24 hours before painting or staining it.

How Can You Fix A Gap Between Stairs And Drywall?

If you have a gap between your stairs and drywall, you can quickly fix it with some caulk. Another way is to use a piece of trim to cover the gap. If the gap is large, you may need to use both caulk and trim to fix it.

  • First, remove any old caulk that may be present in the gap.
  • Next, apply a bead of caulk to the gap, making sure to smooth it out as you go. You may need to apply several coats of caulk in order to fill the entire gap.
  • Once the caulk is dry, you can paint over it to match the rest of your wall.

Frequently Asked Questions and Answers (FAQs)

What Goes Between Stairs And Walls?

We know that stairs are often placed against walls. In many cases, nothing goes between the stairs and the wall. The stair treads, which are the part of the stair that you step on, simply rest on the floor. However, in some cases, something does go between the stairs and the wall. For example, handrails are sometimes placed between the wall and the stairs.

How Do I Fill Gaps Around Stairs?

You already know that one way to fill any gaps around stairs is to use caulk. Caulk is a type of sealant that can be used to fill small gaps and cracks. It is available in various colors, so you can choose one that matches the color of your stairs. 

Another option for filling gaps around stairs is to use expanding foam. Expanding foam is a type of insulation that can be sprayed into gaps and cracks. Cut the excess part of the expanding form to bring a smooth finish.

Final Speech

It’s now clear that filling gaps between stairs and walls is easier than many people think, even if it requires more time. Without the methods mentioned above, another way to cut out the gap between stairs and walls is to fill it with a flexible material like plastic sheeting. Cut this piece to the same height as your skirtings and overhang the part that overhangs the wall. However, the best results will come out using caulk and drywalls.
