1. Seal The Gap Between The Pipe And Brick Wall Inside Your Home
These simple steps will help you to get rid of those nasty gaps between the pipe and brick wall of your home:
Step 1: Clean The Surface Properly
if you want perfect sealing around the gap, You need to remove any dirt or debris from the surface by using a dry cloth, a small brush, etc.
You can also use a vacuum cleaner to ensure optimum cleaning. You can apply a trick to clean some hard-to-reach areas. Use a small tube and attach it to the hose of the vacuum cleaner using a tap. This way you are able to clean the whole surface effectively.
Step 2: Use Some Good Quality Sealant Materials
Using the right sealant material is the backbone of the whole repair process. You should aware of what material performs best with which surface.
1. Use Expansion Foam
After cleaning the surface thoroughly, this is the time to use a good quality expansion foam around the pipe.
If the size of the gap is 1 inch then I would recommend using Loctite Tite Foam, this is a kind of expansion foam, which has the capability to expand three times its actual shape post-application.
The Loctite Tile Foam is compatible with most surfaces such as Wood, Brick, Concrete, Metal, and Stone.
2. Use Cement
Cement is a strong, durable, and long-lasting material that can be used to fill gaps and cracks in brick walls.
- The first step is to make a square hole around the gap if the gap is narrow, it helps to apply the cement very well. You can use a hammer and chisel for this.
- The second step is to prepare the mixing area. Find an area that’s free from dirt, debris, and other materials that could get in the way. Make sure there’s enough room for you to stand comfortably.
- The third step is to mix up a batch of cement. Pour some water into the mixing container. Make sure don’t apply too much water otherwise it won’t work. Read the instruction on the cement packaging.
- At last, apply the cement around the gap using your hand. Make sure you wear safety gloves first. You can also use some tools like a margin trowel for this. Apply the cement into the gap to fill all the small-large voids.
- Now it’s time to smoothen the surface, you can use a damp sponge for this.
Step 3: Leave The Surface To Cure Properly
Whatever method you use to seal the gap between the pipe and brick wall, when you have done with the sealing process, leave the surface for a few days to cure it properly.
2. Seal The Gap Between The Pipe And Brick Wall Outside Your Home
After sealing the gaps inside your house, it is time to seal them from the outside. The outdoor atmosphere is totally different from the inside, and you have to use a different sealant to fix the gap between the pipe and the brick wall.
I’ve discussed a step-by-step guide for sealing such types of gaps:
Clean The Outside Surface
You have to clean the outside surface around the pipe and brick wall by using a brush, rags, and some water.
Caulking is the most effective and easy method to fill any kind of gap. Make you use the right sealant for caulking to ensure you don’t face any problems of leakage in the future.
I would strongly recommend using Quikrete Advanced Polymer Concrete Crack Sealant. Most sealants do not work effectively with plastic but Quickrete Advance works. Don’t be confused with the word concrete here, this material is also effective with brick walls. See the screenshot in which a Quickrete Product Expert replied to a customer query regarding this.
The sealant from Quickrete is more effective than the Polyurethane and silicon-based sealant.
It performs well with most plastic pipes. This is a perfect sealant for outdoor which prevents water and ice damage.
Leave It For A Few Days For Cure
After applying the caulk, you have to wait for a couple of days so that it can cure perfectly and become hard and make a leakage-proof cover around the gap.
Now you are all done and have successfully applied the sealant both inside and outside.

Any kind of gaps and cracks need attention and you have to immediately fix them for any future discomfort. Gaps around a pipe through a brick wall are not a big deal to seal, the main thing is you have proper knowledge about the material and some techniques to fix them.
