If you have siding like vinyl, aluminum, steel, or hardie board, we will take a strip down near the middle of the wall and drill into your stud cavities. After that, we will probe the cavities left and right, up and down, to make sure that we are filling everything in the whole cavity. Upon completion, your siding will be put back into place. 

For vinyl siding, you shouldn't even be able to tell we were there. For Aluminum, hardie board, or steel siding, it may require a bit of touch up paint from the homeowner where we cut caulking.

If we come across a fire block, we will remove another strip of siding on the other side of the block and repeat the same process of probing to ensure there's not another cavity. There are times when we find three and four cavities in a wall, up and down, depending on the construction of the home. Once we've filled this cavity with our foam, we're able to plug it and put the siding back on.

If you have wood siding or composite siding, where nails are driven through the surface of each plank, you will need to use paint to touch up the areas where those nails are and where we had to cut the caulking on the sides. However, we will take care of the re-caulking and getting everything put back in place for you.

If you have a brick exterior, we use a five-eighths inch drill bit to drill into the mortar area in each cavity. We typically drill three holes per stud cavity so that we can ensure we've filled the whole cavity. After we fill it with our foam, we'll put the mortar back in to match the exterior of your home as close as possible.

We can work from inside the home if you prefer this method for a specific reason. For example, maybe you have some kind of a stucco exterior that you don't want tampered with in any way. We can certainly come through and work from the interior of your home as well to keep the exterior of your home preserved.

Please understand that if we do work from the interior of your home, you're going to have two-and-a-half inch holes in every cavity, which equates to one hole every 16-inches. And if we find blocking up and down that cavity, we're going to have to drill additional holes to make sure these other cavities are filled properly.
