Recently one of my client’s neighbors asked me to look at his newly installed Retaining Wall that was built across the front of his home. He commented several times about it being tall enough to see and with the type of blocks used it was nice and straight, and that it was installed for a good price. He had told me that his carpenter knew a couple of guys that could get him a good deal. He could probably tell by the look on my face that something was amiss. He again asked me what do you think? Well? I told him that indeed the wall was straight and level, too. I told him that the material used was o.k., but that he may have problems with his house in the future. I had to explain to him that the wall was really too high for his foundation. The finished level was 4” – 6” above the bottom of the siding. Once the wall was backfilled, the bottom of the house would be covered and not allow for proper ventilation of the siding. This would hold in moisture and could develop into a mold problem or rotting of the interior wall structure and sheathing. I could tell he was disappointed in my statements because he really liked the height of the wall because he “could actually see it”. He wanted to know what would happen if he just didn’t backfill the wall all the way up to the top. This is a good question and not an uncommon one. As time goes by, most people will eventually fill in the void with mulch, plantings… even if it is not by choice, over the winter months the void may will with snow or ice. That’s when the problems could arise. In my opinion, don’t let anyone build up on your house. Let the house breath and you will be happier later.
