One day I’m going to write the crassly titled book, “Sh*t people do to old houses”.
I’ve seen some real forehead slappers while poking around aged structures. Take, for example, this attic that burnt to a crisp and was left in place by the owners with no reinforcement:
This is a particularly egregious example of homeowner-on-house abuse, but even well-loved homes like the Ordinary House suffer scars of neglect, laziness, or well-intentioned but unknowing house butchery. The structure of our kitchen ceiling (and master bedroom floor) is a perfect example of this last category.
The joists that form the ceiling are rough-sawn 2x8s that span nearly 16′. These days, that same span is barely handled by 2x12s, and not without a fair amount of bounce in the floor. Even with this knowledge, the plumbers who last “remodeled” the upstairs bathrooms saw fit to chop out large sections of the floor joists to fit their pipes. The worst example looks like this:
For reasons that I can’t explain, the plumbers drilled away nearly half the width of the joist for a distance of about 6″. If that wasn’t bad enough, when faced with the fact that the shower drain was directly above the same joist, rather than simply move the shower, they cut a deep notch to allow the pipe to pass through it. For all intents and purposes, this joist had zero structural capacity once this was done. In an attempt to patch up their mess, the builders positioned a section of LVL (a very strong type of engineered lumber) next to the joist and bolted the two pieces of wood together. Then they notched that. [rolling eyes]
Many of the adjacent joists had similar notches. It’s a testament to the resiliency of wood structures that this floor didn’t sag any more than it did.
While we’ve got the kitchen ceiling down, we’re replacing the upstairs plumbing. Knowing that we’d need to make more holes and notches to get the new plumbing in the floor, the plumber stopped his work so that we could assess the situation. I quickly made up my mind that we needed to reinforce the existing structure with new full-length “sisters”, joists that are glued and screwed to the existing lumber.
In order to run the new plumbing, I decided that we would build a completely separate ceiling structure below the existing one. Fortunately, there is enough height between floors in this part of the house that we can have two ceilings and still pull out a 9′ finished ceiling height.
Last Monday, the plumbers came and ripped out all the upstairs plumbing. The next day, a good friend and contractor colleague began reinforcing the existing ceiling and building the new one. We’re fortunate that the downstairs bathroom has a shower, so we’ve been able to bathe. Yesterday, the plumbers began piecing together the new pipes.
It’s decidedly unsexy work, but sexy’s not worth it without the peace of mind of knowing that our floors are strong and our pipes are leak-free. In my next post, I’ll show you what the finished ceiling looks like.
