Q: I want to work on my foundation. I want to dig out my crawlspace into a full basement and stuff like that. How hard is it?
A: Have fun.
Foundation work is serial killer work. You feel grim and mean. You work in the dark and mix tubs of concrete by the light of flickering bare bulbs. You dig dirt with shovels and spades. And when the work is so tight that you cannot use shovels, you switch to hand trowels. And then you resort to the most base level, clawing the dirt with your fingernails.
You are in the tradition of the John Wayne Gacys of this world, late-night work in the earth. There is little difference between you and them, except you’re not burying bodies.
Every shovel-swing is another toast to the John Wayne Gacys of this world.
And somewhere there is a bare bulb swinging on a cord.
And for some goddamned reason, Elton John’s “Yellow Brick Road” playing on continuous rotation on the stereo.
Pure madness. Your wife is visiting relatives in Cincinnati, and any thing could happen. Any damn thing.
Q: My floor slopes and is out of level. One end is noticeably higher than the other end. Peas roll off the plate! How can I fix it? Can I use levelling compound or is something more “serious” required…and I do not look forward to your answer because I’m afraid what it will be.

A: It’s one thing to have a floor with occasional depressions and gaps; it’s another thing when the entire floor slopes in one direction or the other.
You have to ask yourself: Is this a flooring problem or a structural problem? Because when the slope is pronounced–indeed, when we use the word slope at all–it’s no longer a flooring problem. It’s a problem with joists, structure, foundation. All that big, hairy, scary stuff. So what to do?
Flooring Slopes to the Center – Sagging Floor
If you’ve got a floor that slopes inward–from the perimeter to the center of the room–you’ve got sagging joists. Your fix goes beyond using leveling compound. You’ll need to strengthen the floor joists and even add beams and piers underneath–can you handle it? Depends on how hardy you are; most homeowners will call in a contractor at this point.
Or if you can determine that the joists are structurally sound (i.e., not quickly rotting away), you can “sister” the joists, which does two things:
- Strengthens the joist.
- Provides a new, level surface for your subfloor–you’re essentially circumventing the whole “slope” factor and running level boards next to the sloped ones.
Good thing: it works. Bad thing: it entails ripping up the entire floor–finish flooring and subfloor alike.
One End Slopes to the Other End – Foundation Subsiding
It’s a larger problem when one end of the floor is higher than the other end. This means a subsiding foundation, and bigger construction work. You will need to call in a contractor–not necessarily a foundation company, but just a competant contractor–and jack up the lower end of the house, insert beams, and lower the house. Simple, huh?
If the floor isn’t too far out of level, you might be able to insert tapered wood shims atop the joists and re-install the floor. By “not too far out of level,” I mean something like half an inch vertical per ten feet, roughly. Again, you’re ripping up the entire floor (bad thing) and once your fix is completed, you have other problems to deal with, such as:
- Installing new baseboards and trim to accommodate this out-of-square room.
- A noticeably different look to the room. For instance, windows on the “corrected” side with be closer to the baseboards than on the other side. The human eye can pick up these differences.
