Does a House's LEVEL Change, Day to Day?
I'm getting ready to set some ceramic tiles on my kitchen wall for a
backsplash. A few days ago I screwed a couple of very straight 5' steel bars end to end horizontally along the wall studs, to serve as a ledge to mount the first row of tiles on. I was very careful to get the two bars' ends completely flush with each other and level, using a good accurate 48" Johnson level. I checked their level later that night, and again the next day. Both bars were dead-on level. Yesterday I checked their level one more time prior to beginning the tiling and guess what: they're both off somewhere between an eight and a quarter of an inch. I set the level at the same place on the bars each time, and used the same side of the level. The bars can't slip....they're still securely screwed to the studs behind the drywall. And their ends are still flush with each other, so I have a good 10' straight edge along the wall. But what's up with the changing level? This house is a 50 year old single story brick veneer, built on a concrete slab in West Texas. Is it normal for houses or individual walls to shift that much from day to day? Maybe due to temperature variations? |

[remainder snipped] Explanation: you may have used the same *side* of the level each time, but turned it end-for-end for the second measurement. Your level isn't as accurate as you think it is. Put the level on the bars, then turn it end-for-end, keeping it parallel to the floor, and check again. I'll bet it reads level one way, and not the other. |

You swapped the ends, and the level was the same?

[first off- for my money, there is a world of difference between 1/8 and 1/4 in a tile job. You should be thinking in 16ths at least- and 32ds will make it look that much better] If your house settled 1/4 inch in 4' overnight- you might want to put off tiling until you find out what your problem is. If you were in MN,[40below zero-- F. . .brrrr] then maybe it frost heave could do it-- and if it did- then that wall isn't a good place for tiles. I don't think it was that cold in W TX- so I would suspect 1. level got whacked- or 2.operator error. 3. Serious trouble that you need to verify and correct before you tile anything. -snip- This house is a 50 year old single story brick veneer, built on a concrete slab in West Texas.

If your house shifted 1/4" overnight you would of heard walls creaking, maybe plaster cracking, doors and windows would not operate the same, some windows might not even open easily and some doors might catch on the frame, I jacked up a few places and thats what happened. Remeasure it. |

As for why I used the steel bars: They were the straightest objects I
had on hand, plus they already had a lot slots & holes in them so I could run a screw through them and into the studs easily. Anyway, I did as many of you suggested and swapped the ends of the level. Sure enough, both bars are off 1/8" one way and dead level when the level's ends are rotated. Question is: which is correct? I thought I could determine the "accurate" end by checking the bars' level with a couple of 24" Craftsman levels I have. One of shorter levels showed the same thing the 48" level showed (dead on one way and off 1/8" the other) and the other level showed a 1/8" error each, only exact opposite depending on which way the level is orienated. Guess I'll go with the longer level, and be careful to keep it orientated the same way all the time. Like someone above said, tile rows don't have to be laser-precise level. |

You need to check your levels and discard ones that are off calibration. Find a rigid flat surface longer than the level. Place the level on it, check the bubble and note the exact location (centering is not necessary). Reverse the level (180 degrees). The bubble should be in exactly the same location. If the level passes this test it is OK to use it for your projects. If it fails, put it on the curb and get a decent level such as Johnson or similar. Considering the frustration you are having with your work, it would be prudent to buy and use a laser level. Prices range from $20 to $400+ depending on what you want, but the cheapies from Harbor Freight are perfectly accurate for tile work and the like. Even a line level will do a good job. The level hangs from the center of the line and needs two people to get it right. When anchored at one end of the line, the other end is raised and kept fairly tight until the bubble is perfectly centered. Framers and carpenters often use these low cost tools for lengthy measurements. They are usually within 1/8" or so of a laser level line. Joe Joe |

Even a level with broken bubbles makes a pretty good and handy expendable straight edge. Way too useful to put in the trash. 2. Some levels are adjustable. 3. For DIY use, as long as one bubble is good, just label as needed with a Sharpie, so you know which one to use. 4. Precision levels are damn expensive. My 83 YO father has used the same wooden brass-edged 4-foot level (Stanley?) for 40-some years, and it is still plenty accurate enough for residential construction. I use a 5-buck 3-foot garage sale aluminum level, M-D brand, and it reads the same both directions. If you are making money with a tool, it is worth it to get top quality and replace it if less than perfect. If you are just puttering around the house, you can easily get by with something lower down the food chain. -- aem sends... |

If you have now figured out that there are some errors with the levels, why not fix them all so that they give the same reading no matter which way they are placed. Most levels can be adjusted by shifting the vials slightly. |

Maybe due to temperature variations? I'd be more inclined to suspect the different expansion rates of the steel bars and wall structure during temperature swings. Most people use an eyeball-straight 1x4 for what you are doing. Not like you are lining up laser optics or anything, here. Lay a marble on the bar, and see which way it wants to roll. Having said that, this is Texas, and the laws of physics on your infamous clay soil are different at times. Had any rain or big temp swings outside? I'd not lose a lot of sleep over it. Most people set the counter and upper cabinets before they set the backsplash, and fudge as needed so it looks right. Eyes looking at it will key off the back edge of counter and bottom edge of upper cabinets. Tile is seldom gauge-block uniform in size and square anyway. -- aem sends... |
