We bought our house last year and a friend of mine pointed out our
sagging floors just in the main entrance area (First floor on top of
the basement). There are around 5 rows of titles (each spanning 15
titles). The first row closest to the living room is perfectly straight
while the second row has a slight downward slope all the way to the
last row closest to the kitchen (less than 1/2 inch depth). It looks
like it has stablized and it's not sagging any more. Both the living
room and our kitchen area is perfectly leveled. Our house is around 18
years old and the tiles don't have any crack or loose grout (except in
some parts as a result of poor tiling). What I want to know is that is
this a bad tiling job? or sagging? Also if it has stablized do I need
to worry about it? It's not noticable at all.
BTW, also there is height fluctuation between floor and the baseboards
anywhere from 0-1/4 inches.
Presumably this wasn't spotted by the surveyor last year. Has this only
happened since you moved in? What is the floor under the tiles made of, wood
or concrete? What happens when someone jumps up and down on the sagging
area, are there any signs of movement in the main entrance area or in the
ceiling of the basement below? If you tap the tiles with a screwdriver
handle does it sound different in the sagging area (hollow) compared with
the non-sagging area (solid)? If it does then the tiles are loose, but that
could just be the tile cement breaking up. If the floor was actually sagging
I would expect ceramic tiles to come loose. You could ask some tiling firms
for estimates for retiling and repairing the floor, to see if they can
identify the problem. Your buildings insurance company may send someone to
inspect in case it is structural failure of the floor.
Thanks for your response. The floors looked extactly the same last year
when we moved in. We didn't get an inspector b/c the house so that we
can get a better deal on the house (to beat the competition). Some of
the tiles are loose but b/c of the poor tiling job on the subfloor
(which is wood and not concrete). Also, when I jump up and down there
is absolutely no movement. Also I went in the basement and placed a
level on all the joists/beams and they're all perfectly level.
Any other feedback is greatly appreciated :)
