My name's Kel.
Is there any sign of water intrusion around the area that's bubbled up?
Is the area that's bubbled up right over a pier that supports a major structural element like a column?
Is the rest of the cabin in good shape?
Meaning the floors are level?
There're are no significant cracks in the foundation?
Have there been any earthquakes in the area?
Hi Kel; thanks for writing:
Very good shape. It is almost new and of generally very high quality. The entire structure was engineered for high snow loads--we sometimes see 15-20' of snow--so all 12-in-12 pitch roofs, extra strong foundation, etc. It was all built strictly to code, and passed all inspections when built in 2005. It was carefully inspected by our insurance company as recently as last Summer, due to very deep snow Winter-before-last. No damage, no cracks, no anomalies.
Again, no. None.
The bubble in the floor does not relate to uneven, sloping or buckled floors. It is clearly filled with only air, can be pressed back down smooth and level. Then it pops back up when you get off it!
Is the flooring real linoleum or vinyl or a laminate?
Is the 2 - 3" bubble figure a measurement or an estimate?
You describe it as a bubble --
is there any other shape at all --
say elliptical following the line of an underlayment seam.
Do you have access to the structure under the floor?
Is the floor built with sawn lumber joists, trusses or Truss Joists?
2-3 inches is the estimated height; the diameter is maybe 4' x 5'
Possibly. Its basically the entire clear space in the (smallish) kitchen
Yes; crawl space trapdoor is only a few feet away; everything looks fine from underneath. Checking on substructure (my brother happens to be there today)
It is sawn lumber 2X10's with 5/8 T&G ply, then 1/2" Underlayment.
The only things I can think of are either the flooring adhesive skinned over slightly before the vinyl was laid and there was a weak bond that's failed
or if it was an acrylic adhesive it may have froze
or the roller wasn't heavy enough
or the vinyl was substandard and the walking surface separated from the backing.
If the vinyl has a pattern a flooring contractor may be able to cut out the bubbled piece and reinstall.
If there's no obvious pattern element to hide the cut then have a new piece of vinyl cut that compliments what's there.
Does this make sense?
Have I answered your question?
If the problem were only the vinyl lifting from the underlayment, I would consider using a hypodermic syringe to inject glue just under the vinyl, but the problem is, the vinyl is still holding onto the underlayment--it's the underlayment which has come away from the subfloor--both are bubbling up together.
I forgot that part.
I'm guessing someone forgot to nail either the subfloor or underlayment in that area.
The piece was tacked, but not fully nailed.
[Might have also used too few too short fasteners.]
So the vinyl in the area will have to be removed.
If you can reuse then three sides need to be cut.
It can then be rolled out of the way on the fourth side.
The underlayment properly nail and reinstalled.
Will need a scarifying machine to go over the old adhesive before reinstalling.
You might get a price for just laying a new floor over the old bubbled part.
That would entail laying new underlayment over the bubble then new vinyl then deal with any transitions.
I don't know what to say.
Almost my entire practice is based on finding unique creative solutions to clients' problems.
Sometimes there no magic.
The vinyl has stretched and it's going to be impossible to relay it so it'll match the rest of the floor.
Most installers with enough skill to reset it probably wouldn't warrant the repair.
Having been in similar situations in the past
sometimes it's less expensive or just slightly more expensive to replace rather than repair. Sometimes replace will look better and last longer than repair.
My experience tells me that's what's going on here. . .
Hope you get it resolved.
I'll opt out.
This reply is for Kel: You have my sincere apologies, Kel. I was given to understand that the "relist" comments were confidential and for JustAnswers staff only. I would NEVER have put it so bluntly otherwise. I apologize for the language and I thank you for your knowledge and professionalism, and for your considerable time on my issue.
