We installed this in our sunroom in 2012 . The sun room isn’t heated in the winter.We get a little seperation when the January and February extreme cold weather hits. When warmer weather rolls around it tightens right up again. We heat our sunroom on warmer winter days so we basically use it year round. This product stands up great . I would use it anywhere in my house, but my problem is I can not find it . super product if you can find it

Oh dear...you've just discovered the problem with leaving old floors in place. With today's rigid flooring you MUST have the subfloor evened out (flat, smooth, level). If you do NOT...then you get a nasty bouncy, warranty-less floor. Kinda like what just happened. If you do not want to remove the old stuff (the stuff giving you the problems because levelling can't go over it) then you have very few solutions. Carpet being one of them (yikes! Kitchens don't like carpets!). Here are your options: 1. Carpet or sheet vinyl - everywhere 2. Add a subfloor system of some sort with SHIMS all over the place to get you CLOSE to level...and then add leveling compound to the SUBFLOOR SYSTEM...now lay your new floor. This is expensive and usually requires ALL doors to be rehung (exterior and interior) and you may have to renovate the kitchen to get the counter tops 'up' to the regular height as well as deal with built ins like dishwashers and fun stuff like that. 3. Find a primer+leveling material that is ALLOWED over all that old 'asbestos' and vinyl stuff and go from there. Professionals have access to some of these things whereas DIYers are left out in the cold. 4. Remove/remediate what is there and never worry about it again. No matter how you shake this tree, it needs some sort of professional. And it requires some sort of extra $$$$ to go after the ONE THING that is preventing you from getting new flooring in = the old flooring. If the subfloor is as bad as you say it is...there is no easy fix. We usually tell people to do the right thing and remove the old flooring, grind the high spots and fill the low spots until you have a level subfloor. But asbestos and/or vinyl that has been left in place, you leave yourself open to a bad floating floor. If you can live with it...I suggest you leave it and save up over the next 5 years to do this whole thing over again. Or you stop right now, remove everything you have already done and try to deal with the elephant in the room: the old flooring. Until it is gone, you will run into this issue each and every time you need a new floor. Or carpet in the living areas and sheet vinyl in the wet areas and go with it.

I have the Home Depot Lifeproof LPV being put down now. It is a beautiful chevron design in light color wood grain. We are half way though and I want to rip it out. It looks gorgeous and that is the only good thing. The fake wood grooves hold dust and grit. I vacuumed, swept, swiffered mopped and mopped again and finally on hands and knees washed and dried the floor and if you run a hand over it there is still dust and grit. Also, I kept hearing about the good sound quality in a room compared to other hard floors and that it was not as cold as tile. BS on that too. I gave the installers a day off on a Friday hoping I would feel better about it in a few days. Nope. I feel like a fool. I spent almost $10,000 and even though it is gorgeous, I hate how cold it is and the grit just will not go away. I am in such a quandary. It was very difficult to prep the house for the installation. While it would be financially foolish, it may be better to ditch it now. Very said here in Colorado.

I just had Karastan SPC installed by an excellent family owned flooring company with a lifetime guarantee on their installation. Their installers are employees, not subcontractors. They honor their warranty. They will rip out and replace an entire floor, hard surface or carpet, if necessary. The plank has a crushed limestone core. They honor it. In one area, I had 125 square feet of Armstrong Alterna removed. This is a glue down tile. They then skimmed the concrete subfloor to cover the residual glue, as they said that walking on the planks could activate the glue. No shortcuts taken. Not with a lifetime warranty. Most of the concrete subfloor is perfectly level. However, one section has a slant like yours. The installer said the the concrete was lower on one side of the poured joints. Noticeably so. He said with these rigid planks, that would not be a problem. I don’t notice any problem walking on the floor. Did you install a quality rigid plank?
