Who’s at fault for a "cupping" bamboo floor?
Two and a half years ago I had a Teragren solid strip vertical grain bamboo floor installed on the first floor of my townhouse. About 12 – 18 months after install I started to notice cupping of the boards. The problem has gotten worse over time but I’m not yet experiencing loose boards. I’m currently in discussions with the installer regarding how to resolve the issue.
The floor was installed with a glue-down application onto the concrete slab. The installer said they used an adhesive that also acted as a moisture barrier. The warrenty was for three years but the installer has said it doesn’t cover moisture penetration. Clearly, the floor is getting cupped by moisture penetration coming up through the slab.
My question is who is at fault for this issue? Is it the adhesive manufacturer, the flooring manufacturer, the installer or myself? The installer has told me: "This issue (moisture) was not evident at the time of my visual inspection or measured at the time of installation and if it were there, then we would have not installed your floor." I have asked the installer what tests they ran and what were the results but I haven’t received any details. They are a highly reputable installer that is local to my area. They are not a chain or a low-cost company. I chose them because of their reputation in the local community. That said, they’re only offering to replace the floor "at cost" as opposed to free of charge. Is it unreasonable of me to expect a free replacement?
The installer has told me they contacted the adhesive manufacturer and the flooring manufacturer and neither is accepting responsibility (no surprise there). Is it worthwhile for me to pursue further discussions with the installer? Should I call a lawyer or my insurance company? Any advice would be appreciated.
Sorry about your floor.
It really pays to be informed about all projects before you hire anyone to do a job for you and spend money on materials. It seems to me that if you have moisture under your slab, that you could have found that out before you put down anything. Water under the bridge so they say.
If it were me, I would remove the floor.
I would not blame the installer, or the manufacturer, or the glue company.
Noone is to blame.
(except you) because you didn’t thoroughly check for moisture before you decided to put down a floor.
