Need help with engineered hardwood floor
I recently installed engineered hardwood flooring in my Condo. The work was done by a proper installer who owns a decent sized shop and has some reviews on home star. I noticed that the floor creaks right after the installation. I brought it up to the installer and was told that the floor is new, so it will creak for a bit until everything is settled.
So far it's been a week, the floor still creaks. I don't have any furniture in it because the condo is still vacant waiting for more renovation. I do walk on it quite often everyday when i am working in the condo. It creaks on every step I take. A couple of spots even make cracking/popping sound. I complained to the installer and he sent one of his staff to check out the problem. I basically told him that, I will accept the work if he can find ONE spot that doesn't creak. He walked around and said that the noise will subside when i put furniture in the condo. He was pretty blunt and told me that there is nothing to be done about the flooring, the installation was good, it has nothing to do with the workmanship and the material used.
The concrete slab in my condo is not that flat. There are high spots where you can feel by just walking on it. I also read about how floating floor will always make noise. But I honestly wasn't expecting it to creak on every step. Regarding putting in furniture, there is a small corridor/hallway that leads into the living room. It's narrow and I will never be able to place any furniture there.
I made numerous calls to the installer over the weekend. He finally agrees that, if i can get an independent inspector to check out the floor and write up a report, then they will compensate me based on the report. I.e. they will install it again for free if the report says it's the workmanship. Or they will help me to file warranty claim against the manufacturer if the report says it's the material.
TL;DR
Does anyone know where I can find a certified inspector of this sort? Someone who does inspection of hardwood flooring? Thanks in advance !!
