Wide plank laminated with foam underlay on basement slab with engineered hardwood with regular wax paper underlay on main and 2nd.
Efloor was recommended by our architect and we agree with others that their sales staff was great to deal with. A little disappointed more people don't put up reviews frequently here - whether good or bad.
We dealt directly with Aaron and had Liviu and his team install. Aaron spent considerable time helping us select a good product during the supply issues over the COVID pandemic and was very helpful in helping us choose.
Laminate was arranged and installed under a GC that we parted ways with, yet Aaron agreed to complete the unfinished part of the laminate and continue with hardwood at the price negotiated under the GC. Given the stranglehold GCs can have on their suppliers, this brought my rating from a 9 to a 10. Not every supplier continues with the 'little guy' (that's you homeowner) due to loyalty with the GC.
Liviu was wonderful: explained the process, touched up things that needed touching up and sanded some of the underflooring that the GC didn't get level. He had great customer service, crafted some great nosing and hardwood vents and was patient as we installed in sections in order to move items around. He made me replace the protection tape I put on the hardwood afterwards to ensure I used one that wouldn't damage the surface. :)
