We had vinyl flooring installed in our hall and kitchen several years ago. Within one year there were nail pops protruding under the floor. This resulted in scratches on the surface. Panagos and Van returned but merely used a hammer and a piece of wood to hammer the nails back down. Soon after the nail pops appeared again. The floor should have been screwed down, not nailed.
I have dealt with many companies over the years. The people at Panagos and Van were very fair, and always delivered a well priced, high quality product. Their level of service was great even many months after the initial installation. I wouldn't hesitate to recommend this company.
