The master bedroom laminate had at least two obvious problems. By the chimney flue, the floor was flexing significantly, and by the built-in wardrobe, the floor was butted so hard to the wardrobe it was tilted upwards.
My friendly builder showed up this morning, chippy in tow. Off came the skirting boards (with bare hands even, the job was so poor), and up came the laminate. We found missing underlay, underlay overlaid on underlay, and under the underlay, a nail, a screw, bits of plaster, and an off-cut of laminate.
Don’t ever give MNP Flooring business.
Unfortunately, we won’t be putting the flooring back down, because the roof is leaking 🙁
